dom-events

问题 I have this scenario, where when parent element is clicked, it flips to show a child element with different colours. Unfortunately, when the user clicks on one of the colours, the 'click' event on parent is also triggered. How can I stop the event trigger on parent when the child is clicked? Possible solutions I am wondering: CSS ? Append pointer-events : none class to the parent when the child is clicked. However, this would mean that the parent will need to be cleansed of the pointer-events

问题 This question already has answers here : Getting the list of voices in speechSynthesis (Web Speech API) (11 answers) Closed last month . Related to this text to speech question, I have the following code: First of all, I am not sure if this is the best way to write the code, because it is initializing, and then setting a listener to "call itself". (seems a little bit hacky). Second, although the listeners got "notified", the voices.length is still 0 . Nothing really happens with an array of

问题 Let me start by saying I am trying to play a mp3 file whenever the player collides with a wall, simple enough and done. But I wish to have another sound file play when the player hits another wall. I have tried using both <audio> tag in the html file, than playing it in Javascript: var sound = document.getElementById("TheHtml5Tag"); Still the same issue, only one sound can be played, the next sound won't play untill the first one is finished.

问题 Take the following fiddle. It contains a parent div with 3 child divs. A click-listener is attached to the parent div and should throw alerts with the mouse position relative to the parent div: const parent = document.getElementById('main'); parent.addEventListener('click', handleMouseClick); function handleMouseClick(e) { alert(e.offsetX, e.offsetY); } What I expect: Click on any of the child divs and get the click position relative to the parent div (#main). What actually happens: OffsetX/Y

问题 I'm currently using Owl Carousel 2.0.0-beta.2.4 in development to keep the carousel centered and loop the items which works nicely. For some reason the cloned items that Owl generates when setting loop: true doesn't seem to fire on click. You will see in the example I've put together below that every other item alerts the click when fired but if the item has been cloned it doesn't seem to register the click event. JSFiddle HTML: <div id="multiple-carousel" class="carousel-style owl-carousel">
