是不是比預設的好看多了，個人的審美觀應該還是可以的。

接下來我們一起來看看實現這款美化版Checkbox的原始碼。主要思路是利用隱藏原來的checkbox和radiobox，用一個div來模擬checkbox/radiobox，並使用jQuery來完成選擇切換時的動畫效果。

先來看看HTML程式碼：

<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>推薦網站:</p>
            </li>
            <li>
                <input type="checkbox" name="check-box" /> <span>何問起</span>

            </li>
            <li>
                <input type="checkbox" name="check-box" /> <span>柯樂義</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>

然後我們用jQuery程式碼來為每一個checkbox和radiobox建立一個div，這個div的classname為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>");

那麼我們接下來要讓原來的checkbox隱藏，同時設定模擬div的樣式：

.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: -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%);

}
.check-box i {

    position: absolute;

上面這段CSS3程式碼就是用樣式來自定義div，讓div的樣式和checkbox和radiobox一樣。

最後我們來模擬點選選中和取消選中，這部分也是用jQuery來實現：

$(".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");
});/* 何問起 hovertree.com */
