问题描述
我是 Angular Js 的新手.我需要在元素的点击事件中添加一个类.我尝试了以下代码.但它不起作用.
<头><风格>.active{颜色:红色；}</风格><script src="js/lib/jquery.min.js"></script><script src="js/lib/angular.min.js"></script><body ng-app="MyApp" ng-controller="MyController"><div ng-repeat="数据中的数据"><p ng-click='selectMe()'>{{data.name}}</p><脚本>var app = angular.module('MyApp',[]);app.controller('MyController',function($scope){$scope.datas = [{name:"first"},{name:"second"}];$scope.selectMe = 函数 (){$(this).addClass('active');}});
这段代码有什么问题?是否有必要使用 ng-class ?怎么做?
解决方案可以通过$event来点击
<p ng-click='selectMe($event)'>{{data.name}}</p>//代码:$scope.selectMe = 函数(事件){$(event.target).addClass('active');}I am new to Angular Js. I need to add a class to an element on its click event. I tried the following code. But it is not working.
<html> <head> <style> .active{color:red;} </style> <script src="js/lib/jquery.min.js"></script> <script src="js/lib/angular.min.js"></script> </head> <body ng-app="MyApp" ng-controller="MyController"> <div ng-repeat="data in datas"> <p ng-click='selectMe()'>{{data.name}}</p> </div> <script> var app = angular.module('MyApp',[]); app.controller('MyController',function($scope){ $scope.datas = [{name:"first"},{name:"second"}]; $scope.selectMe = function (){ $(this).addClass('active'); } }); </script> </body> </html>What is the problem in this code? Is it necessary to use ng-class ? How to do it?
解决方案You can pass $event to click
<p ng-click='selectMe($event)'>{{data.name}}</p> //code: $scope.selectMe = function (event){ $(event.target).addClass('active'); }
