Vue中div contenteditable 的光标定位方法

function keepLastIndex(obj) {
  console.log(obj)
  console.log(window.getSelection)
  console.log(document.selection)
  if (window.getSelection) { //ie11 10 9 ff safari
   obj.focus(); //解决ff不获取焦点无法定位问题
   var range = window.getSelection(); //创建range
   range.selectAllChildren(obj); //range 选择obj下所有子内容
   range.collapseToEnd(); //光标移至最后
  } else if (document.selection) { //ie10 9 8 7 6 5
   var range = document.selection.createRange(); //创建选择对象
   //var range = document.body.createTextRange();
   range.moveToElementText(obj); //range定位到obj
   range.collapse(false); //光标移至最后
   range.select();
  }
 }

setTimeout(()=>{
 keepLastIndex(e.target)
},5)
