分享到QQ空间、新浪微博、腾讯微博的代码！
给网页加上分享代码，借助网友的力量推广网站，目前已经很流行了
以下是网页代码
QQ空间分享代码如下：
<a href="javascript:void(0);" onclick="window.open('http://sns.qzone.qq.com/cgi-bin/qzshare/cgi_qzshare_onekey?url='+encodeURIComponent(document.location.href));return false;" title="分享到QQ空间"><img src="http://qzonestyle.gtimg.cn/ac/qzone_v5/app/app_share/qz_logo.png" alt="分享到QQ空间" /></a>
新浪微博分享代码如下：
<script type="text/javascript">document.write('<iframe frameborder="0" scrolling="no" src="http://hits.sinajs.cn/A1/weiboshare.html?url=%url%&appkey=&type=3" width="16" height="16"></iframe>'.replace(/%url%/,encodeURIComponent(location.href)));</script>
腾讯微博分享代码如下：
<a href="javascript:void(0)" onclick="postToWb();" class="tmblog"><img src="http://v.t.qq.com/share/images/s/weiboicon16.png"></a> <script type="text/javascript">
function postToWb(){
var _t = encodeURI(document.title);
var _url = encodeURI(document.location);
var _appkey = encodeURI("appkey");//你从腾讯获得的appkey
var _pic = encodeURI('');//（列如：var _pic='图片url1|图片url2|图片url3....）
var _site = '';//你的网站地址
var _u = 'http://v.t.qq.com/share/share.php?title='+_t+'&url='+_url+'&appkey='+_appkey+'&site='+_site+'&pic='+_pic;
window.open( _u,'转播到腾讯微博', 'width=700, height=680, top=0, left=0, toolbar=no, menubar=no, scrollbars=no, location=yes, resizable=no, status=no' );
}
</script>
QQ朋友社区分享代码如下：
<a href="javascript:void(0);" onclick="window.open('http://sns.qzone.qq.com/cgi-bin/qzshare/cgi_qzshare_onekey?to=pengyou&url='+encodeURIComponent(document.location.href));return false;" title="分享到朋友社区"><img src="http://qzonestyle.gtimg.cn/ac/qzone_v5/app/qzshare/xy-icon.png" alt="分享到朋友社区" /></a>
这里发个自己DIY的分享代码，喜欢的可以拿去用，预览图如下
图片素材在压缩包里，代码内容如下，保存为js文件即可，压缩包里也有现成的。
