javascript - js click onpage load based on referrer -

i need js clicked when page load based on referrer. when user came fixed domain name, form auto clicked. else nothing.

example: need when user came www.example.com or example.com or example.com/anypage/ in mysite.com/userinfo/ ... form automatically submitted. if not came example.com .. nothing happned.

when use without referrer code au submit.. works , click .. click.. click.. on every load...and continuously clicked...

<script type="text/javascript">       document.getelementbyid("sendit").submit(); </script> 

then try use referrer code... after add referrer code.. not work again.. can do??

<script type="text/javascript"> if (document.referrer == ("http://aweber.com" || "http://www.aweber.com")) {       document.getelementbyid("sendit").submit(); } </script> 

i use method:

<script type="text/javascript"> $( document ).ready(function() {    if (document.referrer == "www.aweber.com") {     $("#sendit").submit();   } else { /* nothing */ } });  </script> 

any idea???

in line:

if (document.referrer == ("http://aweber.com" || "http://www.aweber.com")) { 

you attempting using javascript assignment technique instead of comparing result of document.referrer.

your statement should be:

if ((document.referrer == "http://aweber.com") || (document.referrer = "http://www.aweber.com")) {
