Javascript：更改'display'和'left'+切换类

Question

单击菜单按钮时，我想做两件事。首先，我希望条形变为十字形，已经使用x.classList.toggle("change");完成但不起作用的是#navi div应该向右滑动并显示。

以下是我尝试的内容:(不要介意#mainicons，#description等。

function sidebarFunction(x) {
    x.classList.toggle("change");
  ('#navi').style.left = "80px";
  ('#navi').style.display = "inline";
};

$(document).ready(function(){
  $("#navi").click(function(){
$("#navi .fa-chevron-down").toggleClass("rtoate180");
$("#navigation").slideToggle(500);
  });
});

  #more-bars{
    position:fixed;
    cursor: pointer;
    width:35px;
    height:25px;
    left: 18px;
    top: 20px;
  }

  .bar1,
  .bar2,
  .bar3 {
    position: relative;
    width: 35px;
    height: 5px;
    margin-top:6px;
    background-color: #843b62;
    transition: 0.4s;
    -webkit-transition: 0.4s;
    -o-transition: 0.4s;
    -moz-transition: 0.4s;
  }

  .change .bar1 {
    -webkit-transform: rotate(-45deg) translate(-9px, 6px);
    transform: rotate(-45deg) translate(-9px, 6px);
    -ms-transform: rotate(-45deg) translate(-9px, 6px);
  }

  .change .bar2 {
    opacity: 0;
  }

  .change .bar3 {
    -webkit-transform: rotate(45deg) translate(-8px, -8px);
    transform: rotate(45deg) translate(-8px, -8px);
    -ms-transform: rotate(45deg) translate(-8px, -8px);

Answer 1

要使用id选择元素，您必须像document.getElementById('navi')一样编写它 或者如果使用jquery使用$('#navi')。对于滑动工作使用不透明度而不是显示无。有关详细信息，您可以检查this answer

您可以切换课程并达到预期的效果，而不是改变风格

检查此样本

function sidebarFunction(x) {
    x.classList.toggle("change");
 
  document.getElementById('navi').classList.toggle('show')
  
 /* .opacity = "1";
  document.getElementById('navi').style.left = "80px";
