Question

我尝试制作类似hamburger的内容，我想first click hamburger设置css（加号），但second click删除{{ 1}}，我在css中设置（减号）（想做切换器之类的东西）。我试图使用first click jquery-function，但是它不起作用，而是我的{{1消失了。如何在没有toogle并进行额外课程的情况下制作切换台？所有想做的都是改变.panel-title和toogleClass，如plus to minus minus to plus

时切换器

click

collapse panel

$(function() {

  $(".panel-title").click(function() {
    $('.panel-title button span:first-of-type').css({"top": "50%", "bottom": "50%"})
  });

});

不要使用javascript。只需将您的样式设置为添加到父级的collapsed类：

.panel-heading {
    cursor: pointer;
    transition: color .15s ease-in-out;
}

.panel-heading:hover {
    color: #5bb8e1;
}

.panel-heading h4 {
    font-weight: 400;
}

.panel-title {
    position: relative;
}

.panel-title button {
    background: transparent;
    width: 22px;
    height: 22px;
    border: 0;
    position: relative;
    float: right;
}


.panel-title button span {
    content: '';
    transition: .3s linear;
    position: absolute;
    background: #b9b9b9;
}

.panel-title button span:first-of-type {
    top: 25%;
    bottom: 25%;
    width: 5%;
    left: 48%;
}

.panel-title button span:last-of-type {
    left: 25%;
    right: 25%;
    height: 5%;
    top: 48%;
}

.panel-heading:not(.collapsed) .panel-title button span:first-of-type,
.panel-title button:hover span:first-of-type {
    top: 50%;
    bottom: 50%;
}
