.bind()是最直接的绑定方法 ,会绑定事件类型和处理函数到DOM element上, 这个方法是存在最久的,而且也很好的解决了浏览器在事件处理中的兼容问题。但是这个方法有一些performance方面的问题,看下面的代码: /* The .bind() method attaches the event handler directly to the DOM element in question ( "#members...

$(document).ready(function() { //关于on,bind,delegate的区别。 //1.选择器匹配到的元素比较多时,不要用bind()迭代绑定 //2.用id选择器时,可以用bind() //3.需要给动态添加的元素绑定时,用delegate()或者on() //4.用delegate()和on()方法,dom树不要太深 ...
(先决条件,绑定的dom element必须已经存在) --- As of jQuery 1.7, the .on() method is the preferred method for attaching event handlers to a document. 手册上有相关用法例子 $("a.offsite").live("click", function(){ alert("Goodbye!"); }); $(document).on("click", "a.offsite", func...

在JavaScript中通过查找DOM对象,对其绑定。 var v=document.getElementById("button"); v.onclick=function clickHandler(event){ alert(event.type); } 1. 2. 3. 4. 5. 6. 也就是elementObject.onclick=function(){} 的格式。 三、绑定事件...
.keyup(): Bind an event handler to the "keyup" JavaScript event, or trigger that event on an element. 除了封装大多数的javascript事件,jQuery提供了统一的事件绑定和触发机制: 绑定事件:bind、on、live、delegate、keyup(<function>); 触发事件:trigger('keyup')、keyup(); 解绑事件:unbind、off、die...
