284 CHAPTER 8 ■ EDITING THE CALENDAR WITH AJAX AND JQUERY } }, edata = date.split('-'), // Extracts the calendar month from the H2 ID cdata = $("h2").attr("id").split('-'); // Sets the date for the calendar date object cal.setFullYear(cdata[1], cdata[2], 1); // Sets the date for the event date object event.setFullYear(edata[0], edata[1], edata[2]); // Since the date object is created using // GMT, then adjusted for the local timezone, // adjust the offset to ensure a proper date event.setMinutes(event.getTimezoneOffset()); // If the year and month match, start the process // of adding the new event to the calendar if ( cal.getFullYear()==event.getFullYear() && cal.getMonth()==event.getMonth() ) { // Gets the day of the month for event var day = String(event.getDate()); } // Adds a leading zero to 1-digit days day = day.length==1 ? "0"+day : day; // Adds the new date link $("") .hide() .attr("href", "view.php?event_id="+data) .text(entry.event_title) .insertAfter($("strong:contains("+day+")")) .delay(1000) .fadeIn("slow"); "deserialize" : function(str){...}, "urldecode" : function(str) {...} ■ Note The data variable is undefined as of right now. You’ll remedy this in the next section. Now, back in the click event handler for the Submit button, modify the success callback of the $.ajax() function to execute fx.addevent() by using the following bold code:
Edits events without reloading $(".edit-form input[type=submit]").live("click", function(event){ }); // Prevents the default form action from executing event.preventDefault(); // Serializes the form data for use with $.ajax() var formData = $(this).parents("form").serialize(); // Sends the data to the processing file $.ajax({ type: "POST", url: processFile, data: formData, success: function(data) { // Fades out the modal window fx.boxout(); // Adds the event to the calendar fx.addevent(data, formData); }, error: function(msg) { alert(msg); } }); CHAPTER 8 ■ EDITING THE CALENDAR WITH AJAX AND JQUERY Save this file and reload http://localhost/. Bring up the event creation form and create a new event with the following information: • Event Title: Addition Test • Event Start: 2010-01-09 12:00:00 • Event End: 2010-01-09 14:00:00 • Event Description: This is a test of the dynamic addition of new events to the calendar. Submitting the form causes the modal window to fade out; a second later, the new event title will fade in on the calendar in the proper place (see Figure 8-2). 285
