Simulating a mousedown, click, mouseup sequence in Tampermonkey?

by

Send mouse events. Like so:

//--- Get the first link that has "stackoverflow" in its URL.
var targetNode = document.querySelector ("a[href*='stackoverflow']");
if (targetNode) {
    //--- Simulate a natural mouse-click sequence.
    triggerMouseEvent (targetNode, "mouseover");
    triggerMouseEvent (targetNode, "mousedown");
    triggerMouseEvent (targetNode, "mouseup");
    triggerMouseEvent (targetNode, "click");
}
else
    console.log ("*** Target node not found!");

function triggerMouseEvent (node, eventType) {
    var clickEvent = document.createEvent ('MouseEvents');
    clickEvent.initEvent (eventType, true, true);
    node.dispatchEvent (clickEvent);
}

That works if the web page is statically loaded. If the web page is AJAX-driven, use a technique as in:

Beware:
The question code has an error. You need to pass a class name to that function. Like so:

document.getElementsByClassName ("SomeClassName")[0].click();
