Angular 5-复制到剪贴板 [英] Angular 5 - Copy to clipboard

问题描述

我正在尝试实现一个图标，单击该图标会将变量保存到用户的剪贴板.我目前已经尝试了几个库，但没有一个库能够这样做.

I am trying to implement an icon that when clicked will save a variable to the user's clipboard. I have currently tried several libraries and none of them have been able to do so.

如何在Angular 5中将变量正确复制到用户剪贴板?

推荐答案

解决方案1:复制任何文本

HTML

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

.ts文件

copyMessage(val: string){
    const selBox = document.createElement('textarea');
    selBox.style.position = 'fixed';
    selBox.style.left = '0';
    selBox.style.top = '0';
    selBox.style.opacity = '0';
    selBox.value = val;
    document.body.appendChild(selBox);
    selBox.focus();
    selBox.select();
    document.execCommand('copy');
    document.body.removeChild(selBox);
  }

Solution 2: Copy from a TextBox

HTML

 <input type="text" value="User input Text to copy" #userinput>
      <button (click)="copyInputMessage(userinput)" value="click to copy" >Copy from Textbox</button>

.ts文件

    /* To copy Text from Textbox */
  copyInputMessage(inputElement){
    inputElement.select();
    document.execCommand('copy');
    inputElement.setSelectionRange(0, 0);
  }

解决方案3:导入第三方指令 ngx-clipboard

<button class="btn btn-default" type="button" ngxClipboard [cbContent]="Text to be copied">copy</button>
