javascript - 点击复制没有复制按钮

Question

function myFunction() {
  var copyText = document.getElementById("myInput");
  copyText.select();
  document.execCommand("Copy");

  var tooltip = document.getElementById("myTooltip");
  tooltip.innerHTML = "Copied: " + copyText.value;
}

function outFunc() {
  var tooltip = document.getElementById("myTooltip");
  tooltip.innerHTML = "Copy to clipboard";
}

.tooltip {
    position: relative;
    display: inline-block;
}

.tooltip .tooltiptext {
    visibility: hidden;
    width: 140px;
    background-color: #555;
    color: #fff;
    text-align: center;
    border-radius: 6px;
    padding: 5px;
    position: absolute;
    z-index: 1;
    bottom: 150%;
    left: 50%;
    margin-left: -75px;
    opacity: 0;
    transition: opacity 0.3s;
}

.tooltip .tooltiptext::after {
    content: "";
    position: absolute;
    top: 100%;
    left: 50%;
    margin-left: -5px;
    border-width: 5px;
    border-style: solid;
    border-color: #555 transparent transparent transparent;
}

.tooltip:hover .tooltiptext {
    visibility: visible;
    opacity: 1;
}

<input type="text" value="Hello World" id="myInput">

<div class="tooltip">
<button onclick="myFunction()" onmouseout="outFunc()">
  <span class="tooltiptext" id="myTooltip">Copy to clipboard</span>
  Copy text
  </button>
</div>

这是一个带有复制按钮的例子。我想删除复制按钮，单击文本并在没有复制按钮的情况下进行复制，更清楚我想添加表情符号，因此单击表情符号并在没有复制按钮的情况下进行复制。示例:<input type="text" value="😎" id="myInput">我该怎么做？谢谢

只需将点击事件绑定(bind)到您要复制的位置的特定选择器。这里我绑定(bind)了点击事件输入。

function myFunction() {
  var copyText = document.getElementById("myInput");
  copyText.select();
  document.execCommand("Copy");
}

<input type="text" value="Hello World" id="myInput" onclick="myFunction()">
