javascript - 添加和删​​除多个元素的类(JQuery 和 JavaScript)

Question

我能够得到一个合适的答案来编辑上一个问题中的代码。

上一个问题的链接: Add and remove classes for multiple elements

现在我已经开发了之前的代码，并添加了内容，当点击图标时，其内容将被显示或隐藏。

此代码的问题在于，通过单击任何可用图标，所有图标的内容都会显示或隐藏。

但这不是我想要的。我想通过点击每个图标来显示相应的内容，而点击另一个图标时，所有内容都会被隐藏，只显示与被点击的图标相关的内容。

$('body').on('click', '.icon_product', function() {
    $(this).toggleClass("change_icon-product");
    $(this).parent().siblings().find('.icon_product').removeClass("change_icon-product");

    $(this).find(".txt-content").toggleClass("Toggle_txt-content");
 });

.icon_product {
    display: inline-block;
    cursor: pointer;
    position: relative;
    padding: 15px;
    margin-top: 0px;
}

.icon-line1_product,
.icon-line2_product {
    width: 35px;
    height: 5px;
    background-color: #f00;
    margin: 6px 0;
    border-radius: 10px;
    transition: all 0.6s ease-in-out;
    -webkit-transition: all 0.6s ease-in-out;
    -moz-transition: all 0.6s ease-in-out;
    -o-transition: all 0.6s ease-in-out;
    -ms-transition: all 0.6s ease-in-out;
}

.icon-line2_product {
    transform: rotate(90deg) translate(-11px, 0px);
    -webkit-transform: rotate(90deg) translate(-11px, 0px);
    -moz-transform: rotate(90deg) translate(-11px, 0px);
    -o-transform: rotate(90deg) translate(-11px, 0px);
    -ms-transform: rotate(90deg) translate(-11px, 0px);
}

.change_icon-product .icon-line1_product {
    transform: rotate(45deg) translate(8px, 0px);
    -webkit-transform: rotate(45deg) translate(8px, 0px);
    -moz-transform: rotate(45deg) translate(8px, 0px);
    -o-transform: rotate(45deg) translate(8px, 0px);
    -ms-transform: rotate(45deg) translate(8px, 0px);
}

.change_icon-product .icon-line2_product {
    transform: rotate(-45deg) translate(8px, 0px);
    -webkit-transform: rotate(-45deg) translate(8px, 0px);
    -moz-transform: rotate(-45deg) translate(8px, 0px);
    -o-transform: rotate(-45deg) translate(8px, 0px);
    -ms-transform: rotate(-45deg) translate(8px, 0px);
}

Answer 1

因此，您也想删除其他内容，如果打开了另一个内容，您只需添加一行代码:

$(this).parent().siblings().find('.txt-content').removeClass("Toggle_txt-content");

一旦另一行打开，上面的行就会删除或隐藏其他内容。

这是演示:

$('body').on('click', '.icon_product', function() {
    $(this).toggleClass("change_icon-product");
    $(this).parent().siblings().find('.icon_product').removeClass("change_icon-product");
    $(this).find(".txt-content").toggleClass("Toggle_txt-content");
    $(this).parent().siblings().find('.txt-content').removeClass("Toggle_txt-content");
 });

body {
  background: transparent; /* Make it white if you need */
  color: #fcbe24;
  padding: 0 24px;
  margin: 0;
  height: 100vh;
  display: flex;
  justify-content: center;
  align-items: center;
  font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;
}

.icon_product {
    display: inline-block;
    cursor: pointer;
    position: relative;
    padding: 15px;
    margin-top: 0px;
}

.icon-line1_product,
.icon-line2_product {
    width: 35px;
    height: 5px;
    background-color: #f00;
    margin: 6px 0;
    border-radius: 10px;
    transition: all 0.6s ease-in-out;
    -webkit-transition: all 0.6s ease-in-out;
    -moz-transition: all 0.6s ease-in-out;
    -o-transition: all 0.6s ease-in-out;
    -ms-transition: all 0.6s ease-in-out;
}

.icon-line2_product {
    transform: rotate(90deg) translate(-11px, 0px);
    -webkit-transform: rotate(90deg) translate(-11px, 0px);
    -moz-transform: rotate(90deg) translate(-11px, 0px);
    -o-transform: rotate(90deg) translate(-11px, 0px);
    -ms-transform: rotate(90deg) translate(-11px, 0px);
}

.change_icon-product .icon-line1_product {
    transform: rotate(45deg) translate(8px, 0px);
    -webkit-transform: rotate(45deg) translate(8px, 0px);
    -moz-transform: rotate(45deg) translate(8px, 0px);
    -o-transform: rotate(45deg) translate(8px, 0px);
    -ms-transform: rotate(45deg) translate(8px, 0px);
}

.change_icon-product .icon-line2_product {
    transform: rotate(-45deg) translate(8px, 0px);
    -webkit-transform: rotate(-45deg) translate(8px, 0px);
    -moz-transform: rotate(-45deg) translate(8px, 0px);
    -o-transform: rotate(-45deg) translate(8px, 0px);
    -ms-transform: rotate(-45deg) translate(8px, 0px);
}
