I am trying to POST dynamic form elements added using javascript but unable to do so. The elements are being shown when I add them but don't see anything on the test.php page.
I have been trying to figure out the issue but in vain. I also used Firebug to inspect the DOM elements but it looked fine. Please help
Here is my code: - <html>
-
<head>
-
<script type="text/javascript">
-
-
function add() {
-
-
//Create an input type dynamically.
-
var element1 = document.createElement("input");
-
var element2 = document.createElement("input");
-
var newdiv = document.createElement("button");
-
var space = document.createElement("div");
-
//Assign different attributes to the element.
-
-
element1.setAttribute("type", "text");
-
element2.setAttribute("type", "text");
-
//newdiv.setAttribute("type", "button");
-
//element.setAttribute("value", type);
-
//element.setAttribute("name", type);
-
var numi = document.getElementById('theValue');
-
var num = (document.getElementById('theValue').value -1)+ 2;
-
numi.value = num;
-
-
var area = document.getElementById('area');
-
-
var divIdName1 = 'name'+num;
-
var divIdName2 = 'amount'+num;
-
var divIdName3 = 'button'+num;
-
-
element1.setAttribute('id',divIdName1);
-
element2.setAttribute('id',divIdName2);
-
newdiv.setAttribute('id',divIdName3);
-
-
element1.setAttribute('value',divIdName1);
-
element2.setAttribute('value',divIdName2);
-
newdiv.setAttribute('value','harsh');
-
-
// element2.setAttribute('id', );
-
-
//Append the element in page (in span).
-
space.innerHTML='<br />';
-
newdiv.onclick = function() {
-
//document.write(divIdName1);
-
var olddiv = document.getElementById(divIdName1);
-
area.removeChild(olddiv);
-
olddiv = document.getElementById(divIdName2);
-
area.removeChild(olddiv);
-
olddiv = document.getElementById(divIdName3);
-
area.removeChild(olddiv);
-
area.removeChild(space);
-
}
-
-
-
-
area.appendChild(element1);
-
area.appendChild(element2);
-
area.appendChild(newdiv);
-
area.appendChild(space);
-
}
-
</script>

Elements will need a "name" attribute to be available in your server-side script.

Hello,
I am trying to generate a dynamic form at runtime and would like to do it
using "<asp: ..." form elements as follows
Build up the string that is placed somewhere in the HTML code the same way
like regular input fields can.
strForm = "<form name=""myForm"" runat=""server"">" & vbCrLf
strForm += "<asp:button name=""myName"" .... runat=""server"" />" & vbCrLf

People,
Here's my situation:
1. I have a web browser component that does not support Javascript
(well it does, but we've disabled it)
2. I have to display some HTML in it, where the user has a link titled
"Hide|Show Options" that can hide/show a particular section of the
HTML.
I have not found a way to achieve it without using Javascript or any
other scripting language.

Hi,
I have a Javascript function that creates a number of checkboxes dynamically using document.createElement. The checkboxes are created fine but even when they are checked they don't appear in $_POST in Internet Explorer. The same code works fine in Firefox and I can get the details of the checkboxes that are checked. Does anyone know of any problems with checkboxes in IE?
Thanks,
Sean

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
