感觉吧，一个博客还是应该有分享的功能的，感觉挺重要的，所以就花了些时间给加上了。
不懂JS真心伤，感谢@陌小雨的帮助。

JS代码

   // TBUI
    window.TBUI = window.TBUI || {}
    TBUI.bd = $('body')
    TBUI.shareimage = TBUI.shareimage || ''
    TBUI.click = 'click'
    $('.sitenav-on').on(TBUI.click, function(){
        TBUI.bd.toggleClass('sitenav-active')
    })
`$('.sitenav-mask').on(TBUI.click, function(){
    TBUI.bd.removeClass('sitenav-active')
})
$('.searchstart-on').on(TBUI.click, function(){
$(this).hide()
$('.searchstart-off').show()
TBUI.bd.addClass('searchform-active')
$('.sinput').focus()
})
$('.searchstart-off').on(TBUI.click, function(){
$(this).hide()
$('.searchstart-on').show()
TBUI.bd.removeClass('searchform-active')
})
/* 分享 */ // SHARE IMAGE TBUI.shareimage = $("#imgshare").attr('src'); TBUI.bd.prepend('<div id="shareimage"><img src="'+%20TBUI.shareimage%20+'" style="display: none;"></div>') // SHARE var share = { url: encodeURIComponent(document.URL), pic: TBUI.shareimage, title: $('.s_title h2').text().length?$('.s_title h2').text():document.title, desc: ' 【'+$('h2.s_title').text() +'】 Mr.Wu博客，关注互联网安全，分享最新的黑客技术、黑客工具、开源漏洞、圈内新闻等！', summary: $('.item-descs p:first').text().length ? $('.item-descs p:first').text().substring(0,100): document.title } $('[etap="share"]').on(TBUI.click, function(){var dom = $(this)
var to = dom.data('share')
var url = ''
switch(to){
case 'qq':
url = 'http://connect.qq.com/widget/shareqq/index.html?url='+share.url+'&title='+share.title+'&desc='+share.desc+'&summary='+share.summary+'&site=dedewp&pics='+share.pic
break;
case 'weibo':
    url = 'http://service.weibo.com/share/share.php?title='+share.desc+'&url='+share.url+'&source=bookmark&pic='+share.pic
    break;
case 'douban':
url = 'http://www.douban.com/share/service?image='+share.pic+'&href='+share.url+'&name='+share.title+'&text='+share.desc
break;
case 'qzone':
url = 'http://sns.qzone.qq.com/cgi-bin/qzshare/cgi_qzshare_onekey?url='+share.url+'&title='+share.title+'&desc='+share.desc+'&pics='+share.pic+'&summary='+share.summary
break;

}
if( !dom.attr('href') && !dom.attr('target') ){
dom.attr('href', url).attr('target', '_blank')
}
`
})

分享html代码

注意事项

以上为本博客最终代码，要实际应用的话需要对JS代码中几处样式进行相应修改。
需要给文章图片加上id="imgshare"属性。
如果还需要其他平台的分享，可以对照代码进行相应添加。
