JS 文本选择监听

document.addEventListener("selectionchange", () => {
  console.log(document.getSelection());
});

document.onselectionchange = () => {
  console.log(document.getSelection());
};
// document.getSelection() 选中文本信息，document.getSelection().toString() 则返回选中文本

const selection = document.getSelection()
const oRange = selection.getRangeAt(0)
const oRect = oRange.getBoundingClientRect()
const text = selection.toString()
