javascript - 保持工具提示元素处于打开状态，直到时间工具提示悬停

Question

我有一个框，一旦我们将鼠标悬停在框上，就会出现一个工具提示，当我进入工具提示内部时，工具提示保持打开状态。

对于左侧的方框，工具提示将向其右侧打开。

对于右侧的方框，工具提示将向其左侧打开。

此方案适用于左侧框，但不适用于右侧框。

else if (e.type === 'mouseleave' && e.clientX < x.right) {
 this.modelStyle = {
   display: 'none'
  };
 }

为了处理右侧框的工具提示悬停功能，应该对鼠标离开功能进行哪些更改，以处理与左侧框工具提示相同的行为。

添加超时，然后如果用户打算输入框，它将打开

import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent {
  active = null;
  modelStyle: any = {
    display: 'none'
  };
  modelClickedStyle: any = {
    display: 'none'
  };
  modalStyleClikedFlag;

  addClickEvent(e) {
    let x = e.currentTarget.getBoundingClientRect();
    if (e.type === 'click') {
      this.modalStyleClikedFlag = true;
      this.modelClickedStyle = {
        top: 0 + 'px',
        left: 0 + 'px',
        height: 900 + 'px',
        width: 90 + '%',
        display: 'block'
      };
    }
    else if (e.type === 'mouseenter') {
      this.modalStyleClikedFlag = false;
      if (((window.innerWidth || document.documentElement.clientWidth) - x.right) > 200) {
        this.modelStyle = {
          top: 0 + 'px',
          left: x.right + 'px',
          height: screen.height + 'px',
          width: 65 + '%',
          display: 'flex'
        };
      } else {
        this.modelStyle = {
          top: 0 + 'px',
          right: ((window.innerWidth || document.documentElement.clientWidth) - x.left) - 200 + 'px',
          height: screen.height + 'px',
          width: 65 + '%',
          display: 'flex'
        };

      }
    }
    else if (e.type === 'mouseleave' && e.clientX < x.right) {
      if (this.active) {
        clearTimeout(this.active);
      }
      this.active = setTimeout(() => {
        this.modelStyle = {
          display: 'none'
        };
      }, 1000)
    }
  }

  onPopEvent(e) {
    if (e.type === 'mouseenter') {
      if (this.active) {
        clearTimeout(this.active);
      }
    } else if (e.type === 'mouseleave') {
      this.modelStyle = {
        display: 'none'
      };
    }
  }

}
