<html> <head> <script type="text/javascript"> $(function() { alert('document ready'); $('#b').on('click', function(){ alert('you clicked button'); $('#s').load(test.php); }); }); </script> </head> <body> <select name="s" id="s"> <?php $server = 'localhost'; //localhost usual name of server if apache/linux. $login = 'root'; $pword = ''; $dbname = 'item'; mysql_connect($server,$login,$pword) or die($connect_error); //or die(mysql_error()); mysql_select_db($dbname) or die($connect_error); ?> <?php $query = "select * ajax_categories"; $results = mysql_query($query); while ($rows = mysql_fetch_assoc(@$results)) {?> <option value="<?php echo $rows['id'];?>"><?php echo $rows['category'];?></option> <?php }?> </select> <input type = "button" value="go" name="b" id="b"> and test.php code :
<?php $query = "select * ajax_categories"; $results = mysql_query($query); while ($rows = mysql_fetch_assoc(@$results)) {?> <option value="<?php echo $rows['id'];?>"><?php echo $rows['category'];?></option> <?php }?> it shows alert combobox doesnt reloading new database content
try changing :
$('#s').load(test.php); to :
$('#s').load('test.php'); string literals important.
