I have a string in javascript
var Foo = "Bar";
I have a function that does a manipulation on this string. to add this function to the string I did this
String.prototype.func = function(){
// code
}
But this function will work for every string. I want this function to be called only from my variable Foo
So apply it only to the string in the variable Foo.
You'll need to make it a String object rather than a primitive though.
var foo = new String("Bar");
foo.func = function () { ... };
var foo = "Bar"
If you want it to work only on your variable Foo then simply do the following:
var Foo = new String("Bar");
Foo.func = function(){
//code
};
You don't need to add the function to the prototype of String.
TypeError: undefined is not a function
