The handler then checks if the element that triggered the event matches your selector (dynamicChild). I created this resource to help you understand event propagation and how it works in JavaScript and React in a clear and comprehensible way. The basic use case is similar and includes methods like stopPropagation and preventDefault (which I will discuss later). How can we fix this? The keypress event is sent to an element when the browser registers To solve this issue, lets utilize Reacts state pattern! There is also technically another phase called the None Phase, where no event phase is occurring. Connect and share knowledge within a single location that is structured and easy to search.

After research I have found three working solutions (I forgot the page links for reference), Now there is a plugin for that: outside events (blog post). If you click on the document, hide a given element, unless you click on that same element. How Event Propagation happens in modern JavaScript and how to use. when value from inner popup is selected, immediately closing the popup). The project is hosted on GitHub, and the annotated source code is available, as well as an online test suite, Users not using a mouse will be able to escape your dialog (and your pop-up menu is arguably a type of dialog) by pressing Tab, and they then won't be able to read the content behind the dialog without subsequently triggering a click event. Several methods you can use to fix issues that may come up for your particular case. We can check that this isn't the case by looking at event.relatedTarget (which tells us what element will have gained focus). This is because focusing the inner element triggers a focusout event before triggering a focusin event again. Upon clicking any element within the document, if the clicked element's id is toggled, or the hidden element is not hidden and the hidden element does not contain the clicked element, toggle the element.

If you use event.stopPropogation() on a click event, no other elements in your page can have a click-anywhere-to-close feature. get a reference to the element and then event.target, and finally != or == both of them then execute code accordingly..
