I have an Ionic application(it work the same like Angularjs) and I have a little problem.
<ion-list class="list-inset subcategory" ng-repeat="item in shops">
<ion-checkbox class="item item-divider item-checkbox-right" ng-model="selectAll">
{{item}}
</ion-checkbox>
<ion-item ng-repeat="value in data | filter:{shopName: item}" class="item-thumbnail-left" ng-click="openProduct(value)">
...
<div class="row">
<ion-checkbox stop-event='click' ng-model="value.selected" ng-checked="selectAll">{{value.name}}</ion-checkbox>
</div>
...
</ion-list>
When I click on item with ng-model="selectAll"
all items is selected. But I have property value.selected
. It sets false for each one value
. When I click on item with ng-model="value.selected"
it changes. But when I want selec all and click on item with ng-model="selectAll"
this propety doesn't change. Help me please.
Note: I have ng-repeat in the ng-repeat. First ng-repeat is for shops, the second is for products. And I have a filter by shopName. And I want select all by shops. Now it works how I want, but doesn't change property value.selected
. Value it is produt, item it is shop.
the state of selectAll
can be derived from the state of your other check boxes so it should not be stored as a seperate field.
You could use a getterSetter on the selectAll model to determine weather it should be checked. eg
<input type="checkbox" ng-model="selectAll" ng-model-options="{getterSetter: true}"/>
JS
var getAllSelected = function () {
var selectedItems = $scope.Items.filter(function (item) {
return item.Selected;
});
return selectedItems.length === $scope.Items.length;
}
var setAllSelected = function (value) {
angular.forEach($scope.Items, function (item) {
item.Selected = value;
});
}
$scope.selectAll = function (value) {
if (value !== undefined) {
return setAllSelected(value);
} else {
return getAllSelected();
}
}
you can use ngClick
on the item with ng-model="selectAll"
. you can call a function in ng-click and then make selected=true for all other items where ng-model="value.selected"
.
