jjb-lc-designable/core/models/Hover.js

基于alibaba-designable源码二次封装的表单设计器。

import { observable, define, action } from 'jjb-lc-formily/reactive';
import { HoverNodeEvent } from '../events';
export class Hover {
  node = null;
  constructor(props) {
    this.operation = props?.operation;
    this.makeObservable();
  }
  setHover(node) {
    if (node) {
      this.node = node;
    } else {
      this.node = null;
    }
    this.trigger();
  }
  clear() {
    this.node = null;
  }
  trigger() {
    if (this.operation) {
      return this.operation.dispatch(new HoverNodeEvent({
        target: this.operation.tree,
        source: this.node
      }));
    }
  }
  makeObservable() {
    define(this, {
      node: observable.ref,
      setHover: action,
      clear: action
    });
  }
}
