参考代码:

1

<script type="text/javascript">
var fendata="9,45|4,12|9,21|";
var pid='9';
var rstr =new RegExp(pid+",\\d{1,2}\\|","g");
alert(rstr);
alert(fendata.replace(rstr,
''));
alert(fendata);
</script>

  

2

/*
*unicode编码和字符相互转化
*/
"".charCodeAt() == 35201; //true,35201为10进制值
String.fromCharCode(35201) == "要"; //true,35201为10进制值
"\u89" + "81" == ""; //false,值为"u8981",是由于"\u"会转义成"u"

//从unicode编码到字符的方法
eval("(\"\u89" + "81\")") == ""; //true,8981为16进制值

  

结论:

   var ins = String.fromCharCode(160);
ins
= new RegExp(ins, "g");
s
= s.replace(ins, "");
