Menu
Want to show a div n times according to the value which was received from JSON.
My object:
$scope.pro = [
{
product: "chicken",
rating: 3
},
{
product: "fish",
rating: 3
},
{
product: "pizza",
rating: 4
}
];
If a product has 3 ratings means the div have to show three times, like a star rating.
How to do it in angular.js?

Can you try this,
JS
$scope.pro = [{product: "chicken", rating: 3},{product: "fish", rating: 3},{product: "pizza", rating: 4}];
var ratingTotal = 5;
$scope.getRepeater = function() {
return new Array(ratingTotal);
};

Note: The class name for selected star is mentioned as 'full' and feel free to change this.

geNumber() will create an empty array with the size of the rating. ng-repeat will iterate over it no matter what is inside
track by $index is necessary in this case because you will display multiple times the same value and duplicates in a repeater are not allowed
var app = angular.module('myApp', []);
app.controller('myController', function($scope) {
$scope.pro = [{
product: "chicken",
rating: 3
}, {
product: "fish",
rating: 3
}, {
product: "pizza",
rating: 4
}];
$scope.getNumber = function(num){
return new Array(num);
}
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="myApp" ng-controller="myController">
<div ng-repeat="item in pro">
<div ng-repeat="n in getNumber(item.rating) track by $index">
{{item.product}}
</div>
</div>
