It will disable the next and previous arrows based on the out of bounds dates you specify with mindate and maxdate when you configure the calendar. Requires YUI dom and a namespace called your_app. <br /> <br />1) attach an onRender event when you configure the calendar and before you call render <br /> <br /><code>calendar.renderEvent.subscribe(YAHOO.your_app.calendar().initArrows, calendar);</code> <br /> <br />2) add the following function: <br /> <br /><code> <br />YAHOO.your_app.calendar = function() { <br /> <br /> var addDays = function(date, days) { <br /> return YAHOO.widget.DateMath.add(date, YAHOO.widget.DateMath.DAY, days); <br /> }; <br /> <br /> var showPreviousArrow = function(cal) { <br /> return showArrow(cal, cal.toDate(cal.cellDates[0]), 1); <br /> }; <br /> <br /> var showNextArrow = function(cal) { <br /> return showArrow(cal, cal.toDate(cal.cellDates[cal.cellDates.length-1]), -1); <br /> }; <br /> <br /> var showArrow = function(cal, startingDate, step) { <br /> if (!cal.isDateOOM(startingDate)) { //ie not overlapping <br /> return !cal.isDateOOB(addDays(startingDate, (-1 * step))); <br /> } <br /> for (var i=0; (i * step) < 7; i += step) { //iterate forwards for previous month check, backwards for next month check <br /> var date = addDays(startingDate, i); <br /> if (!cal.isDateOOM(date)) { //shortcut exit; as soon as we find an in month date we can supress the arrow <br /> return false; <br /> } else if (!cal.isDateOOB(date)) { <br /> return true; <br /> } <br /> } <br /> return false; <br /> }; <br /> <br /> return { <br /> initArrows: function(type, args, cal) { <br /> if (!showPreviousArrow(cal)) { <br /> hideArrow(cal, cal.Style.CSS_NAV_LEFT); <br /> } <br /> <br /> if (!showNextArrow(cal)) { <br /> hideArrow(cal, cal.Style.CSS_NAV_RIGHT); <br /> } <br /> } <br /> }; <br />}; <br /></code> Mon, 03 Mar 2008 20:57:33 GMT http://snippets.dzone.com/posts/show/5198 robd (Rob Dupuis) http://snippets.dzone.com/posts/show/1367 <code> <br />// Extension to Ajax allowing for classes of requests of which only one (the latest) is ever active at a time <br />// - stops queues of now-redundant requests building up / allows you to supercede one request with another easily. <br /> <br />// just pass in onlyLatestOfClass: 'classname' in the options of the request <br /> <br />Ajax.currentRequests = {}; <br /> <br />Ajax.Responders.register({ <br /> onCreate: function(request) { <br /> if (request.options.onlyLatestOfClass && Ajax.currentRequests[request.options.onlyLatestOfClass]) { <br /> // if a request of this class is already in progress, attempt to abort it before launching this new request <br /> try { Ajax.currentRequests[request.options.onlyLatestOfClass].transport.abort(); } catch(e) {} <br /> } <br /> // keep note of this request object so we can cancel it if superceded <br /> Ajax.currentRequests[request.options.onlyLatestOfClass] = request; <br /> }, <br /> onComplete: function(request) { <br /> if (request.options.onlyLatestOfClass) { <br /> // remove the request from our cache once completed so it can be garbage collected <br /> Ajax.currentRequests[request.options.onlyLatestOfClass] = null; <br /> } <br /> } <br />}); <br /></code> Mon, 06 Feb 2006 22:34:12 GMT http://snippets.dzone.com/posts/show/1367 matth (Matthew)
