如何确定宽度是否有px或％

How can i tell if a css property such as width ex: width:100% has px or % assigned to it. in chrome for example if i have width:250px; and i do $('div').width() i get 250 whereas if i use percentage, i just get the width in px for the percentage based on my screen resolution.

    This should work.

    var value = $('#id').get(0).style.width;
var hasPx = value.indexOf('px') >= 0;
var hasPct = value.indexOf('%') >= 0;
