Passing drop down list variable to php without submit button

Hi
I have a simple drop down list.
upon user choosing an option I wish to refresh the same page and pass that chosen value to php. without using submit button

I am new to php and even newer to php.

can anyone please help.
This is my code.
how.

<SELECT NAME="countries" SIZE="1"
ONBLUR="if (selectedIndex > 0) { text.value = item(selectedIndex).value;window.location.reload(); }"
>
                          <OPTION VALUE="Please select country">Please select country</OPTION>
                          <OPTION VALUE="Argentina">Argentina</OPTION>
                          <OPTION VALUE="Australia">Australia</OPTION>
                          <OPTION VALUE="Austria">Austria</OPTION>

Code (markup):

.....
</SELECT>


I have found this snippet that I think I should use but don't know how

Make your java call the php script with something like

yourscript.php3?var1=value1&var2=value2

and you will access $var1 and $var2 in your php script.:

Thanks for your time.
p.s. I have this question listed in php, but I think this is a javascript question really.

 

Hi
So far I have managed to get the value of the chosen list using this script:

<script type="text/javascript">
	function showSelected(val){
		document.getElementById
('selectedResult').innerHTML = "The selected number is - " 
+ val;
	}
</script>

<div id='selectedResult'></div>

<select name='test' onChange='showSelected(this.value)'>
	<option value='1'>one</option>
	<option value='2'>two</option>
</select>

Code (markup):

Now what I need to do is using refresh or hidden form pass the value to the php.
Easier said that done.
Any ideas please guys.

 

job done.
