我已阅读并关注本网站或网站上有关如何使用Jquery Mobile将NativeControls插件添加到PhoneGap（Cordova 1.5）的教程。我无法让工具栏正常工作。
我尝试了许多不同的事情而没有运气。这是我的代码：

<body onload="onBodyLoad()">

</html>
main.js：
function onBodyLoad()
{
$('#submit').click(function() {
var program = document.getElementById('program').value;
var username = document.getElementById('username').value;
var password = document.getElementById('password').value;
if (!program || program == "") {
alert("Please enter a program");
return false;
}
else if (!username || username == "") {
alert("Please enter a username");
return false;
}
else if (!password || password == "") {
alert("Please enter a password");
return false;
}
return true;
});
document.addEventListener("deviceready", onDeviceReady, false);
}
/* When this function is called, Cordova has been initialized and is ready to roll */
/* If you are supporting your own protocol, the var invokeString will contain any arguments to the app launch.

function onDeviceReady() {
// Initializating TabBar
navigator.notification.alert("Cordova is working");
nativeControls = window.plugins.nativeControls;
navigator.notification.alert(nativeControls);
nativeControls.createTabBar();
// Books tab
nativeControls.createTabBarItem(
"books",
"Books",
//"/www/tabs/book.png",
"",
{"onSelect": function() {
books();
}}
);
// Stats tab
nativeControls.createTabBarItem(
"finished",
"Finished",
//"/www/tabs/box.png",
"",
{"onSelect": function() {
finished();
}}
);
// About tab
nativeControls.createTabBarItem(
"about",
"About",
//"/www/tabs/info.png",
"",
{"onSelect": function() {
about();
}}
);
// Compile the TabBar
nativeControls.showTabBar();
nativeControls.showTabBarItems("books", "finished", "about");
nativeControls.selectTabBarItem("books");
}
function books() {
}
function about() {
}
function finished(){
}
如你所见，我做了一个：
navigator.notification.alert("Cordova is working");
nativeControls = window.plugins.nativeControls;
navigator.notification.alert(nativeControls);
nativeControls.createTabBar();
测试nativeControls变量是否包含任何内容。我没有得到任何警报。 我甚至尝试过：
navigator.notification.alert(window);
非常感谢任何帮助！

我将源代码上传到iTunes商店的jQM应用程序，该应用程序在两个方向上都有一个Tabbar工作在iPhone和iPad上的示例。我希望它有所帮助!!

我也遭受了同样的挣扎。构造函数可能存在一些误解。
我看到了a post，其中添加了额外的几行以避免任何冲突，并且它有效！
答案 2 :(得分：4)
这是我的代码，它有效：
function onDeviceReady()
{
var nc = window.plugins.nativeControls;
nc.createTabBar();
nc.createTabBarItem('whoTabItem', 'Quem?', '', null);
nc.createTabBarItem('whereTabItem', 'Onde?', '', null);
nc.createTabBarItem('whatTabItem', 'O que?', '', null);
nc.showTabBar();
nc.showTabBarItems('whoTabItem', 'whereTabItem', 'whatTabItem');
}
在NativeControls.js的最后，window.plugins.nativeControls被初始化，所以应该没问题：
if(!window.plugins)
window.plugins = {};
window.plugins.nativeControls = new NativeControls();
您对createTabBarItem的调用有5个参数 - 它只有4个。消除第四个空白参数并进行测试。也许这就是你的onSelect功能不起作用的原因。
答案 3 :(得分：0)
您需要在main.js文件的顶部将 nativeControls 定义为变量，然后您可以在此行中使用它，否则，js将通过关于未定义变量的异常
nativeControls = window.plugins.nativeControls;
