Shopping cart problems: popup window blank, products being replaced

[localp]

i am creating a shopping cart for a project..

i have come across few problems where i couldn't find a satisfiable solution .

the problem in detail;;

1. in this web site there are several pages , that contains products. and when a user clicks on a product (clicks on a checkbox) the product should go to a shopping cart which is on another page or a pop up window.

2. when i select the checkbox , the present window gets updated with the product details, and the pop up window open seperately (but blank .. no items are displayed there)

3. and when i go to another page and click on a product the products i have alreadychosen gets replaced, by the new products.

i no this is not a good thing to do (i mean asking for help) , but i have tried all, to get this thing work.

i will enclose my javascript code could you be great enough to check it and tell me where i went wrong ...

code::::::::::::::;

var store= new Array();
 
    store[0]="these  are just data"; // the data are stored in these arrays
    store[1]="jau";
    store[2]="s";
    store[3]="jr";
    store[4]="shiiii";
    store[5]="jpoler";   
    store[6]="hhddfl";
    store[7]="jmaddddddder";
function testButton (form){
 window.open ("pl.html","mywindow","menubar=1,resizable=1,width=350,height=250");
window.write ("<table border = \"1\"" + "width = \"100\">");
       window.write ("<thread> <th width = \"100\"" + "align = \"left\"> Count<th align = \"left\">" + "Frequency</th></thread><tbody>");
 
    for (var sha = 0;sha < 100; sha++) {
 
        if (form.rad[sha].checked)
        {                    // the array is called so the data is displayed
            //store=sha;
           window.write ("<tr><td>" + store[sha] +"</td><td>"+ sha + "</td></tr>");
        }
    }
    window.write ("</tbody</table>>");
}
 

and this is how i call the product from a submit button ( or even from the check box)
[html]
<input type="button" value="hi" onClick="document.testform.submit();testButton(thi s.form)"/>
[/html]

You have a number of problems with your code.

You're submitting the form and then trying to open a popup.

Secondly, you're not using window.open() properly. See this link.

Thirdly, look at the proper HTML to use for a table.

Also window.write should be replaced by win.document.write where win is a reference to the window. You're already opening a file and then trying to write to it. That will also cause problems.

this is the javascript file ::: i have done some modifications here ... if i remove the comment below i will get a lot of popup windows open .. i want to avoid it . and make the content display on it ..


for the once who is not getting what i'm trying to do -

i am trying to create a shopping cart application here using javascript ..
when the user clicks on the purchaise button the details should be submitted to the cart. and thats why i am using a pop up window.

there is another problem, when i select an item from one page it gets displayed, then when i go to another page and select another item, the items that i selected in the 2nd page replaces the items in the 1 st page .. it simply does not get appended .. so i want a solution for this also ...

can some one please alter the code for me .. i am completely lost on this ..

Which is why I've now merged the threads. Please do not double-post your questions. Keeping to one thread makes it easier to answer.

Welcome to Bytes! Since you're new, have a quick look at the posting guidelines. One of these is that code is posted in code tags. Thanks!

Let's try and deal with the problems one at a time.

When using window.open() to open a blank file to write to, use something like this:

function testButton (form){
var win = window.open('','someName');
win.document.write("<table border = '1' width = '100'>");
 

There's no 'thread' tag unless you meant a thead tag. Does that make an improvement?
