在Angular中做到这一点并保持代码简单的最好方法就是使用这个项目。

https://www.npmjs.com/package/ngx-clipboard

    <fa-icon icon="copy" ngbTooltip="Copy to Clipboard" aria-hidden="true" 
    ngxClipboard [cbContent]="target value here" 
    (cbOnSuccess)="copied($event)"></fa-icon>

我知道这已经高度投票在这里到现在为止，但我宁愿去一个自定义指令的方法，并依赖于ClipboardEvent的@jockeisorby建议，同时也确保侦听器被正确删除(相同的功能需要为添加和删除事件侦听器提供)

stackblitz试样

import { Directive, Input, Output, EventEmitter, HostListener } from "@angular/core";

@Directive({ selector: '[copy-clipboard]' })
export class CopyClipboardDirective {

  @Input("copy-clipboard")
  public payload: string;

  @Output("copied")
  public copied: EventEmitter<string> = new EventEmitter<string>();

  @HostListener("click", ["$event"])
  public onClick(event: MouseEvent): void {

    event.preventDefault();
    if (!this.payload)
      return;

    let listener = (e: ClipboardEvent) => {
      let clipboard = e.clipboardData || window["clipboardData"];
      clipboard.setData("text", this.payload.toString());
      e.preventDefault();

      this.copied.emit(this.payload);
    };

    document.addEventListener("copy", listener, false)
    document.execCommand("copy");
    document.removeEventListener("copy", listener, false);
  }
}

然后像这样使用它

<a role="button" [copy-clipboard]="'some stuff'" (copied)="notify($event)">
  <i class="fa fa-clipboard"></i>
  Copy
</a>

public notify(payload: string) {
   // Might want to notify the user that something has been pushed to the clipboard
   console.info(`'${payload}' has been copied to clipboard`);
}

注意:IE需要窗口["clipboardData"]，因为IE不理解e.clipboardData

copyCurl(val: string){
    navigator.clipboard.writeText(val).then( () => {
      this.toastr.success('Text copied to clipboard');
    }).catch( () => {
      this.toastr.error('Failed to copy to clipboard');
    });
}

从Angular Material v9开始，它现在有了一个剪贴板CDK

剪贴板|角材料

它可以简单地使用

<button [cdkCopyToClipboard]="This goes to Clipboard">Copy this</button>

在Angular中做到这一点并保持代码简单的最好方法就是使用这个项目。

https://www.npmjs.com/package/ngx-clipboard

    <fa-icon icon="copy" ngbTooltip="Copy to Clipboard" aria-hidden="true" 
    ngxClipboard [cbContent]="target value here" 
    (cbOnSuccess)="copied($event)"></fa-icon>

很简单，兄弟

在.html文件

<button (click)="copyMessage('This goes to Clipboard')" value="click to copy" >Copy this</button>

在.ts文件

copyMessage(text: string) {
  navigator.clipboard.writeText(text).then().catch(e => console.log(e));
}
