| Adding Auto ‘Read More’ with Thumbnail Posted: 22 Jan 2013 01:36 AM PST Here’s a nice widget that you may add to your Blogger site which I found. It’s an update that was created by Lasantha Bandara, and this will automatically create a post summary with thumbnail. Below are the steps: 1. Go to Blogger Dashboard > Template > Edit HTML. 2. Click Expand Widget Templates. 3. Search for </head> tag. 4. Add this code before </head> tag: <script type='text/javascript'> summary_noimg = 250; summary_img = 200; img_thumb_height = 150; img_thumb_width = 150; </script> <script type='text/javascript'> //<![CDATA[ function removeHtmlTag(strx,chop){ if(strx.indexOf("<")!=-1) { var s = strx.split("<"); for(var i=0;i<s.length;i++){ if(s[i].indexOf(">")!=-1){ s[i] = s[i].substring(s[i].indexOf(">")+1,s[i].length); } } strx = s.join(""); } chop = (chop < strx.length-1) ? chop : strx.length-2; while(strx.charAt(chop-1)!=' ' && strx.indexOf(' ',chop)!=-1) chop++; strx = strx.substring(0,chop-1); return strx+'...'; } function createSummaryAndThumb(pID){ var div = document.getElementById(pID); var imgtag = ""; var img = div.getElementsByTagName("img"); var summ = summary_noimg; if(img.length>=1) { imgtag = '<span style="float:left; padding:0px 10px 5px 0px;"><img src="'+img[0].src+'" width="'+img_thumb_width+'px" height="'+img_thumb_height+'px"/></span>'; summ = summary_img; } var summary = imgtag + '<div>' + removeHtmlTag(div.innerHTML,summ) + '</div>'; div.innerHTML = summary; } //]]> </script> Note: You may change the values below with your own preference: summary_noimg : number of characters shown when there's no image. summary_img : number of characters shown when there's an image. img_thumb_height : height of post thumbnails. img_thumb_width : width of post thumbnails. 5. Look for this <data:post.body/> 6. Replace the code above with this: <b:if cond='data:blog.pageType != "static_page"'> <b:if cond='data:blog.pageType != "item"'> <div expr:id='"summary" + data:post.id'><data:post.body/></div> <script type='text/javascript'>createSummaryAndThumb("summary<data:post.id/>");</script> </b:if> </b:if> <b:if cond='data:blog.pageType == "item"'><data:post.body/></b:if> <b:if cond='data:blog.pageType == "static_page"'><data:post.body/></b:if> <b:if cond='data:blog.pageType != "static_page"'> <b:if cond='data:blog.pageType != "item"'> <div style='float:right;margin-right:10px;margin-top:5px;'> <a expr:href='data:post.url'>Read More</a> </div> </b:if> </b:if> 7. Save template Note: Always perform a backup first before doing any customizations on your template.
