javascript - Differentiate between a dangerous redirect and an irrelevant ajax response -

-

on web page possible send ajax requests , jump page meaning ajax requests irrelevant , aborted browser. return 1 of these jquery ajax requests error handling might be:

readystate = 0 responsetext: "" status=0

but, note error handler may not invoked. depends when browser aborts request , when user selects go onto page. if invoked invoked above parameters.

here gets juicy. similar response happens when 302 redirect returned ajax request when location set domain. browser (both ie , ff) mangle 302 , invoke error handler same info:

readystate = 0 responsetext: "" status=0

i know 302 location set domain using fiddler. take fiddler away , see above.

i need able differentiate between

  • ajax requests aborted because user goes page
  • ajax requests aborted because redirects domain

but can't if exact same info both.

any tips? check window object or else in dom? note: can't predict when request return 302. can't see location header server side.

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
