How to hide button in ng-repeat in AngularJS? - html

Question

My View:
<div class="col-sm-4 col-xs-4" ng-repeat="(id, object) in objects">
<button type="primary"
ng-click="add(id)"
ng-hide="id.plz" style="color: cyan;">Add</button>
</div>
Controller JavaScript:
$scope.add = function(id){
// some function;
$scope.objects[id].plz = true;
}
Any idea why it won't work?

Answer 1

<div class="col-sm-4 col-xs-4" ng-repeat="(id, object) in objects">
<button type="primary" ng-hide="objects[id].plz" ng-click="add(id)" style="color: cyan;" >Add</button>
<div>
here in ng-hide="id.plz" id is the index so there is no id.plz

If you want to conditionally hide your button in ng-repeat, use ng-hide, ng-show(if there is a chance that you will hide and show it later) or ng-if(if it's a one time hide of button).
ng-hide takes a boolean and shows/displays accordingly. In your case your ng-hide is always turned out to be true, so you are unable to hide. Just write the condition required in your ng-hide to hide your button

Hide the button when its clicked like in this fiddle:
View
<div ng-controller="MyCtrl">
<div ng-repeat="user in data">
{{ user.name}}
<button ng-hide="hide[$index]" ng-click="add();hide[$index] = true;">
Add
</button>
</div>
</div>
AngularJS application
var myApp = angular.module('myApp',[]);
myApp.controller('MyCtrl', function ($scope) {
$scope.add = function () {
console.log('add');
}
$scope.data = [{
name: 'frank'
},{
name: 'peter'
},{
name: 'melanie'
},{
name: 'sven'
},{
name: 'basti'
},{
name: 'edjuh'
}];
});
