AngularJS参数绑定 --AngularJS

AngularJS参数绑定有三种方式。第一种插值表达式“｛｛｝｝”表示，第二种在标签中使用ng-bind属性表示，第三种针对input框(标签)的ng-module属性表示。针对三种参数绑定方式，设定了以下三个小案例。

1、插值表达式

案例核心代码：

demo01.html:

<!DOCTYPE html>
<html lang="en" ng-app="myapp">
<head>
    <meta charset="UTF-8">
    <title>AnjularJS数据绑定-插值表达式</title>
</head>
<body>
<div ng-controller="demo01Controller">
    <span>{{name}}</span>
    <span>{{num1+num2}}</span>
    <span>{{num1*num2}}</span>
    <span>{{obg.address}}</span>
    <span>{{address[0]}}</span>
    <ul>
        <li ng-repeat="item in address track by $index">{{item}}</li>
    </ul>
    <ul>
        <li ng-repeat="item in university">
            {{item.name}}
            <ul>
                <li ng-repeat="childItem in item.xueyuan">{{childItem}}</li>
            </ul>
        </li>
    </ul>
</div>
<script src="../js/angular.min.js"></script>
<script src="../js/app_module.js"></script>
<script src="../js/demo01Controller.js"></script>
</body>
</html>

2、ng-bind

案例核心代码：

demo02.html:

<!DOCTYPE html>
<html lang="en" ng-app="myapp">
<head>
    <meta charset="UTF-8">
    <title>AnjularJS数据绑定-ng-bind表示</title>
</head>
<body>
<div ng-controller="demo02Controller">
    <span ng-bind="name"></span>
    <span ng-bind="num1+num2"></span>
    <span ng-bind="num1*num2"></span>
    <span ng-bind="obg.address"></span>
    <span ng-bind="adress[0]"></span>
    <ul>
        <li ng-repeat="item in address track by $index" ng-bind="item"></li>
    </ul>
    <ul>
        <li ng-repeat="item in university">
            {{item.name}}<!--这里用插值表达式,考虑为什么？-->
            <ul>
                <li ng-repeat="childItem in item.xueyuan" ng-bind="childItem"></li>
            </ul>
        </li>
    </ul>
</div>
<script src="../js/angular.min.js"></script>
<script src="../js/app_module.js"></script>
<script src="../js/demo02Controller.js"></script>
</body>
</html>

案例效果：（同1）

3、ng-module

案例核心代码：

demo03.html：

<!DOCTYPE html>
<html lang="en" ng-app="myapp">
<head>
    <meta charset="UTF-8">
    <title>AnjularJS数据绑定-ng-module(针对input框)表示</title>
</head>
<body>
<div ng-controller="demo03Controller">
    <input type="text" ng-model="name">
    <!--双向绑定-->
    <p>{{name}}</p><!--或者是<p ng-bind="name"></p>-->
</div>
<script src="../js/angular.min.js"></script>
<script src="../js/app_module.js"></script>
<script src="../js/demo03Controller.js"></script>
</body>
</html>
