Get styles of a CSS class

Question

See more:

I need to get the style of an element and write it out. The problem is, the styles are given though multiple classes. Is there a way for me to see exactly what styles are influencing an element?

EDIT: Ok, I think the question is pretty self explanatory, but here:

<div id="myDiv" class="divClass">
<label class="labelClass">Hello World</label>
</div>

Lets say that the divClass has "width:250px", and the labelClass has "color:#e3e3e3". I need to get those styles through a JavaScript function.

I have Googled and found that exact page. The problem with that method is I will have to loop through every possible CSS attribute and see if it is applied.

Thanks, but I am getting an "obj.style is undefined" error.

Lets check the source of your code. What is the name of your myDiv. And then use that Id from source code.

Solution 4

document.getElementById('myDiv').className

This will return you the applied class on the control.
