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。
复制代码代码如下:
<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>Favorite music:</p>
</li>
<li>
<input type="checkbox" name="check-box" /> <span>Pop music</span></p><p> </li>
<li>
<input type="checkbox" name="check-box" /> <span>Rock music</span></p><p> </li>
<li>
<input type="checkbox" name="check-box" /> <span>Rap music</span></p><p> </li>
<li>
<input type="checkbox" name="check-box" /> <span>Hiphop music</span></p><p> </li>
</ul>
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。
复制代码代码如下:
$(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：
复制代码代码如下:
.radio-btn input[type="radio"], .check-box input[type="checkbox"] {
visibility: hidden;
}
复制代码代码如下:
.check-box {
width: 22px;
height: 22px;
cursor: pointer;
display: inline-block;
margin: 2px 7px 0 0;
position: relative;
overflow: hidden;
box-shadow: 0 0 1px #ccc;
-webkit-border-radius: 3px;
-moz-border-radius: 3px;
border-radius: 3px;
background: rgb(255, 255, 255);
background: -moz-linear-gradient(top, rgba(255, 255, 255, 1) 0%, rgba(246, 246, 246, 1) 47%, rgba(237, 237, 237, 1) 100%);
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%, rgba(255, 255, 255, 1)), color-stop(47%, rgba(246, 246, 246, 1)), color-stop(100%, rgba(237, 237, 237, 1)));
background: -webkit-linear-gradient(top, rgba(255, 255, 255, 1) 0%, rgba(246, 246, 246, 1) 47%, rgba(237, 237, 237, 1) 100%);
background: -o-linear-gradient(top, rgba(255, 255, 255, 1) 0%, rgba(246, 246, 246, 1) 47%, rgba(237, 237, 237, 1) 100%);
background: -ms-linear-gradient(top, rgba(255, 255, 255, 1) 0%, rgba(246, 246, 246, 1) 47%, rgba(237, 237, 237, 1) 100%);
background: linear-gradient(to bottom, rgba(255, 255, 255, 1) 0%, rgba(246, 246, 246, 1) 47%, rgba(237, 237, 237, 1) 100%);
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#ffffff, endColorstr=#ededed, GradientType=0);
border: 1px solid #ccc;
}
.check-box i {
background: url(css/check_mark.png) no-repeat center center;
position: absolute;
left: 3px;
bottom: -15px;
width: 16px;
height: 16px;
opacity: .5;
-webkit-transition: all 400ms ease-in-out;
-moz-transition: all 400ms ease-in-out;
-o-transition: all 400ms ease-in-out;
transition: all 400ms ease-in-out;
-webkit-transform:rotateZ(-180deg);
-moz-transform:rotateZ(-180deg);
-o-transform:rotateZ(-180deg);
transform:rotateZ(-180deg);
}
.checkedBox {
-moz-box-shadow: inset 0 0 5px 1px #ccc;
-webkit-box-shadow: inset 0 0 5px 1px #ccc;
box-shadow: inset 0 0 5px 1px #ccc;
border-bottom-color: #fff;
}
.checkedBox i {
bottom: 2px;
-webkit-transform:rotateZ(0deg);
-moz-transform:rotateZ(0deg);
-o-transform:rotateZ(0deg);
transform:rotateZ(0deg);
}
/*Custom radio button*/
.radio-btn {
width: 20px;
height: 20px;
display: inline-block;
float: left;
margin: 3px 7px 0 0;
cursor: pointer;
position: relative;
-webkit-border-radius: 100%;
-moz-border-radius: 100%;
border-radius: 100%;
border: 1px solid #ccc;
box-shadow: 0 0 1px #ccc;
background: rgb(255, 255, 255);
background: -moz-linear-gradient(top, rgba(255, 255, 255, 1) 0%, rgba(246, 246, 246, 1) 47%, rgba(237, 237, 237, 1) 100%);
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%, rgba(255, 255, 255, 1)), color-stop(47%, rgba(246, 246, 246, 1)), color-stop(100%, rgba(237, 237, 237, 1)));
background: -webkit-linear-gradient(top, rgba(255, 255, 255, 1) 0%, rgba(246, 246, 246, 1) 47%, rgba(237, 237, 237, 1) 100%);
background: -o-linear-gradient(top, rgba(255, 255, 255, 1) 0%, rgba(246, 246, 246, 1) 47%, rgba(237, 237, 237, 1) 100%);
background: -ms-linear-gradient(top, rgba(255, 255, 255, 1) 0%, rgba(246, 246, 246, 1) 47%, rgba(237, 237, 237, 1) 100%);
background: linear-gradient(to bottom, rgba(255, 255, 255, 1) 0%, rgba(246, 246, 246, 1) 47%, rgba(237, 237, 237, 1) 100%);
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#ffffff, endColorstr=#ededed, GradientType=0);
}
.checkedRadio {
-moz-box-shadow: inset 0 0 5px 1px #ccc;
-webkit-box-shadow: inset 0 0 5px 1px #ccc;
box-shadow: inset 0 0 5px 1px #ccc;
}
.radio-btn i {
border: 1px solid #E1E2E4;
width: 10px;
height: 10px;
position: absolute;
left: 4px;
top: 4px;
-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：
复制代码代码如下:
$(".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);
});
复制代码代码如下:
$.fn.toggleCheckbox = function () {
this.attr(checked, !this.attr(checked));
}
$(.check-box).on(click, function () {
$(this).find(:checkbox).toggleCheckbox();
$(this).toggleClass(checkedBox);
});
这段代码可以让选中和取消选中时产生一点小小的动画。
