AngularJS - ngRepeat with multiple object types
提问by Shlomi Schwartz
I have a list of items. An item can be a number of things, let's say the list is something like so :
我有一个物品清单。一个项目可以是很多东西，假设列表是这样的：
[userObject , vehicleObject , userObject , animalObject , animalObject]
Now I want to render the list with ngRepeat directive that will use a template according to the type of the object (Polymorphic rendering). can this be done?
现在我想用 ngRepeat 指令渲染列表，该指令将根据对象的类型（多态渲染）使用模板。可以这样做吗？
maybe something like (ng-useis an hypotheticallydirective):
也许像（ng-use是一个假设的指令）：
<ul>
<li ng-repeat="item in items">
<img ng-use="item.type == 'user'" ng-src="item.src">
<a ng-use="item.type == 'vehicle'">{{item.link}}</a>
<span ng-use="item.type == 'animal'">{{item.name}}</span>
</li>
</ul>

<ul>
<li ng-repeat="item in items" ng-switch="item.type">
<img ng-switch-when="user" ng-src="item.src">
<a ng-switch-when="vehicle">{{item.link}}</a>
<span ng-switch-when="animal">{{item.name}}</span>
</li>
</ul>

Although this doesn't use ng-switch, it does get round the problem of not having a typefield, which @DotNetHaggis pointed out.
虽然这不使用 ng-switch，但它确实解决了没有类型字段的问题，@DotNetHaggis 指出了这一点。
<div ng-repeat="field in fields">
<div ng-if="field.user !== undefined">user info</div>
<div ng-if="field.vehicle !== undefined">vehicle info</div>
<div ng-if="field.animal !== undefined">animal info</div>
</div>
