javascript - Hiding an unordered list when it has no elements -


i have problem seems @ first total no-brainer , easy task.

i have javascript plugin on page generates table of contents list sidebar of wordpress pages. purpose hide text widget element of #toc when list within has no elements. i'm trying solve using jquery no luck.

the html:

<div class="textwidget">    <div id="toc">      <ul></ul>    </div>  </div>

the javascript:

jquery(document).ready(function ($) {      if (!$('#toc').children('ul').has('li')) {         $('#toc').parent().hide();     }  });

my script should hide specific #toc's parent, because has no child <li> elements, doesn't. instead, when remove ! if sentence, script hides list, if had in it. hides lists have elements in them. totally missing here?

simply use this:

$(document).ready(function () {     if ($('#toc ul li').length < 1) {         $('#toc').parent().hide();     } });

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
