Hi all.
I need to know how to restore or roll back to built-in function after overriding like following example.
String.prototype.substr= function()
{ return "";}
Now I want to use the one already built-in.
I shall be very thankful if some one could help me.

Hi All.
Do any body know how to call built in function of object like substr from overridden version. I am trying following example but the function called itself recursively not the function being overridden.
String.prototype.substr= function(str)
{
return str.substr(0,5);
}
I shall be very thankful if some one could give me some hints.

I don't think its possible to revert to the old function unless you save it somewhere.
eg:
eg:
String.prototype._substr = String.prototype.substr;
String.prototype.substr= function()
{
return this._substr(0,5);
