jQuery ajax http状态代码

试试这个：

request = $.ajax({    type: "GET",    url: url,    data: data,    statusCode: {      200: function() {        doSomething();       },      304:function(){        doSomethingElse();       }     }});

要么：

request = $.ajax({    type: "GET",    url: url,    data: data,    complete: function(e, xhr, settings){       if(e.status === 200){       }else if(e.status === 304){       }else{       }    }});
