angularjs 如何从我的项模板中访问 ng-repeat 数组

Question

我想这样做...

<span ng-repeat="item in array1" ng-include="'genericItemTemplate.html'">

而这...

<span ng-repeat="item in array2" ng-include="'genericItemTemplate.html'">

然后在 genericItemTemplate.. 执行此操作...

[{{$index + 1}} of {{someArrayreference.length}}]

我可以在模板中引用 ng-repeat 的数组吗？

Answer 1

使用 onload，一个 ng-include 可选参数：

<li ng-repeat="person in personlist=friends" ng-include="'myGenericTemplate.html'"
    onload="len=friends.length"></li>
<li ng-repeat="person in personlist=collegues" ng-include="'myGenericTemplate.html'"
    onload="len=collegues.length"></li>
[{{$index + 1}} of {{len}}] {{person.name}} 

输出：

I have friends. They are:
[1 of 2] John a boy who is 25 years old.
[2 of 2] Mary a girl
I also have collegues. They are:
[1 of 3] Hoolio a boy who is 42 years old.
[2 of 3] Kitty a girl
[3 of 3] Marge a girl
