AngularJS 基础用法

判断语句：

<li ng-repeat=”person in persons”>
<span ng-switch on=”person.sex”>
<span ng-switch-when=”1〃>you are a boy</span>
<span ng-switch-when=”2〃>you are a girl</span>
</span>
 
<span ng-if=”person.sex==1〃>you may be a father</span>
<span ng-show=”person.sex==2〃>you may be a mother</span>
 
</li>

过滤器：

$scope.childrenArray = [
        {name:'kimi',age:3},
        {name:'cindy',age:4},
        {name:'anglar',age:4},
        {name:'shitou',age:6},
        {name:'tiantian',age:5}
    ];
 //filter(匹配子串)
{{ childrenArray | filter : 'a' }} //匹配属性值中含有a的
{{ childrenArray | filter : 4 }}  //匹配属性值中含有4的
{{ childrenArray | filter : {name : 'i'} }} //参数是对象，匹配name属性中含有i的
{{childrenArray | filter : func }}  //参数是函数，指定返回age>4的

//大小写
<div ng-controller="MainCtrl">
 <h3>{{ originalText }}</h3>
 <h3>{{ filteredText }}</h3>
</div>
//js
angular.module('filterExample', [])
.controller('MainCtrl', function($scope, $filter) {
  $scope.originalText = 'hello';
  $scope.filteredText = $filter('uppercase')($scope.originalText);
});
