问题 The addEventListener DOM method supports a third optional, boolean parameter (useCapture) to indicate whether the function should use event bubbling or event capturing as propagation method. In this article the difference is nicely shown (click on the examples & view code). From other questions on SO and blog posts, I concluded event bubbling was preferred mostly because IE8- didn't support it. Suppose I'm only required to support IE9+, in what situation would event capturing be necessary or

问题 We are trying to repeat the same thing that was done is this plugin: https://github.com/mapsplugin/cordova-plugin-googlemaps/blob/master/README.md (How does this plugin work) but using react-native + mapbox gl(native). The idea is simple: webview and mapview are "siblings", webview is above mapview and part of webview is transparent and mapview is shown under it. We would like any touch events that occur in this transparent area not to be captured by webview and bubble/whatever to mapview so

Event Capturing, Event Bubbling and jQuery.on()

问题 I have an interesting question about event capturing , bubbling and jQuery.on() . I have recently learned more about the difference between event capturing and event bubbling and how the two flow differently in and out of the child-parent elements within the DOM. So to add an event listener with "event capture direction" i would use: element.addEventListener("click", myFunction, true); and to add an event listener with "event bubble direction" i would use: element.addEventListener("click",

Capturing user events (button clicks etc) from another Windows application [closed]

别等时光非礼了梦想. 提交于 2019-11-29 12:27:44
I'm looking to write a .Net Windows application that will capture how a user uses another running application. The simplest form of this would be recording which buttons were clicked or menu items were opened. Capturing the button text or menu text would be enough. I know this can be done by listening for events but was unsure how far this stretched. In Windows are you able to listen to another applications events or are they hidden from other applications? If so, are there any .Net libraries I can use or open source projects to catch these events? Taking this further, turn these into generic

Example for Bubbling and Capturing in React.js

六月ゝ 毕业季﹏ 提交于 2019-11-26 09:36:34
问题 I am looking for an example in handling Bubbling and Capturing in React.js. I found one with JavaScript, but I am having trouble finding the equivalent for React.js. How would I have to create an example for Bubbling and Capturing in React.js? 回答1: Bubbling and capturing are both supported by React in the same way as described by the DOM spec, except for how you go about attaching handlers. Bubbling is as straightforward as with the normal DOM API; simply attach a handler to an eventual
