參考代碼:

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編碼和字元相互轉化
*/
"要".charCodeAt() == 35201; //true,35201為10進位值
String.fromCharCode(35201) == "要"; //true,35201為10進位值
"\u89" + "81" == "要"; //false,值為"u8981",是由於"\u"會轉義成"u"

//從unicode編碼到字元的方法
eval("(\"\u89" + "81\")") == "要"; //true,8981為16進位值

  

結論:

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