populating webpage elements with contents of an iframe

P: n/a
Hi friends,

I am developing a web application using Jsp and JS.

I have a main Jsp page(Jsp1).Inside it I have an iframe having an Html-
table which is created dynamically and contains all records from the
backend-table . For creating this dynamic table I've used another
Jsp(Jsp2) and in Jsp1 I say:
<iframe id = "I1" src="Jsp2.jsp" width=320 scrolling="yes">

Now I have links on every row of the table and the link is used to
select a particular row for modifying it.User can select one row at a
time.
For eg on clicking a link on the name 'Mr.Jack Brown' from the table
in the iframe I need that the info of 'Jack Brown' be populated into
the corresponding fields of the main Jsp(Jsp 1) i.e in 'Student Name-
textbox' it should show 'Mr.Jack Brown', in 'Batch ID-textbox' it
should show '1' etc .

Here's a snapshot of Jsp1:-

Is it possible that I can actually populate the elements of the parent
window with data(fields) from the table present in the iframe or is
there any other way of achieving this?

Any suggestions much appreciated !

First of all i would suggest moving away from iframes but since you
have them. Also I am not a jsp expert by any means. I think the answer
you are looking for is displayed in my example below I will recap to
make sure I understand.

jsp1.jsp:
<html>
<body>
<iframe src=jsp2.jsp></iframe>
</body>
</html>

jsp2.jsp

<a href="jsp1.jsp?id= + <%jspcode to identy record%>"
target="_parent">Mr. Jack Brown</a>

let me know if that makes since!

Hi and Thanks for your reply, well I gave up the idea of working with
iframe and now I'm creating&displaying a dynamic table on Jsp1 itself,
also I discarded the idea of using links; now what I have is as
below:-

The dynamic table is placed inside a <divon Jsp1 and it has vertical
scrollbar. Each row in this table has a radio button associated with
it which is used to select a particular row for modifying it.User can
select a single row at a time.So now I want that if I select the radio
button on say the 3rd row then the cell-contents of the third row
should be populated in the corresponding textfields of Jsp1.

I am totally clueless as to how to determine which row it is that has
its radio button clicked and how to retrieve individual cell values of
the table and set them as text in the textboxes on Jsp1?! Any ideas?

Your killin' me! Just kidding. Doesn't sound to difficult.

It looks like you will create your table with jsp and the radio on
creation should the value should be declared. So I image it would look
something like this:
<body>
<form id="form1" name="form1" method="get" action="JSP1.jsp">
<table>
<%jsp to start loop to create radio button for each record%>
<tr><td>
<input type="radio" name="id" value="<%jsp code for ID%>"
onChange="javascript:document.form1.submit();" />
</td><td><%JSP to write Mr. Jack Brown</td>
</tr>
<%jsp for end of loop to go to next record%>
</table>
</form>
you should see that the form on submit to the same page. What will
happen is when radio button is selected i will auto submit the form to
the same page with the address being "JSP1.jsp?id=1234" or whatever
your id number is. I know php so i will just write out what I would do
for that to work.

Check to so if url param is set.
if set query database with id set to url param
fillin value of jsp1 form with those values.

Hope this helps and makes since feel free to ask any questions.

Hi Adambrz
Thanks for your time and response,

A snapshot of my webpage is located here:-
http://www.dynamicdrive.com/forums/attachment.php?
attachmentid=758&d=1170187911

It's a Jsp and on it I have a table (say T1) which is created
dynamically and contains all the backend-table's records as rows. I am
creating this dynamic table inside a <divon Jsp1 and using a Jsp-
scriptlet to get the backend data into the table. I have set a
vertical scrollbar on the <divsuch that user can see 4 rows of T1 at
a time. Each row in T1 has a radio button associated with it which is
used to select a particular row for modifying it. User can select a
single row at a time.

The requirement is that if I select the radio button on any row then
the cell-contents of that row should be populated in the corresponding
textfields of Jsp1.

For eg: if the user clicks the radio of the 3rd row then 'Student Name-
textfield' should show "Mr.Jonathan Brown"; 'Batch-ID-textfield'
should show "1" etc i.e. every textfield should be populated with the
corresponding cell value of the row.

I have grouped the radio-buttons and the group-name is "Group" but I
am totally clueless as to how to determine which row it is that has
its radio clicked and how to retrieve individual cell values of the
table and set them as text in the textfields of Jsp1?!

This is somewhat how my entire webpage(JSP) looks like in brief:-
