on click help...

[thompom]

Hi,

On a form my validation is done through the onclick event of a button

onclick="this.form.a.value='A';return EW_checkMyForm(this.form);"

function EW_checkMyForm

function EW_checkMyForm(EW_this) {
if (EW_this.x_stockreg && !EW_hasValue(EW_this.x_stockreg, "TEXT" )) {
            if (!EW_onError(EW_this, EW_this.x_stockreg, "TEXT", ">Please Enter Car Reg..."))
                return false; 
        }

return true;
}

this works fine - but i have an issue of impatient clickers so, to keep it simple i want an alert to popup
and say 'click once' - this would give the page time to submit [may be annoying for user - but stops the record being written twice!]

the process of events would then be

1) Button clicked
2) function EW_checkMyForm run to make sure x_stockreg field filled - if not return false
3) if x_stockreg filled then submit form with a value for A
4) alert saying click once

i dont think i can do all this without writing a new function but have limited experience and would really appreciate your help.

if i am not making sense please let me know.

thanks MG

Right before "return true;", add the alert:

...

alert('Your message here');
return true;

of course, you should not rely on client-side JavaScript for validation or dup-checking. For example, what if the user has JS disabled? They could submit as many times as they liked.

This sort of thing should always be done server-side, with client-side as a fall-back.

Hope this helps,
Dan

Please consider what he mentions carefully. There are many ways to prevent dupes (for instance).

Make sure your web page and css validates properly against the doctype you have chosen - before you attempt to debug a problem!
