提问by itsme
Hi i installed the following module https://github.com/likeastore/ngDialog
嗨，我安装了以下模块https://github.com/likeastore/ngDialog
it works great but i can't get how to open the dialog box from a controller, i do:
它工作得很好，但我无法从控制器中打开对话框，我这样做：
var app = angular.module('app', ['ngRoute','ngAnimate','ngSanitize','ngDialog']);
app.controller('SignupController', function($rootScope,$scope) {
$scope.signup = function(){
var error = false,
error_list = "ERRORS";
if(!$scope.signup_username){
error = true;
error_list += "\n\n Username \n " + $rootScope.errors.required_field;
}if(!$scope.signup_email){
error = true;
error_list += "\n\n Email \n " + $rootScope.errors.valid_email;
}if(!$scope.signup_password){
error = true;
error_list += "\n\n Password \n " + $rootScope.errors.required_field;
}
if(error){
ngDialog.open({template:error_list,plain:true});
}else{
//register
}
}
});
But it doesn't works as expected, cause i get console error : ngDialog is not defined.
但它没有按预期工作，因为我收到控制台错误：未定义 ngDialog。

Your controller is not taking a dependency on ngDialog so it is an unknown variable at runtime.
您的控制器不依赖于 ngDialog，因此它在运行时是一个未知变量。
app.controller('SignupController', function($rootScope, $scope, ngDialog) {
$scope.signup = function(){
var error = false,
error_list = "ERRORS";
if(!$scope.signup_username){
error = true;
error_list += "\n\n Username \n " + $rootScope.errors.required_field;
}if(!$scope.signup_email){
error = true;
error_list += "\n\n Email \n " + $rootScope.errors.valid_email;
}if(!$scope.signup_password){
error = true;
error_list += "\n\n Password \n " + $rootScope.errors.required_field;
}
if(error){
ngDialog.open({template:error_list,plain:true});
}else{
//register
}
}
});
