Question

i have this line of code :

document.getElementById(object).innerHTML=data;

where object is equal to 'index' (which is an id for a div in the html) and data is some text … no errors on firefox or chrome , but internet explorer gives me “Unknown runtime error” !!! i’ll become bald soon …

Data Sample : (for some reason , if i remove the <table> everything goes just fine …)

<table style="width:100%;">
                <tr class="tablePagnation">
            <td valign=top colspan="5">
                <input type=hidden id="pagnation" value="1">

Answer 1

I ran into a similar issue a few weeks ago. You get an “Unknown runtime error” when you insert malformed HTML into the document. IE is not as forgiving, apparently.

Sometimes, you will also get this error if you try to insert a block-level element inside an inline element (for example, a div inside a p will cause this error). You can get around this by changing the parent element. Can you tell us into what kind of element you’re trying to insert data?

Here is a blog post that talks about the error and a stackoverflow question that deals with the error in the context of manipulating tables via Javascript.

UPDATE

In this case, I guess you’ll have to figure out what the offending element is by trimming the scope. Try inserting the simplest possible HTML (perhaps your table with just a single row and cell). Then progressively add more elements until you get the error. That way, you will be able to identify the element that is causing the error.
