javascript - Can't submit button on load event -

i created example work jquery 1.7.2 , onload event click onload event nobody needs click.

here example:http://jsfiddle.net/fztd5/32/

<script> window.onload=function(){  document.getelementbyid("formbutton").submit(); } </script> <form action="page/site" method="post">     <input type="hidden" name="name" value="value" />     <input type="submit" id="formbutton" /> </form> 

i tried

document.getelementbyid("formbutton").click(); 

please can me?

you have 2 mistakes: 1- form's method 'postt' , submit's invocation on button instead form element. try this

<script type="text/javascript"> $(document).ready(function(){     $("#form").submit() }) </script> <form action="page/site" method="post" id="form">     <input type="hidden" name="name" value="value" />     <input type="submit" id="formbutton" /> </form>

if redirect same page , want avoid endless submit loop, try

<script type="text/javascript"> $(document).ready(function(){     if (window.location.search.indexof("auto_submited") == -1){         $("#form").attr('action', $("#form").attr('action') + "?auto_submited=1")         $("#form").submit()     } })  </script> <form action="page/site" method="post" id="form">     <input type="hidden" name="name" value="value" />     <input type="submit" id="formbutton" /> </form> 

it's better check in server-side, being possible javascript
