Question

I have a div

 <div id="chart" style="position:relative; width: 100%; float:left; height: 220px;">
</div>

And I need to change width dynamically. I found solution like:

var elem = document.getElementById('chart');

   elem.style.width = 70 + "%";

But that not work’s. Where I do wrong ? Thanks in advance…

Try this fiddle: http://jsfiddle.net/TrrCh/

I think you are trying to run the Javascript before the HTML is loaded. Bind it to the document.ready and it should be working

window.onload=function(){
    var elem = document.getElementById('chart');
    elem.style.width = 70 + "%";

}
