jquery provides ajax() that is more versatile than get and post

$.ajax(options)
$.ajax({
    type:"POST",                                               //方式
    url:"test.jsp",                                            //地址
    dataType:"JSON",                                           //数据类型  xml(xml文档),html(html代码),script(js代码),json(json数据),jsonp(jsonp格式数据),text(纯文本)
    beforeSend:function(XMLHttpRequest){                        //发送前函数, 这里可以修改XMLHttpRequest,例如添加HTTP头
    },
    complete:function(XMLHttpRequest,textStatus){               //请求完成函数,请求成功或失败均调用此函数
    },
    sucess:function(data,textStatus){                           //请求成功,成功返回,    //data有可能是xmlDoc,jsonObj,html,text等等
    },
    error:function(XMLHttpRequest,textStatus,errorThrown){      //请求失败函数
    },
    global:true                                                 //是否触发全局ajax事件,默认为true。全局函数开启,任何jquery类能调用后面的ajax全局函数});

Global ajax function

Any jquery object can call the global ajax function
The code is as follows:

$("#loading").ajaxStart(function(){});   //ajaxStart请求开,ajaxStop请求结束   ajaxComplete请求完成    ajaxError请求错误    ajaxSend发送请求前    ajaxSucess请求成功开,ajaxStop请求结束   ajaxComplete请求完成    ajaxError请求错误    ajaxSend发送请求前    ajaxSucess请求成功
