javascript - 自动重定向到扫描的链接

Question

我在我的应用程序中使用 ionic-Angular 应用程序中的 ngx-zxing 模块实现了 qr 扫描仪。

扫描后我想将用户重定向到扫描链接直接重定向的页面，而无需用户手动干预。

code.html

<!-- code for qr scanner alreday implemented, the result is present in the below code -->

<div>
<a href="{{qrResult}}" #link></a>
</div>

code.ts

//all imports and components are written.I am directly implementing the function definition in in which I have to redirect to the link.


handleQrCodeResult(result: string) {
    console.log("Result", result);
    this.qrResult = result;
    this.clickLink();

  }

clickLink(){
  let el = (<HTMLImageElement>document.getElementById('link'))
    console.log('el', el); // this is returning null.
el.click();
 }

Answer 1

Have a look, the following code doesn't require human interaction

handleQrCodeResult(result: string) {
  console.log("Result", result);
  this.qrResult = result;

  // This line will redirect to the link you want
  window.location.href = "Insert link here";    // Maybe: document.getElementById('link')
}

Explanation

1. window.location.href = "URL";如果将 url 分配给此变量，浏览器将重定向到同一页面中的 url，不会打开新选项卡
2. window.open("URL", "_blank");使用它在新选项卡中打开网址
