Angularjs 学习笔记-2017-02-05-初识Angular及app、model、controller、repeat指令和fileter、orderBy

ng-app   定义作用域，从作用域处开始执行ng命令指令

ng-model 数据绑定字符，用于双向数据绑定

ng-controller ng控制台，定义function name（$scope）来填充controller内容。

ng-repeat 循环读取{{i in $scope.xx}}  or {{i in [0,1,2,3,4]}}  or　　{{i in ["aa","bb","cc"]}}

　　　　　　|filter:modelName 绑定查询标签

 

filter:

ng-repeat="phone in phones |filter:query

绑定的name与当前ng-controller或ng-app一致，当在controller中定义时，

只能在controller内可以获取到值，相当于在方法体内定义变量和在ng-app下定义公共变量

orderBy:

ng-repeat="phone in phones |orderBy:orderPro

绑定的name与当前ng-controller或ng-app一致，当在controller中定义时，

只能在controller内可以获取到值，相当于在方法体内定义变量和在ng-app下定义公共变量

 $scope 

 

Q:ng-repeat  重复读取

　　

 

<div ng-app>
    Hello {{'World'}}!


    Your name:<input type="text" ng-model="yourname" placeholder="World" />
    <hr />
    Hello   {{ yourname || 'World'}}!  {{99*5}}

    <div ng-controller="PhoneListCtrl">
        <ul>
            <li ng-repeat="phone in phones">
                <span>{{phone.name}}</span>
                <p>
                    {{phone.snippet}}
                </p>
            </li>
        </ul>
    </div>

    <p>Total number of phones: 2</p>
</div>
<script type="text/javascript">
    function PhoneListCtrl($scope) {
        $scope.phones = [
            { "name": "Nokia", "snippet": "Most memory when we was young" },
            { "name": "Motorola", "snippet": "Hello MOTO" },
            { "name": "XiaoMi4", "snippet": "Made in China" }
        ];
    }
</script>

 A:ng版本原因，引用官方地址时出现此问题，引用本地其他版本时无此问题。
