pass array object of child window references from client side to server side

you can do it using Cookie ...... but the problem is you can't store Array in Cookie ..... you have to store it as String

<body onunload = "getChilds('htmHdnChild')">

function setChilds(HdnID)
{
alert("in set child");
var hdnCtrl = document.all(HdnID);
if (hdnCtrl!=null)
{
myChild = hdnCtrl;
alert(myChild.length);
}
}

function getChilds(HdnID)
{
//alert("in Get child");

How can you assign an array to a hidden field?
It is not possible.
You can store the values in a hidden field something like this.

Expand|Select|Wrap|Line Numbers

<input type="hidden" id = "hdnID">

Expand|Select|Wrap|Line Numbers

 
var hdn = document.getElementById('hdnID');

var array_values = "";

var separator = "/*the separator character so that it does not occur in your array values*/";

var array_obj = /*this is your array object*/ ;

for(var i = 0;i<array_obj.length-1;i++) array_values += array_obj[i] + separator;

array_values += array_obj[i];

/*now write a code for retrieving the values from your hidden field ...using String.split method*/

hey are you looking for server side script ...?
but you have first send it to ..... server ............then you can store it.
i think you can't directly send an array to server.

Dear All,

i am having a parent window
say parent.aspx
here i am creating child windows in javascript
like this

Expand|Select|Wrap|Line Numbers

 
var myChild = new Array();
 
function MenuPopUp(url,width,height,left,top)

    {

        if (width == 0)//code to close all the open windows

        {
 
            var len=0;

            for (i=0; i<myChild.length; i++) 

                {

                if (myChild[i].closed == false)

                    len = len+1;

                    //alert(myChild[i])

                }

            //alert(len);
 
            if (len >0) {
 
            if (len == 1)

            {

                alert(" Switch from Company - Closing the open Window ")    ;

            }

            else

            {

                alert(" Switch from Company - Closing all "+ len +" open Windows ")    ;

            }
 
            for (i=0; i<len; i++) 

                {

                if (myChild[i].closed == false)

                myChild[i].close();

                }

            }

            relocate(url,"s_company_name");
 
        }

        else// code open newe window and assign to the array 

        {

            var Children ;

            Children = myChild.length;

            //alert(Children);

            myChild[Children] = window.open(url,"","width=" + width +",height=" + height +",top=" + top + ",left=" + left + ",toolbar=no,menubar=no,scrollbars=yes,resizable=yes,location=no,directories=no,status=no");

        }

    }

this function will open a new window in else part and closes the existing windows in the if part

and for each window i am opening i am referencing/assigning it[window] to a array object

so while doing some action in the main page , i need to close the child windows , so i can directly close by looping though the array and close the windows.

but in my main page [parent] page i have implemented a page refreshing logic
according to this the page will refresh after 500 secs

so in this following scenario the certain open windows become orphan
1) opening 2 new windows at 10th sec
2) wait until the page refreshes [say 500]
3) after 500 sec open another window
4) now do the task where you need to close all the child windows
5) the already opened 2 windows left open as orphans

this is why because while refreshing the javascript variable [myChild] is being reset and all the values contained in the variable is destroyed.

the windows opened will have no reference

Question:
so now i need to pass this array object to server[on unload event] and save the object in the session variable and retrive and restoring it to the array variable while the page loads again
so i may be having reference to all the child windows opened..

please give me solution

Thanks,
Raj

hi ...

i think that will not work the way you think, i'm quite sure that you cannot store window-references at the server since that are client-side objects ... but you have other possibilities:

1. instead of refreshing the entire page you may use an ajax-call and update only the relevant parts of your page

2. use a frameset with a frame for your main page and one with 0px height and width, where you may store your references during the app-runtime

kind regards

Thanks gits,
so there is no way for passing the array objects from client side to server side

Normal arrays with simple data such as numbers and strings, yes, but references to child windows, no.

Why not use Ajax, frames or iframes as gits has suggested?
