Hi Srinivas,

The following JavaScript code can be the following.

Var Cmsg;

if (HasValue(MY_FORM.P1.MydetailsSub.CoName)) // also you can check as if (FieldName.rawValue) != null


          CoName.rawValue = "";




          CoName.rawValue = "_CoName\u00a";

          Cmsg = CoName.rawValue;


All Unicode characters have an equivalent 6 character escape sequence consisting of \u followed by four hexadecimal digits. Within any literal string, it is possible to express any character, including control characters, using their equivalent Unicode escape sequence. For example:


"\u000d" (carriage return)

"\u000a" (newline character)

Thank you.

1) You said, this also can be achieved by checking !=null, fine,

if user enters a space/blank then, do i need   check like != " " (one space)....okay, if user enters multipe spaces? i do not want to consider the spaces would be some values!

how can i address this item?

thats why i want to go with HasValue

I guess, if user enters the spaces, then, HasValue become FALSE, am i correct?

2)Pls. let me know here in the below, Wht the developer is trying to do? (right now, our system is down, so, i can not test it)

      CoName.rawValue = "_CoName\u00a"; ===> how it looks to the end user, after executing this syntax/script? if developer/designer want to get it in a seperate new line, then, designer could use "\n" right?

CoName is text field in my_form.
