CSS3和jQuery实现的自定义美化Checkbox

大家好，又见面了，我是全栈君，今天给大家准备了Idea注册码。

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。

当然我们可以在这里查看DEMO演示。

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

}
.check-box i {

    position: absolute;

 .radio-btn {

    display: inline-block;
    float: left;

.checkedRadio i {

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 */
