基于事件模型的同域内全局事件监听触发实现
构思：
1、在应用中，由于用了iframe，为了方便各个页面不用window.parent.parent这样的调用考虑利用事件模型对此问题进行解决。
2、应用
$.bindge("eventname",function(event,...){ ...});$.triggerge("eventname",params);/** * 客户端统一事件管理器 */(function($, undefined){ /** * 定义全局事件管理器 */ var _globalEventManagerWin_ = window; var _$globalEventManager = null; while (!_$globalEventManager) { try { if (!_globalEventManagerWin_.closed && _globalEventManagerWin_._$globalEventManager) { _$globalEventManager = _globalEventManagerWin_._$globalEventManager; break; } } catch (e) { // do nothing } if (!_globalEventManagerWin_.closed && _globalEventManagerWin_.parent != null && _globalEventManagerWin_.parent != _globalEventManagerWin_) { _globalEventManagerWin_ = _globalEventManagerWin_.parent; } else if (!_globalEventManagerWin_.closed && _globalEventManagerWin_.opener != null && _globalEventManagerWin_.opener != _globalEventManagerWin_) { _globalEventManagerWin_ = _globalEventManagerWin_.opener; } else { //全局事件管理器 var GlobalEventManager = function(config){ }; //全局事件管理器属性: GlobalEventManager.prototype.$globalEventHandle = $("<_global_event_handle/>"); // GlobalEventManager.prototype.eventTypeCallbackMapping = {}; //全局事件管理器方法: //添加事件监听器 GlobalEventManager.prototype.bind = function(eventType, data, callbackFn){ var _self = this; if(!callbackFn && $.isFunction(data)){ callbackFn = data; data = []; } //压入堆栈 if(!_self.eventTypeCallbackMapping[eventType]){ _self.eventTypeCallbackMapping[eventType] = $.Callbacks("unique"); _self.$globalEventHandle.bind(eventType, data, function(event){ console.log(Array.prototype.slice.call(arguments)); _self.eventTypeCallbackMapping[eventType].fireWith(callbackFn,Array.prototype.slice.call(arguments)); }); } var _whenExceptionRemoveAbleFunction = function(){ try{ callbackFn.apply(callbackFn,arguments); }catch(e){ //console.log('fire bind global event exception: ' + e); _self.eventTypeCallbackMapping[eventType].remove(_whenExceptionRemoveAbleFunction); } }; _self.eventTypeCallbackMapping[eventType].add(_whenExceptionRemoveAbleFunction); }; GlobalEventManager.prototype.trigger = function(eventType, params){ this.$globalEventHandle.trigger(eventType, params) }; /** * 事件管理器全局对象 */ _$globalEventManager = new GlobalEventManager(); _globalEventManagerWin_._$globalEventManager = _$globalEventManager; //循环调度，用以清理全局事件管理器中，已经被回收的对象 //setInterval(function(){ // //},60 * 1000 ); } } //释放引用 _globalEventManagerWin_ = null; var _globalEventCallbacks = {}; $.extend( { triggerGlobalEvent : function(eventType, params) { _$globalEventManager.trigger(eventType, params); }, bindGlobalEvent : function(eventType, data, callbackFn) { _$globalEventManager.bind(eventType, data, callbackFn); } }); $.triggerGE = $.triggerge = $.triggerGlobalEvent; $.bindGE = $.bindge = $.bindGlobalEvent;})(jQuery);
