  • 0

I have 2 frames of php files, first is call topFrame and bottom is called mainFrame. In the topFrame I have a php file with a dropdown value, onchange I would want to reload this frame with another php file.

Below is my code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<title>RATEMASTER</title>

<script type="text/javascript">

function showsupli(sta)
{

alert ("sta");
if (sta == 'Yes')
{
window.open('ratesupli.php,'topFrame');
}
}

</script>

</head>
<body>
<?
echo "<form name='f1'>";

echo "<table width='730' border='0' align='center' cellpadding='0' cellspacing='1'>";
echo "  <tr>";
echo "    <td><span class='style3'>Suplimentry Invoice</span></td>";

echo "    <td>";
echo "<select name='supli' onchange=\"showsupli(this.value);\"><option value=0>No</option>";
  echo "<option value=1>Yes</option>";
echo "</select>";// Closing of list box
echo "</td>";
echo "  </tr>";

echo "</table>";

echo "</form>";
?>
</body>
</html>

    The problem is your option values are 1 and 0, but in your Javascript you look for Yes.

    Change to:

    if (sta == '1')

    The selected value of a <select> is the selected <option> value, not the text.

    You also have a syntax error, you forgot to close the quote after ratesupli.php, use:

    window.open('ratesupli.php','topFrame');
