![]() ![]() W3C DOM Compatibility - Events page for a description. The other three property pairs are unimportant. You never need to know the mouse position relative to the screen - well, maybe only if you want to place another window at the mouse position. The screenX property returns the x (horizontal) coordinate of a window, relative to the screen. ![]() Unfortunately this information is completely useless: They give the mouse position relative to the entire computer screen of the user. The screenX and screenY properties are the only ones that are completely cross–browser compatible. I explained the problem, W3C’s vagueness and the use of pageX/Y and These are the six property pairs - see also the Although there are no less than six mouse coordinates property pairs, there is no reliable cross–browser way to find the mouse coordinates relative to the document we need. trigger() can time out waiting for assertions you've added to pass.Hi, For more information about this, See:Īs to the mouse position, the situation is horrible. 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 PageX and clientX, these two are easier to confuse, PageX. 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. 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. 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. 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. Most properties of event class instances are read-only. 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. The event point is where the user clicked and the reference point is a point in the upper left. trigger() yields the same subject it was given. pageX, pageY, screenX, screenY, clientX, and clientY returns a number which indicates the number of logical CSS pixels an event point is from the reference point. PageX, etc) will override the position coordinates. Passing in coordinate arguments ( clientX, You can also include arbitrary event properties (e.g. If you need the position of the mouse pointer relative to the top-left corner of the browser window's client area, use the clientX and clientY properties. To get the y-coordinate of the mouse, use the pageY property. Whether to wait for elements to finish animating before executing the command. property (event) Retrieves the x-coordinate of the mouse pointer relative to the top-left corner of the document. 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 screenX and screenY properties are the only ones that are completely crossbrowser compatible. 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. ![]()
