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 WebRTC Video Constraints Not Working I'm trying to get a lower resolution from the webcam na… Remove Content From Table And Reformat The Table I want to do My page is displaying data of the table in be… HTML Table With Fixed Header And Fixed Leading Columns With Knockout Controls In The Header And First Column I have a HTML table which can be customized by the user: E… How Do I Make A Menu Pop Up When The User Clicks The Menu Button?
