Accessing drop down value from popup...

Hi,

I have a drop down menu (say named 'popname') with a list of values. I have a go button which causes a popup to appear when clicked. My question is, how can i access the value chosen in that drop down menu in the popup?

Thanks
Neville

You'll have to use Javascript...
This is off the top of my head:

Code:

var popList = document.frmName.popName;
alert(popList.options[popList.selectedIndex].value);

Hi,

I tried the code. Let me show you both the source codes.

index.html
------------------------------------

Code:

<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script langauge="javascript">
function openpopup(varpopurl,varwidth,varheight)
{
	var dimensions = 'width=' + varwidth + ',height=' + varheight;
	winpops=window.open(varpopurl,"",dimensions)
}
</script>
</head>

<body>
<form name="mainform">
<select name="stores">
<option>a</option>
<option>b</option>
<option>c</option>
</select>
<a href="javascript:openpopup('stores.html',300,300)">GO</a>
</form>
</body>
</html>

------------------------------------

stores.html (the popup page)
------------------------------------

Code:

<html>
<head>
<title>Stores</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body>
<script language="javascript">
var popList = document.mainform.stores;
alert(popList.options[popList.selectedIndex].value);
</script>
</body>
</html>

------------------------------------

This doesnt seem to work. I basically need to access the value currenty selected in the index.html from the stores.html.

Thanks

Try this instead:
var popList = window.opener.document.mainform.stores;

Accessing value in PHP query...

Hi,

Thanks for the previous help. I am able to access the drop down value however i need to insert that value into a php query, which i am getting stuck with.

Code:

$query = mysql_query("SELECT * FROM table WHERE place = 'popList.options[popList.selectedIndex].value'");

This is ofcourse not gonna work, anyway this explains exactly what i wanna do.

Thanks in advance!

Ah, well, that changes everything... indeed the code in your post above wont work.

I was afraid that was the real issue =) Both code samples in your original post were named "HTML" so I figured it was strictly Javascript.

The solution to this is somewhat easier than what you have already.

On your parent page (index.html), I would change the link to be:

Code:

<a href="javascript:openpopup('stores.php?s='+popList.optio  ns[popList.selectedIndex].value,300,300)">GO</a>

Then on your popup, stores.php, use the line:

PHP Code:


		
			
 $query = mysql_query("SELECT * FROM table WHERE place = '{$_GET['s']}'");

Again this is off the top of my head and may require some tweaking.

Accessing value in PHP query...

Try out this one.
You just fire the form and get value posted like below.It may help.

<form name="mainform" method="post">
<select name="stores" onChange="document.mainform.submit();">
<option>a</option>
<option>b</option>
<option>c</option>
</select>
</form>

<?
$stores = $_POST["stores"];
?>

Get posted value in button element,
<button onClick="openpopup('stores.html?value=<?= $stores ?> ',300,300)">Go</button>

Your code works fine.

Thanks a lot..

Perhaps this should move back to PHP. I originally misunderstood the context of the question.
Could a Javascript forum Mod make the move please?
