javascript - jQuery get the total position from an id -

-

i want set focus position on variable #id after ajax reloads content within container. container has overflow:auto; in see scrollbar if content large. after inserting new content, can't focus set on #id i'm giving set on.

i first tried set focus on id:

<script type="text/javascript"> function setfocus(ulid) {   var heightul = $("#"+ulid).offset();   $("#"+ulid).focus(); } </script>

later tried total height of id, put offset() on it, $("#"+ulid).offset().top; or $("#"+ulid).position().top;.

function setfocus(ulid) {   var heightul = $("#"+ulid).offset().top;   $("#"+ulid).stop().animate({ scrolltop: heightul }, 'fast'); }

but isn't working either. position() 0 in return , offset() returns object's height relative parent. , not total height object positioned within container.

the html:

<div class="info-container edit" id="info-container-edit">   <span class="cat">info 1</span>   <ul id="info1" class="cat-list music">     <li>...</li>     <li>...</li>     <li>...</li>     <li>...</li>   </ul>   <span class="cat cat">info 2</span>   <ul id="info2" class="cat-list music">     <li>...</li>     <li>...</li>     <li>...</li>     <li>...</li>   </ul>   <span class="cat cat">info 3</span>   <ul id="info3" class="cat-list music">     <li>...</li>     <li>...</li>     <li>...</li>     <li>...</li>   </ul>   <span class="cat cat">info 4</span>   <ul id="info4" class="cat-list music">     <li>...</li>     <li>...</li>     <li>...</li>     <li>...</li>   </ul> </div>

the ajax code refreshes container #info-container-edit. problem example want focus on #info3 setfocus('info3');. seems returns height of #info2 , not total height container #info-container-edit till #info3.

can point out how fix problem? if can position height of #id within container, should problem fixed. or how set display focus on #id?

you use .scrollintoview():

document.getelementbyid(ulid).scrollintoview(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
