it all depends on what you are trying to do, I mean you can't just
copy it, you must send it, the usual way is with a form, or using XHR,
or an iframe, or a script tag, or an image.
<form id="form" action="php_script.php" method="get">
<input id="name" name="name" type="hidden" value="" />
<input name="submit" type="submit" value="submit" />
</form>
<script type="text/javascript">
//name = 'JACK';
document.getElementById('name').value = name;
document.getElementById('form').submit();
</script>
if you dont want the page to change, then submit to an iframe
<iframe src="" name="iframe" style="visibility:hidden" width="0"
height="0"></iframe>
<form id="form" action="php_script.php" method="get" target="iframe">
<input id="name" name="name" type="hidden" value="" />
<input name="submit" type="submit" value="submit" />
</form>
<script type="text/javascript">
//name = 'JACK';
document.getElementById('name').value = name;
document.getElementById('form').submit();
</script>
XHR is too boring to write out, google AJAX.
<iframe src="" id="iframe" style="visibility:hidden" width="0"
height="0"></iframe>
<script type="text/javascript">
//name = 'JACK';
document.getElementById('iframe').src = 'php_script.php?name=' + name;
</script>
<img src="" id="img" style="visibility:hidden" width="0" height="0"/>
<script type="text/javascript">
//name = 'JACK';
document.getElementById('img').src = 'php_script.php?name=' + name;
</script>
then there's the script include in the heade
<script type="text/javascript">
name = 'JACK';
document.write('<script type="text\/javascript" src="php_script.php?
name="'+name+'><\/script>');
</script>
take your pick. Of course I should be in bed so all this could be
rubbish!
