html:Submit with more properties

[Andrea Biraghi]

Hi,

I have a table with several row. For each row i need to insert a submit button to delete row.

Problem: I used the submit property to define dispatch value (method name inside the action)
How can I pass to action selected row's number id?


JSP:

<logic:iterate id="place" name="details" property="info.places" indexId="indexList">
....
<html:submit property="dispatch" styleClass="<%= buttonStyle %>">
<bean:message key="button.delete"/>
</html:submit>
</logic:iterate>


ACTION (I use LookupDispatchAction):
....
public ActionForward delete(ActionMapping mapping, ActionForm form, HttpServletRequest req, HttpServletResponse res) throws IOException, ServletException {

String indexId = req.getParameter("indexList"); ??? I need indexId parameter ???
...
delete record on DB
}

P.S. I can't use JavaScript

Thanks

Andrea

You can pass it as an "query string", like
http://host/YourAction.do?rowid=3

OR
Pass row id as a hidden attribute.
JSP:

 <logic:iterate id="place" name="details" property="info.places" indexId="[b]indexList[/b]">
  ....  <html:hidden name="rowid" value="indexId"/> // pass row id
        <html:submit property="dispatch" styleClass="<%= buttonStyle %>">
           <bean:message key="button.delete"/>
        </html:submit>
 </logic:iterate>

[Please this is the approach not complete code ]

Hi Sagar,
thank you for your reply but it doesn't work.

1st solution: I need to submit form. I can't use link with attributes

2nd solution: rowid is the same for every row. This value isn't dynamic! "rowid = last indexList"

Here's my code:

<logic:iterate id="place" name="details" property="info.places" indexId="indexList">  
  ....  <html:hidden property="rowid" value="${indexList}"/>
        <html:submit property="dispatch" styleClass="<%= buttonStyle %>">  
           <bean:message key="button.delete"/>  
        </html:submit>  
 </logic:iterate>     
 

I tried to use indexed attribute but nothing.

Any idea?

Usually, the delete action requires a single attribute, e.g to delete "person/user" record I'll submit person id/user id and delete that row from db, If this is what you're doing then you can pass that id using link.

I don't know your html form or which property you're submitting. But to pass "id" through link, I'll use html:link tag instead of html:submit.
like

<logic:iterate id="place" name="details" property="info.places" indexId="indexList">  
  ....  <html:hidden property="rowid" value="${indexList}"/>
        <html:link action="YourDisptachActionForDelete" styleClass="<%= buttonStyle %>">
         Delete
        </html:link>
           <bean:message key="button.delete"/>  
        </html:submit>  
 </logic:iterate>

Sorry for that.

Finally, you need to pass an "request" attribute when you call delete action, either pass using "query string" or hidden request parameter, concentrate on that, you will get your answer.

I can't use html:link because I need to submit form values

And which value you're submitting, As I quote earlier, to DELETE, you hardly require a FORM to submit. so whats your need ?

And If you still want to SUBMIT a FORM, a hidden ID can be passed any time OR If I'm not getting your requirement then read this.
