Question

我的网站上有一个功能，可以在单击电子邮件地址时复制它。它可以在Chrome上完美运行，但文本不会在Safari上被选中。我还能做些什么来使其在Safari上正常工作吗？

在这里摆弄着各自的代码： https://jsfiddle.net/zsoltszilvai/odbxze9j/12/

function myFunction3() {
  var copyText = document.getElementById("myInput3"),
  range = document.getSelection().getRangeAt(0),
  tooltip = document.getElementById("myTooltip3");

  range.selectNode(copyText);
  document.execCommand("Copy");
  tooltip.innerHTML = "Copied";
}

function outFunc3() {
  var tooltip = document.getElementById("myTooltip3");
  tooltip.innerHTML = "Click to copy";
}

        var range = document.createRange();
        range.selectNodeContents(text);
        selection.removeAllRanges();

不同的浏览器可能有不同的内容选择方式，因此我在这里编写了selectText方法，可以在Safari上正常工作。

范围= document.getSelection（）。getRangeAt（0）在Safari上不起作用
