我有一个循环器,循环遍历一个类型列表。根据类型值,它将显示相应的指令。我有几个指令叫做:dropdown,Long text,Choice,multichoice等。转发器将循环遍历类型列表以显示匹配指令
<div ng-repeat="field in model.Fields">
<!-- if field = text then render longtext directive -->
<!-- if field = dropdown then render dropdown directive -->
<!-- if field = choice then render choice directive -->
<!-- and so on -->
</div>
有优雅的方法吗?顺便说一句,您可以将此邮件的标题更改为更合适的标题。

Angular的ng-switch
指令可能更合适:
<div ng-repeat="field in model.Fields">
<div ng-switch on="field">
<div ng-switch-when="text" longtext>
<!-- Render the longtext directive -->
</div>
<div ng-switch-when="dropdown" dropdown>
<!-- Render the longtext directive -->
</div>
<div ng-switch-when="choice" choice>
<!-- Render the longtext directive -->
</div>
<div ng-switch-default default>
<!-- Render the default directive -->
</div>
</div>
</div>
