Javascript document.querySelectorAll Textarea Placeholder Tutorial
Thinking of some great Fred and Ginger types of web application partners we have, at the very least …
- HTML and Javascript
- PHP and MySql
- MySql and phpMyAdmin
- Ajax and FormData
- Webpage and Iframe
- Details and Summary
- Div and Contenteditable
… and today we’ve partnered Textarea and Placeholder because we’ve discovered that Placeholder (on many browsers and platforms) can be multiline by nature. That suits our style, whereby we try not to bombard users with loads of user entries to have to worry about in web applications, where that is at all possible, but rather resort to intelligent user interaction, often based on delimiters, encouraging the one piece (or perhaps two or three pieces) of information to fill in.
Today’s progress (added to that of yesterday’s Javascript document.querySelectorAll User Scripting Tutorial) concerns that user interaction design to our “Testing Out document.querySelectorAll” web application is to …
- replace single line input type=text element with textarea element … and …
- replace single line advice in a single line placeholder attribute with a multiline placeholder “blurb” which includes an example
… and, speaking personally, the relief is incredible, as we have had to grapple with the awkwardness of user entry for days now!
We even styled the placeholder thanks to the advice at W3schools, thanks.
And then we thought we’d allow the user to set the example bit of the placeholder as a “starter” for their real entry via a “two times click on the textarea” set of (on document onload event) logic as per …
function onl(injs) {
if (document.getElementById('myinput')) {
if (document.getElementById('myinput').outerHTML.indexOf('<textarea') != -1) {
var egis=String.fromCharCode(10) + String.fromCharCode(10) + " Example (2xClick) of Einstein Wikipedia Webpage with rounded magenta images and lightblue heading ... " + String.fromCharCode(10) + String.fromCharCode(10) + "http://www.wikipedia.org/wiki/Einstein" + String.fromCharCode(10) + "` img { " + String.fromCharCode(10) + " BORDER-radius:20%; " + String.fromCharCode(10) + " border: 1px dotted magenta; " + String.fromCharCode(10) + " } `" + String.fromCharCode(10) + " function fhlb() {" + String.fromCharCode(10) + " document.getElementById(" + '"' + "firstHeading" + '"' + ").style.backgroundColor=" + '"' + "lightblue" + '"' + "; " + String.fromCharCode(10) + " } " + String.fromCharCode(10) + " setTimeout(fhlb, 2000); " + String.fromCharCode(10);
document.getElementById('myinput').placeholder=document.getElementById('myinput').placeholder.replace(/\|\ /g, String.fromCharCode(10)).replace(' # or ` separate', ' # or ` or first line feed separate').replace(' # or ` and', ' # or ` or first line feed and') + egis;
document.getElementById('myinput').ondblclick = function(event){ ccnt=0; if (event.target.placeholder.indexOf('http') != -1) { event.target.value='http' + event.target.placeholder.split('http')[1]; } };
document.getElementById('myinput').onclick = function(event){ ccnt++; if (ccnt >= 2) { ccnt=0; if (event.target.placeholder.indexOf('http') != -1) { event.target.value='http' + event.target.placeholder.split('http')[1]; } } };
} else {

Another user defined feature we can add to yesterday’s Javascript document.querySelectorAll Absolute URL Tutorial‘s functionality list of …
- CSS user defined selector default styling for relative URL
- CSS user defined styling for relative URL
- Onclick logic related to that CSS selector via Javascript document.querySelectorAll for relative URL
- Popup window lor refresh mode child iframe src then srcdoc overlay techniques for relative URL that is nothing (ie. this web application)
- Absolute URL support as per the top three functionalities above … today we have added …
- User defined Javascript scripting (with the ` character delimiter added in case styling or scripting requires the # character)
Yes, Javascript can be user defined and dynamic in an already running execution via Javascript such as …

Many web applications we present at this blog use what we refer to “inhouse” as …
… as that “suck it and see” client approach to do some of the “if it exists try it” functionality you might think has to involve a serverside language like PHP. No, all the discussion below, ignores serverside anything, but instead dwells on …
- “child” iframe (leaning towards that Client Pre-emptive Iframe) making use of the “fresh start” their “onload” event (and to a lesser extent “onerror”) provides the client (only) programmer …
- initially via “src” attribute … but new to today’s work (at least for us, that we can remember) …
- initially involve src=”data:text/html;base64,[base64HTMLContent]” that …
- (same) “onload” code can redirect that content to another “child” iframe (leaning towards that Client Pre-emptive Iframe) “srcdoc” attribute … and yes, we were not sure until today, but yes …
- “child” iframe (leaning towards that Client Pre-emptive Iframe) that gets its content via “srcdoc” attribute does pass through the “onload” event logic where the “document” object exists (a very happy discovery for us (though we’ve probably been assuming it already in projects up to now))
… this “proof of concept” experimenting being incorporated into our “Javascript document.querySelectorAll” project for scenarios …
For relative URL that is blank (ie. uses this same webpage) suffixes of two blanks refreshes and that of four blanks opens new window and that of eight blanks opens new popup window.

How does the client wooooooorrrrrrrllllllldddd handle base64? Well, for simple data …
Why can’t we manage this new functionality in the one pass through the “onload” event logic? Well, any self-respecting webpage content will contain both apostrophe and double quote characters (let alone line feeds and carriage returns) ( but we can if we can get to a Javascript DOM statement like document.getElementById(‘ifsd’).srcdoc=atob((” + ioissrc).split(‘;base64,’)[1]).replace(‘</bo’ + ‘dy>’, ‘ <style> ‘ + selectorplusis + ‘</style> </bo’ + ‘dy>’); ), making it hard to specify on the Javascript codeline constructing your “child” iframe but now this new functionality uses …

var aconto = (iois.contentWindow || iois.contentDocument);
if (aconto != null) {
if (aconto.document) { aconto = aconto.document; }
