![]() ![]() Where zoom = documentElement.clientWidth / window.innerWidth Many browsers make it the same as page or client Chrome makes it relative to the screen BUT IN CSS PIXELS, and for vertical measurements you have to subtract the toolbars as well. ScreenX/Y = clientX/Y * devicePixelRatio * zoom, screen Very old defintion: relative to the screen, in device pixels. I calculate the expected positions as follows: page Relative to the document client Old definition: relative to the visual viewportĬlientX/Y = pageX/Y - window.pageX/YOffset New definition: relative to the layout viewportĬlientX/Y = pageX/Y - ().left/top What changed here in Chromium 40/Edge is not so much the definition of clientX/Y, but of getBoundingClientRect(), probablyīecause the layout viewport as a separate scrollable layer was introduced. This test interprets the coordinates as page coordinates (i.e. trigger() can time out waiting for assertions you've added to pass.Click on the page to set the three test layers. trigger() can time out waiting for the element to reach an ![]() Until all chained assertions have passed. trigger() will automatically wait for the element to reach an trigger() requires being chained off a command that yields DOM element(s). trigger() is an excellent stop-gap if theĬommand / event you're looking for hasn't been implemented yet. The browser to actually "do" anything for these events. The screenX property retrieves the position of the mouse in physical pixel size in Firefox, Opera, Google Chrome, Safari and in Internet Explorer earlier than version 8, while from version 8, it returns the position in logical pixel size. That means that your event listener callbacks will be invoked, but don't expect trigger() will only fire the corresponding event and do nothing else. Note: In a multiscreen environment, screens aligned horizontally will be treated as a single device, and so the range of the screenX value will increase to the combined width of the screens. In other words, what's the difference between:īoth types commands will first verify element actionability, but only the "true"Īction commands will implement all of the default actions of the browser, andĪdditionally perform low level actions to fulfill what's defined in the spec. The screenX read-only property of the MouseEvent interface provides the horizontal coordinate (offset) of the mouse pointer in global (screen) coordinates. Differences What's the difference between triggering and event and calling the corresponding cypress command? This can be problematic in when testing some situations. Sometimes impossible to set the value of some properties like pageX, pageY. The Touch. Most properties of event class instances are read-only. The Touch.screenX property is the horizontal (x) coordinate of a touch point relative to the screen in CSS pixels. Why should I manually set the event type? ![]() (which may be in a 3rd party library) of the event handler(s) receiving theĮvent and provide the necessary properties. This means you'll need to know the implementation details Since any arbitraryĮvent can be triggered, Cypress tries not to make any assumptions about how it Events What event should I fire? Ĭy.trigger() is meant to be a low-level utility that makes triggering eventsĮasier than manually constructing and dispatching them. trigger() is an "action command" that follows all the rules ofĪctionability. Notes Actionability The element must first reach actionability Happening (it must be visible and not disabled). The DOM element must be in an "interactable" state prior to the triggered event trigger().Įxamples Mouse Events Trigger a mouseover on the button To chain further commands that rely on the subject after. trigger() yields the same subject it was given. ![]() PageX, etc) will override the position coordinates. Passing in coordinate arguments ( clientX, The Touch.screenY property is the vertical coordinate of a touch point relative to the screen in CSS pixels. You can also include arbitrary event properties (e.g. The Touch.screenX property is the horizontal (x) coordinate of a touch point relative to the screen in CSS pixels. Whether to wait for elements to finish animating before executing the command. Viewport position to where an element should be scrolled before executing the command MouseEvent, KeyboardEvent)įorces the action, disables waiting for actionability The constructor for creating the event object (e.g. The distance in pixels an element must exceed over time to be considered animating. Pass in an options object to change the default behavior of. The distance in pixels from element's top to trigger the event. The distance in pixels from element's left to trigger the event. ![]()
