This article mainly shares with you the request method of the JAngularJS front-end framework. It has a good reference value and I hope it will be helpful to everyone. Let’s follow the editor to take a look, I hope it can help everyone.
Usage:
<script type="application/javascript" src="../js/angular.min.js "></script>
1. Common attributes:
ng-app: Can be used on any element, representing angular application function The domain is also the program entrance of AngularJS, which initializes the elements in the tag.
ng-controller: controller.
ng-model: Specifies the current element and the data model ($scope) Attribute binding, if there is no such attribute in the data model, it will be created custom
ng-repeat: Loop the attributes in $scope.
ng-bind or {{attribute name}}: Get attribute values.
2. Two-way binding:
Definition: Updating the view will automatically follow the new model, and updating the model will automatically update the view.
<!-- Angular编程入口 --> <body ng-app> <p> <!-- 模型 --> <input type="text" name="name" ng-model="name " /> </p> <p> Hello,{{name}}!!! </p> </body>
3. AngularJS implements MVC based on modularization:
<body> <!-- Angular编程入口,定义一个模块 --> <p ng-app="myapp" ng-controller="myctrl"> <p> <!-- 模型 --> <input type="text" name="name" ng-model="name " /> </p> <p> Hello,{{name}}!!! </p> </p> </body> <script type="text/javascript"> //初始化模块,第一个参数是对应的模块名称,第二个参数对应的拓展功能插件数组 var myapp = angular.module("myapp",[]); //定义模块的控制器 /*myapp.controller("myctrl",["$scope",function($scope){ $scope.name="沃德发"; }])*/ //$scope页面与控制器的桥梁 myapp.controller("myctrl",function($scope){ $scope.name="法克鱿"; }); </script>
4. AngularJS event binding:
ng-click: AngularJS Click event.
<body> <!-- Angular编程入口,定义一个模块 --> <p ng-app="myapp" ng-controller="myctrl"> <p> <!-- 模型 --> <input type="text" name="name" ng-model="name " /> <input type="button" value="清空" ng-click="clearVal()"/> </p> <p> Hello,{{name}}!!! </p> </p> </body> <script type="text/javascript"> //初始化模块,第一个参数是对应的模块名称,第二个参数对应的拓展功能插件数组 var myapp = angular.module("myapp",[]); //$scope页面与控制器的桥梁 myapp.controller("myctrl",function($scope){ $scope.name="嗯嗯啊"; //事件绑定 $scope.clearVal = function() { $scope.name = ""; } }); </script>
5. AngularJS traversal collection:
ng-repeat: AngularJS is used for collection traversal and iteration.
<body> <!-- Angular编程入口,定义一个模块 --> <p ng-app="myapp" ng-controller="myctrl"> <table border="1" width="90%"> <tr> <td>序号</td> <td>商品编号</td> <td>商品名称</td> <td>商品价格</td> </tr> <tr ng-repeat="product in products"> <td>{{$index+1}}</td> <td>{{product.id}}</td> <td>{{product.name}}</td> <td>{{product.price}}</td> </tr> </table> </p> </body> <script type="text/javascript"> //初始化模块,第一个参数是对应的模块名称,第二个参数对应的拓展功能插件数组 var myapp = angular.module("myapp",[]); myapp.controller("myctrl",function($scope){ $scope.products=[ { id:'A001', name:'狗子', price:3306 },{ id:'A002', name:'啥子哟', price:8080 } ] }); </script>
6. Routing of AngularJS:
JS that introduces routing:
<script type="text/javascript" src="../js/angular-route.min.js" ></script>
ng-view: Displays the page called by routing
$routeProvider : Routing system
when..when..otherwise : Similar to switch..case..case..default
<!-- Angular编程入口 --> <body ng-app="myapp"> <p> <h1>HEAD</h1> <a href="#/aa">首页</a> <a href="#/bb">*</a> <a href="#/cc">站长推荐</a> </p> <!-- ng-view显示路由调用页面 --> <p ng-view> </p> <p> <h1>FOOT</h1> </p> </body> <script type="text/javascript"> var myapp = angular.module("myapp",["ngRoute"]); myapp.config(["$routeProvider",function($routeProvider){ $routeProvider.when("/aa",{ templateUrl:'aa.html' }).when("/bb",{ templateUrl:'bb.html' }).when("/cc",{ templateUrl:'5_3.html' }).otherwise({ redirectTo:"/" }); }]); </script>
