Just Javascript Webmail No Body Tutorial
Were you around and interested in our series of about three blog postings in the series on the theme of creating webpage functionality of some interest, involving no Javascript, when we presented Missing Javascript Audio on Unmute Tutorial? Well, today, it’s the turn of “just Javascript”, which is sort of like what Bookmarklets were about.
With today’s “just Javascript” we have to qualify that a little for our webmail emailing sender application with the architecture …
- parent webpage with only document.head and apart from a document.title just a script Javascript tag of content (using Javascript prompt windows to ask for user information) …
- sending (POSTing) data via …
- Ajax XMLHttpRequest object … as the conduit for …
- FormData object
… to our changed …
- PHP communication emailing tool emailhtml.php … and out to …
- the emailee (out there in the big wide woooorrrrrllllldddd)
Guess we find it interesting that you can do all this (sending of email to emailee recipients) with no document.body in sight.
So take a look at that parent webmail_nobody.html‘s live run link to see what we mean here, and/or watch the video below …

Our “third cab off the rank” following on from yesterday’s Missing Javascript Stop Watch Tutorial “missing Javascript” ideas is an HTML div nesting scenario using just …
- HTML
- CSS
… again, with some or all of the “usuals” below …
- calc method to assist with defining width and height and size dimensions along with operator “+” and/or “-” offset calculation opportunities, and which we’d have used the Javascript window.getComputedStyle and/or [element].getBoundingClientRect methods to cover this (in a much more unwieldy way, as you would probably surmise)
- CSS variables we started talking about here at CSS Variables Primer Tutorial
- CSS3 @keyframes rules we first talked about at CSS3 @keyframes Rule Primer Tutorial that assist with animations that we can make work via …
- CSS3 transitions for scheduled functionality (we’d have used Javascript setTimeout (and setInterval) methods to cover the same “territory”) we first talked about at CSS3 Transition Primer Tutorial … specified with CSS Criteria involving …
- CSS Selectors :after and :before (and often, as for today’s work, with the content: CSS property) first talked about here with WordPress Bullet Point CSS Styling Primer Tutorial … and, today …
- CSS3 transform property’s rotate (and translate and scale) settings (for the puppy dog body movements) … as well as the idea that …
- On non mobile platforms you can set up the playing of “audio” data via the use of an HTML audio tag with the properties …
- controls
- autostart
- loop
- muted
Stop Press
Above is all fine and good for non-mobile but not so good for mobile, so to keep all happy with the one click, still, is to transfer HTML coding from …
<audio id='myaudio' title='Got a sock in my mouth, so you might want to unmute me!' type='audio/mp3' style="display:none;margin-left:-350px;opacity:0.1;" autostart muted loop controls src="Puppy-sounds.mp3" />
… to …
<!--audio id='myaudio' title='Got a sock in my mouth, so you might want to unmute me!' type='audio/mp3' style="display:none;margin-left:-350px;opacity:0.1;" autostart muted loop controls src="Puppy-sounds.mp3" /-->
<audio id='myaudiotwo' title='Got a sock in my mouth, so you might want to unmute me!' type='audio/mp3' style="margin-left:-350px;opacity:0.1;" autostart="0" loop controls src="Puppy-sounds.mp3" />
… and a src= URL data source (as we thank this link for today), or data URI if preferred (which we do for today’s image data from this link, thanks (when we were researching animated GIF data URIs (which we may return to at a later date))
… that sets up the scenario that all the user has to do to hear the audio is to click the “muted” control button, without needing the usual Javascript play() methods … but not on mobile!
Feel free to let the puppy play, that uses the HTML and CSS (but no Javascript) of the_nested.html and based largely on the previous HTML Nested Centering via Multiple Select Tutorial so that these changes reflect how we got to the first draft of today’s work. Maybe some of the ideas are of interest. We hope so!

If you were to ask me which programming component is most vital to web application development, I’d not be Robinson Crusoe in saying …
Without a doubt, Javascript

- meaning of “missing”, as in, it’s hard work writing meaningful web applications without Javascript … but I guess we’ll learn a bit from the exercise of “see where we go”, allowing for the fact, not today, but down the track, that we will allow the use of server-side languages such as PHP
Okay, so, given that restriction, let’s see today’s challenge, to just use, in a web application …
