hi,I have a form where i have 2 textboxes,1 dropdown and a submit button. when i select an option from the dropdown, values for the other fields are fetched from DB and displayed in the form. i am doing this through javascript by submitting the form once the option from dropdown is selected. the user can change the values that are fetched from the DB and submit again using submit button. however by clicking the browsers bcak button user should not submit the form using submit button. ie user should not resubmit(by clicking on the submit button provided) the form by coming thrpugh the browsers back button. how to handle this.
