javascript - How to check whether the checkboxlist is checked atleast one in Struts2? -

-

i'm working in struts2 framework. have checkboxlist in code.

<div id="mycheckbox">     <td>       <s:checkboxlist theme="simple" name="claimlistview.claimstatus" list="#{'u':'unprocessed', 'p':'processed','r':'routed','s':'sent'}" id="claimstatus" required="true" value="defaultcolor"/>     </td> </div>

so want field required field. mean user should select @ least 1 check box. else error msg should throwed , prevent form submitted. how can achieve ?

i tried in jquery given below code.

var n = $("#mycheckbox input:checked").length; alert("the count : "+n); if (n>0) { return true; } else{ return false; }

i know i'm missing something. can me, i'm getting wrong ?

finally found out solution own question. below script working fine.

var n = $('input[name="claimlistview.claimstatus"]:checkbox:checked').length; if (n>0) { return true; } else{ return false; }

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...
