POgetJSON call fails unless single stepped
text
Body
copied!<p>I have a application that has a home page w/ a form w/ check boxes; the chk-bxs represent column-data to return from a MySQL db. </p> <p>The behavior I’m trying to achieve is:</p> <ol> <li>User checks / unchecks boxes on home page</li> <li>User clicks link to page that will run the query</li> <li>Server receives the check boxes states through a getJSON call, triggered by the unload of the home page. PHP loads $_SESSION[] w/ chk-bxs states</li> <li>Server then process the link call using the data in $_SESSION[] to determine what column data to return and display in result in a table</li> </ol> <p>I CAN achieve this IF I put a break point at the last member assign of the getJSON call and single stepping it. Without the single-step, the getJSON call doesn’t seem to happen; so the chk-bxs values don’t get transmitted to the server. Can anyone explain this behavior? Is there a better way to approach the problem? Any thoughts would be appreciated. </p> <p>This is the code in the head section of the index.php file that calls the function that will do the getJSON call:</p> <pre><code>$(window).on('beforeunload', function(){ indexFormUnload(); // this saves the state of the SELECT check-boxes }); </code></pre> <p>This is the code that constructs the getJSON call - it resides in a separate file included in the index.php file:</p> <pre><code>function indexFormUnload(){ var ckBxValues = $(":input").serializeArray(); $.getJSON("ajaxJQ_server.php", // server page called by jquery { // Data sent via ajaxJQ "callingForm": "index", "callingElementID" : null, "locStorage": ckBxValues, "callingState": "unload", "tableName": null } ); } </code></pre>
