需要有关ajax的帮助

so I have created a link and am using jquery and ajax to load a new web page using this link, now is there anyway where I can change some content on this dynamically loaded page?
For example, the new page has a drop-down list, so can I somehow set the value of this drop-down list.

I tried to using the following in the load function

$('#content').load("inq.html #content",function(){
('selectid').val('optionvalue'); 
});

The selectid and optionvalue are in the loaded page.
This did not work.

It should work. In your example you forgot the jQuery object and didn't have the correct selector in the callback:

$('#content').load("inq.html #content",function(){
    $('#selectid').val('optionvalue'); 
});

your url appears to be malformed. something like "/inq.html#html"
