Use indexOf to check field for certain characters.

[arobertson]

Hi All,

I have the following onSubmit() script that checks to see if a field contains :// and if so, stops the form from being saved and displays a pop-up.

function onSubmit() {

   var name = g_form.getValue('name');
   var altname = g_form.getValue('u_alternative_name');

   if (name.indexOf('://') > -1 || altname.indexOf('://') > -1) {
   alert('Please enter only the domain without any prefix');
   g_form.submitted = false;
   return false;
   }
}

I have now been asked to amend the script to check if a , (comma) has been entered?

Any ideas on how to do this? Should i create an array of the letters, symbols that i want to search for?

Hi Alex, since you're only checking for only two type of characters, I will perhaps keep it simple. If it grows above 4 type of characters, then you probably want to think in a different approach.

  if (name.indexOf('://') > -1 || altname.indexOf('://') > -1 || name.indexOf(',') > -1 || altname.indexOf(',') > -1) {  

            alert('Please enter only the domain without any prefix');  

            g_form.submitted = false;  

            return false;  

  }

Thanks,

Berny

Works perfectly.
