check a checkbox by clicking a link in angularJs - angularjs

Question

I have the folowing code :
<li ng-repeat="item in items">
<a href="#" ng-if="!item.children" ng-click="checkItem(item,checkBoxModel)">
<input class="align"
ng-click="checkItem(item,checkBoxModel)"
type="checkbox" ng-checked="master"
ng-model="checkboxModel"/>
{{ item.title }}
</a>
</li>
in my controller i have checkItem function:
$scope.checkItem = function(item, checkBoxModel) {
if (checkBoxModel == undefined || checkBoxModel == true) {
....
$scope.master=true;
$scope.checkBoxModel = false;*
} else {
....
$scope.master = false;
$scope.checkBoxModel = true;
}
}
The problem is that when I click on a link all of the checkboxes are checked. I just want the checkbox associated to the link to be checked.

Answer 1

Instead of setting a value master on the controllers $scope object, set it on the actual item that you pass in, and set it's ng-checked="item.master" and it's ng-model="item.checkBoxModel"
$scope.checkItem = function(item, checkBoxModel) {
if (checkBoxModel == undefined || checkBoxModel == true) {
....
item.master=true;
item.checkBoxModel = false;
} else {
....
item.master = false;
item.checkBoxModel = true;
}
}

Change your app logic. You have to declare a variable for each item. But as i see, you have one for all in the global $scope named master. The master should have been declared for each item to specify the state of the option box. Then your problem will be solved.
Something like this:
app.js
$scope.items = [
{
name: 'example',
master: false,
checkboxModel: false
},
{
name: 'example',
master: false,
checkboxModel: false
}
];
$scope.checkItem = function(item, checkBoxModel) {
if (checkBoxModel == undefined || checkBoxModel == true) {
....
$scope.items[item].master = true;
...
} else {
....
$scope.items[item].master = false;
...
}
}
index.html
<input class="align"
ng-click="checkItem(item, checkBoxModel)"
type="checkbox" ng-checked="item.master"
ng-model="item.checkboxModel"/>
