Stuck on angularjs ng-checked - angularjs

Question

I'm trying to implement that when a user clicks a check box it displays all products in the ng-repeat with a quantity of 0. Else when the check box is not check all items display. Currently I was able to get half the functionality.
Check box :
<input type="checkbox" name="onoffswitch" class="onoffswitch-checkbox" id="myonoffswitch" ng-checked="vm.OnHandQty()">
Table
<tr ng-repeat="item in vm.items | filter :search">
<td ng-bind="item.itemNo"> </td>
<td ng-bind="item.description"></td>
<td ng-bind="(item.listPrice | currency)"></td>
<td ng-bind="item.onHandQty" ng-model="quantity"></td>
</tr>
Controller
vm.OnHandQty = function () {
$scope.search = {};
vm.items.forEach(i => {
if (i.onHandQty == 2) {
console.log(i);
$scope.search = i;
return true;
}
else {
$scope.search =i;
return false;
}
});
}

Answer 1

I would propose changing the implementation of your checkbox and controller:
Checkbox
<input type="checkbox" ng-model="vm.checked" name="onoffswitch" class="onoffswitch-checkbox" id="myonoffswitch">
- Here, we use "ng-model" instead of "ng-checked" and "vm.checked" is a variable that you define as the ng-model for your checkbox.
Controller
$scope.search = function(item) {
return ($scope.vm.checked) ? item.onHandQuantity === 0: true;
};
- Here, we define the "ng-repeat" filter that you are using in your table.

Try this instead:
<tr ng-repeat="item in vm.items" ng-show="onoffswitch==true && item.onHandQty != 0? false : true">
<td ng-bind="item.itemNo"> </td>
<td ng-bind="item.description"></td>
<td ng-bind="(item.listPrice | currency)"></td>
<td ng-bind="item.onHandQty" ng-model="quantity"></td>
</tr>
This will only show the row if onoffswitch is true and if the onHandQty is zero, otherwise it will show the row. So the row will be hidden if onoffswitch is true and onHandQty is not zero.

You can make use of ng-change and ng-model.
<input type="checkbox" name="onoffswitch" class="onoffswitch-checkbox" id="myonoffswitch" ng-model="vm.checked" ng-change="checkBoxChange(vm.checked)">
Then, from you checkBoxChange function, apply your business logic:
vm.checkBoxChange = function(checked){
if(checked){
//Do something
}else{
//Something else
}
};
