javascript - How to dynamically change CSS style attribute of DIV tag? -

-

we have div tag: <div id='div1' style="background-color:red"></div>

i know how can change style attribute of div tag:-

  1. can clear style value?

  2. can append value existing style attribute ?

  3. can set new value style attribute

thanks in advance.

var div = document.getelementbyid('div1');  // clear value div.setattribute('style','');   // or div.removeattribute('style');  // set style / append style div.style.backgroundcolor = '#ff0000';

don't modify style attribute directly when adding or changing styles unless want remove them all.
