Re: Highlight some words in the markup content
Perhaps you could use a jQuery plugin to do this? Something like [1] -
although this is just the first Google result that came up for me. I have
not tested this.

Re: Highlight some words in the markup content
I'd be interested to know if anyone else is using this technique for search
highlighting with a DataTable.
http://pastebin.com/m5446797d
The data in my grid may contain HTML, so that makes it considerably more
complicated (my first attempt didn't address this problem). I'd love to
know if someone else has a better/simpler way, although this does appear to
work fine, it took a day to come up with.
In general, I kind of like the idea of separating this concern from the
model, whose purpose is just to get the data, and think of this search
highlighting as more of a decorator that applies to the entire grid rather
than any particular column, since I've got several PropertyColumn subclasses
(LinkPropertyColumn, ImagePropertyColumn, NonEscapedHTMLPropertyColumn,
...etc).
Hope this helps someone else.
Thanks,
-- Jim.

Re: Highlight some words in the markup content
I've got a few embellishments to that idea that others might enjoy. These
include the ability to use on non-string properties, and caching the last
compiled pattern (maybe uses a bit less CPU than replaceAll each time).
protected static class HighlightingModel extends LoadableDetachableModel
{
private static final long serialVersionUID = 1L;
private transient IModel text;
private transient IModel searchWord;
private transient Pattern lastp;
private transient String lastSearch;
HighlightingModel(IModel text, IModel searchWord) {
this.text = text;
this.searchWord = searchWord;
}
@Override
protected String load() {
String srch = (String)searchWord.getObject();
Object object = text.getObject();
String txt = "";
if (object != null) {
IConverter converter =
Application.get().getConverterLocator().getConverter(object.getClass());
txt = converter.convertToString(object,
Session.get().getLocale());
}
if (srch != null) {
Pattern p = null;
if (lastp != null && srch.equals(lastSearch) )
p = lastp;
else {
try {
p = Pattern.compile(srch, Pattern.CASE_INSENSITIVE);
} catch (PatternSyntaxException e) {
if (e.getIndex()>-1) {
srch = srch.substring(0, e.getIndex());
try {
p = Pattern.compile(srch,
Pattern.CASE_INSENSITIVE);
} catch (Exception e2) {
srch = null;
}
} else
srch = null;
}
}
if (p != null) {
Matcher m = p.matcher(txt);
return m.replaceFirst("$0");
}
}
return txt;
}
@Override
protected void onDetach() {
super.onDetach();
text = null;
searchWord = null;
}
}

Re: Highlight some words in the markup content
Thanks all. The first tests work fine now, still need to handle the ignore-case searching... Is there anybody else interested in this feature? Then I will try to prepare the IResponseFilter implementation for public viewing/integration in Wicket. as far as i know the response filter runs within the request cycle and request cycle has metadata facility, so We already make use of RequestCycle.get(), but if you don't work on Wicket the full day like you, then one forgets such secrets. -- Cheers, Tom Igor Vaynberg wrote: as far as i know the response filter runs within the request cycle and request cycle has metadata facility, so -igor On Wed, Oct 15, 2008 at 10:07 AM, Thomas Singer <[EMAIL PROTECTED]> wrote: Thanks.

Re: Highlight some words in the markup content
If you are displaying search results dynamically, and it's not part of your
static markup, you can also do something like this:
class HighlightingModel extends LoadableDetachableModel {
private transient IModel text;
private transient IModel searchWord;
HighlightingModel(IModel text, IModel
searchWord) {
this.text = text;
this.searchWord = searchWord;
}
@Override
protected String load() {
return text.getObject().replaceAll(searchWord.getObject(),
"" + searchWord.getObject() + "");
}
@Override
protected void onDetach() {
super.onDetach();
text = null;
searchWord = null;
}
}
IModel resultDescription = new HighlightingModel(new
PropertyModel(someObject, "someProperty"), new PropertyModel(searchQuery,
"searchTerm"));
