jQuery Question

Get css top value as number not as string?

In jQuery you can get the top position relative to the parent as a number, but you can not get the css top value as a number if it was set in


Say I have the following:


Bla text bla this takes op vertical space....
<div id='elem'>bla</div>

$('#elem').position().top; //Returns the number (10+(the vertical space took by the text))
$('#elem').css('top'); //Returns the string '10px'

But I want to have the css top property as the number

How would one achieve this?

You can use the parseInt() function to convert the string to a number, e.g:


Update: (as suggested by Ben): You should give the radix too:

parseInt($('#elem').css('top'), 10);

Forces it to be parsed as a decimal number, otherwise strings beginning with '0' might be parsed as an octal number (might depend on the browser used).
