将json对象加载到ng-option中

Question

<select ng-options="priority.level for priority in priority">

It return object object, what's wrong? I also tried priority[0].level, it return blank.

$scope.priority = [
    {
     "level":"High",
     "index":1
    },

    {
     "level":"Medium",
     "index":2
    },

    {
     "level":"Low",
     "index":3
    }
];

Answer 1

First of all why does your priority.level for priority in priority not work?

Counter question, would a loop like that work?

var list = [1, 2, 3, 4, 5];

for(var i = 0; list < list.length; i++) {
   list = list[i];

   // do something with list...
}

That doesn't work obviously. And you tried to do something similar.

To your sort question: You need to sort the list before you use the elements.

<ul>
  <li ng-repeat="selected in priority | orderBy:'index'">{{selected.level}}</li>
</ul>
