var m = document.form1.emailid.value

        var cnt=0,spc=0,dot=0;

        for(var i=1;i<=m.length;i++)

        {

                if(m.charAt(i)=="@") cnt++;

                if(m.charAt(i)==" ") spc++;

                if(m.charAt(i)==".") dot++;

        }

        lnm=m.length

        if(cnt==0||cnt>1||spc!=0||dot==0 ||lnm<=2 )        {alert("Please Enter Valid E-mail Id ");document.form1.emailid.focus();return false;        }
