I want to auto select the Checkbox if it already exists in the model
I tried with the following code
Controller
$scope.model = {
items: [{"key":1, "value": "One"},{"key":2, "value": "Two"},{"key":3,
"value": "Three"},{"key":4, "value": "Four"},{"key":5, "value": "Five"}]
};
$scope.selected = [{"key":2, "value": "Two"},{"key":5, "value": "Five"}];
$scope.toggle = function(item, list) {
var idx = list.indexOf(item);
if (idx > -1) {
list.splice(idx, 1);
} else {
list.push(item);
}
};
$scope.exists = function(item, list) {
return list.indexOf(item) > -1;
};
HTML
<div flex="25" ng-repeat="item model.items">
<md-checkbox ng-checked="exists(item, selected)"
ng-click="toggle(item, selected)">
{{ item.value }}
</md-checkbox>
</div>
But the checkbox for Key '2' and '5' not selected by default.
If I replace the following code,
$scope.exists = function (item, list) {
for (var i = 0; i < list.length; i++) {
if (list[i].key === item.key) {
return true;
}
}
return false;
};
It selects 2 and 5 while page loading but not able un check both. Other 1,3 and 4 works as expected.
A solution off the top of my head
<div flex="25" ng-repeat="item model.items">
<md-checkbox ng-model="item.selected"
ng-click="toggle(item, selected)">
{{ item.value }}
</md-checkbox>
</div>
so use ng-model and to set default
$scope.model = {
items: [{"key":1, "value": "One"},{"key":2, "value": "Two", selected: true},{"key":3,
"value": "Three"},{"key":4, "value": "Four"},{"key":5, "value": "Five", selected: true}]
};
later to get a selected items you just need to use
$scope.model.items.filter(function(item){return item.selected});
