Check Item number and allowing for generating report.

Dear All,

I need javascript method for preventing from generating the report.

For example, Part-->Item number starts with D001-> right click select "Test Report" it should allow the user to generate the report.

Whereas the Part--->Itemnumber starts with T001--> right click select "Test Report" it should prompt message stating it is not applicable for this selected Item number.

I have designed the Report but i dont know to do validation in Javascript method and linked with the xslt report.

Can you anyone tried this before,then please guide me.

Thanks,

Tin.
