angularjs - How to select and delete multiple rows sqlite - angularjs

Question

I have this app where I take picture and save the image URL into the sqlite .
i can add, delete and display all of them , now i'm trying to select multiple (images) from the db with the ids and delete the selected ones
$scope.selected = [];
$scope.deleteMultiple = function(){
var selectedImages = [];
angular.forEach($scope.selected, function(isSelected, index) {
if(isSelected)
selectedImages.push($scope.images[$index])
$scope.delete(selectedImages.id)
})
console.log(selectedImage)
}
$scope.add = function(path) {             
if (imagesP != null) {          
$cordovaSQLite.execute(db, "INSERT INTO imageTable (images) VALUES(?)", [path] );        
}        
alert("Inserted.");      
},
function(e) {        
alert(e);      
};
$scope.delete = function(id) {                
if (id != '') {          
$cordovaSQLite.execute(db, "DELETE FROM imageTable WHERE id=?", [id]);        
}        
alert("Deleted.");        
$scope.ShowAllData();      
},
function(e) {        
alert(e);      
};    
  
$scope.getImgIDbyName = function(name) {
console.log('[getImgIDbyName] - get image with name: ' + name );
var sql = "SELECT * FROM imageTable WHERE image = '" + name + "';";
console.log(sql);
$cordovaSQLite.execute(db,
sql
).then(
function(res) {
if (res.rows.length > 0) {
if (res.rows.length > 1) {
console.log('[getImgIDbyName] - OOPS more than 1 image returned!!!! ' + name );
} else {
$scope.delete (res.rows.item(0).id);
}
} else {
console.log('[getImgIDbyName] - no image found with name: ' + name );
}
},
function(error) {
alert("error occured: " + error.message);
}
);
}
HTML
<div ng-repeat="image in images " > <!-- container -->
<div>
<img ng-src="{{image.image}}" style="width: 70%; height: 80%;" ng-class="{'selected-image': selected[$index]}" ng-click="selected[$index] = !selected[$index] />
<div ng-click="getImgIDbyName(image.image)">
<div style="font-size:2rem;margin:0.5rem 0 1rem" > DELETE IMAGE (ID:{{image.id}}) </div>
</div>
</div>
</div>

The below code should do multiple delete as you are expecting:
$scope.selected = [];
$scope.deleteMultiple = function(){
var selectedImages = [];
var selectIDs = $scope.selected.map(function(x) {return x +',';};
console.log(selectedImages.selectIDs)
$scope.delete(selectedImages.selectIDs)
}
$scope.delete = function(ids) {
if (ids != '') {
$cordovaSQLite.execute(db, "DELETE FROM imageTable WHERE id IN (?)", [ids]);
}
alert("Deleted.");
$scope.ShowAllData();
},
