代碼相當(dāng)簡(jiǎn)潔、簡(jiǎn)單易懂，就不多廢話了。

直接奉上代碼：

<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-type" content="text/html" charset="utf-8">
        <title>js簡(jiǎn)單選項(xiàng)卡</title>
        <script type="text/javascript" src="js/demo.js"></script>

    </head>
    <body>
        <div class="tabs" id="tabs">
            <h2 class="tabs-nav clearfix">
                <a href="javascript:;" class="on">首頁(yè)</a>
                <a href="javascript:;">技術(shù)</a>
                <a href="javascript:;">生活</a>
                <a href="javascript:;">作品</a>
            </h2>
            <div style="clear:both;"></div>
            <p class="tabs-content">首頁(yè)</p>
            <p class="tabs-content_hide">技術(shù)</p>
            <p class="tabs-content_hide">生活</p>
            <p class="tabs-content_hide">作品</p>
        </div>

    </body>
<footer></footer>
</html>

------demo.js---------------

復(fù)制代碼代碼如下:

window.onload=function(){
    tabs("tabs","mouseover");
}
function tabs(id,trigger){
    var tabBtn = document.getElementById(id).getElementsByTagName("h2")[0].getElementsByTagName("a");
    var tabsContent = document.getElementById(id).getElementsByTagName("p");
    for(var i=0;i<tabBtn.length;i++){
        tabBtn[i].index = i;
        if(trigger=='mouseover'){
            tabBtn[i].onmouseover=function(){
                clearClass();
                this.className="on";
                showContent(this.index);
            }
        }
        function showContent(n){
            for (var i=0; i<tabsContent.length ;i++) {
                tabsContent[i].index = i;
                tabsContent[i].className = "tabs-content_hide";
        }
        tabsContent[n].className="tabs-content";
    }
        function clearClass(){
            for(var i=0;i<tabBtn.length;i++){
                tabBtn[i].className="";
            }
        }
    }
}
