注意：

.live() was introduced in jQuery 1.3, therefore it won't work with earlier versions.

.live() has also since been deprecated in jQuery 1.7 onwards.

The alternatives are .on() and .delegate()

See related question jQuery 1.9 .live() is not a function on how to migrate existing code.

代码中使用的是jquery 1.5 所以可以使用.live函数

用on绑定未来元素：

//放在$(function(){})里才有效 
$(document).on("click", "#testDiv", function(){ 
//此处的$(this)指$( "#testDiv")，而非$(document) 
}); 

绑定已有元素和未来元素

$(function(){
//动态添加
$(".add").on("click",function(){
console.log("进来了");
$(".info").append('<div class="delete"><h3>单击我来删除我</h3></div>');
});
 //对动态添加的元素添加事件-删除
$(".info").on("click",".delete",function(){
console.log("进来了Delete！");
$(this).remove();
});
 });
