Mind Map and Flowchart and Venn Diagram Squared Off Tutorial

Today’s aim is to add some “schmick” to our Flowchart and Venn Diagram and Mind Map web application on top of the progress up to yesterday’s Mind Map and Flowchart and Venn Diagram Mousemove Tutorial.

Schmick step …

improve the “rubber banding” that yesterday just involved onmousemove and onmouseout overlayed element logic augmented, today, by “already there” HTML div element onmouseover and onmouseout event logic for new HTML div position:absolute;top:[mouseY]px;left:[mouseX]px; via …
var over=false; document.getElementById('dcontent').innerHTML+=antiglowit(("<div" + xciss.replace(acglow,bcglow) + " onmouseover='over=true;' onmouseout='over=false;' id=d" + icnt + " onclick='recxy(event); clickme(this);' class='" + shape + "' style='" + biis + "line-height:20px;background-color:" + bcols[bch] + ";opacity:0.5;position:absolute;left:" + eval(sxoff + xoff + x) + "px;top:" + eval(syoff + yoff + y) + "px;width:" + document.getElementById('idiam').style.width.replace('px','') + "px;height:" + document.getElementById('idiam').style.width.replace('px','') + "px;'></div>").replace(acolour,bcolour).replace(aclass,bclass).replace(aclass.replace("'",""),bclass.replace("'","")));
- for element ID “testrectangle” and “testoval” and “testdiamond” (but not the “testcircle” of Venn Diagrams) we add
- wings outside the proposed element boundaries (where xx,yy below are left,top of mouse move position) …
  var preqwe=''; if (thisshowc == 'testrectangle' || thisshowc == 'testoval' || thisshowc == 'testdiamond') { preqwe='<hr style="z-index:89;width:200px;position:absolute;top:' + eval(-6 + yy) + 'px;left:' + eval(-200 + xx) + 'px;"></hr>'; preqwe+='<hr style="z-index:89;width:200px;position:absolute;top:' + eval(-6 + yy) + 'px;left:' + eval(200 + xx) + 'px;"></hr>'; preqwe+='<hr style="z-index:89;width:200px;position:absolute;top:' + eval(94 + yy) + 'px;left:' + eval(-200 + xx) + 'px;"></hr>'; preqwe+='<hr style="z-index:89;width:200px;position:absolute;top:' + eval(94 + yy) + 'px;left:' + eval(200 + xx) + 'px;"></hr>'; preqwe+='<hr style="z-index:89;height:500px;width:1px;position:absolute;top:' + eval(-200 + yy) + 'px;left:' + eval(0 + xx) + 'px;"></hr>'; preqwe+='<hr style="z-index:89;height:500px;width:1px;position:absolute;top:' + eval(-200 + yy) + 'px;left:' + eval(200 + xx) + 'px;"></hr>'; }

  … seemed to fix problems with Chrome and Opera
- turn off (the non-mobile only) “rubber banding” when a pre-existing element is being hovered over (with an onmouseover event) along with a turning back on with a “no longer hovering” (with an onmouseout event) turning back on (as shown being set up for code below in step 1 above)
  function mmrecxy(event) { var xx=0, yy=0, qwe="", preqwe="", postqwe=""; if (navigator.userAgent.match(/Android|BlackBerry|iPhone|iPad|iPod|Opera Mini|IEMobile/i)) { shocc=''; } else if (over) { document.getElementById('dcursor').innerHTML=''; if (!loosetext) { document.body.style.cursor='pointer'; } } else { // Bulk of mouse move logic goes here } }

The SMS (text messaging) sharing capabilities of yesterday's Mind Map and Flowchart and Venn Diagram SMS Feedback Tutorial just involved ...

feedback words ... but just as with the email sharing capabilities, we think it would be good to additionally offer ...
one co-ordinate set of positional information

... as supplied by the collaborator (back to the originator).

"Easy peasy" you might think, us being there with that Javascript prompt window asking for feedback words with yesterday's work, and we did just say "additionally" above. And we did think it would be easier than it panned out. There were two major issues, the first of which, is a pretty mandatory concern with most software integration like this, but the second, a bit of an eye opener for us, as per ...

finding good intervention points, and doing the correct thing at these points, not interfering with existant workings ...
SMS urls (that become SMS message body content) misbehave for characters like "(" and ")" ... as we eventually tweaked to with the MacBook Pro's "Messages" application's highlight in blue way of voicing concern ...

... the first character of concern here being a ")"

To start on the software integration the obvious "intervention" thinking would go ...

At that Javascript prompt window set up a mechanism the collaborator can tell the web application they want to hang around until the first click they make after any feedback words they supply, that click/touch position representing where they want the originator to know they are interested, and then send off the SMS then.

... and for that we just made it that to add blank character(s) at the end would suffice.

And that's it for the collaborator, but not for the web application, alas. We have to intervene in a way that means something different to the way the SMS is constructed the other way. And that is where we remember ...

via the user clicking on a grid of input type=submit uniquely named (ie. grid_[left]_[top]) ...

... in yesterday's work. If we can slot "grid_[left]_[top]=y" into the URL arguments at the right spot, we'd be rejoining some apt methodologies in the Email positional feedback parts of the code. True, and the spoiler alert is that did work, in the HTML parent's view of it going ...

initialize global variables in HTML as per ...
var gridxy='', gfbk='';
... used by the helper PHP (which leaves its navigation with a reworked version of the code of this HTML) via ...
a crucial PHP codeline going from ...
<?php
// $zzx="Please enter any feedback you want to return to originator at " . str_replace("+"," ",urldecode($_GET['emailcc'])) . "',''); if (fbk == null) { fbk=''; } else { if (fbk.length > 0) { location.href=document.URL.replace('recall=','recim=').replace('.php','.html').split('#')[0] + encodeURIComponent(fbk); } } var xfbk=(fbk"; // ... to ... $zzx="Please enter any feedback you want to return to originator at " . str_replace("+"," ",urldecode($_GET['emailcc'])) . " noting that if you append a blank we will wait around and also pass on your first click position as well.',''); if (fbk == null) { fbk=''; } else { if (fbk.length > 0) { gfbk=document.URL.replace('recall=','recim=').replace('.php','.html').split('#')[0] + encodeURIComponent(fbk.trim()); if (fbk == fbk.trim()) { location.href=gfbk; } else { gridxy=' '; } } } var xfbk=(fbk";
?>
that global variable gridxy becoming one blank crucial to (basis of) "intervention" thinking because wherever we have document.body onclick logic we now (do something like) ...
if (event.touches) { var touches1 = event.changedTouches; var first1 = touches1[0]; x = first1.clientX; y = first1.clientY; } else if (event.clientX || event.clientY) { x = event.clientX; // - elemLeft; y = event.clientY; // - elemTop; } else { x = event.pageX; // - elemLeft; y = event.pageY; // - elemTop; } if (gridxy == ' ') { gridxy='&suggestionxy=' + x + ',' + y; //'&grid_' + x + '_' + y + '=y'; }
making it so that at the end of that document.body onclick logic we can go ...
if (gridxy.trim() != '') { location.href=((gfbk.replace('.html?', dummyencodeURIComponent('.html?grid_') + gridxy.split('&suggestionxy=')[1].split(',')[0] + '_' + gridxy.split('&suggestionxy=')[1].split(',')[1] + '=y' + dummyencodeURIComponent('&')) + dummyencodeURIComponent(encodeURIComponent(' and a click to follow but if you see a black cross as required click there')))) + '&rand=' + Math.floor(Math.random() * 67543); gridxy=''; }
... to make that difference as that ...
HTML webpage call constructs an SMS going to the originator from the collaborator that the originator clicks/touches to navigate back to the HTML webpage with ...
1. any feedback words (for the originator (from the collaborator)) ... and followed by (after a Javascript prompt window) ...
2. an attempt to click at that same position as indicated by the collaborator, else showing a black "x" cross where that is

And so today's tutorial animated GIF shows you a bit of what this SMS Feedback Positioning would look like, and today's progress leaves the changed HTML and CSS and Javascript flowchart.html's live run link there for you to again click a reworded "Email/SMS/Feedback" button, to which you could supply numerical SMS numbers to try out these new SMS communication conduits. Additionally, today, the changed PHP flowchart.php helps out with SMS work, including the optional positional feedback functionality.

What is the link of an "originator/collaborator's computer's web browser" to an "originator/collaborator's computer's SMS client application"? The programmatical or user clicking/touching of an "a" tag's "sms:[SMSnumber]&body=[message]" href attribute (in a web application) is the link we use, but readily admit this technique may not work on every platform. The equivalent idea for an email client application interfacing from a web application is via an "a" tag's "mailto:[Email@Address]?subject=[Subject]&body=[message]" href attribute.

Today's tutorial picture shows you a bit of what this would look like, and today's progress leaves the changed HTML and CSS and Javascript flowchart.html's live run link there for you to again click a reworded "Email/SMS/Feedback" button, to which you could supply numerical SMS numbers to try out these new SMS communication conduits.

And today, for the first time we can remember, we have a new concept of "Animated Emojis" going on. Yes, we've had "emoji overlays" when we presented Emoji Overlay Share Tutorial but they behaved like "stacked up onion layers that had to put up with their lot" whereas "animated emojis" give two emojis the chance to "shine" alternatively "twinkle twinkle little star style", and in between merge to try to describe a concept not currently dovetailing for any one emoji to be the consummate descriptor, by two (with a bit of imagination), courtesy of a small "proof of concept" teste.html ...

But, back to Mind Maps, thanks go to Venn vs Tree Diagrams: which to Use in Your Business's Mind-Mapping Helps Brainstorm Ideas chapter for crystallizing what role they can play ...

If you find that you don’t have a beginning and end point you can use to shape your flowchart, you might need a mindmap. Mindmaps help organize and keep track of thoughts. You organize maps into idea clusters, but everything centers around a main topic.

For example, if your business wants to develop a new feature or product, you’ll need to figure out how you’re going to market it. A mindmap can help you organize all the different possible routes to take and exactly what each route will entail.

To create link lines click/touch two coloured elements and note that if on the way you make a stopover not on a coloured element the resultant link will go from the stopover to the second coloured element position.

Flowchart and Venn Diagram Loose Text Tutorial

In constructing yesterday's Ajax Auto-completion Refinement Tutorial's flowchart tutorial picture via Flowchart and Venn Diagram Glow Tutorial's Flowchart and Venn Diagram web application, we found it had shortfalls performing the "Yes" and "No" (what we call loose) text annotations that help so much to make sense of the inherent logic of the Flowchart. This new "loose text" consists of ...

that same HTML div element type as for the rest of the work ... but ...
drop the CSS styling (including "glow" styling) ... and ...
drop any padding that affects element positioning

... so as to allow the "loose text" be precisely (top left) positioned, as required. And while we are talking about positioning, we found with Venn Diagram positioning it was better to consider the user's click as defining the centre of their circle rather than top left position so that when a second circle is added the user can get close enough (but not within) another circle to achieve the intersections pretty important to many Venn Diagram usefulness scenarios (unless you are modelling "social distancing", that is?!).

In broad brush terms, to make "loose text" happen we ...

introduce new Javascript global variables and new code ...
var loosetext=false; var xoff=0, yoff=0; var prevxoff=0, prevyoff=0; function butlater() { bodyclick=true; xoff=prevxoff; yoff=prevyoff; } function butlaterstill() { loosetext=false; }
introduce a new HTML input element "Text" button as per the HTML (and inline Javascript) ...
<input style=background-color:lightgreen; id=itext type=button onclick="bodyclick=false; event.stopPropagation(); loosetext=true; prevxoff=xoff; prevyoff=yoff; xoff=0; yoff=0; setTimeout(butlater, 1500); " value=Text></input>
and then later if the user has clicked this "Text" button and pressed in a position and entered their text into a Javascript prompt window (and into variable "wording" below) ...
if (loosetext) { shape=""; setTimeout(butlaterstill, 1500); //loosetext=false; }
... happens ahead of Flowchart element Javascript creation ...
if (loosetext) { document.getElementById('dcontent').innerHTML+="<div id=d" + icnt + " onclick='clickme(this);' style='" + biis + "line-height:20px;position:absolute;left:" + x + "px;top:" + y + "px;'>" + wording + "</div>"; }
