In this article, we mainly introduce the definition and usage of controller functions in AngularJS, and analyze the definition of AngularJS controller functions in combination with specific examples. , binding and related usage tips, friends in need can refer to it, I hope it can help everyone.
HTML text:
<body ng-app="myApp" ng-controller="myCtrl"> <h2>AngularJS函数绑定</h2> <textarea ng-model="message" cols="40" rows="10"></textarea> <p> <button ng-click="save()">保存</button> <button ng-click="clear()">清除</button> </p> <p>剩余字数: <span ng-bind="left()"></span></p> <!-- AngualrJS的显示和隐藏逻辑控制指令：类似avalon中的ms-visible和knockout的visible指令 --> <p ng-show="flag"> 结果：<font color="red"><span ng-bind="result"></span></font> </p>
Javascript operation code:
/**
* AngularJS将属性和函数直接看作是controller的平等成员，
* 可以调用函数按照普通的属性的调用方式即可(knockout avalon 部分Jquery插件也是使用这种方式定义函数)
*/
var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
$scope.message = "";
$scope.result="";
$scope.flag=false;
$scope.left = function() {return 100 - $scope.message.length;};
$scope.clear = function() {
$scope.message = "";
$scope.result= $scope.message;
$scope.flag=false;
};
$scope.save = function() {
$scope.result= $scope.message;
$scope.flag=true;
};
});Effect:
