Hello Friends how are you..Hope you all fine.
Here my question is regarding not allowing the special charecters
in the email.I have taken the allowed charecters and not allowed charecters.
its working fine but i have to take only allowed charecters and other than
this charecters should not be allowed.So please help me out how to solve this by removing the notallowed charecters

function CheckValidity(textarea)
{
//alert("key--------"+window.event.keyCode);
var key;
var keychar;
if (window.event)
key = window.event.keyCode;
else if (event)
{
key = event.which;
}
else
return true;

keychar = String.fromCharCode(key);
keychar = keychar.toLowerCase();
var allowedChars = "abcdefghijklmnopqrstuvwxyz1234567890@,_.-";
var notAllowedChars = "~`!#$%^&*()+=|\\\"\/';:?";

if((allowedChars.indexOf(keychar) greaterthan -1) || key == 13 ){

return ;
}
else {
var temp = textarea.value ;
for(i=0;i lessthan temp.length;i++){
var tempkeychar = temp.charAt(i);
if(notAllowedChars.indexOf(tempkeychar) greaterthan -1){
// alert("after charecter----"+notAllowedChars.indexOf(tempkeychar));
document.forms[0].email.value = temp.substr(0,i)+temp.substr(i+1,temp.length);
//alert("before charecter----"+temp.substr(0,i));
return;
}
}
}
}
