AngularJS - 模板不起作用
aBh*_*jit 3 templating angularjs route-provider restangular mean-stack
我使用Restangular来创建一个使用MEAN堆栈的简单API.
这是我的代码:

我的应用程序的第一页加载完全正常.这是截图.
但是,当我点击任一编辑链接时,它应该加载edit.html模板.但它显示一个空白页面,在控制台中没有错误.这是截图.
我无法弄清楚出了什么问题.请帮忙.请询问是否需要任何其他代码.我几乎添加了我所做的一切.我知道它很烦人,不推荐但我不确定我的代码的哪一部分导致了这个问题.
编辑1:
我最大的猜测是,edit.html的网址可能无法正确解析.但我不确定如何测试!任何帮助都会得到满足.
编辑2:目录结构
解决方案:礼貌@ashu
问题是index.html中的这一行
<script src="app.js"></script>
它应该是:
<script src="/app.js"></script>
但是,我不清楚为什么!页面包括app.js.真奇怪.
你有相同的角度和快递路线.
.when('api/todos/:todo_id',{
templateUrl: 'edit.html',
controller: 'EditController'
});
并在快递
app.get('/api/todos/:todo_id', function(req, res) {
因此,存在歧义.您可以从角网址中删除'api'部分.
.when('/todos/:todo_id', {
templateUrl: 'edit.html',
controller: 'EditController'
})
在服务器中,您可以添加一个可以处理所有非api URL的catchall路由.为此,您可以app.get('/', function(req,res) {..})在定义api路由后在底部移动您的呼叫.
// < Define APi Routes here >
//catch all route for serving the html template
app.get('/*', function(req, res ) {
res.sendfile('./public/index.html')
});
此外,在您的app.js EditController中,您忘记初始化id的值.
var id = $routeParams.todo_id;
