javascript - 一个输入的多个标签上的复选框动画

Question

.select-label 的 label 在 .pick- select 被选中？

不是只有一个 label 受 input 变化的影响，我希望第二个标签也对输入的变化使用react并为 运行相同的动画code>.pick-select label 和 .select-label label 一样。

$(document).ready(function() {
  $(".select-all").on("click", function() {
    $(this).is(":checked") ?
      $(".select-input")
      .prop("checked", true)
      .change() :
      $(".select-input")
      .prop("checked", false)
      .change();
  });
  $("input[name='select-check']:checkbox").change(function() {
    if ($(this).is(":checked")) {
      if ($("input[name='select-check']:checkbox:not(:checked)").length == 0) {
        $(".select-all").prop("checked", true);
      }
      $(this)
        .closest(".shrink")
        .addClass("active");
    } else {
      $(".select-all").prop("checked", false);
      $(this)
        .closest(".shrink")
        .removeClass("active");
    }
  });
});

.pick-select {
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  z-index: 999;
}
.shrink {

在我的方法中，当 checkbox.select-input 被选中时，最近的 .selectall-btn 被激活( active 添加到它的 class)。请参阅 CSS 中的 .selectall-btn.active 标签 > span。

$(document).ready(function() {
  $(".select-all").on("click", function() {
    $(this).is(":checked") ?
      $(".select-input")
      .prop("checked", true)
      .change() :
      $(".select-input")
      .prop("checked", false)
      .change();
  });
  $("input[name='select-check']:checkbox").change(function() {
    if ($(this).is(":checked")) {
      // This didn't work; hence I added `:not(.select-all)` to the selector. The
      // `.is()` check should be kept there.
      if (! $(this).is('.select-all') &&
        $("input[name='select-check']:checkbox:not(:checked):not(.select-all)").length == 0) {
        $(".select-all").prop("checked", true);
      }
      $(this)
        .closest(".shrink")
        .addClass("active")
        // This does what you wanted. (see the CSS code)
        .prev('.selectall-btn').addClass('active');
    } else {
      if (! $(this).is('.select-all')) {
        $(".select-all").prop("checked", false);
      }
      $(this)
        .closest(".shrink")
        .removeClass("active")
        // This does what you wanted. (see the CSS code)
        .prev('.selectall-btn').removeClass('active');
    }
  });
});

.pick-select {
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  z-index: 999;
}
.shrink {
  height: 50px;
  width: 50px;
  border: 3px solid;
  position: relative;
  -webkit-transition: all 600ms cubic-bezier(0.19, 1, 0.22, 1);
  -o-transition: all 600ms cubic-bezier(0.19, 1, 0.22, 1);
  transition: all 600ms cubic-bezier(0.19, 1, 0.22, 1);
  -webkit-transform: scale(1);
  -ms-transform: scale(1);
  transform: scale(1);
}
.shrink.active {
  -webkit-transition: all 600ms cubic-bezier(0.19, 1, 0.22, 1);
  -o-transition: all 600ms cubic-bezier(0.19, 1, 0.22, 1);
  transition: all 600ms cubic-bezier(0.19, 1, 0.22, 1);
  -webkit-transform: scale(0.8);
  -ms-transform: scale(0.8);
  transform: scale(0.8);
  border: 2px solid red;
}
.select-label {
  display: inline-block;
  cursor: pointer;
  position: relative;
}
.select-label span {
  display: inline-block;
  position: relative;
  background-color: transparent;
  width: 15px;
  height: 15px;
  transform-origin: center;
  border: 2px solid silver;
  border-radius: 50%;
  vertical-align: -6px;
  margin-right: 10px;
  transition: background-color 150ms,
    transform 350ms cubic-bezier(0.78, -1.22, 0.17, 1.89);
}
input[name="select-check"] {
  display: none;
}
input[name="select-check"]:checked + label span,
.selectall-btn.active label > span {
  background-color: blue;
  border-color: blue;
  transform: scale(1.25);
}
input[name="select-check"]:checked + label span:after,
.selectall-btn.active label > span:after {
  width: 10px;
  background: #fff;
  transition: width 150ms ease 100ms;
}
input[name="select-check"]:checked + label span:before,
.selectall-btn.active label > span:before {
  width: 5px;
  background: #fff;
  transition: width 150ms ease 100ms;
}
