Summary of basic events on mobile terminals and summary of basic events on mobile terminals
1. touch event
Touchstart is triggered when the finger is placed on the screen.
The touchmove finger moves on the screen and is triggered continuously.
Touchend finger exit screen trigger
Touchcancel is triggered when the system stops the tracking. This event is temporarily unavailable
Note:
1. You can only add events on the mobile terminal through the listening function, but not on.
2. Do not use the mou

HSDPA business program, will launch a 3.6mb/s HSDPA terminal.
(2) The goal of HSUPA is to focus on the increase of uplink rate, theoretically the peak transmission rate can reach 5.76mb/s. Its standardization work is still in the process of development and is expected to be completed by June 2005.

The CDMA2000 wireless interface has two evolutionary routes on the standard Evolution route: CDMA2000 1X ev-do and CDMA2
Turn from: The distribution and consumption mechanism of Touch events under Android programmingTouch event-related methods include: Dispatchtouchevent (motionevent ev), onintercepttouchevent (motionevent ev), Ontouchevent (motionevent EV); The controls that respond to these methods include: ViewGroup and its subclasses, Activity. The corresponding relationship be

The event object must be used in the event calling function of an object.
Event function: a function called by an event. Whether a function is an event function is determined when it is called instead of being defined.

IE/Chrome: event is a built-in Global Object (can be used directly)

Standard: The event object is passed in through the first parameter of the event function.

Methods related to Touch events in Android include dispatchTouchEvent (MotionEvent ev), onInterceptTouchEvent (MotionEvent ev), and onTouchEvent (MotionEvent ev). controls that can respond to these methods include: viewGroup, View, and Activity. Most of the controls that inherit ViewGroup are container controls, such as LinearLayout, while most of the controls th

Don't think it's a bunch of nonsense, we can get a lot of information from it, summed up as follows:
Drag = mouse down + mouse move + mouse bounce on
This completes a drag-and-drop task, well, this is the principle of drag and drop, want to achieve drag, natural implementation of the above 3 actions, you can simulate drag-and-drop effect, good, corresponding JavaScript in the syntax is required t
Because the ie event is global and firefox event is local, it is not easy to use. At this time, we need to assemble common event operations by ourselves and encapsulate them into classes for reuse.
Copy codeThe Code is as follows :/**
Class Event
Usage:
Event. getEvent (); get the event of ie and firefox
Event. getTarget (); get srcElement of ie or target of firefox
Event. isIe (); whether it is ie
Event. clientX (); get the x coordinates of ie and fox mouse
Event. clientY (); get y coordinates

However, this query can only fetch two
