假设我有一组按特定顺序排列的键
orderedNames=["mike","bob","sarah];
我有一个 JSON，我想使用 ng-repeat 显示它，但按照它们在数组中出现的顺序:
{"people":
{
"bob":{
"hair":"brown",
"eyes":"blue",
"height":"tall"
},
"sarah":{
"hair":"blonde",
"eyes":"blue",
"height":"short"
},
"mike":{
"hair":"red",
"eyes":"blue",
"height":"tall"
}
}
}
我如何编写一个文件管理器，使 ng-repeat 按照数组中指定的顺序吐出人员？
<li ng-repeat="person in people | orderNames"></li>
最佳答案
您可以定义自定义过滤器。

<!DOCTYPE html>
<html ng-app="plunker">
<head>
<meta charset="utf-8" />
<title>Filter Example</title>
<link rel="stylesheet" href="style.css" />
<script data-require="angular.js@1.2.x" src="http://code.angularjs.org/1.2.15/angular.js" data-semver="1.2.15"></script>
<script src="app.js"></script>
</head>
<body ng-controller="MainCtrl">
<li ng-repeat="person in people|orderNames:orderedNames track by $index">{{person.hair}}</li>
</body>
</html>
应用程序.js:
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.people={
bob:{
hair:"brown",
eyes:"blue",
height:"tall"
},
sarah:{
hair:"blonde",
eyes:"blue",
height:"short"
},
mike:{
hair:"red",
eyes:"blue",
height:"tall"
}
};
$scope.orderedNames=["mike","bob","sarah"];
});
app.filter("orderNames",function(){
return function(input,sortBy) {
var ordered = [];
for (var key in sortBy) {
ordered.push(input[sortBy[key]]);
}
return ordered;
};
});
