Modify element attribute, preserve content
Hello, I have the following case which I do not know how to handle with Wicket: I have an element (specifically it is an a href=.../a link) for which I need to generate an attribute's value dynamically (specifically, I need to set the href attribute at runtime), but I need to preserve the static content of the page. For example, my HTML file is: a wicket:id=myTargetspan class=x/spansome static text/a What do I have to do to produce: a href=dynamically generated targetspan class=x/spansome static text/a So far, I've always replaced the entire content of an element with that generated by some wicket component, but this is the first time I've needed to filter part of the DOM and target something very specific in the middle of the tree, without affecting the rest of the tree... - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Modify element attribute, preserve content
Use a WebMarkupContainer and add a SimpleAttributeModifier behavior to it. It will not touch the contents of the tag it's attached to, leaving your own html as it is.

Or, come to think of it, since you want to generate a href yourself on a link tag, use ExternalLink http://wicket.apache.org/apidocs/1.4/org/apache/wicket/markup/html/link/ExternalLink.html. Since it's a WebMarkupContainer underneath it will leave whatever is inside your a-tag intact.
