How to customize addthis plugin

Hey you need not to be PHP expert or javascript expert to customize addthis plugin. Just add this bit of snippet in the <head> tag

<script type=”text/javascript”>
var addthis_config = {
services_compact: ‘facebook, twitter, stumbleupon, digg, orkut, email, more’,

so keep adding rhe social networking sites names with comma separated and you are done.

validating textarea using javascript/dhtml

So many times we need to validate textarea to limit users from entering more charachters

Here is the code which is tested  in IE for validating textarea for 255 charachters.

/*copy this code in head tag */

<script language = “Javascript”>
* Author : suresh kumar

function taLimit(taObj) {
if (taObj.value.length==maxL) return false;
return true;

function taCount(taObj,Cnt) {
if (objVal.length>maxL) objVal=objVal.substring(0,maxL);
if (objCnt) objCnt.innerText=maxL-objVal.length;
return true;
function createObject(objId) {
if (document.getElementById) return document.getElementById(objId);
else if (document.layers) return eval(“document.” + objId);
else if (document.all) return eval(“document.all.” + objId);
else return eval(“document.” + objId);

/*copy this in body */

<font> Maximum Number of characters for this text box is 255.<br>
<textarea onKeyPress=”return taLimit(this)” onKeyUp=”return taCount(this,’myCounter’)” name=”Description” rows=7 wrap=”physical” cols=40>
You have <B><SPAN id=myCounter>255</SPAN></B> characters remaining
for your description…</font>
