    how to get value without submitting a page

    Hi,

    I have a form that has many fields (textbox/listbox). when user enter/change a value in the first textbox, I need to pass this value to the database to check whether it exist and get the other values to be displayed to other fields in that form (i cannot get the javascript value to be pass to jsp without reload/refresh/submit. But, I need to get the user entered value, so I thought of hidden popup, iframe, etc but not sure how I could apply and which best suit this case). If I submit the page then I can easily get the value thru 'request.getParameter("fieldname") but cannot use this because I cannot submit the page.

    Pls help and possible provide me with the sample coding

    Thanks again

    You could use a popup or an iframe, or you could use AJAX.

    Inside the iframe put a page that contains a form with the elements you need.

    I suggest you give the iframe very small dimensions and absolutely position it off the left side of the viewport to hide it.
