Ajax提交无法在Ionic App中使用

Question

当使用离子运行-l在设备上测试应用程序时，会发生ajax提交，但$ cordovaSqllite.execute（）会抛出错误。

使用离子上传在Ionic View中运行相同的应用程序时，不会发生ajax提交。

controller.js

angular.module('starter.controllers', []) 
.controller('IssueCtrl', function($scope,$http,$ionicPopup,$cordovaSQLite) {


   var db = $cordovaSQLite.openDB({ name: "my.db" });
   var sql ="CREATE TABLE IF NOT EXISTS issues (queryid integer,customer text,contact text,address text,issue text,status text";

     $cordovaSQLite.execute(db,sql,[]).then(function(res){});
    $scope.processform =function(){   

      $http({
          method  : 'POST',
          url     : 'http://path to my folder/data.php',
          data    : $.param($scope.formData),  // pass in data as strings
          headers : { 'Content-Type': 'application/x-www-form-urlencoded' }  // set the headers so angular passing info as form data (not request payload)
         })
  .success(function(data) {

    var sql='INSERT INTO issues (queryid, customer,contact,address,issue,status) VALUES ('+data+', "'+$scope.formData.customer+'","'+$scope.formData.contact+'","'+$scope.formData.address+'","'+$scope.formData.issue+'","Open")';

  $cordovaSQLite.execute(db,sql,[]).then (function(res){
    console.log(res.data);

    $ionicPopup.alert({
     title: 'Done!',
     template: 'Done'

   });
  });  
});

}
