Scripting: TrimString

TrimString

Introduced

v5.0

Description

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.

Scripting Syntax

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

Return Value

String

Parameters

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

Examples

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, "");
}
