问题 The following problems: I need to simulate a double-click on a div element. I need to use/handle MS Internet Explorer 11. I cannot change the source code of the target site. My solution so far: I use C# and SHDocVw.InternetExplorer and mshtml I can fire "click" events al right, they show up in all handlers When trying to simulate the double-click: the "ondoubleclick" event gets triggered. the el.addEventListener('dblclick', handler); does NOT get triggered To reduce the complexity of the

问题 I have a hook that listens to the window.resize event. I wish to only listen to and update when window.innerWidth changes. I wish to ignore changes to window.innerHeight since this gets triggered when opening the soft keyboard. The problem is that the mediaSize is stored in my Redux Store causing the app to re-render when the soft keyboard opens. My code triggers on both window.innerWidth and window.innerHeight changes, how can I change this behaviour? My hook import { useState, useEffect }

问题 This question is similar to the one asked here. However in that case it seems that the poster's ultimate purpose was actually to select a paragraph of text, and they were able to find a work-around which did not involve clicking. Like the user in the above question I initially thought that it would be possible to simulate a triple-click by calling the click method three times. new Actions(driver) .moveToElement(svgElement, posX, posY) .click() .click() .click() .perform() However, this doesn

问题 I'm creating a client-side dynamic blog engine. Now I need a event system to handle many actions from DOM elements and the engine. Such as the engine is loading a article,user is switching a theme... And I don't want to use a library to do this. So far I've done is using a list to store callbacks for a event . But I want each callback works with different objects.Like the DOM event. I may add an id-like property to each object, and store (id,callbacks) in a event.I feel it's not so good.When

问题 I have a listener attached to resize event on window object. Deeper in my code, I have some input fields. To avoid some issues on android devices, I’d like to prevent resize listeners from being fired when an input field is focused (android device resize browser window when opening keyboard, unlike IOS). main.js window.addEventListener(‘resize’, () => { // Some stuff here }); someFile.js field.addEventListener(‘input’, () => { // Here I want to disable the resize event only once }); I came

问题 I have a web app that's running a 60FPS loop forever and I sometimes want to check whether a key is down now. So I made var keydown = [] window.addEventListener("keydown", function(e){keydown[e.keyCode]=true}) window.addEventListener("keyup", function(e){keydown[e.keyCode]=false}) function loop() { if(keydown[17]) console.log("Control is down.") if(keydown[71]) console.log("F is down.") } setInterval(loop, 16) The problem is that if the user presses control+F to search the page, then when

问题 I'm applying some animations to a navbar through JS but I'm probably repeating myself a lot in the event listening part. But I can't find a way to improve it. Is there a way I can use a loop or something in order to listen to all these events without writing a code block for each one? let headerHome = document.querySelector('.headerHome'); let headerPlayground = document.querySelector('.headerPlayground'); let headerAbout = document.querySelector('.headerAbout'); headerHome.addEventListener(
