为javascript加上trim方法

<script language="javascript">

String.prototype.trim= function() 
{ 
 return this.replace(/(^\s*)|(\s*$)/g, ""); 
} 

var strCode = "        daaaddk";

alert(strCode.trim());

</script>

 str=str.replace(/(^[^u4e00-u9fa5])|([^u4e00-u9fa5]$)/g,"");  
 return str;
}

连全角空格也trim掉。 不过汉字也会trim.。 不知全角空格的码值，若获知请告诉我。
