Find html element which id starts with

Give that element a common class name or some other attribute you can query for.

Use the "attribute starts with" selector http://api.jquery.com/attribute-starts-with-selector/

$("[id^=list_]")

Be aware that this is inefficient. Prefix with the tag name and descend from the nearest parent if possible.

You need to use the attribute starts with selector, like this:

$('[id^=list_]').whatever()

Try

$('div[id^="list_"]')

It should work
