angularjs如何判断checkbox选中2个

Question

RedBlueGreen提交varapp=angular.module('fromApp',[]);app.controller('formController',function($scope){$scope.fromData={};$scope.check=function(){}});如何实现点击提交当checkbox选中超过2个做出提示即可

Answer 1

form和from写的好错乱
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
}
}
});
