如何使用Angularjs检查值是否在数组列表中退出 [英] How Do I Check A Value Is Exits Or Not In A Array List Using Angularjs

问题描述

 $ scope.Validate = function（）{
 $ scope.Email = {}; 
 $ http.get（'  index.php / Welcome / EmailCheck'）。success（ function（result）{
 
 $ scope.Email = result; 
 
 console.log（result）; 
 
}）; 
 
}; 
 $ scope.submitForm = function（）{
 
  if （$ scope.Email.Email === $ scope.user .Email）{
 console.log（  Mail Id Alresdy Exists）; 
} 
  else  
 {
 $ http（{
 method：'  POST'，
 url：'  index.php / Welcome / Signup'，
 data：$ scope.user，
 headers：{'  Content-Type'：'  application / x- www-form-urlencode'} 
}）。success（function（data）{
 $ scope.Enquiry = data; 
 console.log（data）; 
 $ location.path（'  / EnquiryResponse'）; 
}）; 
} 
; 
}; 

验证函数 $ scope.Email 从数据库中获取所有电子邮件ID它是一个 arraylist ，

在Submitform函数中，我从ui获得了一个电子邮件ID，我将电子邮件存储在$ scope.user.Email中。

现在我想检查单个电子邮件（$ scope.user.Email）是否存在于多个电子邮件ID （$ scope.Email） ...

解决方案

scope.Validate = function（）{

scope.Email = {};

< blockquote> http.get（' index.php / Welcome / EmailCheck'）。success（function（result） ）{

$scope.Validate = function () {
               $scope.Email = {};
               $http.get('index.php/Welcome/EmailCheck').success(function (result) {

                   $scope.Email = result;

                   console.log(result);

               });

           };
           $scope.submitForm = function () {

               if ($scope.Email.Email === $scope.user.Email) {
                   console.log("Mail Id Alresdy Exists");
               }
               else
               {
                   $http({
                       method: 'POST',
                       url: 'index.php/Welcome/Signup',
                       data: $scope.user,
                       headers: {'Content-Type': 'application/x-www-form-urlencode'}
                   }).success(function (data) {
                       $scope.Enquiry = data;
                       console.log(data);
                       $location.path('/EnquiryResponse');
                   });
               }
               ;
           };

in Validate function $scope.Email getting all Email ids from database and it is a arraylist,
in Submitform function i got a single Email Id from ui i have stored the Email in $scope.user.Email.
now i want to check single Email($scope.user.Email) is Existing or not in Many Email Id($scope.Email)...

解决方案

scope.Validate = function () {

scope.Email = {};

http.get('index.php/Welcome/EmailCheck').success(function (result) {
