Nov 07, 2024 pm 01:02 PMSimulating Background Tab Opening to Avoid Chrome Flashing
In JavaScript, opening a new tab while maintaining focus on the current tab can be achieved using the following code:
open('http://example.com/'); focus();
However, this method causes a brief flicker of the new tab in Chrome. To avoid this issue, consider using the following approach:
Simulating Key Combinations
Chrome supports opening tabs in the background through specific key combinations. You can simulate these combinations using JavaScript and programmatically open background tabs.
The code below demonstrates simulating a Ctrl click event on a dynamically created element:
function openNewBackgroundTab(){ var a = document.createElement("a"); a.href = "http://www.google.com/"; var evt = document.createEvent("MouseEvents"); // The tenth parameter of initMouseEvent sets the Ctrl key evt.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0, true, false, false, false, 0, null); a.dispatchEvent(evt); }
By invoking this function, you can open a new page in a background tab without causing the annoying flicker.
Note: This approach has been tested only in Chrome.

The following points should be noted when processing dates and time in JavaScript: 1. There are many ways to create Date objects. It is recommended to use ISO format strings to ensure compatibility; 2. Get and set time information can be obtained and set methods, and note that the month starts from 0; 3. Manually formatting dates requires strings, and third-party libraries can also be used; 4. It is recommended to use libraries that support time zones, such as Luxon. Mastering these key points can effectively avoid common mistakes.

Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.

Java and JavaScript are different programming languages. 1.Java is a statically typed and compiled language, suitable for enterprise applications and large systems. 2. JavaScript is a dynamic type and interpreted language, mainly used for web interaction and front-end development.
