How Can I Open a New Tab in the Background from JavaScript Without a Flash?

Can I Open a New Tab in the Background While Staying on the Current Tab?

When working with JavaScript, it is possible to open a new page in a different tab while staying focused on the current tab using the following code:

open('http://example.com/');
focus();

However, this approach may cause a momentary flash of the new tab before switching back to the current tab in Chrome. To avoid this issue, a more sophisticated method is required.

Solution: Simulating Key Events

This solution involves simulating a key combination (e.g., Ctrl click) on a dynamically generated element to create a background tab. The following code accomplishes this:

function openNewBackgroundTab(){
    var a = document.createElement("a");
    a.href = "http://www.google.com/";
    var evt = document.createEvent("MouseEvents");
    // Simulate Ctrl key press
    evt.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0, true, false, false, false, 0, null);
    a.dispatchEvent(evt);
}

This method works by creating an element, setting its href attribute to the desired URL, and then dispatching a click event with the "Ctrl" key simulated. This results in a background tab being opened without affecting the focus of the current tab.
