How to find element with attribute?

Question

I have the following html:

<div class="item" data-value="100">Something</div>

Now, I am using the following to find this element:

$( "div[data-value=value]") 

Where value is "100". However, I don't think jquery sees the value as javascript object - I think it takes it as it is. How can I fix this?

Answer 1

Using filter

var $item = $('.item').filter(function(){
   return $(this).data('value') == 100;
});

Answer 2

$( "div[data-value=" + value + "]") 

Answer 3

Use concatenation

var value = 100;
$( "div[data-value='"+value+"']");
