Description
The Trim start command removes whitespace from the beginning of the aString parameter and returns a new string, without modifying the original one. Whitespace includes spaces, tabs, LF, CR, etc.
To return a new string with whitespace trimmed from both ends, use Trim. To return a new string with whitespace trimmed from the end of aString, use Trim end.
In the aString parameter, you can pass any text expression. It will be left untouched by the command.
The command returns the trimmed version of the aString string. If there is no whitespace at the beginning of aString, the returned string is identical as the one passed in parameter.
注
This command is based upon the trimStart Ecmascript specification.
Example
var $input; $output : Text
