Display only 100 chars of a string
Hi all.
there's a possibility inside a jsp to display only the first 100 chars
or the first 10 words of a string?
if i have a long string, can i display only the first 100 chars
directly in a jsp without modification in action or something like
that?
thanks

Re: Display only 100 chars of a string
Posted by Greg Lindholm <gr...@gmail.com>.
I have added an abbreviate() method to our base action class.
/**
* Abbreviate a string using ellipses (...).<br>
* If text is longer then len it is truncated to len characters then the
* last 3 characters are replaced with ellipses (...).
*
* @param text the string to abbreviate
* @param len the maximum length of the returned string (must be greater
* then 3)
* @return the string abbreviated with ellipses to a maximum length of
* <code>len</code>
*/
public String abbreviate(String text, int len)
{
return org.apache.commons.lang.StringUtils.abbreviate(text, len);
}
Then in the JSP I can use it like this <s:property
value="abbreviate(name,25)" />

Posted by Martin Gainty <mg...@hotmail.com>.
i couldnt get that to work either..
suggest setting the value and truncating the value to a new String variable in action class or setting the value and truncating the value to a new String variable in backing bean

In his example, the stack is searched for a property called
'description', in the new version of the tag, you probably have to
explicitly tell OGNL where to find 'description'. Try the following -
<s:property value="@java.lang.String@format('%.100s', #top.description)" />
(I think it's #top, but I could be wrong, perhaps one of the OGNL
gurus can chime in).

What have you tried so far? I sure wouldn't think the word "method"
should appear--why not just try what seems obvious, for example
"@@min(...)" or "@min(...)"?
I think I'd be more comfortable specifying the full class anyway.

Hey!
I'm of two minds regarding this... Truncating a string is really a
view-layer issue, handled (or instigated) by a designer (which is
usually us) or a design-driven process.
That said, if it's a site-wide thing--where does it belong? Maybe a
custom tag, which is kind of a compromise: the OGNL treachery is
localized (if done in OGNL), or the scriptlet, or a utility call into
the app, etc.
If I was doing it myself I'd probably just "cheat", or create a
JSP-based custom tag that wrapped it up and hid it away.

No, Jon, you are right... This belongs in the action class. Just
because OGNL lets you cheat doesn't mean you should (cue Dave jumping
in any minute). I think the OP mentioned at one point that adding this
to the action is not an option.
Also, another choice is to use JavaScript. Is the choice to abbreviate
because of bandwidth or screen real estate?

I could be wrong...
Honestly, you'd be better off adding a function to your action class
that would format a string to a specific length. It would be clearer
what was going on. Something like
public String formatString(String s, int maxLen) {
return String.format("%." + maxLen + "s", s);
}
It would also be an easy extension later if you decided that you wanted
truncated strings to end with elipses:
public String formatString(String s, int maxLen) {
if (s.length() < maxLen) {
return s;
} else {
return s.substring(0, maxLen - 3) + "...";
}

I put the abbreviate() method in the action class. It's actually in our
'base' action class so it's always available.

@Greg: do u put that code inside the bean? i can't do this.
@Jon thanks, but i've some problem with the " of the part: "%.100s"
the system found a end tag " at the first " that it encountred. i
tried to put \" but doesn't work.

That would cause an IndexOutOfBoundsException if the string was shorter
than 100 chars. Try this instead:
String.format("%.100s", s);
That would return up to 100 characters from the beginning of the string
's'.

This seems like the kind of thing that is crying out for a custom tag -- and
I don't say that lightly. I mean, a scriptlet could do it, but scriptlets
are from the devil. A custom tag would be a better solution, especially
since this is a pretty general problem.
