我正在尝试遵循 Aaron Saunders 的“使用 Titanium、Alloy 和 Appcelerator 云服务构建跨平台应用程序”第二章中的示例代码。我收到一个运行时错误，看起来好像未找到汽车集合，即使它在 index.js 中声明，如下所示：
我认为相关代码在 index.js 或 cars.js 中 ---
//cars.js
// Arguments passed into this controller can be accessed via the $.args` object directly or:
var args = $.args;
function doClick(e) {
alert($.label.text);
}
// controllers/cars.js
function transform(model) {
// Need to convert the model to a JSON object
var carObject = model.toJSON();
return {
"title" : carObject.model + " by " + carObject.make,
"id" : model.cid
};
}
// Show only cars made by Honda
function filter(collection) {
return collection.where({
make : 'Honda'
});
}
// NOTE: I had to add the id mytable to the xml code for the cars view
// and then change this line from $.table.add.... to get past
// another error on this line
$.mytable.addEventListener('click', function(_event) {
// get the correct model
var model = Alloy.Collections.cars._getByCid(_event.rowData.modelId);
// create the controller and pass in the model
var detailController = Alloy.createController('detail', {
data : model
});
// get view returns the root view when no view ID is provided
detailController.getView().open({
modal : true
});
});
// Free model-view data binding resources when view-controller
// closes
$.mainWindow.addEventListener('close', function() {
$.destroy();
});
并且在
//index.js
Alloy.Collections.instance("cars");
// I also tried adding --
// Alloy.Collections.cars = Alloy.createCollection('cars');
// to alloy.js but the error persists
// also tried adding --
// Alloy.Globals.cars = Alloy.createCollection('cars');
// to alloy.js but still the problem persisted
var carsController = Alloy.createController("cars");
Alloy.Collections.cars.reset([{
"make" : "Honda",
"model" : "Civic"
}, {
"make" : "Honda",
"model" : "Accord"
}, {
"make" : "Ford",
"model" : "Escape"
},{
"make" : "Nissan",
"model" : "Altima"
}]);
//$.mainWindow.open();
carsController.mainWindow.open();
index.xml 只有空的合金标签
car.xml 文件：
<Alloy>
<Window id="mainWindow" class="container">
<TableView id="mytable" dataCollection="cars" dataTransform="transform" dataFilter="filter">
<TableViewRow title="{title}" modelId="{id}"></TableViewRow>
</TableView>
</Window></Alloy>
还有一个细节控制器和视图，但我相信问题不在那里，如果你想看到它们让我知道，我会发布它们。
请帮我解决这个错误，
谢谢。
