如何按键作为整数排序？
我有以下对象
$scope.data = {
"0": { data: "ZERO" },"1": { data: "ONE" },"2": { data: "TWO" },"3": { data: "TREE" },"5": { data: "FIVE" },"6": { data: "SIX" },"10":{ data: "TEN" },"11": { data: "ELEVEN" },"12": { data: "TWELVE" },"13": { data: "THIRTEEN" },"20": { data: "TWENTY"}
}
HTML：
<div ng-repeat="(key,value) in data">
目前的出货订单为1,10,11,12,13,14,2,20,3,4,5,6
但我想要1,6,20
| orderBy:key
不为我工作
有任何想法吗？
谢谢！
一个选项将使用中间过滤器。
PLUNK AND Code Snippet
var app = angular.module('app',[]);
app.controller('MainCtrl',function($scope) {
$scope.template = {
"0": { data: "ZERO" },"20": { data: "TWENTY"}
}
});
app.filter('toArray',function() { return function(obj) {
if (!(obj instanceof Object)) return obj;
return _.map(obj,function(val,key) {
return Object.defineProperty(val,'$key',{__proto__: null,value: key});
});
}});

注意：
上述过滤器需要Underscore.js，如果不使用它，可以重写过滤器。
