trigger() can time out waiting for the element to reach an pageX You can find the related objects in the Supported by objects section below. Or, if you need the element that is located at a specified position, use the elementFromPoint method. Until all chained assertions have passed. To get the position relative to the top-left corner of the screen, use the screenX and screenY properties. 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. 0:00 / 3:55 clientX vs pageX vs screenX vs offsetX Steve Griffith - Prof3ssorSt3v3 87.4K subscribers Subscribe 713 Share Save 22K views 3 years ago JavaScript in the Browser This. 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. I explained the problem, W3C’s vagueness and the use of pageX/Y and clientX/Y in my slightly outdated Evolt article. Sometimes impossible to set the value of some properties like pageX, pageY. These are the six property pairs see also the Event compatibility tables or the W3C DOM Compatibility - Events page. 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 pageX clientX + width of the scrolled-out horizontal part of the document. The two coordinate systems are connected by the formula: pageY clientY + height of the scrolled-out vertical part of the document. Since any arbitraryĮvent can be triggered, Cypress tries not to make any assumptions about how it There’s no standard method to get the document coordinates of an element. 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. This includes any portion of the document not currently visible. trigger() is an "action command" that follows all the rules ofĪctionability. The pageX read-only property of the MouseEvent interface returns the X (horizontal) coordinate (in pixels) at which the mouse was clicked, relative to the left edge of the entire document. 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 differences between clientX and clientY and screenX and screenY: let cX event.clientX let cY event.clientY let sX event.screenX let sY event.screenY Try it Yourself » Browser Support event.clientX is a DOM Level 2 (2001) feature. You can also include arbitrary event properties (e.g. Whether to wait for elements to finish animating before executing the command.

Hope this can be useful for others: function fixTouch (touch) else if (y < (touch.pageY - winPageY) || x < (touch.The distance in pixels from element's left to trigger the event. I've found a way to detect the bugs and calculate the correct values.
#Js screenx versus pagex android#
I have seen this bug in iOS4 and a different bug in Android 4.0. It's a bug in older versions of webkit that occur when the page is scrolled.
