javascript - 向表单添加多个切换器

Question

我想在切换打开时将#bounds 的边框颜色更改为绿色，但现在当有多个切换切换时，它会在点击其他切换时更改第一个切换颜色。

我只是希望能够进行多次切换并维护绿色 = 打开和灰色 = 关闭的第一个切换行为。

$("input:radio").click(function(ev) {
  if (ev.currentTarget.value == "1") {
    $('#switchtoggle').removeClass('gray');
    $('#switchtoggle').addClass('green');

  } else if (ev.currentTarget.value == "0") {
    $('#switchtoggle').addClass('gray');
    $('#switchtoggle').removeClass('green');

  }
});

#switchtoggle {
  padding: 2px;
  transition: all .2s ease;
  border-radius: 2em;
  overflow: auto;
  float: left;
  color: transparent;
  border: 3px solid #e8e8e8;
}

#switchtoggle.active {
  border-color: #7FC6A6;
  transition: all 1s ease-in-out;
}

#switchtoggle label {
  float: left;
  width: 3.5em;
  height: 1.5em;
  margin: 0;
}

#switchtoggle label span {
  text-align: center;
  display: block;
  background: #7FC6A6;
  width: 1.75em;
  height: 1.5em;
  border-radius: 20px;
  transition: 350ms all;
  float: left;
}

#switchtoggle label input {
  position: absolute;
  width: 2.0em;
  height: 1.25em;
  opacity: 0;
}

#switchtoggle label input.off:checked+span {
  background-color: #e8e8e8;
  color: transparent;
  margin-left: 1.75em;
}

#switchtoggle label input.off:checked {
  display: none;
}

#switchtoggle label input.on:checked+span {
  background: #7FC6A6;
  color: transparent;
  border-radius: 1em;
  float: left;
  margin-left: 0;
}

#switchtoggle label input.on:checked {
  display: none;
}

.switchtoggle.gray {
  border: 3px solid #e8e8e8 !important;
}

.switchtoggle.green {
  border: 3px solid #7FC6A6 !important;
}

#switchtoggle label input.off:checked+#switchtoggle {
  border: 3px solid #e8e8e8 !important;
}

您的 JavaScript 当前尝试在 ID 为 switchtoggle 的元素中添加和删除绿色/灰色类。由于第一次出现是第一个切换元素，因此它切换了它。

要切换单击的单选输入的 .switchtoggle 元素，搜索具有类 .switchtoggle 的已单击复选框的下一个父级(使用 jQuery 函数 parents())并在那里删除/添加类:

$("input:radio").click(function(ev) {
  var label = $(ev.target).parents('.switchtoggle');
  if (ev.currentTarget.value == "1") {
    label.removeClass('gray');
    label.addClass('green');

  } else if (ev.currentTarget.value == "0") {
    label.addClass('gray');
    label.removeClass('green');

  }
});

#switchtoggle {
  padding: 2px;
  transition: all .2s ease;
  border-radius: 2em;
  overflow: auto;
  float: left;
  color: transparent;
  border: 3px solid #e8e8e8;
}

#switchtoggle.active {
  border-color: #7FC6A6;
  transition: all 1s ease-in-out;
}

#switchtoggle label {
  float: left;
  width: 3.5em;
  height: 1.5em;
  margin: 0;
}

#switchtoggle label span {
  text-align: center;
  display: block;
  background: #7FC6A6;
  width: 1.75em;
  height: 1.5em;
  border-radius: 20px;
  transition: 350ms all;
  float: left;
}

#switchtoggle label input {
  position: absolute;
  width: 2.0em;
  height: 1.25em;
  opacity: 0;
}

#switchtoggle label input.off:checked+span {
  background-color: #e8e8e8;
  color: transparent;
  margin-left: 1.75em;
}

#switchtoggle label input.off:checked {
  display: none;
}

#switchtoggle label input.on:checked+span {
  background: #7FC6A6;
  color: transparent;
  border-radius: 1em;
  float: left;
  margin-left: 0;
}

#switchtoggle label input.on:checked {
  display: none;
}

.switchtoggle.gray {
  border: 3px solid #e8e8e8 !important;
}

.switchtoggle.green {
  border: 3px solid #7FC6A6 !important;
}

#switchtoggle label input.off:checked+#switchtoggle {
  border: 3px solid #e8e8e8 !important;
}
