Hi,
I am trying to implement wizard for my application. I am doing it with
hidden divs.
For navigation purposes: I am using hidden input fields such as:
<input id="wizard_current_state" name="state"
type="hidden" value = 1 />
<input id="wizard_previous_state" name="state"
type="hidden" value = 1
/>
So that when someone presses next, i can increment the current_state to
2 in JavaScript Function that i have written.
$(''wizard_previous_state'').value = previous
$(''wizard_current_state'').value
current = $(''wizard_current_state'').value = previous + 1
But "previous + 1 " is evaluated as 1 + 1 = 11 (string concat).
How do i say that i want hidden value to be integer?
Any suggestions?
Regards,
Sandeep G

But you should be able to do what you want with something like current = $(wizard_current_state).value = +previous + 1 In Javascript, using a unary + operator on a string containing a number will produce the number. -- Rick DeNatale My blog on Ruby http://talklikeaduck.denhaven2.com/ --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Re: hidden inputs fields are always strings(chars)?
