Regex expression validation is not working

[snow57]

Hi, 

The regex validation in the below code is not working. could someone please help me on this .

var nonPrint = "123Test*input";
gs.print('nonPrint1'+nonPrint);
var regex =/^[0-9][0-9]*$/;
var s = nonPrint.replace(regex, '_');
gs.print('nonPrint2' + s);

Appreciate for the leads.

Thanks

@snow57 Use Escape character (\) to match with a reserved letter of regex.

For example if you wish to match $ then it would be written as \$ if you wish to match / then it should be written as \/ if you wish to match \ then it should be written as // in the regular expression.

var nonPrint = "123Test*input";
gs.print('nonPrint1 '+nonPrint);
var regex =/^[0-9][0-9]*\$/;
var s = nonPrint.replace(regex, '_');
gs.print('nonPrint2 ' + s);

Hope this helps.
