How to call CSS from JavaScript

Question

I want to have different background images for different conditions (JS,HTML,CSS). For E.g: if(n=1),then image 1 else if(n=2),then image 2 etc.

Answer 1

Try creating a Css class ..After that you can set it to your control from javascript..

document.getElementById("MyControl").className = "MyClass";

In the css class MyClass you can set the background image..You can create another css class with different background image and set it according to the conditions..
