Issue #84 (script.text, Testing Tools, Content, Productivity)
(Skip to the tools section below)
Just this past week, I discovered the text property that is available on any script element in an HTML page. I'm surprised I haven't come across this before, and maybe you're in the same boat.
Let's say we have the following HTML:
Example text inside a script element.
<!-- comment test -->
<p>Example text inside a script element.</p>
Here we have 3 script elements – two with a src attribute set. I've also added a class to each, so I can collect them all without worrying about grabbing other ones I don't want when creating the demo page.
Notice that 2 of the script elements have some content included, the last one also including an HTML comment and paragraph tags. The text property for script elements allows us to grab the contents of the script element, similar to how the textContent property works on regular elements. In his Definitive Guide, David Flanagan says: "This makes a script element an ideal place to embed arbitrary textual data for use by your application." I've heard of developers using hidden textarea elements for this sort of thing, but not a script element.
So our code to grab the text might look like this:
var scripts = document.querySelectorAll('.sc');
And of course, I could store those values wherever I want, but in this case I'm just outputting them to the console. See this demo to test it out, and notice that in that demo, I'm also defining the text content for the 2nd script element, then outputting that after it's set. So it's not read-only.
The stuff I've read on this property, however, seem to be a little contradictory and confusing, and there's definitely a bug in Chrome. Here's a description of my findings:
Maybe I'm misunderstanding something about this property, but I'm going to do some further testing and then I'll file any bug reports with the browsers. If you have any further info, feel free to reply to this email.
- Flanagan seems to imply that the text property is available only on script elements that don't have a src attribute set. My demo disproves that in the 3 main browsers (although maybe I'm just misreading what he says).
- The spec says this property "must return a concatenation of the contents of all the Text nodes that are children of the script element (ignoring any other nodes such as comments or elements), in tree order", however, all 3 browsers return the paragraph element in my demo and Chrome also returns the comment.
- Bugs aside, I believe this property is supported in all browsers, even back to old versions of IE.
