Check for div's with a certain width

I have a bunch of div's that I have set to animate at the moment. However I am wanting a way that if they've been animated (Their width would have changed from 100px to 300px for example) they won't reanimate when I click on them again. I'm new to javascript & jquery so I'm unsure how to check开发者_运维技巧 the width of a div element to place in an if statement. If I need to post the code I can if requested. Thanks

Like this:

$('selector')
    .filter(function() { return $(this).width() < 300; })
    .animate(...);

You should add a class to all elements you want to animate

<div class="animateMe something something"> 
content
</div>

and in jQuery

$('div.animateMe').animate({animate params},duration,function(){
     $(this).removeClass('animateMe');
});

this will act as a flag and once animation has been done, it wont happen again on same element irrespective of height and width.

Advantage: Your code will not depend upon height/width params. if tomorrow animation changes and your blocks animate to a different height/width, this code will still be valid.

syntax for animate is jQuery.animate({animation params}, duration, callback);

Caution: Don't use the animateMe class for styling

You can use :

if($(".bunch-of-divs-class").width() == something)
{
     //Do Something
}
