我使用此javascript在blogger / BlogSpot中显示带缩略图的最新帖子
<script>
function showlatestpostswiththumbs(t){document.write('<ul class="recent-posts-container">');for(var e=0;e<posts_no;e++){var r,n=t.feed.entry[e],i=n.title.$t;if(e==t.feed.entry.length)break;for(var o=0;o<n.link.length;o++){if("replies"==n.link[o].rel&&"text/html"==n.link[o].type)var l=n.link[o].title,m=n.link[o].href;if("alternate"==n.link[o].rel){r=n.link[o].href;break}}var u;try{u=n.media$thumbnail.url}catch(h){s=n.content.$t,a=s.indexOf("<img"),b=s.indexOf('src="',a),c=s.indexOf('"',b+5),d=s.substr(b+5,c-b-5),u=-1!=a&&-1!=b&&-1!=c&&""!=d?d:"http://2.bp.blogspot.com/-C3Mo0iKKiSw/VGdK808U7rI/AAAAAAAAAmI/W7Ae_dsEVAE/s1600/no-thumb.png"}var p=n.published.$t,f=p.substring(0,4),g=p.substring(5,7),v=p.substring(8,10),w=new Array;if(w[1]="Jan",w[2]="Feb",w[3]="Mar",w[4]="Apr",w[5]="May",w[6]="Jun",w[7]="Jul",w[8]="Aug",w[9]="Sep",w[10]="Oct",w[11]="Nov",w[12]="Dec",document.write('<li class="recent-posts-list">'),1==showpoststhumbs&&document.write('<a href="'+r+'"><img class="recent-post-thumb" src="'+u+'"/></a>'),document.write('<div class="recent-post-title"><a href="'+r+'" target ="_top">'+i+"</a></div>"),"content"in n)var A=n.content.$t;else if("summary"in n)var A=n.summary.$t;else var A="";var k=/<\S[^>]*>/g;if(A=A.replace(k,""),1==post_summary)if(A.length<summary_chars)document.write(A);else{A=A.substring(0,summary_chars);var y=A.lastIndexOf(" ");A=A.substring(0,y),document.write(A+"...")}var _="",$=0;document.write('<br><div class="recent-posts-details">'),1==posts_date&&(_=_+w[parseInt(g,10)]+" "+v+" "+f,$=1),1==readmorelink&&(1==$&&(_+=" | "),_=_+'<a href="'+r+'" class="url" target ="_top">Read more</a>',$=1),1==showcommentslink&&(1==$&&(_+=" <br> "),"1 Comments"==l&&(l="1 Comment"),"0 Comments"==l&&(l="No Comments"),l='<a href="'+m+'" target ="_top">'+l+"</a>",_+=l,$=1),document.write(_),document.write("</div>"),document.write("</li>")}document.write("</ul>")}
</script>
<script type="text/javascript">
var posts_no = 5;
var showpoststhumbs = true;
var readmorelink = true;
var showcommentslink = false;
var posts_date = true;
var post_summary = true;
var summary_chars = 70;
</script>
<script src="/feeds/posts/default?orderby=published&alt=json-in-script&callback=showlatestpostswiththumbs"></script>
<a style="font-size: 9px; color: #CECECE; margin-top: 10px;" href="http://helplogger.blogspot.com/2014/11/5-cool-recent-post-widgets-for-blogger.html" rel="nofollow">Recent Posts Widget</a>

此脚本显示基于summary_chars值的帖子摘要。
所以我想在跳转之前显示帖子摘要，有人可以帮帮我吗？
