if statment within an if statment...nesting if statements 1

[meriwether]

is is possible to nest if statments? it seems somewhat logical, but i cannot get this to work properly.

here's a snippit of the code:

// Phone Number Validation

if(phone != "Phone Number&quot { // phone # is optional
if(!validatePhone(phone)) {
window.document.formname.phone.focus();
alert('Please enter a valid Phone Number');
return false;
}
} // phone # is optional

else {

// Email Address Validation

if(emailaddress != "Email Address&quot { // email address is optional
if(!validateEmail(emailaddress)) {
window.document.formname.emailaddress.focus();
alert('Please enter a valid Email Address');
return false;
}
} // email address is optional

else {

// Passed Validation

return true; // form validation passed

}
}

any pointers on nesting if statements would be greatly appreciated. need more info, i'll post all the code i suppose. thx.

your syntax is legal, but here's your current logic:

if(phone != "Phone Number&quot {
// validate the phone number
}
else {
if(emailaddress != "Email Address&quot {
// if no phone number but yes email, validate the email address
}
else {
// if no email or phone, return true
}
}


what you're looking for is probably something like so, and does not require nesting:

if(phone != "Phone Number&quot {
// validate the phone number
if (invalid phone) return false;
}

if(emailaddress != "Email Address&quot {
// validate the email address
if (invalid email) return false;
}
// did not fail above, so data ok
return true;
