Is there a way to retrieve all styles applied to an ID using jQuery in order to reuse them later on another tag? For example, like this CSS:
div#myid{
width:100px;
height:100px;}
So that I can later use something like:
for (var parts in $('#myid').css())
alert ('all parts of the style' + parts);
When using $('#myid').attr('class'), you will receive a string containing all the classes associated with that element.
Take some time to analyze this code snippet and see if you can understand what it does.
var classes = $('#myid').attr('class').split(' ');
for(var c in classes)
{
console.log(classes[c]);
}
Although it's not jquery, it functions effectively:
var style = window.getComputedStyle(document.getElementById('myid'), null);
alert(style.color);
If you prefer to use jquery, you can substitute document.getElementById('myid') with $('#myid').get(0).
This method is suitable for styles defined in CSS or directly applied to the element using the style attribute.
It seems there is some confusion with using the attr('class') method in jQuery. I remember trying it before and getting an empty result as well. After attempting it again, it still did not provide the expected outcome. It appears that the attr('class') function in jQuery does not behave the same way as styling done through an id selector. To clarify this further, could you please test the following code and let me know if you observe any differences:
<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')); // should return 'empty'
var classes = $('#myid').attr('class').split(' ');
for(var c in classes){
alert(c); // should return index of each class
}
});
</script>
<style>
#myid {
width:100px;
height:100px;
background:red;
}
</style>
<body>
<div id="myid"></div>
</body>
</html>
