jjb-lc-designable/core/drivers/MouseMoveDriver.js

基于alibaba-designable源码二次封装的表单设计器。

import { EventDriver } from 'jjb-lc-designable/shared';
import { MouseMoveEvent } from '../events';
export class MouseMoveDriver extends EventDriver {
  request = null;
  onMouseMove = e => {
    this.request = requestAnimationFrame(() => {
      cancelAnimationFrame(this.request);
      this.dispatch(new MouseMoveEvent({
        clientX: e.clientX,
        clientY: e.clientY,
        pageX: e.pageX,
        pageY: e.pageY,
        target: e.target,
        view: e.view
      }));
    });
  };
  attach() {
    this.addEventListener('mousemove', this.onMouseMove, {
      mode: 'onlyOne'
    });
  }
  detach() {
    this.removeEventListener('mouseover', this.onMouseMove, {
      mode: 'onlyOne'
    });
  }
}
