358 CHAPTER 10 ■ EXTENDING JQUERY Initializing the Plugin on a Set of Elements The plugin is now included in the application, so you can call the .dateZoom() method on a set of elements. The next set of changes requires that you modify init.js, so open that file now. Begin by changing the default fontsize value to 13px, and then add the .dateZoom() method to the chain of methods on the set of elements selected with the "li a" string. As already indicated, you implement these changes by adding modifying init.js, as shown in the bold code that follows: jQuery(function($){ var processFile = "assets/inc/ajax.inc.php", fx = {...} // Set a default font-size value for dateZoom $.fn.dateZoom.defaults.fontsize = "13px"; // Pulls up events in a modal window and attaches a zoom effect $("li a") .dateZoom() .live("click", function(event){ // Stops the link from loading view.php event.preventDefault(); // Adds an "active" class to the link $(this).addClass("active"); // Gets the query string from the link href var data = $(this) .attr("href") .replace(/.+?\?(.*)$/, "$1"), // Checks if the modal window exists and // selects it, or creates a new one modal = fx.checkmodal(); // Creates a button to close the window $("") .attr("href", "#") .addClass("modal-close-btn") .html("×") .click(function(event){ // Removes event fx.boxout(event); }) .appendTo(modal);
}); // Loads the event data from the DB $.ajax({ type: "POST", url: processFile, data: "action=event_view&"+data, success: function(data){ // Displays event data fx.boxin(data, modal); }, error: function(msg) { alert(msg); } }); $(".admin-options form,.admin") .live("click", function(event){...}); // Edits events without reloading $(".edit-form input[type=submit]") .live("click", function(event){...}); $(".edit-form a:contains(cancel)") .live("click", function(event){...}); }); CHAPTER 10■ EXTENDING JQUERY Save these changes, reload http://localhost/ in your browser, and then hover over an event title to see the dateZoom plugin in action (see Figure 10-1). 359
