jquery ajax设置header的两种方式

一、setting参数 headers

$.ajax({    headers: {        Accept: "application/json; charset=utf-8"    },    type: "get",    success: function (data) {    }});

二、beforeSend方法

$("#test").click(function() {                $.ajax({                    type: "GET",                    url: "default.aspx",                    beforeSend: function(request) {                        request.setRequestHeader("Test", "Chenxizhang");                    },                    success: function(result) {                        alert(result);                    }                });            });
