如何使用循环遍历角度$ scope变量 [英] How to iterate through angular $scope variables with a loop

问题描述

我想用这样的for循环遍历$ scope变量. 在此示例中，$ scope对象包含一个对象 accounts 包括5个对象，它们的名称是从1到5的数字.每个对象都有一个名称.

I want to iterate through $scope variables with a for loop like this. In this example the $scope object includes an object accounts inlcuding 5 objects, whose names are numbers from 1 to 5. Each of them has a name.

for(var i = 1; i < 5; i++){
   $('#name').val($scope.accounts.i.name);
}

问题: $ scope.accounts.i 是未定义，因为我不认为 $ scope内有杂物变量. 它算作字母i，因此我看不到有机会遍历带for循环的作用域. 当我在$ scope变量周围使用"时，它将仅显示为纯html，并且不会解释angular.

The problem: $scope.accounts.i is undefined because i does not count as a varibale inside the $scope variable. It counts as the letter i, so I see no chance to iterate through a scope with a for loop. When I use " " around the $scope variable it will just be displayed as plain html and angular is not interpreted.

推荐答案

上面的方法是

 $scope.accounts=[{name:"123"},{name:"124"},{name:"125"}]

            angular.forEach($scope.accounts,function(value,index){
                alert(value.name);
            })
