JS Get inline style

// get inline style    function getcss (obj,attr) {//obj: Object, Name:style property        if(obj.currentstyle ) {            return  obj.currentstyle[attr];        }         Else {            return document.defaultView.getComputedStyle (obj,null) [attr];        }    } 

As we all know, with document.getElementById (' element '). Style.xxx can get style information for an element, but it gets only the style rules in the DOM element style property, and the external style sheet referenced by the class attribute will not get the information we want.

The DOM standard has a global method getComputedStyle, which can get the current object style rule information, such as: getComputedStyle (obj,null). paddingleft

But it's not over, the evil IE does not support this method, it has its own implementation, that is, currentstyle, unlike the global method getComputedStyle, which is a DOM element attribute exists, such as: Obj.currentStyle.paddingLeft, in IE gets the object's left inner margin
