Landing Page Autocompletion Blog RegExp Finds Tutorial

Landing Page Autocompletion Blog RegExp Finds Tutorial

Yesterday’s Landing Page Autocompletion Blog Finds Tutorial needed work …

• tweaking for user driven RegExp (via Javascript) blog post finding from the RJM Programming Landing Pages, the old top codeline relying on string matching string length, a concept that does not gel with RegExp …

  
bigs=selcontis.split(new RegExp(('\>' + acsofar.toLowerCase().replace(/\ /g,"\\s")), 'i'));


  … object usage, while the second better codeline uses “</option>” as an end delimiter allowing for any length of blog posting title which receives a RegExp match …
  
//testc='<option ' + bigs[eval(-1 + jbigs)].split('<option ')[eval(-1 + bigs[eval(-1 + jbigs)].split('<option ').length)] + selcontis.split('<option ' + bigs[eval(-1 + jbigs)].split('<option ')[eval(-1 + bigs[eval(-1 + jbigs)].split('<option ').length)])[1].substring(0, ('>' + acsofar).length) + bigs[eval(0 + jbigs)].split('</option>')[0] + '</option>';
testc='<option ' + bigs[eval(-1 + jbigs)].split('<option ')[eval(-1 + bigs[eval(-1 + jbigs)].split('<option ').length)] + selcontis.split('<option ' + bigs[eval(-1 + jbigs)].split('<option ')[eval(-1 + bigs[eval(-1 + jbigs)].split('<option ').length)])[1].split('</option>')[0] + '</option>'; // + bigs[eval(0 + jbigs)].split('</option>')[0] + '</option>';

  … and we add a textbox title so that a user can know this RegExp can be used …
  
document.getElementById('id3').innerHTML=document.getElementById('id3').innerHTML.replace(document.getElementById('tuts').outerHTML,'<input title="To match a third word you would prefix your word entry by \\w+\\s\\w+\\s" autocomplete="off" type=text id=autokey onkeydown="zotzmaybe(event);" style="display:inline-block;z-index:99;width:' + Math.floor(eval(0.4 * eval('' + tutselrect.width))) + 'px;" placeholder="Type tutorial finding word(s)" value="" autofocus=""></input>' + document.getElementById('tuts').outerHTML.split('>')[0].replace('none','inline-block').replace('90%', Math.floor(eval(0.4 * eval('' + tutselrect.width))) + 'px').replace(/\"\ on/g, '" data-on') + '><option id=selfirstopt value=" ">Your finding options below ...</option></select>');

  … to find strings within the blog post title as well as at the start, as needs be … and …

• overcoming the crontab PHP clobbering of our efforts by, for the meantime, shoring up a Javascript defence as mentioned in yesterday’s Stop Press … and …
• mobile platform issues …
  
<select onchange=" if (('' + this.title).indexOf('.') != -1 && this.value.length <= 2) { autokeyway(); } else { if (1 == 1) { document.body.style.cursor='progress'; setTimeout(preChangeTutNow, 7000); } else { ChangeTutNow(this); } }" class='mytuts' id='tuts' style='margin-top:4px;width: 90%; background-color:pink;' title='Tutorials' onblur="if (document.getElementById('selfirstopt').innerHTML.indexOf('autocompletion keyboard') != -1) { document.getElementById('selfirstopt').innerHTML=document.getElementById('selfirstopt').innerHTML.replace('autocompletion keyboard','keyboard autocompletion'); if (this.value.length == 1) { this.title=this.title.split('.')[0] + '.'; this.value=' '; } } else if (('' + this.title).indexOf('.') != -1 && this.value.length == 1) { autokeyway(); }" onmouseout="this.title=this.title.split('.')[0] + '.';" ontouchstart="if (document.getElementById('selfirstopt').innerHTML.indexOf('autocompletion keyboard') != -1) { document.getElementById('selfirstopt').innerHTML=document.getElementById('selfirstopt').innerHTML.replace('autocompletion keyboard','keyboard autocompletion'); if (this.value.length == 1) { this.title=this.title.split('.')[0] + '.'; this.value=' '; } } else if (('' + this.title).indexOf('.') != -1 && this.value.length == 1) { autokeyway(); }" onmousedown="if (document.getElementById('selfirstopt').innerHTML.indexOf('autocompletion keyboard') != -1) { document.getElementById('selfirstopt').innerHTML=document.getElementById('selfirstopt').innerHTML.replace('autocompletion keyboard','keyboard autocompletion'); if (this.value.length == 1) { this.title=this.title.split('.')[0] + '.'; this.value=' '; } } else if (('' + this.title).indexOf('.') != -1 && this.value.length == 1) { autokeyway(); }" onclick=" if (document.getElementById('selfirstopt').innerHTML.indexOf('autocompletion keyboard') != -1) { document.getElementById('selfirstopt').innerHTML=document.getElementById('selfirstopt').innerHTML.replace('autocompletion keyboard','keyboard autocompletion'); if (this.value.length == 1) { this.title=this.title.split('.')[0] + '.'; this.value=' '; } } else if (('' + this.title).indexOf('.') != -1 && this.value.length == 1) { autokeyway(); }"><option id=selfirstopt selected='selected' value=' '>Tutorials (show blog, toggle sort order, click for autocompletion keyboard) ...</option>


… in the changed external Javascript WelcomeIndex.js “all Landing Pages helper” external Javascript code.

Landing Page Autocompletion Blog Finds Tutorial

Two recent themes, and another we like, and enjoy using, combine today, as per …

• the “Landing Page” theme of yesterday’s Blog Posting Filtering Background Date Interfacing Tutorial … along with …
• not that we’ve said it in so many words, but, “the hotkey” work behind the scenes with the web application in the recent Keyboard Based Cursor Image Blog Source Link Tutorial‘s thread of blog postings … and today’s …
• “autocompletion” textbox (and associated dropdown) usage

… (along with good ol’ Javvascript DOM) to improve the functionality of the RJM Programming Landing Page means by which it connects to the RJM Programming WordPress Blog tutorial content.

Autocompletion is good primarily because it is quite a human response to fill in something given a “smaller” start, even given a modern baby’s likely first word …

goo … goog … googl … google

And so, if you have data at your disposal you would not have to wait for the baby to spout “google”. You might gather all the “google” relevant tutorials (and maybe some others) at the “goo” stage (or even earlier).

In our Landing Pages we do have this data available courtesy of the dropdown over to the right and down aways, populated by crontab PHP tasks undertaken each day up at the RJM Programming Apache/PHP/MySql web server. We’ve decided to copy that dropdown’s innerHTML content into the Javascript variable selcontis in the changed external Javascript WelcomeIndex.js “all Landing Pages helper” code below, where we add some new functions as well …


var selcontis='';
var acstr='';
var acsofar='';

function zotzmaybe(evt) {
var bigsih=document.getElementById('tuts').innerHTML.split('</option>')[0] + '</option>';
var bigs=[], jbigs=0, itot=0;
var testc='';
acstr=evt.target.value;
if (evt.keyCode >= 48 && evt.keyCode <= 57) {
acsofar=acstr + ('' + eval(-48 + evt.keyCode));
} else if (evt.keyCode >= 65 && evt.keyCode <= 90) {
acsofar=acstr + String.fromCharCode(evt.keyCode); //('' + eval(-65 + evt.keyCode));
} else if (evt.keyCode >= 97 && evt.keyCode <= 122) {
acsofar=acstr + + String.fromCharCode(evt.keyCode); //('' + eval(-97 + evt.keyCode));
} else {
acsofar+=' ';
}
//alert('acstr=' + acstr + ' and acsofar=' + acsofar);
if (selcontis.toLowerCase().indexOf('>' + acsofar.toLowerCase()) != -1) {
bigs=selcontis.split(new RegExp(('\>' + acsofar.toLowerCase()), 'i'));
for (jbigs=1; jbigs<bigs.length; jbigs++) {
testc='<option ' + bigs[eval(-1 + jbigs)].split('<option ')[eval(-1 + bigs[eval(-1 + jbigs)].split('<option ').length)] + selcontis.split('<option ' + bigs[eval(-1 + jbigs)].split('<option ')[eval(-1 + bigs[eval(-1 + jbigs)].split('<option ').length)])[1].substring(0, ('>' + acsofar).length) + bigs[eval(0 + jbigs)].split('</option>')[0] + '</option>';
if (testc.indexOf(')') != -1) {
itot++;
bigsih+=testc;
}
}
document.getElementById('tuts').innerHTML=bigsih;
document.getElementById('oneopti').innerHTML='Found ' + itot + ' for ' + acsofar + ' below ...';
} else {
document.getElementById('tuts').innerHTML=bigsih;
document.getElementById('oneopti').innerHTML='None found for ' + acsofar + ' ...';
}
}

function muchlater() {
document.getElementById('tuts').size='1';
}

function preChangeTutNow() {
if (!document.getElementById('autokey')) {
ChangeTutNow(document.getElementById('tuts'));
} else if (document.getElementById('tuts').outerHTML.indexOf(' data-onblur=') != -1 && document.getElementById('tuts').outerHTML.indexOf(' size=') != -1) {
ChangeTutNow(document.getElementById('tuts'));
}
document.body.style.cursor='pointer';
}

function autokeyway() {
var tutselrect=document.getElementById('tuts').getBoundingClientRect();
if (!document.getElementById('autokey') && document.getElementById('id3')) {
selcontis=document.getElementById('tuts').innerHTML;
var wasd=document.getElementById('id3').innerHTML.length;
document.getElementById('tuts').style.display='none';

document.getElementById('id3').innerHTML=document.getElementById('id3').innerHTML.replace(document.getElementById('tuts').outerHTML,'<input autocomplete="off" type=text id=autokey onkeydown="zotzmaybe(event);" style="display:inline-block;z-index:99;width:' + Math.floor(eval(0.5 * eval('' + tutselrect.width))) + 'px;" placeholder="Type tutorial finding word(s)" value="" autofocus=""></input>' + document.getElementById('tuts').outerHTML.split('>')[0].replace('none','inline-block').replace('90%', Math.floor(eval(0.48 * eval('' + tutselrect.width))) + 'px').replace(/\"\ on/g, '" data-on') + '><option id=oneopti value=" ">Your finding options below ...</option></select>');
setTimeout(muchlater, 10000);
//alert('' + tutselrect.width + ' was=' + wasd + ' vs ' + document.getElementById('id3').innerHTML.length);
} else if (!document.getElementById('autokey') && document.getElementById('i268')) {
selcontis=document.getElementById('tuts').innerHTML;
document.getElementById('i268').innerHTML+='<input autocomplete="off" type=text id=autokey onkeyup="otzmaybe(this);" onchange="otzmaybe(this); " onblur=" justcheck(this.value); " style="z-index:99;position:absolute;top:' + tutselrect.top + 'px;left:' + tutselrect.left + 'px;width:' + tutselrect.width + 'px;" placeholder="Type tutorial finding word(s)" value="" autofocus=""></input>';
//alert('' + tutselrect.top);
}
}


… the “red rag to a bull” clue that hotkeys are involved being the use of the “onkeydown” (and/or sometimes you see “onkeypress”) keyboard event pointing at function zotzmaybe. In “function zotzmaybe” too, autocompletion compares a hotkey result to data ahead of the display of the keystroke, by which time the incarnation of the original dropdown can be populated with appropriate entries, along with the original calls and ways of functioning. You need to see how a Landing Page caller of the WelcomeIndex.js external Javascript changed to allow for this, as per …

• Tell the cache we’ve changed WelcomeIndex.js …
  
<script async="async" type="text/javascript" src="Welcome_files/WelcomeIndex.js?Lawson=Now&rand=76987"></script>

• Substantially rearrange the tutorial dropdown’s attributes and first option element …
  
<select onchange=" if (('' + this.title).indexOf('.') != -1 && this.value.length <= 2) { autokeyway(); } else { if (1 == 1) { document.body.style.cursor='progress'; setTimeout(preChangeTutNow, 7000); } else { ChangeTutNow(this); } }" class='mytuts' id='tuts' style='margin-top:4px;width: 90%; background-color:pink;' title='Tutorials' onblur="if (document.getElementById('selfirstopt').innerHTML.indexOf('autocompletion keyboard') != -1) { document.getElementById('selfirstopt').innerHTML=document.getElementById('selfirstopt').innerHTML.replace('autocompletion keyboard','keyboard autocompletion'); if (this.value.length == 1) { this.value=' '; } } else if (('' + this.title).indexOf('.') != -1 && this.value.length == 1) { autokeyway(); }" onmouseout="this.title=this.title.split('.')[0] + '.';" ontouchdown="if (document.getElementById('selfirstopt').innerHTML.indexOf('autocompletion keyboard') != -1) { document.getElementById('selfirstopt').innerHTML=document.getElementById('selfirstopt').innerHTML.replace('autocompletion keyboard','keyboard autocompletion'); if (this.value.length == 1) { this.value=' '; } } else if (('' + this.title).indexOf('.') != -1 && this.value.length == 1) { autokeyway(); }" onmousedown="if (document.getElementById('selfirstopt').innerHTML.indexOf('autocompletion keyboard') != -1) { document.getElementById('selfirstopt').innerHTML=document.getElementById('selfirstopt').innerHTML.replace('autocompletion keyboard','keyboard autocompletion'); if (this.value.length == 1) { this.value=' '; } } else if (('' + this.title).indexOf('.') != -1 && this.value.length == 1) { autokeyway(); }" onclick="if (document.getElementById('selfirstopt').innerHTML.indexOf('autocompletion keyboard') != -1) { document.getElementById('selfirstopt').innerHTML=document.getElementById('selfirstopt').innerHTML.replace('autocompletion keyboard','keyboard autocompletion'); if (this.value.length == 1) { this.value=' '; } } else if (('' + this.title).indexOf('.') != -1 && this.value.length == 1) { autokeyway(); }"><option id=selfirstopt title="First option" selected='selected' value=' '>Tutorials (show blog, toggle sort order, click for autocompletion keyboard) ...</option>

• And a small tweak to the next option regarding toggling …
  
<option value=' '>Tutorials (toggle sort order and reselect and click first for autocompletion keyboard) ...</option>

  

… to add in a textbox and dropdown way for a user to use an autocompletion approach to finding topics of interest to filter the RJM Programming WordPress Blog tutorials via, in order to hone in on information and content of interest.

Stop Press

Until we line up our crontab PHP work (which effectively wipes out the tweaks above … sorry, viewers, earlier this morning) … we have the WelcomeIndex.js fix up as per …


function jsonloadf() {
var firsto=false, secondo=false;
var optsare=document.getElementsByTagName('option');

Blog Posting Filtering Background Interfacing Tutorial

With Image Pair Fitting into a Given Dimension Sources Tutorial, below, we identified this WordPress Blog’s TwentyTen theme’s 404.php code as (an example of) …

“code lazy (for us)” “intervention points” that mean most of the hard part of the job is done for you

… means by which we could mimic a little of the brilliant Lorem Picsum‘s modus operandi providing a random image resource, providing our own inhouse RJM Programming WordPress Blog Posting Image resource.

Since then, we’ve leant on that start, nuancing it to allow “filtering” of that total “RJM Programming WordPress Blog Posting Image resource” dataset via a user nominated string that should appear in the Blog Posting Title. This led us, in Landing Page Random Blog Post Topic Link Tutorial to make the change …

Image Pair Fitting into a Given Dimension Sources Tutorial

Thinking “layers of functionality” here, we think that progress onto yesterday’s Image Pair Fitting into a Given Dimension Primer Tutorial would go …

• as well as the wonderful Lorem Picsum resource for beautiful images “source” … we might add …
• new RJM Programming WordPress Blog (that you are probably reading from, now) tutorial picture “source” of images

… the functionality for which we have been trying to envisage for many years, and seeing the excellent Lorem Picsum arrangements being a catalyst, to give it a go.

Kludgy feeling or not, we are happy to be linking into the “last talked about” WordPress Blog Search Within Search Posting Progress Context Tutorial WordPress “URL not found” 404.php code methodologies here, as a great “intervention point”. We often find the biggest joy in web application code modifications is to identify “code lazy (for us)” “intervention points” that mean most of the hard part of the job is done for you, by others (here, that being the great WordPress TwentyTen theme “codex” PHP code helped out by Apache web server .htaccess permalink configurations) before you add your own “situation specific” interventional code.

And so, once at 404.php code, we add new global variables and functions …

… that amount to changes which enable two types of newly functional URLs that, without the changes, used to result in a WordPress webpage explaining that the URL could not be found …

1. a URL such as https://www.rjmprogramming.com.au/ITblog/537/500 will pick a random RJM Programming Blog tutorial picture and show …
   
[image data URI of tutorial picture]#[blog posting title]

   … along with the happy discovery along the way that the “#[blog posting title]” can be tagged onto a base64 data URI and still successfully display the image
2. whereas a URL such as https://www.rjmprogramming.com.au/ITblog/537/500/ will pick a random RJM Programming Blog tutorial picture and show it

… the combination allowing our changed proof of concept CSS (styling) “object-fit” experimenting web application to be now allowing for two sources of image data which the user can select between, themselves, with the RJM Programming WordPress Blog images also containing clickable links back to the WordPress Blog post of relevance. You can also try this here.

Stop Press

And then there is some optional filtering of RJM Programming blog image topic, as we make happen with our changed proof of concept CSS (styling) “object-fit” experimenting web application.

Image Pair Fitting into a Given Dimension Primer Tutorial

One of the most “catered for” part of webpage design involves the display of images. Our recent “stumbling upon” …

• the excellent Lorem Picsum resource for beautiful images suiting a given width x height … had us looking around for an interesting image related theme to “tutorialize” and “stumbled upon” …
• the excellent CSS object-fit Property explanation of CSS “object-fit” property …

… facilitating the interest in the scenario …

• you are presented with “webpage real estate” of a given width x height … into which …
• you want to display two images side by side …

… and in this scenario the use of “object-fit” property values …

Here is where the object-fit property comes in. The object-fit property can take one of the following values:

fill – This is default. The image is resized to fill the given dimension. If necessary, the image will be stretched or squished to fit
contain – The image keeps its aspect ratio, but is resized to fit within the given dimension
cover – The image keeps its aspect ratio and fills the given dimension. The image will be clipped to fit
none – The image is not resized
scale-down – the image is scaled down to the smallest version of none or contain

… creates interesting variety in how you can configure this scenario depending on your (constraint) interest in …

• you are constrained by fact you must see all the image’s content in original aspect ratio … think … contain or scale-down
• you are constrained by fact you must see all the image’s content but not necessarily with original aspect ratio … think … fill or contain or scale-down
• you are constrained by fact that your “webpage real estate” of the given width x height must be filled (by imagery) … think … fill or cover (or (quite often, but not always) none)
• you must keep original image dimensions but clipping okay … think … none
• you must keep original aspect ratio of images but clipping okay … think … contain or cover or none or scale-down

… and then there is …

What happens when you resize your webpage window?
