javascript - How to disable all links inside a nested ul, except for the ones at the lowest level? -

-

let's have list, this:

<ul> <li><a href="sitepages/introduction.aspx">introduction</a>     <ul>         <li><a href="sitepages/aboutme.aspx">about me</a></li>         <li><a href="sitepages/aboutthecompany.aspx">about company</a>             <ul>                 <li><a href="sitepages/history.aspx">history</a></li>                 <li><a href="sitepages/locations.aspx">locations</a>                     <ul>                         <li><a href="sitepages/belgium.aspx">belgium</a></li>                         <li><a href="sitepages/france.aspx">france</a></li>                         <li><a href="sitepages/germany.aspx">germany</a></li>                         <li><a href="sitepages/norway.aspx">norway</a></li>                     </ul>                 </li>             </ul>         </li>     </ul> </li> </ul>

i have script turns nested ul accordion top levels shown @ first. clicks on link inside li containing ul, expands ul , on.

the thing is, while works fine when no links provided, want disable default behavior of every "a" tag, except ones @ lowest level. li tags @ lowest level, link inside them, should still active links.

here's javascript code disables default behavior of top level links:

    $this.find("li").each(function(){     if ($(this).find("ul").size() != 0) {         if ($(this).find("a:first")) {             $(this).find("a:first").click(function(){ return false; });              } });

while top level link (introduction) ignore default behavior (redirecting) upon clicking, expand , show "about me" , "about company" options. when click on "about company", still redirects.

what should edit in code set default behavior of every "a" tag false, except last ones (in example: country names)?

thanks help!

you can setup 2 handlers. 1 disable links within unordered list , handle clicks on last unordered list:

// disable links within ul $('ul').on("click", "a", function(e){     e.preventdefault(); });  // second handler bind last ul $('ul:last').on("click", "a", function(e){     window.location.href = $(e.target).attr('href'); });

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...
