Try this: http://jsfiddle.net/5SRLE/1/
$("div").children().remove();
Of course, you'll want to target the specific div
with that selector (if you have other divs that you don't want to remove children from). If you have problems, show your context so we can make it more specific... or give your div an id like myDiv
and then use the selector $("#myDiv")
in place of $("div")
