HTML Question

get element padding value using javascript

I have a textarea in HTML. I need to get the padding value in pixel or float. Can I get it using JavaScript? I am not using jQuery, it's pure JavaScript.

Can somebody tell me how?

Answer

This will return the padding-left value:

window.getComputedStyle(txt, null).getPropertyValue('padding-left')

where txt is the reference to your TEXTAREA element.

The above works in all modern browsers and in IE9. However, it does not work in IE8 and below.

Btw, just for comparison, this is how you get the same job done using jQuery:

$(txt).css('padding-left')

The above does work in IE6-8.
