I have a page which has a keydown
event listener, to listen for the Escape key, to navigate back. I also have a simple modal class, which also listens for the Escape key to close it. The main page listener checks if a modal is open, and if so, returns without doing anything.
window.addEventListener("keydown", function (ev) {
if (modal_is_open) { return; }
ev = ev || window.event;
if (ev.key == "Escape") { history.go(-1); }
});
modal_div.addEventListener("keydown",function (ev) {
ev = ev || window.event;
ev.stopPropagation();
ev.preventDefault();
ev.cancelBubble = true;
if (ev.key == "Escape") { close_the_modal(); }
return false;
});
My problem is, if a modal is open, the Escape key closes it, but still bubbles up to the main page handler and navigates back. How can I stop this?
I finally found the solution, replace stopPropagation
with stopImmediatePropagation
, and the window keydown handler no longer fires if the modal is open.
