Xiaoqiang’s HTML5 mobile development road (52) - touch interaction in jquerymobile

黄舟Original: 2017-02-15 14:00:161504browse

When using mobile devices for touch operations, the most commonly used ones are tapping, pressing and holding the screen, or gesture operations. jQuery Mobile can respond to the user's specific touch behavior through bound touch events.

1. Tap and hold

to enter the code directly (everything is in the code, take a closer look!)

2. Swipe

Swipe refers to writing with your finger or hand When the pen slides quickly left or right on the screen, the swipeleft event or swiperight event will be triggered.

A trick is used in the above code. If you need to change the switching effect during the interface switching process, you must use a hyperlink to implement it. Set the display attribute of the link If it is none, call the click() method in the listening function to perform interface switching, and then add data-transition to the link to set the switching effect.

3. Virtual mouse event

##EventMeaningvmouseoverTouch or slide over the DOM containervmoseoutTouch Or slide away vmousedown touch or press vmoseupTouch off or mouse button ReleasevclickThe touch ends or the mouse button is releasedThe vclick event is usually in vmouseup Triggered 300ms after the eventvmousecancelTriggered when the mousecancel event is initiated in the touch event...... ..................
