258 CHAPTER 7 ■ ENHANCING THE USER INTERFACE WITH JQUERY "initModal" : function() { // If no elements are matched, the length // property will be 0 if ( $(".modal-window").length==0 ) { // Creates a div, adds a class, and // appends it to the body tag return $("") .addClass("modal-window") .appendTo("body"); } else { // Returns the modal window if one // already exists in the DOM return $(".modal-window"); } }, // Adds the window to the markup and fades it in "boxin" : function(data, modal) { // Creates an overlay for the site, adds // a class and a click event handler, then // appends it to the body element $("") .hide() .addClass("modal-overlay") .click(function(event){ // Removes event fx.boxout(event); }) .appendTo("body"); }, // Loads data into the modal window and // appends it to the body element modal .hide() .append(data) .appendTo("body"); // Fades in the modal window and overlay $(".modal-window,.modal-overlay") .fadeIn("slow"); // Fades out the window and removes it from the DOM "boxout" : function(event) { // If an event was triggered by the element // that called this function, prevents the // default action from firing if ( event!=undefined )
}; } { } event.preventDefault(); // Removes the active class from all links $("a").removeClass("active"); // Fades out the modal window, then removes // it from the DOM entirely $(".modal-window") .fadeOut("slow", function() { $(this).remove(); } ); CHAPTER 7 ■ ENHANCING THE USER INTERFACE WITH JQUERY Next, you need to modify the callback function that fires on a successful execution of $.ajax() when clicking an event title to call fx.boxin; you do so by adding the line of bold code in the listing that follows: // Pulls up events in a modal window $("li>a").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.initModal(); // Creates a button to close the window $("") .attr("href", "#") .addClass("modal-close-btn") .html("×") .click(function(event){ // Removes modal window fx.boxout(event); }) .appendTo(modal); 259
