Use*_*535 6 javascript json angularjs angularjs-ng-repeat
想要div根据从JSON收到的值显示n次.
我的目标:
$scope.pro = [
{
product: "chicken",
rating: 3
},
{
product: "fish",
rating: 3
},
{
product: "pizza",
rating: 4
}
];
如果一个产品有3个评级意味着div必须显示三次,如星级.
如何在angular.js中做到这一点？
你能试试这个吗
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);
};
