Two ways to set header in jquery ajax

1. Setting parameter headers

$.ajax({

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

});

Second, beforeSend method

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