Question

我有两个不同的功能，即onLogin: function(){}和addvehicleDetails: function(){}

在onLogin函数中，我通过ajax返回调用获取数据，我将分配变量returnText，然后returnText我正在使用addvehicleDetails函数。

但是根据控制台，当我来addvehicleDetails()功能时，我得到了不确定。

我想要实现的是我想访问一个相同的变量，该变量由两个不同的函数全局声明使用，其中一个获取值而另一个使用它。

//Global variable
var returnText = new Array();

代码如下

//Login
        onLogin: function(){
            debugger;
            var that = this,
            username = that.get("username").trim(),
            password = that.get("password").trim();
            if (username === "" || password === "") {
                navigator.notification.alert("Both fields are required!",
                                             function () {
                                             }, "Login failed", 'OK');


                return;
            }

            var request = $.ajax({
                  url: "http://localhost:62373/api/Vehicle/Login",
                  type: "GET",
                  data: {strUsername: username, strPassword: password},
                  dataType: "text"
                });

                request.done(function(data, textStatus, jqXHR) {


                   alert("Success: " + data);
                    returnText[0] = data;
                    alert(returnText[0]);
                    debugger;
                    window.location.href = "iVehicle.html"


               });

        },


 //add vehicle details
        addvehicleDetails: function(){
            debugger;
            var that = this;
            vehicleName = that.get("vehicleName").trim(),
            vehicleType = that.get("vehicleType").trim(),
            registrationNumber = that.get("registrationNumber").trim(),
            fuelType = that.get("fuelType").trim(),
            fuelEfficiency = that.get("fuelEfficiency").trim(),
            insuranceBy = that.get("insuranceBy").trim(),


            dateCreated = new Date();
            var month = dateCreated.getMonth()+1;
            var day = dateCreated.getDate();
            var output = dateCreated.getFullYear() + '/' +
            (month<10 ? '0' : '') + month + '/' +
            (day<10 ? '0' : '') + day;
            myGuid =  returnText[0];
            //myGuid = document.getElementById("hdn").value;
            alert(myGuid);
            var request = $.ajax({
                  url: "myurl",
                  type: "GET",
                  data: {vname:vehicleName, vtype:vehicleType, regNumber:registrationNumber, ftype:fuelType, fefficiency:fuelEfficiency, insby:insuranceBy, datecreated:output, myid:myGuid},
                  dataType: "text"
                });

                request.done(function(data, textStatus, jqXHR) {
                    alert("Success: " + data + ' ' + ".");
                    that.clearForm();
               });


                 request.fail(function( jqXHR, textStatus, errorThrown ) {
                alert("Request failed:" + errorThrown + ' ' + textStatus);
                  // that.clearForm();

                });


                request.always(function(jqXHR, textStatus, errorThrown) {
                // alert("complete: " + errorThrown + ' ' + textStatus);
                      that.clearForm();
                 });

        },

尝试这样的事情

    function onLogin{
        // your ajax code goes here
        // after successfull completion of ajax call your  addvehicleDetails function
        var response = //response from ajax
        addvehicleDetails(response);
    }

在javascript中从两个不同的函数访问全局变量
