编写自定义 JSF 标签

发布于 2024-08-04 05:02:26 字数 599 浏览 2 评论 0原文

我正在尝试编写一个自定义标签。我可以写属性；但是，我在编写innerHTML部分时遇到困难：

<span class="required">*</span>

我可以写：

writer.startElement("span", component);
writer.writeAttribute("class", "required", "class");
writer.endElement("span");

如何编写*？

这是一个简单的示例，本质上，我想包装一些其他 JSF 组件来简化 xhtml 文件中的内容。

谢谢，沃尔特

I am trying to write a custom tag. I can write attributes; however, I'm having difficulty writing the innerHTML part:

<span class="required">*</span>

I can write:

writer.startElement("span", component);
writer.writeAttribute("class", "required", "class");
writer.endElement("span");

How do I write the *?

This is a simple example, essentially, I would like to wrap some other JSF components to simplify what goes into my xhtml file.

Thanks,
Walter

正如 digitalross 所解释的，您可以简单地编写文本：

writer.startElement("span", component);
writer.writeAttribute("class", "required", "class");
writer.writeText("*");
writer.endElement("span");

如果您需要包含其他 HTML 标记（而不是文本）：

writer.startElement("span", component);
writer.writeAttribute("class", "required", "class");
writer.startElement("xxx", component);
...
writer.endElement("xxx");
writer.endElement("span");

As explained by digitalross, you can simply write text:

writer.startElement("span", component);
writer.writeAttribute("class", "required", "class");
writer.writeText("*");
writer.endElement("span");

If you need to include another HTML tags (instead of text):

writer.startElement("span", component);
writer.writeAttribute("class", "required", "class");
writer.startElement("xxx", component);
...
writer.endElement("xxx");
writer.endElement("span");
