Today, with our WordPress TwentyTen themed blog, weโre consolidating the concepts of WordPress Posted On CSS Styling Follow Up Tutorial as shown below, as promised, to make the #hashtagging navigation that goes on so much more practically useful. Letโs recap again, so that you can go over the tautological repetition of concepts โฆ
The improvement, today, is with colour coding the HTML option tag of an HTML select tag, but find this useful feature is no longer cross-browser, though it works in Firefox, at least. With cross-browser issues, you want to check that you are not wasting your time with something, and in terms of this, this useful link put me onto the thoughts that picking at this like a dog over its bone, was not the go (or the went, for that matter) โฆ and that we must not obsess โฆ you got that โฆ no obsessing here โฆ mean to say, you wonโt see us obsessing over an obsession in the near future, or into the next millenium โฆ come to think of it โฆ though cannot rule out the millenium after that, perhaps.
So what is another help on a dropdown to show where you are, apart from the tick provided by some web browsers โฆ well, we decided to indent the #hashtag dropdown item you are on, as well as to try to colour code both the HTML select tag itself and the HTML option tag list (you expand to).
โฆ that all remains true, but yesterday it only applied to the topmost dropdown, but if a user is seriously engaged in #hashtagging navigation, they are unlikely to remain up the top of a webpage for very long โฆ ergo, the need to be there to help that #hashtagging navigation enthusiast. To me there are at least two approaches to solving this issue โฆ
- you can use a CSS (or Javascript DOM) approach to style another dropdown (HTML select element) with styling featuring something like position:absolute;left:50%;top:400;opacity:0.8;z-index:4; (which came into play with PHP Blog Summary Follow Up Tutorial)
- you can use Javascript DOM techniques to change the innerHTML property of relevant HTML elements to slot in new dynamically added dropdowns (HTML select element) that are almost clones of the topmost one created when any one of these dropdownsโ selections is changed by a user who is #hashtagging
We tried option 1 above for awhile, and it may have been possible, but option 2 turned out to be a better idea, and more straightforward to think about and code for, as well. Two small issues or niceties that come into play regarding the โalmost clonesโ affect, is to give each dynamically added dropdown (HTML select element) a unique ID= and insert it so that it shows yellow with the relevant blog posting title option selected (rather than that โPosted Onโ option that began this whole concept).
We need to show you changes made to header.php in itallic bold text below (that adds to the bold text changes as of yesterday) โฆ

So you are here ready to try it out with the first โPosted Onโ dropdown up the top โฆ and see its functionality follow you like a faithful dog โฆ awwwwwwwwwww shucks!
Previous relevant WordPress Posted On CSS Styling Follow Up Tutorial is shown below.
Today, with our WordPress TwentyTen themed blog, weโre following up on the concepts of WordPress Posted On CSS Styling Primer Tutorial as shown below, as we believe in revisits to code, and we can see room for improvement. Letโs recap โฆ
Do you perhaps remember, on this blog, when we presented PHP Blog Summary Follow Up Tutorial as shown below, and talked about the two uses of # (hashtag) and the associated use of the id= HTML parameter?
- you can manipulate HTML via Javascript DOM in terms of individual HTML objects or elements (or tags, if you like)
- you can use them to navigate in a โhashtagโ way via #[id] syntax โฆ by repositioning yourself on your current webpage (as is so readily used in online essays or books in their Table of Contents, perhaps)
In that tutorial we talked about the second point, and again, today, we make use of the functionality of that second point, but this time we keep Javascript DOM integrity.
The improvement, today, is with colour coding the HTML option tag of an HTML select tag, but find this useful feature is no longer cross-browser, though it works in Firefox, at least. With cross-browser issues, you want to check that you are not wasting your time with something, and in terms of this, this useful link put me onto the thoughts that picking at this like a dog over its bone, was not the go (or the went, for that matter) โฆ and that we must not obsess โฆ you got that โฆ no obsessing here โฆ mean to say, you wonโt see us obsessing over an obsession in the near future, or into the next millenium โฆ come to think of it โฆ though cannot rule out the millenium after that, perhaps.
So what is another help on a dropdown to show where you are, apart from the tick provided by some web browsers โฆ well, we decided to indent the #hashtag dropdown item you are on, as well as to try to colour code both the HTML select tag itself and the HTML option tag list (you expand to).
Are we obsessed with dropdowns? Not on your nelly. Though canโt speak for the nelly over there โ>>>
But, seriously (and didnโt you just know there was a but), dropdowns save space and if you have content that becomes important โฆ minimalist looks are fine, but are minimalist looks just that, sometimes โฆ minimalist?
So this is a first step, and tomorrow we open up more practically useful functionality to do with this.
In any case, what needed to change? Well, (and didnโt you just know there was a well), it involved โฆ
- wajax
js (the generic Ajax Javascript code, and its vacant looking mate nothing
js) (changed as per wajaxjs and nothingjs)
- header.php โฆ do fish swim? โฆ and do fish go boldly out where several other molecular beings fear to rest their gills?

So you are here ready to try it out with the first โPosted Onโ dropdown up the top โฆ and, perhaps, with all these hints, you can guess what tomorrow brings improvement wise?
Previous relevant WordPress Posted On CSS Styling Primer Tutorial is shown below.
Do you perhaps remember, on this blog, when we presented PHP Blog Summary Follow Up Tutorial as shown below, and talked about the two uses of # (hashtag) and the associated use of the id= HTML parameter?
- you can manipulate HTML via Javascript DOM in terms of individual HTML objects or elements (or tags, if you like)
- you can use them to navigate in a โhashtagโ way via #[id] syntax โฆ by repositioning yourself on your current webpage (as is so readily used in online essays or books in their Table of Contents, perhaps)
In that tutorial we talked about the second point, and again, today, we make use of the functionality of that second point, but this time we keep Javascript DOM integrity.
WordPress Blog websites are often based on a theme and the theme used for this one is called Twenty Ten. The theme helps you out with PHP templates to give a great foundation for the styling of your website, with a wonderful default look, but that doesnโt mean you have to stop there.
This blog develops blog โthoughtโ threads by calling on previous blog posts a lot to develop a thought process or โthreadโ. Please note that in practice this may endanger your search engine popularity, and havenโt worked out if this is happening, but it may be argued that you are plaguarizing yourself. However, this blog needs to do this, and in doing this, sets up a lot of positional hashtags, which, today, we โharnessโ into more action, by placing them into a dropdown โunderโ the first โPosted onโ wording in the blog post โฆ sorry to non-English speakers until we get around to fixing for this.
Think it is good to have a navigational possibility for # (hashtag) links staying on the page you are on, which makes me feel okay about the code existing in the WordPress Ajax code we have been developing here at this blog.
Our Posted On and contextual help Javascript source code (all in the one place) can be downloaded by wajaxjs which changed as per wajaxjs for these modifications yesterday and today.
Maybe you can make use of # (hashtags) youโve developed?
Previous relevant PHP Blog Summary Follow Up Tutorial is shown below.
To my mind there are two big advantages to the use of the id= HTML parameter usage:
- you can manipulate HTML via Javascript DOM in terms of individual HTML objects or elements (or tags, if you like)
- you can use them to navigate in a โhashtagโ way via #[id] syntax โฆ by repositioning yourself on your current webpage (as is so readily used in online essays or books in their Table of Contents, perhaps)
We probably learn to think that the id=โs we define should all be unique, and who am I to argue โฆ but โฆ and this is a pragmatic but โฆ if we have a webpage exhausted of usage for individual HTML Javascript DOM manipulation possibilities, and there is sorting going on in a table, like weโve been doing recently here at this blog with its Blog Summary, as we talked about with PHP Blog Summary Primer Tutorial as seen below, couldnโt we open up the possibility for id=โs being repeated so that you can still go places despite the fact that you just used one of the (jQuery) sortable table methods to change the order of everything?
Okay, let me put it this way, we know our filename of interest in our Blog Summary starts with a โjโ and it is very recent, so weโve first done a (jQuery) sort via date, but donโt immediately see our โjโ file in our field of view, it would be good to use a hashtag search of #j and lob at the most recent one โฆ that is what we are trying to achieve, and it is achieved here, today, by ditching the idea that all id=โs should be unique and allowing the navigation aspects of id=โs to take precedence (because we will not be needing this particular id= (repeated) system to be used for any Javascript DOM purposes).
All of this is best seen by using the liverun, and hopefully you noticed improved navigation aspects to this webpageโs functionality. If youโre looking for north, though, think maybe you should get a compass โฆ chortle, chortle.
The HTML programming source code for this now could be called getmelistphp and the differences link shows how we got there from the tutorial below.
Previous relevant PHP Blog Summary Primer Tutorial is shown below.
There are two things that often happen for programmers:
- they break a job into its components (often immediately jumping to list the biggest โworryโ)
- they look for ways to achieve the job faster and more reliably (ideas regarding code reuse both internally or externally)
With this in mind todayโs job, which is a GETME code lister for this blog (like a blog summary (updated every day, via cron/curl)) had (or I wanted):
- sortable HTML tables
- data from Linux operating system
To me the biggest โworryโ with this job is the โsortable HTML tablesโ (spend far more time on client side work (โfront endโ) per unit of time of productivity than server-side work (โback endโ)). So, how about we start with a good code basis of โsortable HTML tablesโ โฆ thatโs why weโre showing you the PHP/Javascript JSON Feed or Array Data Primer Tutorial below that we are. Although it looks off-topic, it is very close code-wise, and this leads to another quality (or not) you may want, or not, to do with programming:
- do you mind the old
if (1 == 1) { }
(for code you show to be โback in favourโ) vsif (7 != 7) { }
orif (("to be" || "not to be") == "that is the question") { }
perhaps (for code that is โdeliberately out of favour, but may be of interest, or come back into play laterโ) ? โฆ lots of programmers will not like this, some will be fine with this โฆ am in the latter group, because, to me, it is like โthe comment you make when youโre not making a commentโ
Back to the idea โฆ we do a lot of code download offers with *GETME files here at this blog โฆ so why not summarize all this in a sortable table?
Link to some downloadable PHP programming code โฆ rename to getmelistphp as you wish and here is a link to the live
run and will leave you with the difference in code between this idea and the one of the code below with getmelistphp.
Previous code-relevant tutorial called PHP/Javascript JSON Feed or Array Data Primer Tutorial is shown below.
JSON is a very useful protocol because:
- There is a lot of support in Javascript and the server-side languages, such as PHP or ASP.Net, for JSON-friendly functionality.
- Many website feeds use JSON as their protocol (format) of choice.
Todayโs live run is a simple interface to JSON incoming data and its presentation back to you, either as an HTML table element, or as a validator. Of interest, are the two previous tutorials below. We use an optional method of the first, and the same default input data (via Google Charts) as the second:
- jQuery Sortable Table Primer Tutorial
- PHP/Javascript/HTML Google Chart JSON Data Table Event Tutorial
Along the way, wanted to point out use of:
- Format of JSON data regarding array data โฆ eg.
'{"a":1,"b":2,"c":3,"d":4,"e":5}'
- PHP json_decode() method
- PHP http_build_query() method
- PHP urldecode() method
- Use of an HTML onload Javascript click of an HTML formโs submit button to automate the use of posted data โฆ why post rather than get? โฆ two reasons:
- better security
- there are limits to the amount of get data applied to your address bar urls that comes into play with get scenarios, but not with post scenarios
- Usefulness of online resources such as the JSONLint validator
- The attempts at genericity in the interface by converting posted feed url data into an HTML table presentation (with sortable column data) via the recognition of search specifications for:
- table ID
- table heading data
- table cell data
Here is a download link for some PHP programming source code you could call json_array_postphp
Perhaps Ajax functionality with local JSON data sources is of interest to you, and if this is the case, have a peruse of Ajax Local JSON Primer Tutorial โฆ anyway, hope something here is of interest to you.

A lot of the things people like about the Web are to do with JavaScript and client-side activities. Adding to that experience are Javascript libraries packed full of features. Probably the best known of these is jQuery.
Read more about the powerful jQuery Javascript library here (at its spiritual home) and here (at Wikipedia).
Regarding this topic I really like โJavaScript & Ajaxโ seventh edition by Tom Negrino and Dori Smith pages 437 to 441. The code in this book was followed with quite a few changes. Why change a good thing โฆ welllllll, want to show you some concepts/ideas/buffoonery which weโd like to present in pointy form below (you thought we were going to say โaboveโ didnโt you? โฆ go on! โฆ admit it):
- Can include โold styleโ Javascript โbody onloadโ code within jQuery ready functionality (just checking โฆ because, personally, feel shy about combining the two worlds, but there is nothing wrong doing this, as we do today) โฆ
- Function onloading() which is โold styleโ Javascript is the first thing called from jQuery ready code โฆ why?
- First off please refer to todayโs downloadable HTML/Javascript/jQuery code you could call conjunction_sortable_table
html
- Sometimes you want to use Javascript DOM techniques to dynamically load your document.body.innerHTML contents โฆ so that, perhaps, you can read off a data source of some kind โฆ wouldnโt PHP be sooooo great here?! โฆ Subtext translation: the programmer is lazy and wanted to save coding time by taking an array from the previous tutorial called HTML/Javascript Sentence Conjunction Game Tutorial
- The jQuery ready code fires at the webpageโs body onload event, and you lose the ability to go <body onload=โonloading();โ> but this doesnโt stop you plugging in onloading() up the top of your ready code โฆ are you still awake?!
- Alternative approach is static HTML, and this is presented to you, but is commented out down the bottom of our code provided today โฆ by the way, HTML comment goes <!โ โฆ โ>
- โฆ and how was this derived when a View->Page Source doesnโt show it? โฆ
- โฆ use Firebug (or something like it) and point at the body tag and use โCopy innerHTMLโ to derive this (as per the tutorialโs picture)
- Use of cursor:pointer style property to make a span tag, within an h1 tag act like an a tag
- Recall of ready function for the addsome() Javascript bit awkward, in that code is repeated
- Maybe start reading //stackoverflow.com/questions/999092/can-i-call-the-function-ready-again-in-jquery to see if you can do better
Click onpicture above to go to jQuery page for a (live run) tutorial on the jQuery concept called Sortable Table.
Link to jQuery information โฆ via Wikipedia.
Link to jQuery spiritual home page โฆ via jQuery Foundation.
Link to the great third-party jQuery Sortable Table code is available from the GitHub source control resource here which is a link from here โฆ thanks heaps โฆ isnโt Open Source great?!
Did you know?
The tutorial picture today features the Firefox web browser and a very useful add-on called Firebug which you may want more information about here, which is commonly used to debug client-side Javascript and HTML. As for todayโs usage, Firebug is also extremely useful in deconstructing how a web page was created. The other simple wonderful tool for this is the web browserโs equivalent menu command like View->Page Source (or sometimes equivalent of right-click Page Source). Firebug has a sister product called FirePHP which helps debug server-side PHP and Ajax work.

Here is a tutorial that re-introduces you to Google Graphs API, or Google Chart Tools, and its JSON Data Table functionality which we talked about last time with PHP/Javascript/HTML Google Chart JSON Data Table Import of CSV Tutorial as shown below. Today we extend the functionality talk by adding some event logic for when we click on a table row.
Google Chart Tools provide a perfect way to visualize data on your website. From simple line charts to complex hierarchical tree maps, the chart galley provides a large number of well-designed chart types. Populating your data is easy using the provided client- and server-side tools.
Thanks to the World Bank for some statistics which helped a lot.
