space bar validation in flash

Question

Hi I got a form for the first name and last name in my flash website For the two fields I defined them as not null but when you just click the spacebar and click on submit its taking it Can some one please help me how do I write the validation for not taking space bar as an Input and and the field should not be empty (Note: I am using actionscript 2.0)

_validateParams[pCnt++] = { type: "notNull",  input: win.firstNameInput , isSendData:true, dataName:"firstName"};
  _validateParams[pCnt++] = { type: "notNull",  input: win.lastNameInput, isSendData:true, dataName:"lastName"};

Answer 1

I am unsure how to write it in ActionScript, but what you can do is, you could write a trim() routine(or use one that is available) which would remove leading and trailing whitespace, and then check if the resulting string length is 0. This would also remove only spaces if that is the only input that the user had typed.
