To achieve the effect: Click on the link to remove the onclick attribute, after 3 seconds and then automatically add the onclick attribute in the tag
In jquery, the actions for tag attributes are implemented using the attr () method, such as $ ("a"). attr ("onclick") can get the OnClick property of the A tag, corresponding to:
Add Event:
$ (selector). attr (property name) The function of this is to get the value of the specified property of the specified element (the selector part)
Such as
To set the OnClick property:
$ ("a"). attr ("onclick", "Test ();");
To delete an event:
$ (selector). Removeattr (attribute)
Cases:
Delete the OnClick property:
$ ("a"). Removeattr ("onclick");
Theoretically the above code is not a problem, but in fact the above statement does not execute or error, and later found the reason:
The previous version of JQuery 1.6 does not support the attr () method in relation to the tag onclick property!
In other words, the onclick attribute in the action label using the attr () method must use the JQ library 1.6 or the updated library version!
The code is as follows:
<Scripttype= "Text/javascript"src= "Jquery.min.js"></Script><Scripttype= "Text/javascript">$(function(){ $(". b"). Click (function(){ $( This). Removeattr ("onclick"); SetTimeout (function(){ $(". b"). attr ("onclick","test ();"); }, the) }) })functionTest () {}</Script><P> <aclass= "B"href="#"onclick= "Test ();">Click to remove the OnClick property of the link, and then automatically add the OnClick property after 3 seconds</a></P>
The key word for deleting attributes in jquery is: removeattr Note A is uppercase
