解析ajax事件的调用顺序

jquery的ajax请求方法：

$.ajax({
            type: "get",
                datetype:"html",
                url: "index.html",
                error: function(msg) { alert("error"); },
                complete: function(msg) { alert("complete"); },
                success: function(msg) { alert("success"); }             

            });

jquery中各个事件执行顺序如下：
1.ajaxstart(全局事件)
2.beforesend
3.ajaxsend(全局事件)
4.success
5.ajaxsuccess(全局事件)
6.error
7.ajaxerror (全局事件)
8.complete
9.ajaxcomplete(全局事件)
10.ajaxstop(全局事件)
