Hopefully you get the *string* "4711" rather than the number 4711
(unless you parse it). :-)
`innerHTML` works on all major browsers. It was introduced by IE back
in v5 or so, supported by every major browser, and is now standardized
in the HTML5 stuff. Of course, it returns the HTML rather than the
text, so given:
<span id="test"><em>4711</em></span>
$('test').innerHTML will return "<em>4711</em>". If you want just the
text with the tags stripped away, Prototype adds `stripTags`[1] to the
`String` prototype, so $('test').innerHTML.stripTags() will return
"4711".
If you wanted to shorten that a bit, you could add a `text` function
via Element.addMethods[2]:
Element.addMethods({
text: function(element) {
if (!(element = $(element))) return;
return element.innerHTML.stripTags();
}
});
(That's off-the-cuff, but I think it's correct; more on the addMethods
page.)
