New to JavaScript

Hi.

I am new to JavaScript and to this forum.

I hope somebody can help me with this Script:

I have a page with a form validator. It works fine. However, I have 2 forms on this page and want to use the validation script for either form 1 or form 2. The fields on the form have different names.

Here is the script ::


<SCRIPT LANGUAGE="JavaScript">
<!-- Begin

function validate() {

var theMessage = "Please complete the following: \n-----------------------------------\n";
var noErrors = theMessage


// make sure field is not blank
if (document.form1.First_Name.value=="") {
theMessage = theMessage + "\n --> Your First Name";
}

// If no errors, submit the form
if (theMessage == noErrors) {
return true;

} else {

// If errors were found, show alert message
alert(theMessage);
return false;
}
}
// End -->
</script>


Question::
In my form 2 I have a field called "Friends_First_Name". What do i have to do that the script works either on form 1 or form 2?

Any help would be great.

Regards
Syd

Establish which forms 'submit' button caused the routine to be called and use if...else statements. E.g., below:

Code: Select all

if (form1){
   if (document.form1.First_Name.value=="") {
   theMessage = theMessage + "\n --> Your First Name";
   }
}
else {
   if (document.form2.Friends_First_Name.value=="") {
   theMessage = theMessage + "\n --> Your First Name";
   }
}

I'll let you have a think aboout how you determine which form's submit button called the function.

Many thanks Geoff.

I'll try that and came back later.

Thanks again, I have solved the problem:

Each form is using the same validation function; I gave the 2 functions different names so each for accesses the appropriate one!
