The example in this article describes how to use the jQuery unbind() method. Share it with everyone for your reference, the details are as follows:
The unbind() method in jQuery is the reverse operation of the bind() method and removes the bound event from each matching element.
Grammar structure:
type is the event type, data is the event to be removed. The specific instructions are as follows:
1. If there are no parameters, delete all binding events;
2. If the event type (type) is provided as a parameter, only the bound events of this type will be deleted;
3. If the handler function passed during binding is used as the second parameter, only this specific event handler function will be deleted.
Please see the example below:
<script src="jquery.js" type="text/javascript"></script> <style> .info { background:#ffff66; } </style> <input type="button" id="btn" value="点击我" /> <input type="button" id="delAll" value="删除全部绑定函数" /> <input type="button" id="delFun2" value="删除第二个绑定函数" /><br /> <div class="info"></div> <script type="text/javascript"> $(document).ready(function(){ // 为id为btn的按钮添加绑定事件 $("#btn").bind('click', fun1=function(){ $(".info").append('<p>绑定函数1</p>'); }).bind('click', fun2=function(){ $(".info").append('<p>绑定函数2</p>'); }).bind('click', fun3=function(){ $(".info").append('<p>绑定函数3</p>'); }) $("#delAll").bind('click', function(){ $("#btn").unbind(); //删除全部绑定事件 }) $("#delFun2").bind('click', function(){ $("#btn").unbind('click', fun2); //删除第二个绑定函数 }) }) </script>
