How to check a checkbox jquery

Question

I am trying to use jquery to check my checkbox:

<div class="checkbox">
  <label><input type="checkbox" value="" id="restricted_access">Restricted Access?</label>
</div>

My js:

$('#restricted_access').prop('checked', true);

But this just returns

[<input type=​"checkbox" value id=​"restricted_access" checked=​"checked">​]

Can someone help?

Here's my fiddle:

Answer 1

用这个：

$('#restricted_access').prop('checked', true);

Answer 2

The pure JavaScript way:

 document.getElementById('restricted_access').checked = true; 

 <div class="checkbox"> <label> <input type="checkbox" value="" id="restricted_access">Restricted Access?</label> </div>
