innerHTML

Hi all,

Just a little one this but when I write this:

P4.innerHTML =""

I get an unknown runtime error! P4 refers to this in my HTML:



I need a horizontal line to appear there. Any ideas?

What is the error?

Try document.getElementById('P4').innerHTML = '';

Is this line run before the element exists?

HTH,

Yes the line is run before the element exists, as I'm trying to use it to create the . Its a Set rather than a Get.

LOL.... Running the line before the element exists is not good.

Try placing your line in an onload function:

onload=function(){document.getElementById('P4').in nerHTML=""};

But, if you want to put it in there when the page loads, why don't you just directly add it?



HTH,

LOL I agree but in this case I need to make an exception as I need the to appear onmouseover? Oh btw the error reads thusly: Unknown Runtime Error.

What browser are you using?

This should work....

Code:

<script type='text/javascript' language='javascript'>
var p1 = document.getElementById('para1');
function showHR()
{
 p1.innerHTML = '';
}
function hideHR()
{
 p1.innerHTML = '';
}
</script>
<button onmouseover='showHR()' onmouseout='hideHR()'>click</button>
<p id='para1'></p>

HTH,

Snib

IE will not let you use certain tags in an innerHTML expression within tags, e.g., , <h2 />, etc.

If you change your tag to a everything should work.

Even Snib's code should work then! :)
