Javascript : change 'display' and 'left' + toggle class

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，这已经通过 x.classList.toggle("change"); 完成，但不起作用的是 #navi 应该向右滑动并显示的 div。

这是我尝试过的:(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;

  .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);

Answer 1

要使用 id 选择元素，您必须像 document.getElementById('navi') 这样写 或者，如果使用 jquery，请使用 $('#navi') 。为了滑动正确工作，请使用不透明度而不是不显示。有关详细信息，您可以查看 this answer

无需更改样式，您可以切换类并获得所需的效果

检查这个样本

function sidebarFunction(x) {
    x.classList.toggle("change");
 
  document.getElementById('navi').classList.toggle('show')
  
 /* .opacity = "1";
  document.getElementById('navi').style.left = "80px";
   document.getElementById('navi').style.height = "30px";*/
 
};

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