[jQuery] prob with the jquery selector

hello everyone,
   maybe this problem is not a new one,but i
want to make sure.when i use $('#'+id) to choose an element in the dom
tree to operate on,it failed when the id is in the form of
abc[xyz].code like below:
html code:
 <input id='abc[xyz]' value='just a test' />
js:
temp = $('#'+'abc[xyz]').val();
it failed.
