how to display value in textbox

tllcll · 10-21-2005, 07:12 AM

I have a form, 1st page called first.jsp. in this form I have multiple fields. once user enters the first field, I call to the second.jsp to process by using 'onchange="location.href='second.jsp?first_field='+this.value"'

in second.jsp, it will get the value for 2nd field and return to first.jsp. I manage to get the value returned to first.jsp but not able to display in the second field textbox.

how do I do it

Please show us your code, otherwise is is pretty well impossible to respond sensibly.
