Currently i am able to display item that have parent child relation in tree structure using checkboxes. Now I need to store the checked checkboxes into one array so that I can submit that data to server via ajax.
I am new to angularjs. I tried printing using ng-model value. But it doesn't work.
Can you help me with how I can store the checked checkboxes into array.
Below is the code.
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js"></script>
<script>
var app, list;
list = [
{
name: 'Developer',
opened: true,
children: [
{
name: 'Front-End',id:1,
children: [
{
name: 'Jack',id:2,
title: 'Leader'
},
{
name: 'John',id:3,
title: 'Senior F2E'
},
{
name: 'Jason',id:4,
title: 'Junior F2E'
}
]
},
{
name: 'Back-End',id:5,
children: [
{
name: 'Mary',id:6,
title: 'Leader'
},
{
name: 'Gary',id:7,
title: 'Intern'
}
]
}
]
},
{
name: 'Design',id:8,
children: [{
name: 'Freeman',id:9,
title: 'Designer'
}]
},
{
name: 'S&S',id:10,
children: [{
name: 'Nikky',id:11,
title: 'Robot'
}]
}
];
app = angular.module('testApp', []).controller('treeTable', [
'$scope',
'$filter',
function ($scope, $filter) {
$scope.list = list;
//$scope.item.selected={};
$scope.initCheckbox = function (item, parentItem) {
return item.selected = parentItem && parentItem.selected || item.selected || false;
};
$scope.toggleCheckbox = function (item, parentScope) {
if (item.children != null) {
$scope.$broadcast('changeChildren', item);
}
if (parentScope.item != null) {
return $scope.$emit('changeParent', parentScope);
}
};
$scope.$on('changeChildren', function (event, parentItem) {
var child, i, len, ref, results;
ref = parentItem.children;
results = [];
for (i = 0, len = ref.length; i < len; i++) {
child = ref[i];
child.selected = parentItem.selected;
if (child.children != null) {
results.push($scope.$broadcast('changeChildren', child));
} else {
results.push(void 0);
}
}
return results;
});
return $scope.$on('changeParent', function (event, parentScope) {
var children;
children = parentScope.item.children;
parentScope.item.selected = $filter('selected')(children).length === children.length;
parentScope = parentScope.$parent.$parent;
if (parentScope.item != null) {
return $scope.$broadcast('changeParent', parentScope);
}
});
}
]);
app.filter('selected', [
'$filter',
function ($filter) {
return function (files) {
return $filter('filter')(files, { selected: true });
};
}
]);
</script>
