如何从外部js访问变量

Question

我有外部javascript文件。我的要求是在视图上访问外部JS变量。在这里，我附上了我的Js来源，

var tdDetailList = [];
dateFormat: "mm/dd/yyyy",

(function ($) {


    $.extend($.ui, { multiDatesPicker: { version: "1.6.4"} });


    $.fn.multiDatesPicker = function(method) {
        var mdp_arguments = arguments;
        var ret = this;
        var today_date = new Date();
        var day_zero = new Date(0);
        var mdp_events = {};


        function removeDate(date, type) {
            if(!type) type = 'picked';

            date = dateConvert.call(this, date);
            for (var i = 0; i < this.multiDatesPicker.dates[type].length; i++)

                if (!methods.compareDates(this.multiDatesPicker.dates[type][i], date))
                {
                     this.multiDatesPicker.dates[type].splice(i, 1).pop();
                     window.tdDetailList.splice(i, 1).pop();
                }
                    return this.multiDatesPicker.dates[type].sort(methods.compareDates);
        }
        function removeIndex(index, type) {
            if(!type) type = 'picked';
            return this.multiDatesPicker.dates[type].splice(index, 1).pop();
        }
        function addDate(date, type, no_sort) {
            if (!type) type = 'picked';

            date = dateConvert.call(this, date);

            // @todo: use jQuery UI datepicker method instead
            date.setHours(0);
            date.setMinutes(0);
            date.setSeconds(0);
            date.setMilliseconds(0);

            var a = date.toLocaleDateString("en-US");


            if (methods.gotDate.call(this, date, type) === false) {
                this.multiDatesPicker.dates[type].push(date);
                window.tdDetailList.push(date.toLocaleDateString("en-US"));
                if (!no_sort) this.multiDatesPicker.dates[type].sort(methods.compareDates);             
            } 
        }

我的Html有脚本

 $('#Save').click(function () {
        var x = document.getElementById("roomId").value;
        if (x == '') {
            alert("Please select room Id");
        }
        else
        {
            var url = "/Home/SaveToDatabase";

            $.post(url, { "unabailableList.UnavailableDates": window.tdDetailList, "unabailableList.RoomID": x }, function (data) {
                alert(data);
            });
        }

})

此脚本在IE上正常运行但在Chrome上无法运行。在chrome中有一条错误消息＆＃34; tdDetailList＆＃34;未定义。请帮我解决这个问题。我想在视图

上从外部JS访问变量
