在ASP.NET MVC 4中选择自动完成文本字段值时，如何进行另一个Ajax调用？

您可以

select

$(function () {    var src = '@Url.Action("GetParts", "Parts")'    $("#autoCompleteBox").autocomplete({        source: function (request, response) { $.ajax({     url: src,     async: true,     dataType: "json",     data: {         partNumber: $("#autoCompleteBox").val()     },     success: function (data) {         response(data[0]);     } });        },        select: function (event, ui) {var item= ui.item.label;//Now make the ajax call here$.post("SomevalidUrl", new { id : item } ,function(res){    // do something with res});        }    });});
