Javascript problem - Jedi Name

miralize

Hi im making a Javascript page to churn out the last three letters of your first name


I have this so far

for ( i == document.jedin.firstn.value.length - 3 ; i == document.jedin.firstn.value.length ; i++)
{
  firstName = charAt[i];    
}

Where am I going wrong

I don't know anything about Javascript, so the statements looks a little bit confusing, but if the for loop works correctly firstName is being overwritten and so is only one character long!

Yup so use += instead of =

Yeah, also in the for statement (I don't know if it's the same for Javascript to be honest) you have ==, I think that should be = instead?

== to check if variables are equivalent
= to assign a variable/value to a variable.

You could try using the substr() function.

It might accept negative numbers like substr() does in perl and php.
