AngularJs遇到的小坑与技巧

1. templateURL和路由之类的要在web server下运行。

2. 使用模板replace设为true，模板里也要有相应的标签，否则不出现任何数据。

3. 1.2版本之后，ngRoute模块独立。

4.空的controller不定义会出错。

5.Directive的link参数是有顺序的:scope,element,attrs,ctrl

6.ng-repeat不能循环重复的对象。hack:

ng-repeat

=

"thing in things track by $id($index)"

7.尽量更新的是变量的属性而不是单个变量本身。

8.注意ng-repeat,ng-controller等会产生独立作用域。

9.当jquery载入，则使用jquery，否则使用内置jqlite。all element references in Angular are always wrapped with jQuery or jqLite; they are never raw DOM references.

10.Uncaught Error: [$location:ihshprfx] A标签没有去掉 <a href="#" ng-click="someMethod();"></a>

11.Error: listen EACCES 当在linux下，会出现这个错误，因为你监听的端口的原因，这里我的是33。把它改成8080或3030之类大的端口数就可以了。有一个规定，这些端口最好是大于1024。

12. select在没有ng-model的时候，无法显示。同理，当遇到无法显示最好看文档少了什么。

补：当ng-options的源，跟书写不相配时会出现全部选择的情况，如下：

var a = [{"id":1,"name":"Ryan"}....] ,ng-options="item.i as item.name for item in a" // i与id不同

----------------------------------------------------------------------------------------

13.ng-bind-html-unsafe已去除，可以用

['ngSanitize'] 模块或使用

$sce服务

From stackoverflow

You indicated that you're using Angular 1.2.0... as one of the other comments indicated, ng-bind-html-unsafe has been deprecated.

Instead, you'll want to do something like this:

<div ng-bind-html="preview_data.preview.embed.htmlSafe"></div>

In your controller, inject the $sce service, and mark the HTML as "trusted":

myApp.controller('myCtrl', ['$scope', '$sce', function($scope, $sce) {
// ...
$scope.preview_data.preview.embed.htmlSafe =
$sce.trustAsHtml(preview_data.preview.embed.html);
}

Note that you'll want to be using 1.2.0-rc3 or newer. (They fixed a bug in rc3 that prevented "watchers" from working properly on trusted HTML.)

持续更新中...
