[soma lingam]

In my jsp page i have a Textfield with a dropdown and two radio button
when i select one radio button the textfield value needs to be cleared and the cursor should point in the textfield it is working fine.

But when i click another radio button the textfield value should be cleared and dropdown selected value should be cleared and needs to be disabled and the cursor should point to the textfiled

What part are you having issues with? You can set the value of the select just as you can any other form element, and you can disable it via the disabled attribute.

I mean to say

when i click a radio button say "No" then page is refreshing but the cursor is not pointing to a particular textfield how i need to make sure that it should point the cursor in that field

Have you tried using the focus() method?

document.formName.elementName.focus();

I tried but the focus is not coming into the textfield because the values i am inserting into the textfield are coming through (Struts action class) so the page is refreshing i am explaining the scenario what i need like


In my jsp page i had One TextField (Say: Amount) and a drop down Box (Say: Currencies) and two radio buttons (Say 1. Negative 2. Positive)

STEP: 1

By default the "Amount Field is displayed by "0" and dropdown is selected to "currency name" and "Negative" radio button is selected.
(These are by defaultly mentioned in Struts action class).

I want to validate in such a way that
If i edit the "Amount textfield" with negative value (i.e., Ex: -273) and tabbing out it should not throw an error (Ex: "Invalid data")
because the "Negative" radio button is already clicked. ( see above mentioned STEP:1)

but when you click "Positive" radio button it should through error msg "Invalid data" and also the "Drop down" what is selected should be "disabled"
and the cursor should focus on the "AMount" textfield

If i enter "Positive value" in "AMount field" (Ex: 233) when "Positive radio button" is selected it should not through error message
if i select "Negative Radio button" then "Drop down" should be enabled and the cursor should point to the "Amount Field".

Note: the values should not be cleared in the "Amount textfield" in any of the scenarios
it should not take any invalid special characters say "@#$!*&^" etc.,

can any body suggest me to implement by giving example
