Copy Code code as follows:

String.prototype.trim=function () {
var _argument = Arguments[0] | | " ";
var _re= new RegExp ("(^" +_argument+ "*) | (" +_argument+ "*$", "G"); Case sensitive
Return This.replace (_re, "");
}
String.prototype.ltrim=function () {
var _argument = Arguments[0] | | " ";
var _re= new RegExp ("(^" +_argument+ "*)", "G");
Return This.replace (_re, "");
}
String.prototype.rtrim=function () {
var _argument = Arguments[0] | | " ";
var _re= new RegExp ("(" +_argument+ "*$)", "G");
Return This.replace (_re, "");
}



String.Trim (",") means delete the "," of the left and right sides of the string, and if trim has no parameters, the default is to delete the spaces at both ends.
More powerful! than the old trim.
