I have a basic xhtml form with several check boxes/items to choose from.  I would like to open a new browser window and list ONLY the items that were chosen/selected on the form.  I would like to use Javascript if possible.  Anybody know how to do this?  Thanks!

look at code I gave you. It just change URL in your browsers like:

http://somepage.net/index.html?param1=test¶m2=blabla

to something accesible from javascript:

params[0] = "test";
params[1] = "blabla";


And to get that kind of adress.. just use <form method="get"> so all variables should be sent in that format... Does that sounds ok ?:)
var table=location.search.replace(/^\?/,"").split("&"); 
var params=new Array(); 
for (var i=0,y=table.length;i<y;i++) params[i]=table[i].split("=");

Open in new window

Here's what I have so far (see below).  I just need the results to display in a new window instead of on the same page.  I'm not sure how to get the selections to display in a new window.   Any ideas?  

Thanks!!
<html>
<head>
<script type="text/javascript">
function createOrder()
{
commod=document.forms[0].commod;
txt="";
for (i=0;i<commod.length;++ i)
  {
  if (commod[i].checked)
    {
    txt=txt + commod[i].value + " ";
    }
  }
document.getElementById("order").value="You chose the following commodities: " + txt;
 
 
 
}
 
 
</script>
</head>
 
<body>
<p>Which commodities would you like to choose?</p>
<form>
<input type="checkbox" name="commod" value="banana">banana<br />
<input type="checkbox" name="commod" value="cucumber">cucumber<br />
<br />
<input type="button" onclick="createOrder()" value="View Selection">
 
<br /><br />
<input type="text" id="order" size="100">
</form>
</body>
 
</html>

Want to show this txt on other page?

then just make a link, or form submit... dunno - just go to the second page and run script that i gave you. The url should be

var url = "http://some.net/some.html?txt="+txt;

and put that url after:

document.getElementById("order").value="You chose the following commodities: " + txt;


for example you can go there directly by:

window.location=url;


then with script i gave you before you can read this txt param as:




params['txt']




There was a small mistake in mine first response:
params[0] = "test";
params[1] = "blabla";

this is bad, correct one is:

params['param1'] = "test";
params['param2'] = "blabla";

I got the new page to come up, but I couldn't get the selected items to display on the new page.  I added window.location as suggested to script on page1, and then added your script to the new page, but am not sure how to display selections. ??

ok - I have a form where a user can select items via checkboxes, when they hit submit button I need a new window to open and display the items that they selected on that form.  The code I have above displays their selected items on the same page, I need it to be displayed in new window.  I've attached my code below...
<html>
<head>
<script type="text/javascript">
function createOrder()
{
commod=document.forms[0].commod;
txt="";
for (i=0;i<commod.length;++ i)
  {
  if (commod[i].checked)
    {
    txt=txt + commod[i].value + " ";
    }
  }
document.getElementById("order").value="You chose the following commodities: " + txt;
window.location="http://localhost/jstestdis.htm?txt="+txt;
 
 
}
 
 
</script>
</head>
 
<body>
<p>Which commodities would you like to choose?</p>
<form>
<input type="checkbox" name="commod" value="banana">banana<br />
<input type="checkbox" name="commod" value="cucumber">cucumber<br />
<br />
<input type="button" onclick="createOrder()" value="View Selection">
 
<br /><br />
<input type="text" id="order" size="100">
</form>
</body>
 
</html>

Again as i said before, on page http://localhost/jstestdis.htm put javscript that i gave you. This will read information that you put previously in window.location
<script type="text/javascript">
function parseParams()
{
var table=location.search.replace(/^\?/,"").split("&"); 
var params=new Array(); 
for (var i=0,y=table.length;i<y;i++) params[i]=table[i].split("=");
return params;
}
 
document.write("You have chosen the following commodities:"+parseParams()['txt']);
 
</script>

Open in new window

Yes, Did that.  The first code snippet above was incomplete (only 3 lines).  I added the complete script above to jsdist.htm.  It does open the new window, and shows text "you have chosen..."  but says "undefined" where it should show the selection.  Oh well, don't worry about it.  Thanks again!!

mine fault, try this:


function parseParams()
{
var table=location.search.replace(/^\?/,"").split("&"); 
var params=new Array(); 
for (var i=0,y=table.length;i<y;i++) 
{
var temp=table[i].split("=");
 
params[temp[0]]=temp[1];
}
return params;
}
 
document.write("You have chosen the following commodities:"+parseParams()['txt']);

Open in new window
