导读:我想知道如何做的工作这个片段: //htmldiv ng-app="app"div ng-controller="AppCtrl" a my-dir ng-repeat="user in users"{{user.name}}/a/div/div//jsvar app = angular.module('app',[]); app.controller("AppCtrl",function ($scope) { $scope.users = [
我想知道如何做的工作这个片段:
//html <div ng-app="app"> <div ng-controller="AppCtrl"> <a my-dir ng-repeat="user in users">{{user.name}}</a> </div> </div> //js var app = angular.module('app',[]); app.controller("AppCtrl",function ($scope) { $scope.users = [{name:'John',id:1},{name:'anonymous'}]; $scope.fxn = function() { alert('It works'); }; }) app.directive("myDir",function ($compile) { return { link:function(scope,el){ el.attr('ng-click','fxn()'); //$compile(el)(scope); with this the script go mad } }; }); 我知道这是关于编译阶段
将另一个伪指令添加到同一元素的伪指令:
