Does anyone know, I have a div element when the first load I set its attributes to right:0
and bottom:0
; I want to get its style.left
but it return NaN
. So how to get it or is there another way?
<div id="myDiv">Sample</div>
<script type="text/javascript">
var setMe = document.getElementById("myDiv");
setMe.setAttribute("style", "background-color: red;
position: absolute;
width: 670px;
height: 370px;
right: 0;
bottom: 0;");
alert(setMe.style.left)
</script>
Try it using getComputedStyle() : ( Demo )
var setMe=document.getElementById("myDiv");
setMe.setAttribute("style", "background-color:red;position:absolute;width:670px;height:370px;right:0;bottom:0;");
alert(window.getComputedStyle(setMe).left);
Use offsetLeft attribute.
<html>
<head></head>
<body>
<div id="myDiv">Sample</div>
<script type="text/javascript">
var setMe=document.getElementById("myDiv");
setMe.setAttribute("style", "background-color:red;position:absolute;width:670px;height:370px;right:0;bottom:0;");
alert(setMe.offsetLeft);
</script>
</body>
</html>
you have three options:
style property // --> Returns an object that represents the element's style attribute (setted when parsed)
getAttribute // --> returns the value of the named attribute on the specified element.
computedStyle // --> gives the final used values of all the CSS properties of an element.
Take a look at this fiddle (demo) for an example in every one.
