我正在学习AngularJS。如何调试AngularJS代码?
我创建的页面index.html
(代码见下文),这是为了显示store
模块(下面文件app.js
)中定义的变量product
的数据。它运行良好,直到我添加了评论部分。此后,占位符替换停止工作(而不是{{product.name}}
,应显示实际产品名称)。
但我无法弄清楚,究竟什么是错了。
如何调试此代码(找出原因,为什么突然间没有数据显示)?
app.js
(function(){
var app = angular.module('store', [ ]);
app.controller('StoreController', function(){
this.products = gems;
});
app.controller('PanelController', function(){
this.tab = 1;
this.selectTab = function(setTab) {
this.tab = setTab;
};
this.isSelected = function(checkTab) {
return this.tab === checkTab;
}
});
var gems = [
{
name: "Dodecahedron",
price: 2,
description: 'Some description',
canPurchase: true,
images : [
{
full: 'img01.jpg',
thumb: 'img01.jpg'
},
{
full: 'img02.jpg',
thumb: 'img02.jpg'
},
{
full: 'img03.jpg',
thumb: 'img03.jpg'
},
],
reviews = [
{
stars: 5,
body: "I love this product!",
author: "[email protected]"
},
{
stars: 1,
body: "I hate this product!",
author: "[email protected]"
},
]
},
{
name: "Pentagonal Gem",
price: 5.95,
description: 'Some description 2',
canPurchase: false,
images : [
{
full: 'img04.jpg',
thumb: 'img04.jpg'
},
{
full: 'img05.jpg',
thumb: 'img05.jpg'
},
{
full: 'img06.jpg',
thumb: 'img06.jpg'
},
]
}
]
})();
