从任何 `html` 元素中选择选定的文本（不仅来自输入）

  • 772

假设我们有一些段落。

<p>Lorem Ipsum is simply dummy text of the printing and typesetting industry.</p>
<p>Lorem Ipsum has been the industry's standard dummy text ever since the 1500s</p>
<p>when an unknown printer took a galley of type and scrambled it to make a</p>

用鼠标，我从其中任何一个中选择了部分文本。所以这就是我如何在此之后或在获取阶段获取所选文本的方法。更好的是，这个文本的容器是相同的。

javascript

    有趣的是，我window.getSelection()只考虑输入。但是用鼠标选择的所有内容都会在其中选择。答案就在我的眼皮底下。

    function getSelectionText(){
  var text = "";
  text = window.getSelection().toString();
  return text;
}
document.onmouseup = document.onkeyup = document.onselectionchange = function() {
  document.getElementById("sel").value = getSelectionText();
};
    <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry.</p>
<p>Lorem Ipsum has been the industry's standard dummy text ever since the 1500s</p>
<p>when an unknown printer took a galley of type and scrambled it to make a</p>
<textarea id="sel" rows="6" cols="50"></textarea>
