javascript - BlockUI scrolls to top -

-

i using jquery blockui plugin:

function block(msg) {     $.blockui({         message: msg,         css: {             border: 'none',             padding: '15px',             backgroundcolor: '#000',             '-webkit-border-radius': '10px',             '-moz-border-radius': '10px',             opacity: .8,             color: '#fff'         }     }); }  function unblock() {     $.unblockui(); }

the problem facing is, call it, scrolls page top. not good.

here generated html:

enter image description here

is there modify not touch pageoffset / scrolling? there preserve or anything?

thanks

called here:

function callbump(realid) {      block('bumping...');      $.ajax({         type: "post",         url: "calendarservices.aspx/bump",         data: 'id=' + realid,         success: function (data) {             $('#calendar').fullcalendar('refetchevents');             unblock();         } ,         error: function () {             unblock();         }     }); }

i'm guessing jump top caused having this:

<a href="#" id="do_bump">bump!</a>

whatever click event have bound link executing continues attempt navigate "#" causing jump.

it can fixed capturing event parameter (add e click event handler) , calling preventdefault() on it. prevents default link click behavior occurring, navigate href attribute value.

given comments, have this:

$(btnbump).off('click');  $(btnbump).on('click', function () {      callbump(event.realid);  });

where event coming from? window.event? assuming jquery might mangle event, try (you have add event parameter e):

$(btnbump).on('click', function(e) {     callbump(event.realid);     e.preventdefault(); });

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
