AngularJS front-end js framework
This article introduces you to the AngularJS front-end js framework. Friends in need can take a look.
Usage:
<script type="application/javascript" src="../js/angular.min.js "></script>
1. Common attributes:
ng -app: can be used on any element, represents the angular application scope, and is also the program entry point of AngularJS. It initializes the elements within the tag.
ng-controller: Controller.
ng- model: Specifies that the current element is bound to the attribute in the data model ($scope). If there is no such attribute in the data model, it will be created custom
ng-repeat: Loop the attributes in $scope.
ng-bind or {{attribute name}}: Get the attribute value.
2. Two-way binding:
Definition: Updating the view will automatically follow the new model, and updating the model will Automatically update the view.
<!-- Angular编程入口 -->
<body ng-app>
<p>
<!-- 模型 -->
<input type="text" name="name" ng-model="name " />
</p>
<p>
Hello,{{name}}!!!
</p>
</body>3. AngularJS implements MVC based on modularization:
<body>
<!-- Angular编程入口,定义一个模块 -->
<p ng-app="myapp" ng-controller="myctrl">
<p>
<!-- 模型 -->
<input type="text" name="name" ng-model="name " />
</p>
<p>
Hello,{{name}}!!!
</p>
</p>
</body>
<script type="text/javascript">
//初始化模块,第一个参数是对应的模块名称,第二个参数对应的拓展功能插件数组
var myapp = angular.module("myapp",[]);
//定义模块的控制器
/*myapp.controller("myctrl",["$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() {
$scope.name = "";
}
});
</script>5. Traversing collections of AngularJS:
ng-repeat: AngularJS is used for collection traversal and iteration.
<body>
<!-- Angular编程入口,定义一个模块 -->
<p ng-app="myapp" ng-controller="myctrl">
<table border="1" width="90%">
<tr>
<td>序号</td>
<td>商品编号</td>
<td>商品名称</td>
<td>商品价格</td>
</tr>
<tr ng-repeat="product in products">
<td>{{$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 for introducing routing:
<script type="text/javascript" src="../js/angular-route.min.js" ></script>
ng-view: Display 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>Related recommendations:

Is Django front-end or back-end? check it out!
Jan 19, 2024 am 08:37 AM
Django is a web application framework written in Python that emphasizes rapid development and clean methods. Although Django is a web framework, to answer the question whether Django is a front-end or a back-end, you need to have a deep understanding of the concepts of front-end and back-end. The front end refers to the interface that users directly interact with, and the back end refers to server-side programs. They interact with data through the HTTP protocol. When the front-end and back-end are separated, the front-end and back-end programs can be developed independently to implement business logic and interactive effects respectively, and data exchange.
