Can't get getElementsByTagName() to work

Uberbot · 12-07-2008, 04:43 AM

I'm trying to do a proof of concept and I'm having difficulty. I've reduced the code to the bare minimum.

I'm expecting 3 alerts indicating the id's of the 3 <p>'s in the html page. I'm getting the same message all 3 times:
"I am 0 test_p1"
"I am 1 test_p1"
"I am 2 test_p1"

Here is the code:

<body>
<p id="test_p1" m="testme">This is some text</p>
<p id="test_p2" m="xxx">This is some text</p>
<p id="test_p3" m="testme">This is some text</p>

<script>

function do_test () {
var i=0;

var e = document.getElementsByTagName("p");

for (i=0; i<e.length; i++) {
alert("I am "+i+" "+e[i].id);
}
}

do_test();

</script>
</body>
</html>

Could you provide a link instead?

The snippet you've shown works/alerts fine.

I think I must have done something stupid. When I moved it to a openly accessible directory of my webspace, it worked.... I think I can fix it from here. Thanks for the help.

Well, the code does work when it's in a normal page, but when I put the page in a <frame>, it breaks. I know frames are frowned upon, but I have to do it this way. Can anyone think of a reason the SAME FILE doesn't work in a frame?

TIA,
