I would like to simulate a whole click not just
document.getElementsByClassName()[0].click();
How do I do that? Search results all seem to be about handling such events, not triggering them.
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();
