getPageSize:function(){

接下来就是对话框的实现
$.extend({
alert:function(html,callback){
var dialog=new Dialog();
dialog.build(‘alert’,callback,html);
},
confirm:function(html,callback){
var dialog=new Dialog();
dialog.build(‘confirm’,callback,html);
}
});
调用方法：
$.confirm(‘确定删除？’,function(){
alert(‘cccc’);
});
div.alertParent{
padding:6px;
background:#ccc;
background:rgba(201,201,201,0.8);
width:auto;
position:absolute;
-moz-border-radius:3px;
font-size:12px;
top:50px;
left:50px;
}
div.alertContent{
background:#fff;
width:350px;
