inserting links into dynamic content

[Rob Dennett <ro...@tmit1.org>]

I have a situation where text from the database needs to be inserted from the database.  I want to be able to parse this text for words that appear in a glossary, and if so, render a link around them that opens a new window containing the definition for the glossary term.  Since you can’t add components at run time, it seems that the only way to do it is to have a component that uses IMarkupWriter to dynamically add an anchor tag around the text with the same href that tapestry would generate if you were using a component.  Is this correct or is there a simpler way to do it?

 

As I finished typing this, I thought of a more Tapestry-like way and I would like to share it.  Split the text into a collection of words.   Then do something like this:

 

<span jwcid=”@For”  value=”word”  source=”words”>

            <span jwcid=”@If” condition=”ognl:inGlossary(word)”>

                        <a href=”#” jwcid=”@PopupLink”><span jwcid=”@Insert” value=”ognl:word”/></a>

                        <span jwcid=”@Else”><span jwcid=”@Insert” value=”ognl:word”/></span>

            </span>

</span>

 

I have left adding in spaces and punctuation marks as an exercise for the reader <span jwcid=”@Grin”/>

 

For what it’s worth,

Rob

Look for a thread called "creating a link around a part of a sentance". 
The last posting contains a solution.
