Listen JSP

[kramisimo]

Hallo,
ich habe eine Frage, wie kann man in JSP eine Liste Dynamische generieren, ich meine:



kann man bei diese input die name als Array definieren?
wenn ja, wie kann man diese Array setzen?

Gruss,

krami.

Erm, I'm not sure that I understood the question correctly (Babelfish isn't perfect :^D ).
I gather what you are asking is:
"If I can create a dynamic list like this:
< input type="text " name="QTY[ ] " size="5 " VALUE = " < %=warenkorb,getQTY(i)% > " >

How can I get the name to be dynamic too? "
If that is your question, then this is my answer:

One idea would just be to concatenate the name to the array value like this:
name="<%="QTY"+i%>"

But I wonder how you would then read the values in your servlet. The way I do it is like this:

< input type="text " name="QTY" size="5 " VALUE = " < %=warenkorb,getQTY(i)% > " >
Then I can get all the values that the user entered in the form of an array. like this:
String quantities = request.getParameterValues("QTY");

Hope this helps ?!

Hi !

You can create a dynamic list like this

<% for (int i=0; i < myArray.length; i++){ %>
<input type="text" name="QTY" size="5" VALUE="<%=myArray%>">
<% } %>

If you're using the same name for input-fields you get an array of values (for example in your servlet). You have no other chance then to iterate through your array, setting them individually.

Bye,
