jQuery height() problem

How do we go about accessing a height for a Gridview? The Gridview has a CSS attribute called height that is set to 800px, but I haven't been able to acces开发者_如何学JAVAs anything with height()

$('ctl00_MainContent_grdPersonResults').height() = null

Any ideas?

When you want to get an element by id you need to prepend a pound sign/hash to use the id selector.

$('#ctl00_MainContent_grdPersonResults').height()...

without it, it will be selecting based on elements having the string as a class name. I'm sure that none of your controls would have that as a class name so the selector is failing. Note that because of the ASP.NET mangles names, though, it may be easier to assign a class name and use the class name selector.

try:

$('ctl00_MainContent_grdPersonResults').innerHeight();
