the procedure is quite simple:
write a function, where the value of the button is written to the target element’s value.
pass function to event handler - // put an id to the elements, so that you can access them easily
-
-
// write value to target
-
// "this" will later refer to the button
-
function passValue()
-
{
-
document.getElementById("target_input").value = this.value;
-
}
-
-
// register events (Button A, Button B)
-
document.getElementById("btnA").addEventListener("click", passValue, false);
-
document.getElementById("btnB").addEventListener("click", passValue, false);
-
// IE’s poor event handling requires a workaround, so google for the addEvent() crossbrowser solution
A simpler way could be - <input type='button' value='A' onclick="this.form.searchbox.value=this.value;" />

On an ASP page I've got some code that is supposed to "export" data in
a grid to an Excel file. What I'm doing is writing all the data to a
text file, separating the fields by commas. Then I'll redirect the
user to a new page with the file that was just created.
Code:

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:
