Problem with persistent checkboxes and refresh and solution
Hi all
I just solved a problem which appeared on my cart page, and perhaps you're
interested as well.
We have a special programme for our customers called Joker, and the customer
should be able to check a checkbox and then see how much he would save if he
chose to be a Joker member. He can then uncheck (is this the right word?) it
again and see the non-Joker prices.
(Remember, I'm pretty new to MiniVend...)
So I made a checkbox:
<input type=checkbox name="joker" [checked joker on] value="on"
onClick="this.form.action='[process-target]';this.form.submit();">
[loc]I am a Joker member.[/loc]
This worked when you checked the checkbox, but after that the checkbox
remained checked all the time. Apparently, when you uncheck a checkbox, the
CGI value is just undefined and is not transmitted. A quick look into the
MiniVend session file showed me that "joker" was in fact still set to "on".
And "on" it would remain until the end of time...
A colleague gave me the idea to check the checkbox all the time and set it
to another value. Which is what I did with a bit of Javascript:
<input type=checkbox name="joker" [checked joker on] value="on"
onClick="checkJoker(this);this.form.action='[process-target]';this.form.subm
it();">
[loc]I am a Joker member.[/loc]
(This is in the <head>)
<script language="JavaScript" type="text/javascript">
<!--
function checkJoker(checkbox) {
if (checkbox.checked == true) {
checkbox.value = 'on';
} else {
checkbox.checked = true;
checkbox.value = 'off';
}
}
//-->
</script>
And it works! Perhaps there are simpler solutions to this problem and if so,
I'd like to hear about them! :-)
Best regards,
Eric
