jquery remove specific element from a specific id

I have 2 div li开发者_开发知识库ke this:

<div id="container1"><input class="1"><input class="2"></div>

<div id="container2"><input class="1"><input class="1"><input class="2"></div>

Now how do I remove all class="1" but only from the container2.

---

This should do it.

$('#container2 .1').remove();

This seeks all descendants from the element with id "container2" which belongs to the class named "1" and then remove them from the DOM.
