Hi everyone,

With no value in fields, after users click on search. All the data are been display.

Therefore, I want to make some fields be require before users perform a search.

I know Javascript is able to do this. I'm wondering if there's anything in xslt or xml that check fields as well.

Thanks

XSLT is output oriented, not input oriented.

However, you can store the input in a intermediate table, read out the table again and then check the field values and do the appropriate action. This is a two-step process.

For an example, look at thread http://www.fmforums.com/forum/showtopic.php?tid/162705/
