Unable to get value of margin property from result getComputedStyle

Question

The result of a getComputedStyle contains a property named \"margin\", but the property is always an empty string (\"\") in Mozilla Firefox or Appl

Answer 1

I tried something like this and it is worKing for me in all browsers

var elem = document.createElement('div');

var t=document.createTextNode('M')
elem.appendChild(t);
document.body.appendChild(elem);

var myfontSize = getStyle(elem,"fontSize")
alert(myfontSize)

function getStyle(elem,prop){
if (elem.currentStyle) {
var res= elem.currentStyle.margin;
} else if (window.getComputedStyle) {
if (window.getComputedStyle.getPropertyValue){
var res= window.getComputedStyle(elem, null).getPropertyValue(prop)}
else{var res =window.getComputedStyle(elem)[prop] };
}
return res;
}
