JScript and other languages offer sophisticated string manipulation functions via regular expressions. However regular expressions can be a little daunting to learn. This command provides a simple solution for the common task of triming extra space characters from from the front or end of a string. To write a truly user-friend interface it is prudent to always clean input strings in this fashion.

Note: This function does not remove any tab characters (\t) or linefeeds (\n) from the string.

oString = TrimString( StringToTrim, [TrimLeft], [TrimRight] );

String

Parameter	Type	Description
StringToTrim	String	Input that might contain extra white space characters
TrimLeft	Boolean	whether to remove all leading white space Default Value: true
TrimRight	Boolean	whether to remove all trailing white space Default Value: true

1. JScript Example

cleanedString = TrimString( "   myname   " ) ;

// cleanedString will contain "myname"

Application.LogMessage(cleanedString);

2. JScript Example

/*

	Demonstration of how JScript's regular expression functionality can be used instead 

	of the TrimString command

*/

Application.LogMessage( TrimSpaces( "     myname "   ) ) ;

function TrimSpaces( in_str )

{

	// Strip front and back spaces

	// (also cleans out \t and \n characters)

	return in_str.replace(/(^\s*)|(\s*$)/g, "");

}
