Subject: Re: Why submit didn't support param
To: Martin Gainty <mgai...@hotmail.com>
Hi, Gainty
Thanks!
But there is a problem in my case.
Like I have 10 textfields generated by iterator. user can input and remove
any one of them by a link/button near each one of them.
##############################The link
way#######################################
<s:iterator value="requestTypeList" status="rtStatus">
<tr>
<td colspan=2 class="fieldCaption">
<s:text
name="Field%{#rtStatus.index+1}" />
<s:textfield
name="Field%{#rtStatus.index+1}" />
<a href='<s:url action="RemoveTextField"
><s:param name="fieldid" value="%{#rtStatus.index}" />' >Remove</a>
</td>
</tr>
</s:iterator>
##############################End of the link
way#######################################
If the remove is a link. the iterator can remove the textfield I specified.
But the users' input in other 9 textfields will get lost after the
returning!(requestTypeList will be empty)
Submit however, Can send all the user input along to struts, so those
value can be maintained after the returning. But so far it seems there is no
way to send the param along with submit .:-(
