form和from寫(xiě)的好錯(cuò)亂jsvarapp=angular.module('fromApp',[]);app.controller('formController',function($scope){$scope.fromData={};$scope.check=function(){if($scope.fromData.favoriteColors){varlog=[];angular.forEach($scope.fromData.favoriteColors,function(v){if(v==true)this.push(v);},log);console.log(log.length);//length}}});
