[jQuery] Re: Why isn't there top() and left() methods in the dimension plugin ?

[Brandon Aaron]

You can very easily add these helper methods to your own app like this:

jQuery.fn.left = function() {
return this.offset({scroll:false}).left;
};

jQuery.fn.top = function() {
return this.offset({scroll:false}).top;
};

 I'm annoyed with the (otherwise great) dimension plugin because there is
 no direct way to get the top
 and left position of an element.
 So all over my code I have things such as :

   $errorBoxOffset = {};
   element.offset({scroll: false}, $errorBoxOffset);
   $left = $errorBoxOffset.left;
   $top = $errorBoxOffset.top;


 Have I missed something in the dimension doc ?
 Do you think it would make sense to add such functions to the dimensions
 plugin ?

Hi Olivier,

The Dimensions plugin has a very powerful .offset() method. Perhaps  
that is what you're looking for?


For a demo of Dimemsions methods, check out this companion page to  
the Dimensions chapter in jQuery Reference Guide:

Wow your too fast guys.
It seems that I was using offset() the wrong way.

  $left = element.offset().left;
  $top = element.offset().top;

is fine for me in replacement of :

  $errorBoxOffset = {};
  element.offset({scroll: false}, $errorBoxOffset);
  $left = $errorBoxOffset.left;
  $top = $errorBoxOffset.top;

Thanks a lot guys!

The only problem with that is you are calling offset twice (which may
impact performance). I would do:

$offset = element.offset();
$left = $offset.left; $top = $offset.top;
