如何将剪贴板中的数据粘贴到多个输入字段？

Question

如何使用多个输入执行复制到剪贴板？我有这个代码

HTML 代码

<input type="text" value="Hello" id="myInput1">
<input type="text" value="World" id="myInput2">

<button onclick="myFunction()">Copy text</button>

脚本代码

<script>
function myFunction() {
  var copyText1 = document.getElementById("myInput1");
  var copyText2 = document.getElementById("myInput1");
  copyText1.select();
  copyText1.setSelectionRange(0, 99999)
  document.execCommand("copy");
  alert("Copied the text: " + copyText.value);
}
</script>

Answer 1

您可以添加第三个输入字段（或 textarea，如果您还想添加换行符）并简单地隐藏它。并且，在执行文本选择和复制命令之前，取消隐藏文本区域，然后再次隐藏它。

function myFunction() {
    var copyText1 = document.getElementById("myInput1");
    var copyText2 = document.getElementById("myInput2");
    var hiddenInput = document.getElementById("hiddenInput");
    hiddenInput.value = "Description1: " + copyText1.value + "\nDescription2: " + copyText2.value;
    hiddenInput.style.display = "";
    hiddenInput.select();
    hiddenInput.setSelectionRange(0, 99999);
    document.execCommand("copy");
    hiddenInput.style.display = "none";
    alert("Copied the text:\n" + hiddenInput.value);
}

<input type="text" value="Hello" id="myInput1">
<input type="text" value="World" id="myInput2">
<textarea id="hiddenInput" style="display:none;"></textarea>
    
<button onclick="myFunction()">Copy text</button>

btCopy.onclick=_=>
  {
  // step 1: collect the input values (a method like so many others)
  let inputs = {}
  Array.from(new FormData(myForm),entry=>{inputs[ entry[0] ] = entry[1]})
  let All_inputs = JSON.stringify(inputs)

  // step 2 : write All_inputs into the clipboard
  navigator.clipboard.writeText(All_inputs)

  // as in your wishes...
  alert('Copied the text: ' + All_inputs)
  }

<form id="myForm">
  <input type="text" name="Description1" value="Hello">
  <input type="text" name="Description2" value="world">
</form>

<button id="btCopy">copy</button>
