How to reset elements to their original state, after a chain of manipulations?
After a bunch of animating, adding classes and setting css styles. is there an easy way to reset an element to be back in its original server delivered stat开发者_高级运维e?
jQuery sets its manipulations using the inline style
attribute, so just set that to ''
.
$('#someDiv').attr('style','');
This assumes there were no inline style
attributes set on the element coming from the server. Better to use style sheets if so.
If the element must come from the server with style
attributes set, then I suppose you could cache the value in a variable, and reset it when needed.
// Cache original attributes
var originalAttributes = $('#someDiv').attr('style');
// Reset from original
$('#someDiv').attr('style',originalAttributes);
EDIT:
If needed, you could send your elements from the server with custom attributes to remember the original class
attribute, for example.
<div class="myClass" originalClass="myClass">...</div>
Then you can reference the original anytime you need.
You could even find all elements that have the originalClass
attribute like this.
var $elementsWithOriginal = $('[originalClass]');
or find elements where the class
attribute has been modified from the original.
var $modifiedFromOriginal = $('[originalClass]').filter(function() {
return $(this).attr('class') != $(this).attr('originalClass');
});
