var mai = mailids;
var val = true;

var dot = mai.lastIndexOf(".");
var ext = mai.substring(dot,mai.length);
var at = mai.indexOf("@");
var dom = dot - at;
var sp = mai.indexOf(" ");

if(dom >= 4 && at >1 && sp == -1)
{
for(var i=0; i<arr.length; i++)
{
if(ext == arr[i])
{
val = true;
break;
}
else
{
val = false;
}
}
if(val == false)
{
alert("Your maild "+mai+" is not corrrrect");
return false;
}
}
else
{
alert("Your maild "+mai+" is not correct");
return false;
}

return true;
}

Here we have explained with a form
a)Creating the form
<form name="test" onSubmit="return checkMailId(test.mailf.value)">
<input name=mailf type=text>
<input type=submit value=test>
</form>

b)Copy the code in to your page.

c)Things will work. The important portion is the onSubmit call in the form. "onSubmit = return checkMailId(test.mailf.value)". We call the method checkMaiId with the form fields value as the variable.

d)If the mailid check is true form action willl take place, else alert will be done.

hope that helps you, it took a quick google search to find
