如何在 Jquery 中导出 Excel？

Question

I'm new to Jquery so what i want is when i click on button Excel Sheet is downloaded through sql query, I want code only in jquery so suggest me some piece of code or idea how to do that.

这是 my.js 文件

function Contract_Export_Excel() {
try {
    var dataString = {};

   ShowLoader();
    AjaxSubmission(dataString, '/Contract/ExportExcel', $('input[name=__RequestVerificationToken]').val()).done(function (result) {
        if (result.Message == 'success') {
            if (result.Data.Table != undefined && result.Data.Table.length != 0) {
                if (result.Data.Table[0].CurrentState == 'success') {

                    var item = result.Data.Table[0];

                            debugger;
                            var bytes = new Uint8Array(item.FileContents);
                            var blob = new Blob(bytes, { type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" });
                            var link = document.createElement('a');
                            link.href = window.URL.createObjectURL(blob);
                            link.download = "myFileName1.xls";
                            link.click();


                }
                else {...}

i think this above code is not correct suggest me some code under ajax call and im only call the controller for database access and nothing to do in controller so suggest me some code to export excel.

这是我的 Controller

[HttpPost, SessionAuthorization, ValidateAntiForgeryHeader]
    public string ExportExcel(string formData)
    {
        try
        {
            formData = HttpUtility.HtmlDecode(formData);
            ContractAC component = new ContractAC();
            DataSet dataset = new DataSet();
            ContractMapper mapper = JsonConvert.DeserializeObject<ContractMapper>(formData);

            UserSession userSession = (UserSession)Session["userSession"];
            mapper.Company_Id = userSession.Company_Id;
            mapper.Branch_Id = userSession.Branch_Id;
            mapper.FY_Id = userSession.Financial_Year_Id;
            mapper.User_Id = userSession.User_Id;

            dataset = component.ExportExcelAC(mapper);




            return "{\"Status\":true , \"Message\":\"success\" ,\"Data\": " + JsonConvert.SerializeObject(dataset) + "}";
        }
        catch (Exception ex)
        {
            Logging.LogManager.Error("Error Details:- Controller: ContractController, Action: Get_Contracts_List, Type: Post, Error:" + ex);
            return "{\"Status\":true, \"Message\":\"" + ex.Message + "\"}";
        }
    }

function Contract_Export_Excel() {
try {
    var dataString = {};

   ShowLoader();
    AjaxSubmission(dataString, '/Contract/ExportExcel', $('input[name=__RequestVerificationToken]').val()).done(function (result) {
        if (result.Message == 'success') {
            if (result.Data.Table != undefined && result.Data.Table.length != 0) {
                if (result.Data.Table[0].CurrentState == 'success') {

                   // var item = Bind_Items(result.Data.Table1);



                    //debugger;
                           //var bytes = new Uint8Array(Bind_Items(result.Data.Table[1]));
                          /* var blob = new Blob(bytes , { type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" });
                            var link = document.createElement('a');
                            link.href = window.URL.createObjectURL(blob);
                            link.download = "myFileName1.xls";
                            link.click(); */
                    var table = $("<table/>").addClass('CSSTableGenerator');

                    $.each(result.Data.Table1, function (rowIndex, r) {
                        var row = $("<tr/>");
                        $.each(r, function (colIndex, c) {

                            row.append($("<t" + (rowIndex == 0 ? "h" : "d") + "/>").text(c));

                        });
                        table.append(row);
                    });
                   // var items = $(document.body).append(table);

                    // var bytes = new Uint8Array(items);
                    var blob = new Blob($(document.body).append(table), { type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" });
                     var link = document.createElement('a');
                     link.href = window.URL.createObjectURL(blob);
                     link.download = "myFileName1.xls";
                     link.click();


                }
                else {...
                }

我正在使用 CSSTableGenerator 和迭代，但在 excel 中我不会得到预期的结果，或者我没有在 excel 文件中得到我想要的表格，请帮助我......提前致谢！
