使用Radio Button和JS进行CSS转换

Question

使用我的jQuery代码，我可以从.item获取属性，但我的css转换不起作用。您可以将.item替换为.item-tile来查看预期的转换。

如何让我的CSS过渡到我的jQuery代码？

＆＃13;

＆＃13;

$(".item-wrap").on("click", ".item", function() {
  var itemColor = $(this)
    .find(".icon")
    .css("background-color");
  $(".category-color").css("background-color", itemColor);
  return false;
});

＆＃13;

.item-wrap {
  display: flex;
}

.icon {
  margin: 0px 5px 0px 5px;
  position: relative;
  height: 35px;
  width: 35px;
  border-radius: 50%;
}

.item-wrap .item {
  position: relative;
}

.item-wrap .item .radio-button {
  opacity: 0;
  position: absolute;
  top: 0;
  left: 0;
  bottom: 0;
  left: 0;
  height: 100%;
  width: 100%;
  margin: 0;
  z-index: 999;
  cursor: pointer;
}

.item-wrap .item .item-tile {
  -webkit-transition: -webkit-transform 300ms ease;
  transition: -webkit-transform 300ms ease;
  -o-transition: transform 300ms ease;
  transition: transform 300ms ease;
  transition: transform 300ms ease, -webkit-transform 300ms ease;
}

.item-wrap .item .radio-button:checked+.item-tile {
  border: 2px solid #079ad9;
  -webkit-transform: scale(1.1, 1.1);
  -ms-transform: scale(1.1, 1.1);
  transform: scale(1.1, 1.1);
}

.category-color {
  height: 50px;
  width: 50px;
}

＆＃13;

Answer 1

使用:focus代替:checked。

<强>为什么吗

只是因为在你的jQuery代码中你返回false并且阻止了无线电输入的默认behvavior所以它无法检查。

$(".item-wrap").on("click", ".item", function() {
  $("#text-preview").text($(this).find(".item-text").text());
  var path = $(this)
    .find("#item-path")
    .attr("d");
  var pathb = $(this)
    .find("#item-path")
    .attr("d");
  var pathc = $(this)
    .find("#item-path")
    .attr("d");
  $("#path-preview").attr("d", path);
  $("#path-preview").attr("d", pathb);
  $("#path-preview").attr("d", pathc);
  var itemColor = $(this)
    .find(".icon")
    .css("background-color");
  $(".category-color").css("background-color", itemColor);
  return false;
});

.item-wrap {
  display: flex;
}
.item-tile {
  display: -webkit-box;
  display: -ms-flexbox;
  display: flex;
  margin: 15px;
  background: white;
  -webkit-box-align: center;
  -ms-flex-align: center;
  align-items: center;
  height: 50px;
  border-radius: 10px;
  -webkit-box-shadow: 3px 4px 3px -1px rgba(245, 245, 245, 1);
  box-shadow: 3px 4px 3px -1px rgba(245, 245, 245, 1);
}

.item-tile label {
  flex: 0;
  padding: 0px 5px 0px 5px;
}

.icon {
  margin: 0px 5px 0px 5px;
  position: relative;
  height: 35px;
  width: 35px;
  border-radius: 50%;
}

.item-wrap .item {
  position: relative;
}

.item-wrap .item .radio-button {
  opacity: 0;
  position: absolute;
  top: 0;
  left: 0;
  bottom: 0;
  left: 0;
  height: 100%;
  width: 100%;
  margin: 0;
  z-index: 999;
  cursor: pointer;
}

.item-wrap .item .item-tile {
  -webkit-transition: -webkit-transform 300ms ease;
  transition: -webkit-transform 300ms ease;
  -o-transition: transform 300ms ease;
  transition: transform 300ms ease;
  transition: transform 300ms ease, -webkit-transform 300ms ease;
}

.item-wrap .item .icon svg {
  width: 3rem;
  height: 3rem;
}

.item-wrap .item .radio-button:focus+.item-tile {
  border: 2px solid #079ad9;
  -webkit-transform: scale(1.1, 1.1);
  -ms-transform: scale(1.1, 1.1);
  transform: scale(1.1, 1.1);
}

顺便说一下，我没有看到这个return false的实用程序，所以如果你删除它，你的代码就可以了：

$(".item-wrap").on("click", ".item", function() {
  $("#text-preview").text($(this).find(".item-text").text());
  var path = $(this)
    .find("#item-path")
    .attr("d");
  var pathb = $(this)
    .find("#item-path")
    .attr("d");
  var pathc = $(this)
    .find("#item-path")
    .attr("d");
  $("#path-preview").attr("d", path);
  $("#path-preview").attr("d", pathb);
  $("#path-preview").attr("d", pathc);
  var itemColor = $(this)
    .find(".icon")
    .css("background-color");
  $(".category-color").css("background-color", itemColor);
});

.item-wrap {

}
