As a blogger when you want to host java script files, you want to get help from free .js hosting provider like google sites.But here the problem is bandwidth limitations.If you can host java script files into blogger you can get unlimited bandwidth for your .js files.

So if you want to host your .js files with unlimited bandwidth use the code below.

<script type='text/javascript'>

//<![CDATA[

PASTE YOUR JAVASCRIPT CODE HERE

//]]>

</script>

If you can't understand above code look at the example below.

This is the code when you host your java script file into another hosting account.

<script type='text/javascript'>
var thumbnail_mode = &quot;float&quot; ;
summary_noimg = 230;
summary_img = 140;
img_thumb_height = 170;
img_thumb_width = 300;
</script>

<script src='http://keerthiset2.110mb.com/excerpt.js' type='text/javascript'/>

Now when you host your java script file into blogger it should change like this :

<script type='text/javascript'>
var thumbnail_mode = &quot;float&quot; ;
summary_noimg = 230;
summary_img = 140;
img_thumb_height = 170;
img_thumb_width = 300;
</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>

Now you are done.
