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);  
                    }  
                });  
            });
