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)
