Hi   I have a text_field as <%= text_field :sd_resol, "hours", "size" => 2, "value" => '00' %> And on submit_to_remote :condition I am calling a script to check whether hour contains only numeric data..How can I do it..I tried like

if(!isNumeric($F('sd_resol_hours') ))

   But is not working..How can I do this?Please help

condition needs to be a fragment of javascript which evaluates to true (or anything javascript will consider to be true) when the request should be made, ie :condition => "isNumeric($F('sd_resol_hours'))" assuming you have a function called isNumeric that returns the appropriate value

"it's not working" is the single most unhelpful thing you can say when asking a question. Say what happens, what you expected to happen etc...

O sorry I thought isNumeric is a function by javascript..So things not that much easy with javascript..I thought in the rails way that it will do some check using regex /(^\d+$)|(^\d+\.\d+$)/ ..So could you please tell me how can I do this?

Are you trying to see if it's an IP address?

\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\. Should suffice.

Hi     I could solve it like   var anum=/(^\d+$)|(^\d+\.\d+$)/   hour=anum.test($F('sd_resol_hours'))   minute=anum.test($F('sd_resol_minutes')) if (ho==false || min == false)    code here

      Thanks for all the reply Sijo
