你怎么用ng-repeat做角度这样的事情？我将使用文档中的示例,其中包含2个朋友的数组,如果我只想为所有26岁及以上的朋友重复一次,该怎么办？
<!doctype html>
<html ng-app>
<head>
<script src="http://code.angularjs.org/1.0.6/angular.min.js"></script>
</head>
<body>
<div ng-init="friends = [{name:'John', age:25}, {name:'Mary', age:28}]">
I have {{friends.length}} friends. They are:
<ul>
<li ng-repeat="friend in friends">
[{{$index + 1}}] {{friend.name}} who is {{friend.age}} years old.
</li>
</ul>
</div>
</body>
</html>

创建自定义过滤器.
HTML:
<html ng-app="someApp">
和
<li ng-repeat="friend in friends | age">
JS:
var someApp=angular.module('someApp', []);
someApp.filter('age', function() {
return function(input, uppercase) {
var out = [];
for (var i = 0; i < input.length; i++) {
if(input[i].age >= 26){
out.push(input[i]);
}
}
return out;
}
});

你可以使用ng-show ="friend.age> = 26"与朋友中的ng-repeat ="朋友".它只会显示年龄大于等于26的朋友.
<body>
<div ng-init="friends = [{name:'John', age:25}, {name:'Mary', age:28}]">
I have {{friends.length}} friends. They are:
<ul>
<li ng-repeat="friend in friends" ng-show="friend.age >=26">
[{{$index + 1}}] {{friend.name}} who is {{friend.age}} years old.
</li>
</ul>
</div>
</body>
这是工作小提琴
$scope.call = function(a){
if (a.age > 26)
return true;
else
return false;
}
