jQuery CSS3自定义美化Checkbox实现代码

效果图：

是不是比默认的好看多了，个人的审美观应该还是可以的。

接下来我们一起来看看实现这款美化版Checkbox的源代码，主要思路是利用隐藏原来的checkbox和radiobox，用一个div来模拟checkbox/radiobox，并使用jQuery来完成选择切换时的动画效果。

先来看看HTML代码：

<div class="wrapper">
  <ul>
   <li>
    <p>Gender:</p>
   </li>
   <li>
    <input type="radio" name="radio-btn" />Male
   </li>
   <li>
    <input type="radio" name="radio-btn" />Female
   </li>
  </ul>
  <ul>
   <li>
    <p>推荐网站:</p>
   </li>
   <li>
    <input type="checkbox" name="check-box" /> <span>何问起</span>

   </li>
   <li>
    <input type="checkbox" name="check-box" /> <span>柯乐义</span>

   </li>
   <li>
    <input type="checkbox" name="check-box" /> <span>hwq2.com</span>

   </li>
   <li>
    <input type="checkbox" name="check-box" /> <span>hovertree.net</span>

   </li>
  </ul>
 </div>

然后我们用jQuery代码来为每一个checkbox和radiobox创建一个div，这个div的classname为check-box和radio-btn。

$("input[name="radio-btn"]").wrap("<div class="radio-btn"><i></i></div>");
$("input[name="check-box"]").wrap("<div class="check-box"><i></i></div>");

那么我们接下来要让原来的checkbox隐藏，同时设置模拟div的样式：

.radio-btn input[type="radio"], .check-box input[type="checkbox"] {
 visibility: hidden;
}

.check-box {
 width: 22px;
 height: 22px;
 cursor: pointer;
 display: inline-block;
 margin: 2px 7px 0 0;
 position: relative;
 overflow: hidden;

 background: linear-gradient(to bottom, rgba(255, 255, 255, 1) 0%, rgba(246, 246, 246, 1) 47%, rgba(237, 237, 237, 1) 100%);

}

.checkedBox {

.checkedRadio {

 -webkit-border-radius: 100%;
 -moz-border-radius: 100%;
 border-radius: 100%;
}
.checkedRadio i {
 background-color: #898A8C;

上面这段CSS3代码就是用样式来自定义div，让div的样式和checkbox和radiobox一样。

最后我们来模拟点击选中和取消选中，这部分也是用jQuery来实现：

$(".radio-btn").on("click", function () {
 var _this = $(this),
  block = _this.parent().parent();
 block.find("input:radio").attr("checked", false);
 block.find(".radio-btn").removeClass("checkedRadio");
 _this.addClass("checkedRadio");
 _this.find("input:radio").attr("checked", true);
});

$.fn.toggleCheckbox = function () {
 this.attr("checked", !this.attr("checked"));
}
$(".check-box").on("click", function () {
 $(this).find(":checkbox").toggleCheckbox();
 $(this).toggleClass("checkedBox");
});/* 何问起 hovertree.com */
