Hi today i will explain you how to filter out inappropriate words from being updated or send from your website.This is simple javascript.

badwords.js
Contains javascript code. If you want add some more words in bad_words_array

var bad_words_array=new Array("dog","badword-2","badword-3");
function badwords(txt)
{
var alert_arr=new Array;
var alert_count=0;
var compare_text=txt;
var total = bad_words_array.length;
var matches = 0;

for( var i = 0; i < total; i++ )
{
if(compare_text.indexOf(bad_words_array&#91;i&#93;) > -1)
{
var message=1;
return message;
break;
}
}
}

index.html
Contains javascript and HTML code. The form calling Message() function.

<script type=">text/javascript" src="badwords.js"></script>
<script type=">text/javascript">
function Message()
{
var textbox_val=document.form.textbox.value;
if(textbox_val=="")
{
alert("Please enter a message");
return false;
}
bwords=badwords(textbox_val);
if(bwords>0)
{
alert("Your message contains some bad words please remove it.");
document.form.textbox.focus();
return false;
}
}
</script>
<form action="send.php" method="post"onsubmit="return Message();" name="form">
<textarea name="textbox"></textarea>
<input type="submit" value=" Submit "/>
</form>

I have fixed couple of bugs in this script. This is working like a charm now.
