问题 I am using the MarkerClusterer library for Google Maps API V3 to group nearby markers into a single marker. When the user clicks on the cluster marker, a div appears beside that cluster marker. Now I want to make it such that after clicking on the cluster marker, to close the div that popped up, he can click on the map. Problem: After adding a google.maps.event.addListener(map, 'click', function(){}) on the map, when the user clicks on the cluster marker to open the popup div, nothing happens

问题 I have created an infobox using google maps api v3 and infoBox from the maps utility library . The infobox has overflow-y data. Scrolling works exactly as expected on IE, FF, Chrome and Safari desktop. Scrolling does not work at all, however, in mobile Safari. It's almost as if the infoBox doesn't detect a touch to start scrolling. I've created this jsfiddle to demonstrate the problem. As you can see (in the iOS simulator or on an iOS device), the mouseenter, touchstart, mouseleave and

问题 I want to add a Listener event to each generated marker, so that when you click a marker you are redirected to the permalink url. With the code below the permalink value is the same for every marker(it get's the last value). I've read about closure problems and that seems to be what I'm having. I don't really get the examples I've looked at though. Can somebody take a look at my code and point me in the right direction? Any help is greatly appreciated! downloadUrl("http://localhost/map

问题 I use plupload on a metronic bootstrap framework. On desktop it's working fine but on smartphone or tablet, my browse button is not opening the window to select files. <div class="col-md-8"> <div id="engine"></div> <div id="dev_uploader"> <div id="filelist"></div> </div> <a id="addImg" class="btn btn-bg btn-block"><i class="fa fa-plus"></i> add attachement</a> here is the plupload script : jQuery(function() { var uploader = new plupload.Uploader({ runtimes : 'html5,flash,silverlight,gears',

问题 I'm writing a Firefox extension, This is my XUL (no problem there) <?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE overlay SYSTEM "chrome://locale/myDtd.dtd"> <page id="overlay" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul" xmlns:xhtml="http://www.w3.org/1999/xhtml"> <script type="application/x-javascript" src="chrome://addon/content/test.js" /> </page> And here is the problematic part of the Javascript test.js window.addEventListener("load", function(event) {

问题 I press S, followed by D, on my keyboard, and release S. Why does the following code trigger a key down event for D once again, after I release S? Is there some way to find out that the second down event for D was caused by a key up of another key? function handler(event) { if (!event.repeat) console.log(event.code, event.type); } window.addEventListener('keydown', handler); window.addEventListener('keyup', handler); Output: KeyS keydown - S pressed KeyD keydown - D pressed KeyS keyup - S

问题 I am working on a Firefox extension and I want to know when a page initiates a xhr request, I saw a few codes but they were pretty big, is there any simple sample to achieve this? I am testing this code : function TracingListener() { //this.receivedData = []; } TracingListener.prototype = { originalListener: null, receivedData: null, // array for incoming data. onDataAvailable: function(request, context, inputStream, offset, count) { var binaryInputStream = CCIN("@mozilla.org

问题 I have an element with a title attribute (i.e., a tooltip), wrapped in some container: <div id="foo"> <input type="text" title="A tooltip" /> </div> and I attach a "mousemove" event listener on the container and stop event propagation: document.getElementById('foo').addEventListener( 'mousemove', function(e) { e.stopPropagation() }, false ) This combination of stopping propagation of "mousemoves" on the container now prevents the tooltip from showing up for the inner textbox, in Firefox 2 and

问题 How can my JavaScript detect if an event is available? I'm aware of some great event-compatibility tables, but I need to use feature detection, not browser-sniffing plus a lookup table. Specifically, my JS makes great use of the DOM mutation events ( DOMNodeInserted and DOMSubtreeModified ) -- which work great in all browsers except (of course) Internet Explorer. So, how would I detect if a browser supports DOMNodeInserted ? 回答1: If you just want to check if the browser supports mutation

问题 Let's say we want to make a webapp feel like a native app with "Add to Home Screen." One of the first steps is to disable the default scrolling. Easy, right? // window or document window.addEventListener("touchmove", function(event) { // no more scrolling event.preventDefault(); }, false); That's all fine and dandy until you add overflow-scrolling to the mix. To be precise, on iOS it would be -webkit-overflow-scrolling: touch . /* #scrollable happens to be a ul */ #scrollable { overflow-y:
