Bind jQuery hover event to multiple DOM elements

I've an unordered list of elements and I want to bind hover event to each of these elements. The HTML structure is as follows :

<ul>
  <li id="url_1">item 1</li>
  <li id="url_2">item 2</li>
</ul>

I figured using a for-loop would be the best way to do it. So my jQuery code is as follows:

for(i=1;i<=2;i++){
   $("li#url_"+i).hover(function () { /* do something on mouseenter */}, function () { /* do something on mouseleave */ }); }

This should bind the hover event to li#url_1 & li#url_2. But it is not working!

Can you please suggest the right开发者_JAVA百科 (and more efficient) way to do this?

first, don't forget to put your jQuery code inside a $(document).ready(function { }) block, so it would perform only the DOM is loaded.

Second, why not assign an ID, or class, or whatever what will help you access that UL element in the top, and then do this:

$("ul#yourId > li").hover(function() { ............. }, function() { ...   });

instead of building a cycle. Inside the event handlers, use this to access the li element, and see its id if needed. The event handlers will be assigned to all the li elements which are direct children of that ul element with yourid as the id, for example.
