Below we will use this attribute to add three methods to the String object: Trim, LTrim, RTrim (the function is the same as the function of the same name in VbScript)
String.prototype.Trim = function()
{
return this.replace(/(^s*)|(s*$)/g , "");
}
String.prototype.LTrim = function()
{
return this.replace(/(^s*)/g, "");
}
String.prototype.Rtrim = function()
{
return this.replace(/(s*$)/g, "");
}
How about, It’s simple, let’s look at an example of use:
