我想让我的 ng-repeat
按 rank
排序,我该如何写表达式?
<div ng-app="myApp" ng-controller="orderCtrl">
<ul>
<li ng-repeat="(key, value) in cars | orderBy: cars[key].rank ">
{{cars[key].longName}}</li>
</ul>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('orderCtrl', function($scope) {
$scope.cars = {
"BTC" : {
"longName" : "Bitcoin",
"rank" : 1
},
"BCH" : {
"longName" : "Bitcoin Cash",
"rank" : 3
},
"ETH" : {
"longName" : "Ethereum",
"rank" : 2
},
"ETC" : {
"longName" : "Ethereum Classic",
"rank" : 15
},
"IOTA" : {
"longName" : "IOTA",
"rank" : 4
},
"XRP" : {
"longName" : "Ripple",
"rank" : 6
},
"XVG" : {
"longName" : "Verge",
"rank" : 5
}
};
});
</script>
Order by 只能应用于数组而不是对象。您必须将对象转换为数组或创建自己的过滤器:https://justinklemm.com/angularjs-filter-ordering-objects-ngrepeat/
