get Margins from a div javascript

问题

I need to change the margins of a div through javascript. But there is no such way as:

document.getElementById('div').style.margin-top = var;

Is there a way to do this? I can't find it anywhere

回答1:

use marginTop, not margin-top

document.getElementById('AnIdNotADiv').style.marginTop = value + "px";

回答2:

jQuery has the functionality you're looking for, it can manipulate elements that don't have IDs. Once the jQuery Library is included, the syntax for what you want would be:

$('div').css('margin-top',var);

For information about including jQuery, visit the jQuery API site: http://docs.jquery.com/Tutorials:Getting_Started_with_jQuery#Setup
