一句话: 大多数html标签属性和事件都有一个对应的ng指令
说明:这些指令和原生html最大的区别就是可以动态更新.比如一个div的样式用ng-class后,我们就可以随意应用css class.
1. 内置指令大全
| ng-include | 包含一个文件 |
| ng-href ng-src | 对应 href src |
| ng-disabled ng-readonly | 对应 disabled readonly |
| ng-checked ng-selected ng-options ng-true-value ng-false-value | 对应 checked select option |
| ng-class ng-style ng-class-even ng-class-odd ng-show ng-hide ng-cloak | class style, 隔行用不同样式, 元素显示与否, 加载不完全时闪烁效果 |
| ng-switch ng-if ng-repeat ng-repeat-start ng-repeat-end | 逻辑控制 元素生成与否与遍历元素 |
| ng-submit ng-click ng-dblclick ng-change ng-mousedown ng-mouseenter ng-mouseleave ng-mousemove ng-mouseover ng-mouseup | 相应的鼠标键盘事件 |
| ng-bind ng-bind-html ng-bind-html-unsafe ng-bind-template | 绑定显示数据: 文本,半html,全html,组合模板 |
| ng-view ng-route | 路由功能 |

ng-bind-html ng-bind-html-unsafe需要引入sanitize文件,也就是说Angular不推荐html <script>
myApp.controller('BindController', function($scope, $sce) {
$scope.nb = {};
$scope.nb.textval = 'I am a text';
$scope.nb.htmlval = $sce.trustAsHtml('I am a html<strong>strong</strong> content');
