Using left() in a function

Run Example


public string function capitalize( required string text ) {
	return uCase( left( arguments.TEXT, 1 ) ) & right( arguments.TEXT, len( arguments.TEXT ) - 1 );
}

Using left() to test values

In this example we'll use left() to test the first five characters of a request context variable.

if( listFindNoCase( "super,great,coder,rulez", left( rc.ANSWER, 5 ) ) ) {
	writeOutput( "You are an awesome developer!" );
}

Using left() as a member function

In this example we'll use left() as a member function inside a function to help us to capitalize the first letter in a string.

Run Example


public string function capitalize( required string text ) {
	return arguments.TEXT.left( 1 ).ucase() & arguments.TEXT.right( arguments.TEXT.len() - 1 );
}
