How Can I Refresh A Detail Select List When My Master Select Changes Using Ajax

I'm looking for some pointers. I have one select list with a list of topics; ).change(function() { // make AJAX call to update the second select list $.ajax({ url: "path/to/your/action", data: $('#TopicDescription').val(), success: function(data){ // do something to your other dropdown// for example if your getting the data back to fill it with from your post method $('#SubTopicDescription').html(data); // you get the point } }); }); CopySolution 2: I asked a similar question and it got closed because it was a a duplicate of this apparently. Here is what I asked Using PHP/SQL - How can I click an item in a list to display another list of items assoicated to the clicked item I use a list of links rather than a drop down select.Anyways I got it working with some help. I have 2 tables. the "list" table (which has ID and listName fields) and a "listitems" table (which has id,itemName, and parent fields). When you click a list the items that have that list as a parent are displayed in another list next to it. Here you go. It has deprecated functions and is sloppy but it wil do for now while I learn more. I'm still a beginner but if I get around to cleaning it up I will edit this.<?phprequire ('./includes/connection.inc.php'); /* AJAX request */if(!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') { $query = sprintf('SELECT * FROM listitems WHERE parent=%d', mysql_real_escape_string($_REQUEST['parent'])); $listitems = mysql_query($query) ordie(mysql_error()); printf('<h3>List %d Items</h3>', $_REQUEST['parent']); while($info = mysql_fetch_array( $listitems )) { echo$info['itemName']."<br />"; } exit; } /* Normal request */?><divid="lists"><h3>Lists</h3><?php$lists = mysql_query("SELECT * FROM lists") ordie(mysql_error()); while($info = mysql_fetch_array( $lists )) { echo'<a href="?parent='.$info['id'].'">'.$info['listName'].'</a><br />'; } ?></div><divid='listitems'><?php$query = sprintf('SELECT * FROM listitems WHERE parent=%d', mysql_real_escape_string($_REQUEST['parent'])); $listitems = mysql_query($query) ordie(mysql_error()); printf('<h3>List %d Items</h3>', $_REQUEST['parent']); while($info = mysql_fetch_array( $listitems )) { echo$info['itemName']."<br />"; } ?></div><scriptsrc="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script><script>jQuery(function($)){ $('#lists').delegate('a', 'click', function(e){ e.preventDefault(); $('#listitems').load($(this).attr('href')) }); } </script>Copy Share Post a Comment for "How Can I Refresh A Detail Select List When My Master Select Changes Using Ajax" Top Question SweetAlert - Change Modal Width?
