Clearing insertAdjacentHTML() ?

[kosmokramer]

Hey. I am making a rollover for one of my webpages which will take as arguments the image name, the width to make the image, and a description. When the link is rolled over, it will display in one cell of a table the picture and below it in another cell, the description.

function changeImage(theImage,newWidth,description)
{
    theImageObject = document.all('imagePlaceHolder');
	theImageObject.src=theImage;
	theImageObject.width=newWidth;
	descriptionHolder = document.all('theDescription');
	descriptionHolder.insertAdjacentHTML('BeforeEnd', description);
}

The problem is that the text is not replaced by the new text, it is simply appended on the end of the first text. Also, and this is a minor problem, but since insertAdjacentHTML() is an IE only function, how do I make it compatable with Netscape?

Well, since document.all is IE only as well, perhaps try rewriting it like so:

function changeImage(theImage,newWidth,description)
{
    theImageObject = document.getElementById('imagePlaceHolder');
    theImageObject.src=theImage;
    theImageObject.width=newWidth;
    descriptionHolder = document.getElementById('theDescription');
    descriptionHolder.innerText = description;
}

Hey. Thanks for the quick response! Got it to work!!

...uuh one more problem. I am passing the description as a string and it is printing out exactly what I put in...in other words if I put in: Go to<a href='someSite.html'> this site </a> it will print out Go to<a href='someSite.html'> this site </a> instead of Go to this site (with this site being underlined). I figure I will have to parse the string or something, but even when I isolate the html tag, I am not sure how to tell it that the text is not a string to just be printed out, but rather a hyperlink

[tt]descriptionHolder.innerText = description;[/tt]
[tt]descriptionHolder.innerHTML = description;[/tt]

Should do the trick for you... no string parsing needed.

Alright...It works! Thanks again
