282 CHAPTER 8 ■ EDITING THE CALENDAR WITH AJAX AND JQUERY }; }, // GMT, then adjusted for the local timezone, // adjust the offset to ensure a proper date event.setMinutes(event.getTimezoneOffset()); "deserialize" : function(str){...}, "urldecode" : function(str) {...} Ensuring the Event Occurs in the Current Month Your next step is to set up a conditional statement that ensures that only events that belong on the calendar are appended. If both the year and month match between the current calendar month and the event date, you can extract the day of the month using the Date object’s .getDay() method. To work properly with the next step, which adds leading zeroes to single-digit dates, you also need to convert this value to a string, which is accomplished by passing the value to String(). The day of the month needs to have a leading zero to properly match the calendar. For example, if the returned date is only one digit, you prepend a leading zero to the date. Do this by inserting the following bold code: fx = { "initModal" : function() {...}, "boxin" : function(data, modal) {...}, "boxout" : function(event) {...}, // Adds a new event to the markup after saving "addevent" : function(data, formData){ // Converts the query string to an object var entry = fx.deserialize(formData), // Makes a date object for current month cal = new Date(NaN), // Makes a date object for the new event event = new Date(NaN), // Extracts the event day, month, and year date = entry.event_start.split(' ')[0], // Splits the event data into pieces 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; "deserialize" : function(str){...}, "urldecode" : function(str) {...} Appending the Event to the Calendar CHAPTER 8 ■ EDITING THE CALENDAR WITH AJAX AND JQUERY You’re finally ready to append the new event to the calendar. To do so, create a new anchor element, hide it, set its href attribute, and use the title of the event as the link text. Next, set a one-second delay using .delay(1000) and fade in the new event. You can implement this by adding the following code shown in bold: fx = { "initModal" : function() {...}, "boxin" : function(data, modal) {...}, "boxout" : function(event) {...}, // Adds a new event to the markup after saving "addevent" : function(data, formData){ // Converts the query string to an object var entry = fx.deserialize(formData), // Makes a date object for current month cal = new Date(NaN), // Makes a date object for the new event event = new Date(NaN), // Extracts the event day, month, and year date = entry.event_start.split(' ')[0], // Splits the event data into pieces 283
