I'm working on a method that will receive an Id from a table when a checkbox is checked and update the $scope.selected array in my Angular controller. If the checkbox is unchecked, it should remove the corresponding item from $scope.selected.
Here's what I have so far:
$scope.updateselection = function(id) {
if ($scope.selected(sort_id) != id) { //not sure about the syntax here??
$scope.selected.push({ sort_id: id });
} else {
$scope.selected.remove({ sort_id: id });
}
};
If you're looking to handle checkbox interactions in Angular, I highly recommend using the directive provided at
Alternatively, if you prefer not to use this directive, you can set up a watcher for your checkboxes table.
Here's an example:
HTML:
<table>
<tr>
<td ng-repeat="item in items">
<input type="checkbox" ng-model="item.value">
</td>
</tr>
<table>JS:
$scope.items = [
{
name: "name1",
value: true
},
{
name: "name2",
value: false
}
];
$scope.selectedItems = [];
$scope.$watch('items', function(newValues){
$scope.selectedItems.length = 0;
angular.forEach(newValues, function(item) {
if (item.value == true) {
$scope.selectedItems.push(item.name);
}
});
console.log($scope.selectedItems);
}, true);This approach ensures that you always have up-to-date information regarding the selected checkboxes.
I've even put together a JSFiddle with a live demo for your convenience.
