Using "this" combined with other elements?

I use PHP and jQuery. I'm trying to do some开发者_StackOverflow社区thing like this:

$(this + ' .my_child_class').html('test');

I have a dynamic list of elements and when click on a button I use "this" to get to the current element group.

The problem is that I want to get to the class "my_child_class" which is somewhere within the current element group. The jQuery above don't work.

The HTML could look like this:

<div class="item">
   <div class="container">
      <div class="my_child_class">Content</div>
   </div>
   <input type="submit" />
</div>

<div class="item">
   <div class="container">
      <div class="my_child_class">Content</div>
   </div>
   <input type="submit" />
</div>

I'm assuming this is happening in an event handler -- this is a DOM element there, not a string. You probably want this:

$(this).find('.my_child_class').html('test');

You should put this code in your function:

$(document).ready(function() {

  $("div.item > input").bind('click',function() {

    $(this).prev().find('.my_child_class').html('test');

  });

});

You can find the whole solution here : http://jsfiddle.net/PLm5a/1/

Is this what you're after? Something like:

$(this).closest(".item").find(".my_child_class").html("test");

attached to the input button.

Without knowing what this actually refers to, I suspect you need

$(this).find(".my_child_class").html("test");

You may want to take a look at the other Traversing functions, too, depending on your situation.
