javascript - Replicating jQuery slideToggle without jQuery -


since anki doesn't support jquery, how go converting jquery on particular document same effects produced in vanilla js, or purely in css3 (specifically of + button, , when clicking on list items)?

$(document).ready(function () {      $("#show-pronunciation").on("click", function () {          $(".pronunciation").slidetoggle();      });      $("li").on("click", function () {          $(this).find("dl").slidetoggle();      });  });
body {      font-family: avenir, futura, sans-serif;      background-color: #f7f7f7;  }    .definitions dl {      border-left: 2px solid #ff1919;      padding-left: 5px;      }    dt {      font-weight: bold;  }    dd {      margin-left: 1em;  }    .main {      margin: 20px 20px 0 20px;      border: transparent;      border-radius: 5px;      /*padding: 15px 10px 5px 10px;*/      border-collapse: collapse;      background-color: #ff4c4c;      padding-bottom: 5px;  }    .header {      border-radius: 5px;      padding: 5px;      background-color: white;  }    .content {      margin: 5px 5px 0px 5px;      border: transparent;      border-top: none;      border-radius: 5px;      padding: 5px;      background-color: #fce8e8;  }    .info {      clear: both;      padding: 5px;      display: block;  }    .grammatical-info {      display: inline-block;      border: transparent;      border-radius: 5px;      float: left;      padding: 3px;      background: deepskyblue;      color: white;  }    .level {      display: inline-block;      border: transparent;      border-radius: 5px;      float: right;      padding: 3px;      background: crimson;      color: white;  }    .foreign-word {      display: inline-block;      border: transparent;      position: relative;      font-size: 20pt;  }    .pronunciation {      display: none;      overflow: auto;      border: transparent;      border-radius: 10px;      background-color: white;      font-size: 8pt;      position: absolute;      left: -2px;      bottom: 40px;      width: 100%;      text-align: center;  }    .btn {      font-size: 20pt;      background-color: transparent;      border: none;      border-radius: 28px;      cursor: pointer;      text-decoration: none;      text-shadow: none;      display: inline-block;      color: #999;  }    .btn:hover {      color: #aaa;  }    .btn:active {      color: #ccc;  }    #play-sound {      float: right;  }

you can use css transitions that. e.g:

.pronunciation, li dl {   overflow: hidden;   transition: height .3s linear; } .hidden {   height: 0!important; }

take @ code below (same logic yours, converted vanilla javascript , css3):

document.addeventlistener('domcontentloaded', function() {    var show = document.getelementbyid('show-pronunciation');    var pron = document.queryselector('.pronunciation');        pron.style.height = pron.clientheight + 'px';    pron.classlist.add('hidden');      show.addeventlistener('click', function(e) {      pron.classlist.toggle('hidden');    });        [].foreach.call(document.queryselectorall('li'), function(el, i) {      var dl = el.queryselector('dl');      dl.style.height = dl.clientheight + 'px';            el.addeventlistener('click', function() {        dl.classlist.toggle('hidden');      });    });    });
body {    font-family: avenir, futura, sans-serif;    background-color: #f7f7f7;  }  .definitions dl {    border-left: 2px solid #ff1919;    padding-left: 5px;  }  dt {    font-weight: bold;  }  dd {    margin-left: 1em;  }  .main {    margin: 20px 20px 0 20px;    border: transparent;    border-radius: 5px;    /*padding: 15px 10px 5px 10px;*/    border-collapse: collapse;    background-color: #ff4c4c;    padding-bottom: 5px;  }  .header {    border-radius: 5px;    padding: 5px;    background-color: white;  }  .content {    margin: 5px 5px 0px 5px;    border: transparent;    border-top: none;    border-radius: 5px;    padding: 5px;    background-color: #fce8e8;  }  .info {    clear: both;    padding: 5px;    display: block;  }  .grammatical-info {    display: inline-block;    border: transparent;    border-radius: 5px;    float: left;    padding: 3px;    background: deepskyblue;    color: white;  }  .level {    display: inline-block;    border: transparent;    border-radius: 5px;    float: right;    padding: 3px;    background: crimson;    color: white;  }  .foreign-word {    display: inline-block;    border: transparent;    position: relative;    font-size: 20pt;  }  .pronunciation {    overflow: auto;    border: transparent;    border-radius: 10px;    background-color: white;    font-size: 8pt;    position: absolute;    left: -2px;    bottom: 40px;    width: 100%;    text-align: center;  }  .btn {    font-size: 20pt;    background-color: transparent;    border: none;    border-radius: 28px;    cursor: pointer;    text-decoration: none;    text-shadow: none;    display: inline-block;    color: #999;  }  .btn:hover {    color: #aaa;  }  .btn:active {    color: #ccc;  }  #play-sound {    float: right;  }    .pronunciation, li dl {    overflow: hidden;    transition: height .3s linear;  }  .hidden {    height: 0!important;  }

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
