To prevent it from being set in the first place, you can return false on the keydown event handler, thus preventing the event from propagating any further. I wrote the example below using jQuery, but you can use the same function when binding traditionally. Though it’s important to validate on the server-side as well, client-side … Read more
I’m surprised it’s not mentioned, there’s also event.repeat: document.addEventListener(‘keydown’, (e) => { if (e.repeat) return; console.log(e.key); }); This will only fire once per each keypress, since event.repeat turns true after holding the key down. https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key#keyboardevent_sequence
For those looking for a practical solution, see: How to find event listeners on a DOM node when debugging or from the JavaScript code? EventListenerList was in some old draft of DOM 3 Events and was long removed from the spec. As far as I know, at least Gecko still doesn’t have anything like this … Read more
setTimeout is compatible with all browsers since 1996. You should avoid the evaluation of “functionName()” and instead do: setTimeout(functionName,5000) UPDATE: If you initially expect a variable passed to the function and none when in the timeout, you need to do this instead: setTimeout(function() { functionName() },5000) However you are calling the onload incorrectly, so you … Read more
If your target isn’t Opera 9 or lower and IE 9 or lower you can use css attribute pointer-events: none. I found it the best way just to ignore iframe. I add class with this attribute to iframe in onMouseDown event and remove in onMouseUp event. Works perfect for me.
I’ve been struggling with this issue. I wanted a reference to another window, so I was issuing a: otherWinRef = window.open(“”,”OtherWindow”); However when I issue this command, the browser will switch focus to the OtherWindow. I thought this could be addressed by doing this: otherWinRef = window.open(“”,”OtherWindow”); window.focus(); but the window.focus() has no effect. I … Read more
If you’re just needing some testing on event firing and catching, this is how I do it. For ensuring that a certain event gets fired ($emit-ed or $broadcast-ed), a spy is the way to go. You need a reference to the scope that will be calling the $emit or $broadcast, and then just to do … Read more
It seems to me like you could just check for !stream.paused.
Have you tried any of these? onMouseDown onMouseEnter onMouseLeave onMouseMove onMouseOut onMouseOver onMouseUp SyntheticEvent it also mentions the following: React normalizes events so that they have consistent properties across different browsers. The event handlers below are triggered by an event in the bubbling phase. To register an event handler for the capture phase, append Capture … Read more
In the Microsoft model you must set the event’s cancelBubble property to true. window.event.cancelBubble = true; In the W3C model you must call the event’s stopPropagation() method. event.stopPropagation(); Here’s a cross-browser solution if you’re not using a framework: function doSomething(e) { if (!e) e = window.event; e.cancelBubble = true; if (e.stopPropagation) e.stopPropagation(); }
