此代码对我有用：

<!-- facebook -->
<img src="[YOUR_FACEBOOK_PIC]" alt="Share on Facebook" onclick="window.open('https://www.facebook.com/sharer/sharer.php?u='+encodeURIComponent('[YOUR_PAGE_URL]'),'facebook-share-dialog','width=626,height=436'); return false;">

<!-- twitter -->
<img src="[YOUR_TWITTER_PIC]" alt="Share on Twitter" onclick="javascript:window.open('https://twitter.com/share?text=[SOME_TEXT_TO_PREPOLUTATE_TWEET]&amp;url=[YOUR_PAGE_URL]','Twitter-dialog','width=626,height=436'); return false;">

<!-- google+ -->
<img src="[YOUR_GOOGLE_PIC]" alt="Share on Google Plus" onclick="window.open('https://plus.google.com/share?url=[YOUR_PAGE_URL]','Google-dialog','width=626,height=436'); return false;">

只需替换括号之间的文字，不要忘记url编码所有文本进入url以避免问题。

Just replace the text between brackets, and don't forget to "url encode" all the text that goes in the url to avoid issues.

它不需要任何SDK的SDK。

And it doesn't need the SDK for any of them.

以下是每个参考官方文档：

Here are references to the official documentation for each of them:

• Facebook （你可以请参阅 URL重定向部分）


• Twitter （你也可以使用 https://twitter.com/intent/tweet ，如 here ）


• Google+ （在共享链接部分下）

• Facebook (you can see it under the URL redirection section)
• Twitter (you could also use https://twitter.com/intent/tweet as described here)
• Google+ (under Share Link section)
