How to load only summary of post without loading full page
<p>On my blog, on home page I am showing summary of posts instead of full posts. I was thinking it was loading only summary which contains a image and some lines from the post, but when I tested it on a Speed-Testing website, I saw that it is loading full page, every image and then hiding the images on other content . It is affecting my page load speed. Is there any way so only the summary will load.</p>

<pre><code> &lt;/script&gt;
&lt;script type='text/javascript'&gt;
  var thumbnail_mode = &amp;quot;no-float&amp;quot; ; 
  summary_noimg = 430; 
  summary_img = 500; 
  img_thumb_height = 100; 
  img_thumb_width = 120; 
&lt;/script&gt;
&lt;script type='text/javascript'&gt;
  //&lt;![CDATA[ 
  function removeHtmlTag(strx,chop){ 
    if(strx.indexOf("&lt;")!=-1) 
    { 
      var s = strx.split("&lt;"); 
      for(var i=0;i&lt;s.length;i++){ 
        if(s[i].indexOf("&gt;")!=-1){ 
          s[i] = s[i].substring(s[i].indexOf("&gt;")+1,s[i].length); 
        } 
      } 
      strx = s.join(""); 
    } 
    chop = (chop &lt; strx.length-1) ? chop : strx.length-2; 
    while(strx.charAt(chop-1)!=' ' &amp;&amp; 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&gt;=1) { 
      imgtag = '&lt;span style="float:left; padding:0px 10px 5px 0px;"&gt;&lt;img src="'+img[0].src+'" width="'+img_thumb_width+'px" height="'+img_thumb_height+'px"/&gt;&lt;/span&gt;'; 
      summ = summary_img; 
    } 
    var summary = imgtag + '&lt;div&gt;' + removeHtmlTag(div.innerHTML,summ) + '&lt;/div&gt;'; 
    div.innerHTML = summary; 
  } 
  //]]&gt;&lt;/script&gt;
</code></pre>

<p>This is the code which I have used to make summary.</p>
