Hello,

My requirement is as below,

if ( my_text_field_1 == BLANK){ 

my_text_field_2.rawValue = "Blank"

}

if( my_text_field_1 = null){

my_text_field_3.rawValue = "NULL"

}

1) Pls. let me know How can do Java script

for this BLANK? is it a single space like " " (single space)...........if so, if user enters 2 spaces or 3 or 4 spaces, wht happens in that case? still my code works? or will it not work bcz we put only one space? 

2) Pls. consolidated the above JavaScript in a best practice way

Thank you
