RIOT.JS - Yield

Yield 是一种将外部 HTML 内容放入 RIOT 标签的机制。有多种方法可以实现 yield。

简单 Yield − 如果我们要替换标签中的单个占位符，则使用此机制。

<custom3Tag>
   Hello <yield/>
</custom3Tag>

<custom3Tag><b>User</b></custom3Tag>

多重 Yield − 如果我们要替换标签中的多个占位符，则使用此机制。

<custom4Tag>
   <br/><br/>
   Hello
   <yield from = "first"/>
   <br/><br/>
   Hello 
   <yield from = "second"/>
</custom4Tag>

<custom4Tag>
   <yield to = "first">User 1</yield>
   <yield to = "second">User 2</yield>
</custom4Tag>

示例

以下是完整示例。

custom3Tag.tag

<custom3Tag>
   Hello <yield/>
</custom3Tag>

custom4Tag.tag

<custom4Tag>
   <br/><br/>
   Hello
   <yield from = "first"/>
   <br/><br/>
   Hello 
   <yield from = "second"/>
</custom4Tag>

         <yield to = "second">User 2</yield>
      </custom4Tag>   
      <script src = "custom3Tag.tag" type = "riot/tag"></script>
      <script src = "custom4Tag.tag" type = "riot/tag"></script>
      <script>

         riot.mount("custom4Tag");
