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));
}

以下是@Sangram的回答(以及@Jonathan的评论)的解决方案1:

(支持“不要在angular中使用普通文档”和“如果你没有必要，不要从代码中添加HTML元素……”)

// TS @ViewChild('textarea') textarea: ElementRef; constructor(@Inject(DOCUMENT) private document: Document) {} public copyToClipboard(text): void { console.log(`> copyToClipboard(): copied "${text}"`); this.textarea.nativeElement.value = text; this.textarea.nativeElement.focus(); this.textarea.nativeElement.select(); this.document.execCommand('copy'); } /* CSS */ .textarea-for-clipboard-copy { left: -10000; opacity: 0; position: fixed; top: -10000; } <!-- HTML --> <textarea class="textarea-for-clipboard-copy" #textarea></textarea>

用纯Angular和ViewChild为自己找到了最简单的解决方案。

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

@Component({
  selector: 'cbtest',
  template: `
    <input type="text" #inp/>
    <input type="button" (click)="copy ()" value="copy now"/>`
})

export class CbTestComponent
{
  @ViewChild ("inp") inp : any;

  copy ()
  {
    // this.inp.nativeElement.value = "blabla";  // you can set a value manually too

    this.inp.nativeElement.select ();   // select
    document.execCommand ("copy");      // copy
    this.inp.nativeElement.blur ();     // unselect
  }
}

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

// for copy the text
import { Clipboard } from "@angular/cdk/clipboard"; // first import this in .ts
 constructor(
    public clipboard: Clipboard
  ) { }   
 <button class="btn btn-success btn-block"(click) = "onCopy('some text')" > Copy< /button>

 onCopy(value) {
     this.clipboard.copy(value);
    }


 // for paste the copied text on button click :here is code
    
    <button class="btn btn-success btn-block"(click) = "onpaste()" > Paste < /button>
    
    onpaste() {
      navigator['clipboard'].readText().then(clipText => {
        console.log(clipText);
      });
    }

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
