How can I send back an argumet with "onClick"?
<a href=test.php onClick="checkL ink ('Gallon')" > 1 Gallon</a>
function checkLink(a)
{
return (a+3)
}
When the user click on the word "Gallon"
I want the value "Gallon" to go to session_var 2 14794
You can't do that directly. You'll have to call a PHP script for that,
somehow or another.. (or use cookies instead, but thats pretty
complecated and might not help you that much)
You might wanna do the following for example:
<a href=# onClick="checkL ink('Gallon');" > 1 Gallon</a>
function checkLink(s) {
location.href=' test.php?checkl ink='+escape(s) ;
}
This will send checklink as parameter to test.php. Now in PHP you can
retrieve that values by getting get get values... depending on your PHP
configuration either the variable $checklink exists or you'll have to do
with with the (I thought, but I'm not totally sure) $_GET['checklink']
variable.
There are serveral other solutions. For example, you could open a popup
window, and process the value there, or you could build a forward
page... like:
location.href=' forward.php?che cklink='
+escape(s)+'&li nk='+unescape(l ink);
forward.php would then first process the value of checklink and then
forward to $link (see HTTP response codes, and the PHP header() function)
Good luck,
Vincent
In article <20************ *************** @mb-m28.aol.com>, ga*****@aol.com enlightened us with... How can I send back an argumet with "onClick"?
You assign the return value to a variable.
onClick="var a=checkLink('Ga llon');" <a href=test.php onClick="checkL ink ('Gallon')" > 1 Gallon</a> function checkLink(a) { return (a+3) } When the user click on the word "Gallon" I want the value "Gallon" to go to session_var
If that's a real session variable, you can't do that. Session variables
are interpreted on the server. Javascript runs on the client. By the
time the JS runs, the server is done processing the request and has sent
it to the client.

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.
