View Full Version : InnerText?

10-03-2003, 05:24 PM
I've 'grabbed' an element using getElementById, now I want to find the text that's inside that element.

I could use innerHTML, but at the moment that returns "<a href="#"> Sample Link </a>" and I'd have to write some kind of parsing program to just get 'Sample Link'.

If there's no property like this, please just tell me, I enjoy the challenge of trying to write programs myself and I'd like to create the parser myself.

Well, there is an innerText (http://msdn.microsoft.com/workshop/author/dhtml/reference/properties/innertext.asp) property but it's IE-only.

Alright, thanks.

Ok, I've written a parser and it works fine, but one more question.

Is there any way, when we have a block of text, to find out how many pixels it is wide on the users screen?

It sounds nice and complicated, so I thought I'd ask before having a go.

By default, I don't think so... But search around here. Good ole' cheesebag put together a custom script that did something like that I believe.

Also, if you wouldn't mind, could we check out your script for getting the text inside an element? :D

Here's my function:

function foo() {
lefts = getElementsByClass('left','e');

var s='', t='', intag;
for (var i=0; i<lefts.length; i++) {
s = lefts[i].innerHTML;
for (var j=0; j<s.length; j++){
if (s[j] == '<') intag = true;
if (!intag) t += s[j];
if (s[j] == '>') intag = false;
alert(t); //Will change this to something more useful eventually

This is the getElementsByClass function that you'll also need (posted by cheesebag on my thread 'getElementById for classes?' a while back. Do a search.)

function getElementsByClass( _class, el_id )
var parent, els, returnArr = new Array(), i = 0;
parent = (el_id) ? document.getElementById(el_id) : document;
els = parent.getElementsByTagName('*') || parent.all;
for (i; i < els.length; i++)
if (els[i].className == _class)
returnArr[returnArr.length] = els[i];
return returnArr;

Alright, cool. Nice job. :thumbsup:

I'll have to look around for that other script cheesebag made... I'm almost positive he made something like that.

Good luck.

I'm not sure if this is exactly what you're looking for, but check this thread (http://www.codingforums.com/showthread.php?s=&threadid=26689) out. That's the one I was thinking of.

Well, that'll return a space, but I didn't think of reading the offsetWidth... heh...

I'll do that and minus the padding etc.

Well, thanks for the help.
