无法为练习模板获取正确的语法

Question

我希望这不是太多的代码来查看我认为可能是一些语法错误。我遇到了很多不同类型的错误，并尝试将此代码编译，但最新的是 “在ms-appx：//io.cordova.myapp7523d86d4f8a4241bd8c3bad3d5fe0a3/www/scripts/index.js第33行第33行检测到严重错误.SETIPT1006：预期'）”，这是“setPlaceholderImage（）”行。

这是一个练习模板应用程序，可以在https://msdn.microsoft.com/en-us/magazine/dn879349.aspx找到：TITLED：跨平台：使用Apache Cordova在Visual Studio中编写跨平台混合应用程序。

(function () {
    "use strict";
    document.addEventListener('deviceready', onDeviceReady.bind(this),         false);

    function onDeviceReady() {

        // Perform other initialization here.
    };
    locate();
    document.getElementById("btnLocate").addEventListener("click", locate);

    (function locate() {
        navigator.geolocation.getCurrentPosition(function (position) {
            App.lastPosition = {
                latitude: position.coords.latitude, 
                longitude: position.coords.longitude,
                address: "(  position.coords.latitude  )" + "(  position.coords.longitude  )" };

            // Go translate the coordinates into an address using the Bing Map Web API.
            updatePosition();
        }, function (error) {
