jquery get styles from an id
does anyone know how can i get all styles applied to an id using jquery (so i can reuse it late开发者_运维百科r in another tag)? something like css:
div#myid{
width:100px;
height:100px;}
so i can later do something like:
for (var parts in $('#myid').css())
alert ('all parts of the style' + parts);
$('#myid').attr('class') returns a string of the classes.
You should be able to figure it out from here.
var classes = $('#myid').attr('class').split(' ');
for(var c in classes)
{
alert(classes[c]);
}
It is not jquery but works well:
var style = window.getComputedStyle(document.getElementById('myid'), null);
alert(style.color);
You can replace document.getElementById('myid') by $('#myid').get(0) if you really want to use jquery here.
This works either for a style given by CSS or directly applied on the element with the style attribute.
Not sure.. I had tried attr('class') before and it returned empty. trying now again produces the same result (nearly). i suppose attr('class') in jquery isnt exactly the same as styles defined via id. try running this, let me know if you get different results please:
<html>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.4.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function (){
alert($('#myid').attr('class')); // returns 'empty'
var classes = $('#myid').attr('class').split(' ');
for(var c in classes){
alert(c); // returns 0
}
});
</script>
<style>
#myid {
width:100px;
height:100px;
background:red;
}
</style>
<body>
<div id="myid"></div>
</body>
</html>
