采用JavaScript得到当前用户选中文本，有一定的浏览器局限性！
IE：document.selection FireFox：window.getSelection() 或有其他浏览器
?
<html>
<head>
<title>Readme</title>
?<script type="text/javascript">
???function getSelectedText(){
????var selectedText ="";
????if(window.getSelection) {??
?????????? selectedText = window.getSelection().getRangeAt(0);??
