2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex17/dowiframe.htm

3) Describe problem:

hi, gurus,

i have a page which has two frames, left.jsp and right.jsp.

in the left.jsp, i have 4 links.
<a href="right.jsp?id=1 target=right">first</a><br>
<a href="right.jsp?id=2 target=right">second</a><br>
<a href="right.jsp?id=3 target=right">third</a><br>
<a href="right.jsp?id=4 target=right">fourth</a><br>

and in the right.jsp, i have iframes,
<iframe id="testiframe1" src = right1.jsp name="first" style="display:<%=(request.getParameter("id").equals("1"))?"":"none"%>" height="100%" width="100%" frameborder="0" scrolling="auto"></iframe>

<iframe id="testiframe2" src = right2.jsp name="second" style="display:<%=(request.getParameter("id").equals("2"))?"":"none"%>" height="100%" width="100%" frameborder="0" scrolling="auto"></iframe>

<iframe id="testiframe3" src = right3.jsp name="third" style="display:<%=(request.getParameter("id").equals("3"))?"":"none"%>" height="100%" width="100%" frameborder="0" scrolling="auto"></iframe>

<iframe id="testiframe4" src = right4.jsp name="fourth" style="display:<%=(request.getParameter("id").equals("4"))?"":"none"%>" height="100%" width="100%" frameborder="0" scrolling="auto"></iframe>

alright,
so when i open right1.jsp, there is a textarea which i can type something into it.
what i want is, if i typed something in the right1.jsp, then i open right2.jsp. and when i open back right1.jsp, the text are still there.

i heard that it can be done in iframe, but it refresh everytime i open back the right1.jsp.
is it possible to make right1.jsp to not refreshing?

thank you.

First off, this has nothing to do with the script you mention that I can see. And I think you might be confusing the server side language - jsp, with the client side language - javascript. Javascript is covered in these forums but not jsp.

There are two basic approaches to what I think you are talking about:

1) Once data has been inserted into a textarea on a page, don't reload it.

Or:

2) Recall the previously loaded data each time the page is loaded.

Javascript can do either but, since I see you are using jsp, I would think that it could do #2 above and that would be the best approach as, it would work for folks even if they had javascript disabled.

I don't know enough about jsp to advise you on specifics. A jsp forum would probably be brimming with folks that could help you though as, this is a basic operation in any server side language such as jsp, PHP, asp, etc.

thanks for replying.

i actually done something on that and it is working.
the below is the source.

<html>
<head>
<script language="Javascript">
var iframe1;
var iframe2;

function test()
{
iframe1=document.createElement("iframe");
iframe1.name="iframe1";
iframe1.style.display="";
iframe1.src="right1.html";
iframe1.height="100%";
iframe1.width="100%";
document.body.appendChild(iframe1);

iframe2=document.createElement("iframe");
iframe2.name="iframe2";
iframe2.style.display="none";
iframe2.src="right2.html";
iframe2.height="100%";
iframe2.width="100%";
document.body.appendChild(iframe2);
}

function call(id)
{
if(id=='1')
{
iframe1.style.display="";
iframe2.style.display="none";
}
else if(id=='2')
{
iframe1.style.display="none";
iframe2.style.display="";
}
}

</script>
</head>
<body onLoad="test();">
</body>
</html>

so when i call
javascript:void(call(1));
the iframe1 will come out and iframe2 will hide.

My previous problem is solved then.
but then i met another problem.

my right1.html source:

<html>
<body>
<a href="http://www.yahoo.com" target="iframe2">iframe2</a>
</body>
</html>

when i click this link, a new window is pop out and load yahoo.
I wonder why is it open in new window but not in second iframe.

thanks.
