javascript - 带有单选按钮和 jQuery 的下拉菜单

问题描述

我编写了一个带有单选按钮的下拉菜单来更改我网站中的货币。我使用 jQuery 打开/关闭此下拉菜单，但货币更改不起作用。

该类expanded用于打开/关闭下拉菜单。

我认为错误来自这条线$('#' + $(e.target).attr('for')).prop('checked', true);，但我不知道如何修改它。我希望它检查正确的输入。

$('.maincar__currency').click(function(e) {
  e.preventDefault();
  e.stopPropagation();
  $(this).toggleClass('expanded');
  $('#' + $(e.target).attr('for')).prop('checked', true);
});

$(document).click(function() {
  $('.maincar__currency').removeClass('expanded');
});

.maincar__currency {
  display: flex;
  flex-direction: column;
  min-height: 32px;
  max-height: 32px;
  margin-left: auto;
  margin-bottom: 10px;
  overflow: hidden;
  border-radius: 6px;
  box-sizing: border-box;
  box-shadow: $shadowBox;
  font-size: 14px;
  font-weight: 500;
}

.maincar__currency label {
  display: flex;
  width: 80px;
  height: 32px;
  padding-top: 6px;
  padding-bottom: 6px;
  padding-left: 8px;
  margin-right: 0 auto;
  background-color: #fff;
  text-align: center;
  color: $mediumMainGrey;
  cursor: pointer;
  //box-sizing: border-box;
}

.maincar__currency label:hover {
  background-color: $extraLightGrey;
}

.currency {
  display: flex;
  width: 100%;
}

.currency input {
  display: none;
}

.currency img {
  //object-fit: contain;
  height: 20px;
  width: auto;
  margin-right: 6px;
}

.currency span {
  display: flex;
  //align-items: center;
  color: $mediumMainGrey;
  text-decoration: none;
}

.expanded {
  max-height: 128px;
}
