如何使用asp.net viewstate使用javascript

Question

I have UL in my page, and it is empty. I start populating it with LI using javascript.

How can I use this newly added dynamic data in the asp.net in the postback phase?

that is because my submit button is asp.net control. I do not want to use JS POST.

thanks

Answer 1

LI is not transferred over POST. Only elements of form: INPUT (text, hidden...), OPTIONS, are passed. So the simplest way is create hidden field
<input type='hidden' name='myData' id='myData' ...

and at ASP.net side access just created control by

HttpRequest request = HttpContext.Current.Request;
String value = request.Form["myData"]

I've done this sort of thing in the past by populating a hidden field with the dynamic data to be posted back, you could either -

• Fire a JavaScript event before postback that parsed the data out of the UL into a hidden field

or

• Update the hidden field as you update the contents of the UL
