[thelist] Use of "replace" method in JavaScript

[Simon Dell]

Syed,

The replace function is a method of the String object.

      string.replace(regExpr,newString)

where regExpr is either a quoted string ("a string") or a regular 
expression (/pattern/) and newString is a string.

The replace method searches the string for a piece of text which matches 
regExpr (either a direct match for the string or a pattern match when using 
a regular expression). For more information on regular expressions, try 
this tutorial:

So
"John went to the historical city of Lahore for spending 
vacation.".replace("historical city of Lahore","beautiful city of Swat")
will do what you want, but it's not very flexible.

I hope that's helpful,
Simon
