I'm using angularjs and I have data like this :
$scope.users = [{
name: "Pratik"
queue: [{number: "199"},{number: "111"}],
status: "OK"
}]
My view :
.available{
background-color: #00226f;
color: #f8f8f8;
}
<div class="col-xs-12 col-sm-3" ng-repeat="user in users">
<span ng-class="{'available': user.queue[0].number == 111}" class="badges ">111</span>
</div>
My problem is that I want to assign the class "available" if the queue array in users contains the number "111" at any index. In the users array the number:"111" may appear at any index so in the view I can't always use user.queue[1].number == 111 or user.queue[1].number == 111 to assign the class. I want a solution which will check if the queue array contains number:"111" and assign the class of available accordingly.
I tried to do it like this : ng-class="{'available': user.queue[i].number == 111}" but it's not working. How do I do it?
This my current workaround to apply the class:
ng-class="{'available': user.queue[0].number == 111 || user.queue[1].number == 111}"

try below code snippet
can achieve by using lodash js also using _.filter
_.filter(array, { 'number': '111' } )
Ref: https://lodash.com/docs/4.17.11#find
var myApp = angular.module('myApp',[]);
function MyCtrl($scope) {
$scope.findObjectByKey = function(array, key, value) {
for (var i = 0; i < array.length; i++) {
if (array[i][key] === value) {
return array[i];
}
}
return null;
};
$scope.users = [{
name: "Pratik",
queue: [{number: "199"},{number: "666"}],
status: "OK"
},
{
name: "Pratik 2",
queue: [{number: "111"},{number: "555"}],
status: "OK 2"
},
{
name: "Pratik 3",
queue: [{number: "999"},{number: "888"}],
status: "OK 3"
}
];
$scope.searcInArray = function(array){
// var obj = $scope.findObjectByKey(array, 'number', '111');
// using loadsh
var obj = _.filter(array, { 'number': '111' } );
return obj.length > 0;
};
}.available{
background-color: #00226f;
color: #f8f8f8;

</html>You have to add use ng-repeat to loop all queue and find how has item.number == '111'
<div class="col-xs-12 col-sm-3" ng-repeat="user in users">
<div ng-repeat="item in user.queue">
<span ng-class="{'available': item.number == '111'}" class="badges ">111</span>
</div>
</div>
NOTE!
if you want show only the item.number == '111' you can use ng-hide/show
