how to grab values from javascript generated items?

[Eric Layman]

HI,

Im on dotnet 1.1

I've generated extra checkboxes, textboxes via client side javascript:

eg:
var inputElement = document.createElement('input');

inputElement.setAttribute('type', 'radio');...

inputElement.setAttribute('id', 'xx');

....

How do i capture these values via server side?

Pls advise.

Thanks

I don't believe you can via server side.

What you can do is create these elements serverside. Create a
placeholder on your page where you would like to insert the elements
and use the following code.

protected void addItems() {
TextBox t = new TextBox();
t.id = "myID";
Placeholder.Controls.Add(t);
}

protected void getItems() {
string s = myID.text;
}

Hope this helps.

var el = document.createElement('input');
el.type='hidden';
el.value = someValue;
el.id='myEl';
theForm.appendChild(el);
....!
Then you can do (server side) stuff like:
string tmp = Request.Params['myEl'];

But in general terms you really shouldn't DO this...!!

you also need to set the postback name

el.name = 'myEl';

Hi Thomas,

Thanks for the reply.

May I know why not? Sometimes they may be instances which we may have to
generate extra table rows or mayb extra textboxes on the fly.

Im curious whether dotnet catered for these situations and perhaps there's a
nice built in widget to do the validations for these on the fly controls! =)
