surname = surname.replace(/^\s+/, ����).replace(/\s+$/, ����);�m= surname.replace �] / ^ \ s + / �� �A �� �^ �C��N�] / \ s +��/ �A �� �� �^ ;

To answer this..�n�^���o��.. Javascript and Jscript are the same meaning with the different versioning. JavaScript�MJScript���O�ۦP���N�q�P���P�������C Jscript is the version of Microsoft javascript. JScript���O������Microsoft��JavaScript �C Some time the Document Object Model might differ from the Javascript.�@�q�ɶ����ɹ�H�ҫ��i��|���Ҥ��P��JavaScript �C And Jscript works only on IE browser.�MJScript�u��IE�s��C
This might answer your question.�o�i��|�^���A�����D�C
