Javascript to C#

[DFDavis]

I have a bunch of dynamically created checkboxes that I add to the a
label in the html through my C# code. Then I also have a javascript
function that goes through and identifies which checkboxes are checked
when the user clicks on the submit button. My question now is, how
would I go about getting the list of checked boxes back to my C#
program? I am not sure if you can pass an array from javascript to C#
or even exactly how you create an array in javascript. However, my
code for finding the checked boxes is like this :

function Select(x){
l=document.form1;
n=l.elements.length;
var i=0;
for(i=0;i<n;i++){
if(l.elements[i].type=='checkbox' &&
l.elements[i].checked){
// Add element value to the array
}
}
}

any help would be greatly appreciated.

Thanks,
Dan

Hello DFDavis,

Start from here http://groups.google.com/groups?q=do...vascript+array

as one solution is to create the string that represent your array (smth like
serialized array), put that string into hidden asp.net textbox and use form.submit()
to send data to server

DI have a bunch of dynamically created checkboxes that I add to the a
Dlabel in the html through my C# code. Then I also have a javascript
Dfunction that goes through and identifies which checkboxes are
Dchecked when the user clicks on the submit button. My question now
Dis, how would I go about getting the list of checked boxes back to my
DC# program? I am not sure if you can pass an array from javascript to
DC# or even exactly how you create an array in javascript. However,
Dmy code for finding the checked boxes is like this :
D>
Dfunction Select(x){
Dl=document.form1;
Dn=l.elements.length;
Dvar i=0;
Dfor(i=0;i<n;i++){
Dif(l.elements[i].type=='checkbox' &&
Dl.elements[i].checked){
D// Add element value to the array
D}
D}
D}
Dany help would be greatly appreciated.

If your checkboxes are inside a FORM field, then when the page is posted,
they will all be in the Request.Form collection.
