How to use the better-scroll plug-in in the project

This time I will show you how to use the better-scroll plug-in in the project, and what are the precautions for using the better-scroll plug-in. The following is a practical case, let's take a look.

Use of better-scroll

Since infinite scrolling needs to be done at a fixed height, originally CSS overflow-y can also be completed, but Android is not very It's smooth, but still very stiff. It uses the third-party library better-scroll and cooperates with Angular's ng-content. Angular's ng-content is very similar to Vue's slot, and some uncertain content can be projected into it through ng-content.

Install better-scroll

1: npm install better-scroll --save

2: Install types npm install better-scroll @types/ better-scroll --save

3: Introduce

listscroll component writing in angular-cli

According to the official documentation, better-scroll has requirements for the DOM structure. The outermost wrapper layer needs to have a fixed height, and the inner layer of content is supported according to the height of the content.

html part:

<p>
 <ng-content></ng-content>
</p>

ng-content is the content to be projected in

component.ts part

1: import introduces BScroll

2: Initialize in the OnInit hook. Since ngFor has not finished executing during OnInit, a timer is added to delay it.

import { Component, OnInit, Input, ElementRef, ViewChild } from '@angular/core';
declare let BScroll;
@Component({
 selector: 'app-listscroll',
 templateUrl: './listscroll.component.html',
 styleUrls: ['./listscroll.component.css']
})
export class ListscrollComponent implements OnInit {
 @ViewChild('scroll') scrollEl: ElementRef;
 @Input()
 private height: number;
 public scroll;
 constructor() { }
 ngOnInit() {
  // 设置高度
  this.scrollEl.nativeElement.style.height = `${this.height}px`; 
  // 初始化
  setTimeout(() => {
   this.scroll = new BScroll(this.scrollEl.nativeElement, {click: true});
  }, 20);
 }
}

Using the listscroll component in other components
