问题 It is possible to detect an event with Google Maps V3 API, for instance (ex 1) : google.maps.event.addListener('drag', function(event) { $("#latD").val(event.latLng.lat()); $("#longD").val(event.latLng.lng()); }); or (ex 2) google.maps.event.addListener(markerDep, 'drag', function(event) { $("#latD").val(event.latLng.lat()); $("#longD").val(event.latLng.lng()); }); here, I specified an instance of a Marker. According to Google Maps API Specification, one can create a listener on a particular

问题 This is the code that works properly: bonzo.aug({ bind: function (event, handler) { if (this[0].attachEvent) this[0].attachEvent('on'+event, handler); else this[0].addEventListener(event, handler); }, unbind: function (event, handler) { if (this[0].detachEvent) this[0].detachEvent('on'+event, handler); else this[0].removeEventListener(event, handler); }, once: function (event, handler) { function doOnce(e) { bonzo(this).unbind(event, doOnce); handler.call(this, e); } this.bind(event, doOnce);

问题 I have a class method which defines the event listeners. Let us use the following code snippet for simplicity. function bindEvents() { document.querySelector('button').addEventListener('click', (e) => { console.log('clicked!'); }); } // Initial event binding bindEvents(); // Rebind events at some point for dynamically created elements bindEvents(); <button type="button">Click</button> Everything works fine when using bindEvents() only once, however for example calling it again in ajax

问题 I have more than one scroll function like this: FIRST $(document).scroll(function(){ if(!$(".hotel-search-box").length){ return false; } var y = $(this).scrollTop(); if (y > $(".hotel-search-box").offset().top) { $('.sticky-checkin').show(); } else { $('.sticky-checkin').hide(); } }); SECOND $(document).scroll(function() { if (!$("#aniStickyNav").length) { return false; //Check if the element exist } var y = $(this).scrollTop(); if (y > $(".after-scroll-sticky").offset().top+$(".hotel-search

问题 I am trying to express what I understood from reading some articles about dom0 event model in javascript .If there is a mistake in it ,please correct me. In dom0 model,an event handler can be attached to an element .Only one handler can be attached.When the event occurs,the browser calls that event handler. There are two ways of doing this 1.Inline model The handler is added as an attribute of the element.For example a link element (ie <a> ) has an attribute called onclick .We add a function

问题 I have this code jQuery('#parent').on('click', jQuery('#fileInput'), function (e) { jQuery(e.target).attr('data-fileurl', ''); jQuery('#parent').on('change', jQuery('#fileInput'), function (e) { usefulFunction(jQuery(e.target); } } The idea is to detect if cancel was chosen on file browse, and it succeeds at that. The problem is if I click it again, then it will run the .on('chance') twice and thus run usefulFunction . Each click adds a change event handler. usefulFunction should only be run

问题 The onblur event in javascript is triggered when the element loses focus. The onkeydown Occurs on an element that has the focus when a key is pressed down and occurs periodically until the key is released. If I want to validate a date field, the onkeydown event concerns 9 and 13 (enter and tab key). But when I press the enter key, then I receive duplicate alert message. Of course in this case we have two tests, onblur and onkeydown event. this is the html code : <html:text onblur="return
