pointerType 只读特性在 PointerEvent interface indicates the device type (mouse, pen, or touch) that caused a given pointer event.

句法

var pType = pointerEvent.pointerType;

返回值

pType

The event's pointer type. The supported values are the following strings:

"mouse"
"pen"
"touch"

If the device type cannot be detected by the browser, the value can be an empty string ( "" ). If the browser supports pointer device types other than those listed above, the value should be vendor-prefixed to avoid conflicting names for different types of devices.

范例

This example illustrates using the value of the pointerType property to call the appropriate pointer type processing function.

targetElement.addEventListener('pointerdown', function(event) {
  // Call the appropriate pointer type handler
  switch (event.pointerType) {
    case 'mouse':
      process_pointer_mouse(event);
      break;
    case 'pen':
      process_pointer_pen(event);
      break;
    case 'touch':
      process_pointer_touch(event);
      break;
    默认：
      console.log(`pointerType ${event.pointerType} is not suported`);
  }
}, false);
