    if(name=='' || name==0 

     && email=='' || email==0 

     && cemail=='' || cemail ==0 

     && password=='' || password==0 

     && cpassword=='' || cpassword==0) { 

     document.getElementById("onsubmitErr").innerHTML 
                = "All fields arerequired"; 

       return false; 
      } 

    return true; 
}
