Question

I’m trying to do something that should be very basic in SalseForce. I just need a button to run a small piece of javascript. It’s throwing the following error at the moment “Invalid assignment left hand side error”. Any help would be greatly appreciated.

if (  {!Contact.MailingPostalCode} =  'SC') {window.open('http://www.google.com','mywindow'); }

if (  {!Contact.MailingPostalCode}  =  'FL')  {window.open('http://www.yahoo.com','mywindow');  
}

Thanks

Answer 1

Your = needs to be ==. You are assigning and what you want to do is compare.

EDIT: Also, your ‘not’, !, may need to be on the outside. I’m not familiar with the SalesForce side.

EDIT 2: Try it this way:

if ({!Contact.MailingPostalCode} == 'SC') {
    window.open('http://www.google.com','mywindow');
}
if ({!Contact.MailingPostalCode} == 'FL') {
    window.open('http://www.yahoo.com','mywindow');
}

TESTING:

if ({!Contact.MailingPostalCode} == 'SC') {
    window.open('http://www.google.com','mywindow');
}
else if ({!Contact.MailingPostalCode} == 'FL') {
    window.open('http://www.yahoo.com','mywindow');
}
else {
    alert({!Contact.MailingPostalCode});
}

EDIT 3:
For completeness, @Zach Colon’s code is:

if ('{!Contact.MailingState}' == 'SC') {
    window.open('http://www.google.com','mywindow');
}
if ('{!Contact.MailingState}' == 'FL') {
    window.open('http://www.yahoo.com','mywindow');
}
