jQuery的AJAX HTTP状态code [英] jquery ajax http status code

问题描述

我改变我的脚本的jQuery的时刻。这是我的旧的javascript：

I am changing my scripts to jquery at the moment. This is my old javascript:

var request = (window.XMLHttpRequest) ? new XMLHttpRequest() : (window.ActiveXObject ? new window.ActiveXObject("Microsoft.XMLHTTP") : false);
request.open("GET", url, true);
request.onreadystatechange = updatePage;
request.send(null);

function updatePage() {
        if (request.readyState == 4) {
                if (request.status == 200) {
                    var response = request.responseText;
                    doSomething();
                } else if (request.status == 304) {
                    doSomethingElse();
                } else {
                }
        }
}

我现在想改变这个jQuery的阿贾克斯：

I now want to change this to jquery-ajax:

request = $.ajax({
    type: "GET",
    url: url,
    data: data,
    success: updatePage
});

我怎么可以测试状态code（以及responseText的）请求返回，就像我在我的旧脚本做？

How can I test for the status code (and the responseText) returned by the request, like I did in my old script?

推荐答案

试试这个：

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

或

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

       }else if(e.status === 304){

       }else{

       }
    }
});
