angularJS1笔记-(8)-内置指令

index.html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <style>
        .colorStyle {
            color: #3e8f3e;
        }
    </style>
</head>
<body>
<div ng-app="myApp">
    <div ng-controller="firstController">
        <p>{{1+1}}</p>
        <p ng-bind="1+1">2</p>
        <p ng-bind-template="{{1+1}}"></p>
        <ul ng-init="cityArr = ['上海','北京','广州','深圳']" ng-class="{colorStyle:status}"><!--初始化指令-->
            <li ng-repeat="city in cityArr">
                <span>当前元素:{{$index}}{{city}}</span>
                <span>是否为头元素:{{$first}}</span>
                <span>是否为非头非尾元素:{{$middle}}</span>
                <span>是否为尾元素:{{$last}}</span>
            </li>
        </ul>
        <!--加载另一个页面的指令-->
        <div ng-include="'other.html'">

        </div>
        <div ng-include src="'other.html'">

        </div>

        <button ng-click="changeStatus($event)">切换状态</button>
        <p>{{status}}</p>

        <!--内置节点指令-->
        <div ng-style="{'color':'red','margin-top':'20px'}">
            你好
        </div>
        <div ng-style="defaultStyle">
            你好吗
        </div>

        <!--监听status属性的值-->
        <ul ng-switch on="status">
            <li ng-switch-when="true">
                true
            </li>
            <li ng-switch-when="false">
                false
            </li>
        </ul>

        <img src="{{src}}"/>
        <img ng-src="{{src}}"/>
    </div>
</div>

<script type="text/javascript" src="../../vendor/angular/angularJs.js"></script>
<script type="text/javascript" src="app/index.js"></script>

<script>
</script>

</body>
</html>

  other.html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>HI</title>
</head>
<body>
    另一个页面
</body>
</html>

  index.js:

var myApp = angular.module('myApp', [])

.controller('firstController',function ($scope) {
    $scope.status = false;
    $scope.changeStatus = function (event) {
        console.log(event.target);
        $scope.status = !$scope.status;
        //angular.element把angular元素转换为jquery元素
        angular.element(event.target).html('切换状态'+$scope.status);

    }
    $scope.defaultStyle = {
        color:'red',
        'margin-top':'50px'
    }

    $scope.src = "http://www.angularjs.org/img/AngularJS-large.png";
})

  运行结果:
