cut out part of a string

Question

Say, I have a string

"hello is it me you're looking for" 

I want to cut part of this string out and return the new string, something like

s = string.cut(0,3); 

s would now be equal to:

"lo is it me you're looking for" 

EDIT: It may not be from 0 to 3. It could be from 5 to 7.

s = string.cut(5,7); 

would return

"hellos it me you're looking for" 

Answer 1

You're almost there. What you want is:

http://www.w3schools.com/jsref/jsref_substr.asp

So, in your example:

Var string = "hello is it me you're looking for"; s = string.substr(3); 

As only providing a start (the first arg) takes from that index to the end of the string.

Update, how about something like:

function cut(str, cutStart, cutEnd){   return str.substr(0,cutStart) + str.substr(cutEnd+1); }
