problem clearing innerhtml on mozilla

[ed]

Hello-

i'm having some problems getting innerhtml to clear on mozilla, but it
works fine in ie. my page is setup such that i have a div:

<div id="otherModel" ></div>

on a select from a combo box, in my javascript i execute:
div = document.getEle mentById("other Model");
depending on what's selected in a combobox, i execute:
var inner2 = "<p>Other Model:<br />";
inner2 = inner2 + "<input type='text' id='otherModel' ";
inner2 = inner2 + "size='20' maxlength='30' value='Enter Model'>";
div.innerHTML = inner2;
or simply:
div.innerHTML = "test";

This all works fine independantly; it'll either fill with my textbox,
or the test string. but if the innerhtml is filled with the text box,
then i make a new selection that fills it with "test", it doesn't clear
out the text box.

If i replace the variable inner2 with simple text, everything seems to
work great (but i need a text box!). any insight would be
appreciated...

an example can be seen here:

Here you create a second element with the id 'otherModel', that gives
you invalid HTML.
inner2 = inner2 + "size='20' maxlength='30' value='Enter Model'>";
div.innerHTML = inner2;
A more efficient way of concatenating the text is:

var inner2 = "<p>Other Model:<br>"
+ "<input type='text' id='otherModel' "
+ "size='20' maxlength='30' value='Enter Model'>";

or simply:
div.innerHTML = "test";
You should implement this as something like:

var inner2 ='test';
if ( someTest ){
inner2 = "<p>Other Model:<br>"
+ "<input type='text' id='otherModel_ 02' "
+ "size='20' maxlength='30' value='Enter Model'>";
}
div.innerHTML = inner2;
In other words, set inner2 to some value and then change it if your
logic says to do so - and don't duplicate the ID.

This all works fine independantly; it'll either fill with my textbox,
or the test string. but if the innerhtml is filled with the text box,
then i make a new selection that fills it with "test", it doesn't clear
out the text box.
Probably because of the duplicated ID attribute.

Presumably replacing the HTML with simple text removed the duplicate ID.

I looked, but it's messy. I think the above advice will do the trick.

that's it, that's rob! i'd been looking at the stooopid code all day
and it'd figure i'd miss something dumb like that!

yeah, it's all being dumped into the middle of a blog, so that doesn't
help... thanks for the hints though- it did the trick!
