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 $('#SubTopicDescription').html(data); // you get the point } }); }); Copy Solution 2: I asked a similar question and it got closed because it was a a duplicate of this apparently. Here is what I asked Using PHP/SQL - How can I click an item in a list to display another list of items assoicated to the clicked item I use a list of links rather than a drop down select. Anyways I got it working with some help. I have 2 tables. the "list" table (which has ID and listName fields) and a "listitems" table (which has id,itemName, and parent fields). When you click a list the items that have that list as a parent are displayed in another list next to it. Here you go. It has deprecated functions and is sloppy but it wil do for now while I learn more. I'm still a beginner but if I get around to cleaning it up I will edit this. <?php require ('./includes/connection.inc.php'); /* AJAX request */ if(!empty($_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) or die(mysql_error()); printf('<h3>List %d Items</h3>', $_REQUEST['parent']); while($info = mysql_fetch_array( $listitems )) { echo $info['itemName']."<br />"; } exit; } /* Normal request */ ?> <div id="lists"> <h3>Lists</h3> <?php $lists = mysql_query("SELECT * FROM lists") or die(mysql_error()); while($info = mysql_fetch_array( $lists )) { echo '<a href="?parent='.$info['id'].'">'.$info['listName'].'</a><br />'; } ?> </div> <div id='listitems'> <?php $query = sprintf('SELECT * FROM listitems WHERE parent=%d', mysql_real_escape_string($_REQUEST['parent'])); $listitems = mysql_query($query) or die(mysql_error()); printf('<h3>List %d Items</h3>', $_REQUEST['parent']); while($info = mysql_fetch_array( $listitems )) { echo $info['itemName']."<br />"; } ?> </div> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script> <script>jQuery(function($)){ $('#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 After Float Images, Need To Be Centered In Div I've tried many times and it couldn't work at all. … Making A Proper Image Capture Of Current Screen Using Jquery Or PHP Or Convert Div To Pdf I write some code for to convert svg to inline svg and take… Force Download For Blob Created With FileWriter In JavaScript HTML5 introduces the FileWriter class.
