I am having an array with objects like [{...}, {...}] which I am outputting with ng-repeat. Then I have a delete button with a function to delete it.
Is there a simple way to delete it in AngularJS, perhaps with $index? Or I need to specify an ID on every object as an property?
If you don't apply a filter to reorder or filter your array, you can do this:
<div ng-repeat="item in items" ng-click="delete($index)">{{item}}</div>
And the delete function:
$scope.items = [...];
$scope.delete = function (index) {
$scope.items.splice(index, 1);
}
Another way to do it without filter problems: (ONLY IE9+)
<div ng-repeat="item in items | orderBy: 'id'" ng-click="delete(item)">{{item}}</div>
And the delete function:
$scope.items = [...];
$scope.delete = function (item) {
$scope.items.splice($scope.items.indexOf(item), 1);
}
Here is another example, using Jade too:
template.jade:
label All Items
ul.list-group
li.list-group-item(ng-repeat="item in items | orderBy: '_id'")
strong {{item.name}}
a.trash(ng-click='deleteItem(item)')
//a.trash is a bootstrap trash icon, but you don't need to use it.
controller.js:
$scope.deleteItem = function (item) {
$scope.items.splice($scope.items.indexOf(item),1);
}
removeWith comparison for each element in a collection to the given properties object, returning an array without all elements that have equivalent property values.
$scope.collection = [
{ id: 1, name: 'foo' },
{ id: 1, name: 'bar' },
{ id: 2, name: 'baz' }
]
<tr ng-repeat="obj in collection | removeWith:{ id: 1 }">
{{ obj.name }}
</tr>
<tr ng-repeat="obj in collection | removeWith:{ id: 1, name: 'foo' }">
{{ obj.name }}
</tr>
First try to do it this way, but the listing was not actualized at runtime.
$scope.delete = function (index) {
delete $scope.items[index];
}
Then with the answer given above by Facundo Pedrazzini did work properly for me.
$scope.delete = function (index) {
$scope.items.splice(index, 1);
}
Version: AngularJS v1.6.4
In blade.php
<table style="width:100%;">
<tr ng-repeat="name in planFormData.names track by $index">
<td>
<div class="form-group">
<label>Plan Name<span style="color:red;">*</span> </label>
<input type="text" class="form-control" ng-model="planFormData.names[$index].plan_name" name="plan_name" id="status-name" placeholder="Plan Name" autocomplete="off" required>
</div>
</td>
<td>
<a href="JavaScript:Void(0);"><i class="icon-plus" ng-click="addRow($index)" ng-show="$last"></i></a>
<a href="JavaScript:Void(0);"><i class="icon-trash" ng-click="deleteRow($event,name)" ng-show="$index != 0"></i></a>
</td>
</tr>
</table>
In controller.js
$scope.deleteRow = function($event, name) {
var index = $scope.planFormData.names.indexOf(name);
$scope.planFormData.names.splice(index, 1);
};
In Angular 6, I did similar for Multi Dimensional Array. It's working
RemoveThisTimeSlot(i: number, j: number) {
this.service.formData.ConsultationModelInfo.ConsultationWeekList[i].TimeBlockList.splice(j, 1);
}
