340 CHAPTER 9 ■ PERFORMING FORM VALIDATION WITH REGULAR EXPRESSIONS // Stores the value of the submit button submitVal = $(this).val(), // Determines if the event should be removed remove = false, // Saves the start date input string start = $(this).siblings("[name=event_start]").val(), // Saves the end date input string end = $(this).siblings("[name=event_end]").val(); // If this is the deletion form, appends an action if ( $(this).attr("name")=="confirm_delete" ) { // Adds necessary info to the query string formData += "&action=confirm_delete" + "&confirm_delete="+submitVal; } // If the event is really being deleted, sets // a flag to remove it from the markup if ( submitVal=="Yes, Delete It" ) { remove = true; } // If creating/editing an event, checks for valid dates if ( $(this).siblings("[name=action]").val()=="event_edit" ) { if ( !validDate(start) || !validDate(end) ) { alert("Valid dates only! (YYYY-MM-DD HH:MM:SS)"); return false; } } // Sends the data to the processing file $.ajax({ type: "POST", url: processFile, data: formData, success: function(data) { // If this is a deleted event, removes // it from the markup if ( remove===true ) { fx.removeevent(); }
}); // Fades out the modal window fx.boxout(); // If this is a new event, adds it to // the calendar if ( $("[name=event_id]").val().length==0 && remove===false ) { fx.addevent(data, formData); } }, error: function(msg) { alert(msg); } }); $(".edit-form a:contains(cancel)") .live("click", function(event){...}); }); CHAPTER 9 ■ PERFORMING FORM VALIDATION WITH REGULAR EXPRESSIONS Now save these changes, load http://localhost/ in your browser, <strong>and</strong> then create a new event with bad parameters using the modal window form (see Figure 9-24). 341
