How to use the better-scroll plug-in in Angular_AngularJS
This article mainly introduces the method of using the better-scroll plug-in in Angular. Now I will share it with you and give you a reference.
The use of better-scroll
Since infinite scrolling needs to be done at a fixed height, the overflow-y of CSS can also be completed, but what happens? Android is not very smooth and is still very stiff, so 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 class="scroll" #scroll> <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 OnInit, ngFor has not yet completed execution, so a timer is added to delay .
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);
}
}Use the listscroll component in other components
<app-listscroll [height]="height">
<ul>
<li class="item" *ngFor="let item of list; let num = index;">第{{num}}个</li>
</ul>
</app-listscroll>The above is I compiled it for everyone, I hope it will be helpful to everyone in the future.
