How to pass parameters using dmf:link

vsoman1984

Hi All,

I have the following piece of code inside my JSP.

  <tr> <td colspan="2"> <TABLE BORDER=2> for ( int i = 0; i < MyDashboard.ptSummary.length; i++ ) { %> <%<TR> <% if(MyDashboard.ptSummary[i].getID()!= "") {%> <TD><%= MyDashboard.ptSummary[i].getID() %></TD> <!-- **Want to convert this to a link**--><TD><%= MyDashboard.ptSummary[i].getDescription() %></TD> <%} %> </TR> <%}%></TABLE> </td> </tr>

This renders a table with two columns namely ProjectID and Project Description.These are obtained from the property ptSummary which is an array.

My aim is to convert the row entries under the Project ID column to links on whose click i could pass that particular id onto my Behaviour class.

Now i have come across an example involving dmf:link in the categorylist_thumbnail_body.jsp in the following code.

<dmf:link onclick='onClickObject' runatclient='true' datafield='object_name'>

<dmf:argument name='id' datafield='r_object_id'/>

<dmf:argument name='type' datafield='r_object_type'/>

<dmf:argument name='isFolder' datafield='isfolder'/>

</dmf:link>

My question is how can i utilize the example in categorylist_thumbnail_body.jsp. where the "datafield ='object_name' is utilized (probably from the database) to have my data coming from the java class and pass this as a parameter i.e. i need to pass <%= MyDashboard.ptSummary[i].getID() %> as a parameter when the user clicks on this link.

Looking forward for your help and support.

Thanks & Regards

Hi ,

I am in the process of creating a build wih the following changes:

  <tr> <td colspan="2"> 
<TABLE BORDER=2> for ( int i = 0; i < MyDashboard.ptSummary.length; i++ ) { %> 
<%
<TR> 
<% if(MyDashboard.ptSummary[i].getID()!= "") {%> 
<TD><dmf:link onclick='onClickPrjtId' datafield ='<%=MyDashboard.ptSummary[i].getID()%>' >
    <dmf:argument name='id' datafield ='<%=MyDashboard.ptSummary[i].getID()%>'/></dmf:link></TD>
<TD><%= MyDashboard.ptSummary[i].getDescription() %></TD> 
<%} %> 
</TR> 
<%}%>
</TABLE> </td> 
</tr>

and have the following function inside my MyDashboard.java

public void onClickPrjtId(Control control, ArgumentList args){String strId = args.get("id");System.out.println("This is the value of the clicked Project " + strId);}

Is this a correct approach wherin i could get the value of the clicked project ID link in my Sysout?

Thanks & Regards

Hi All,

The following is the result of the trial i carried out by passing arguments using dmf:link in the above post. I am geting the following Warning on the link .The number seen wiz 42128 is one of the valid Project ID's (not to be confused to be some Error ID : ) ) .And as i click on the link the function "onClickPrjtId" i am getting no value inside the Sysout i.e. only the following text is seen :"This is the selected prjt ID" on my Tomcat console

Could you please suggest a solution and point me to the place where i am geting it wrong.

Thanks & Regards

Hi Friends

I have been able to overcome the error by the following code in my JSP:

I used "label" instead of datafield and passed the value of name onto my Java class.

<TR>
<% if(MyDashboard.ptSummary[i].getID()!= "") {%>
<TD><dmf:link onclick='onClickPrjtId' label ='<%=MyDashboard.ptSummary[i].getID()%>' >
<dmf:argument  name='id' value ='<%=MyDashboard.ptSummary[i].getID()%>'/></dmf:link></TD>
<TD><%=MyDashboard.ptSummary[i].getDescription() %></TD>
<%} %>
</TR>

I hope i followed a valid appraoch to overcome my predicament.Hope this helps others too.

Thanks & Regards
