Access html content loaded with jQuery's load() function

[OYcarmel]

I'm a bit confused by how jQuery ajax works. I'm trying to create a customer management system (CMS) with jQuery and php.I want to give the user the opportunity to create a car. Let's say he must define a "car name" and check some options in a checkbox list. At the same page i give the user the opportunity to add or delete some options. This addingand deleting happens with jQuery and ajax. When a user add an option, i call a php page (addOption.php) that processes the option and add's it to the database. If the ajax call is successful, i reload the options in a div using the ajax load() function. Who calls a php page (reloadOptions.php) that reads out the options from the database and constructs them into a list of check-boxes.All this works fine. The problem occurs when i try to check what check-boxes are checked.(difficult sentence here )It seems that the data don't exist in the page source. I think this happens because of the asynchronous working of ajax. And i really need the options to create the car!Finally, my question is how can i access that options data? And if you can't, is there stilla way where you can access that data?What do you think about my approach to handle the cms system? Good / Bad / omg / ...Below are some code blocks i use:The page index.php : jQuery/ajax that processes the options and the html code\[code\] //At the start i load the options in$('.options').load('./php/OptionsReload.php');$("#FormOptions").submit(function(e) { $.ajax({ type: "POST", url: "./php/addOption.php", data: $(e.target).serialize(), dataType: "json", success: function(data) { $('.options').load('./php/reloadOptions.php'); } }); return false; });..................//Form where you can add the option <form id="FormOptions"> <input type="text" name="optionName" /> <input type="submit" name="submitOption" value="http://stackoverflow.com/questions/12751839/Add option" /></form>...................... //Div where i show the options to the user <form name="formChecks" method="post" enctype="multipart/form-data"> <div class="options"> //Content loaded with jQuery </div> </form>\[/code\]The page addOption.php : code that adds the option to the database\[code\] //Database connect...return mysql_query("INSERT INTO options(option) VALUES('". $POST_['optionName'] ."');");\[/code\]The page reloadOptions.php : code that constructs the html with the options \[code\]<select name="mydropdown"> <?php $options = ...... connect with DB and select all the options while($row = mysql_fetch_assoc($options)) { echo ("<option value='" . $row['Id'] . "'>" . $row['optionName'] . "</option>"); } ?></select>\[/code\]Thanks in advance,Bert
