html - Jquery select by class alternatives -

-

i have 2 html elements(span , input) represent same user property. in jquery script want select both elements. way found specify different ids , execute 2 queries 

$("#span\\.firstname") $("#input\\.firstname").

at moment looking solution. want use class attribute (specify class firstname on span , input , perform 

$(".firstname")

), css aren't ready , don't know classes required, can't use it. know, if exists other solution perform selection, class attribute.

<td>   <div>      <span id="span.firstname">${user.firstname}</span>      <span id="span.lastname">${user.lastname}</span>   </div>   <div>      <span>first name</span><input id="input.firstname" value="${user.firstname}"/>      <span>last name</span><input id="input.lastname" value="${user.lastname}"/>   </div> </td>

you can selector so: 

$("[id*='firstname']") // give both span , input of firstname etc

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...

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
