Function check

[stonner]

Hi,

the following code checks if the value of the field 'to' of a form is equal to 0049 and if yes it returns a message..

PHP Code:

      if (document.Formular.to.value == "0049") {
         alert('Wollen Sie die SMS ins Nirvana schicken?')
            document.Formular.to.focus();
         return false;
      } 


What would the code look like just to check if the value of that field starts with 0049?

Thank you!
