The function I want to complete is to replace the carriage return linefeed (\ r \ n) in the multi-line text box with a comma (,).
UseVaRS=Document. All ('Textboxdata'). Value to obtain its value,ProgramWork properly, but use$ ("# Textboxdata"). Val ()The program does not work properly when obtaining the value.
Puzzling, depressing...

$ ( " # Btnok " ). Click ( Function ()
{
VaR Values = $. Trim ($ ( " # Textboxdata " ). Val ());
If (Values. Length = 0 )
{
Window. Alert ( " Note: You have not entered any items. If you discard the input, click "cancel ". " );
Return False ;
}
Else
{
VaR S = Document. All ( ' Textboxdata ' ). Value; // If var S = values is used, \ r \ n --> "," cannot be replaced! $ ("# Textboxdata"). Val () is how to obtain the value in textarea?
S = S. Replace ( / \ R \ n / G, " , " );
Window. returnvalue = S;
Window. Close ();
}
Return False ;
});
