如何按键排序为整数?
我有以下对象;
$scope.data = { "0": { data: "ZERO" }, "1": { data: "ONE" }, "2": { data: "TWO" }, "3": { data: "TREE" }, "5": { data: "FIVE" }, "6": { data: "SIX" }, "10":{ data: "TEN" }, "11": { data: "ELEVEN" }, "12": { data: "TWELVE" }, "13": { data: "THIRTEEN" }, "20": { data: "TWENTY"} }
HTML:
<div ng-repeat="(key,value) in data">
当前的输出顺序是 1,10,11,12,13,14,2,20,3,4,5,6
1,10,11,12,13,14,2,20,3,4,5,6
但是我想要 1,2,3,4,5,6,10,11,12,13,14,20
1,2,3,4,5,6,10,11,12,13,14,20
| orderBy:key
不要为我工作。
有任何想法吗?
谢谢!
一种选择是使用中间过滤器。
var app = angular.module('app', []); app.controller('MainCtrl', function($scope) { $scope.template = { "0": { data: "ZERO" }, "1": { data: "ONE" }, "2": { data: "TWO" }, "3": { data: "TREE" }, "5": { data: "FIVE" }, "6": { data: "SIX" }, "10":{ data: "TEN" }, "11": { data: "ELEVEN" }, "12": { data: "TWELVE" }, "13": { data: "THIRTEEN" }, "20": { data: "TWENTY"} } }); app.filter('toArray', function() { return function(obj) { if (!(obj instanceof Object)) return obj; return _.map(obj, function(val, key) { return Object.defineProperty(val, '$key', {__proto__: null, value: key}); }); }}); <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <script src="//cdnjs.cloudflare.com/ajax/libs/underscore.js/1.7.0/underscore.js"></script> <body ng-app="app" ng-controller="MainCtrl"> <div ng-repeat="(key, value) in template| toArray | orderBy:key">{{key}} : {{value.$key}} : {{value.data}}</div> <body>
上面的过滤器需要Underscore.js,如果不使用它,可以重写过滤器。
