Which is part of the string does substring ( ) return?
The substring() method returns the part of the string between the start and end indexes, or to the end of the string.
The substring () and slice () methods are almost identical, but there are a couple of subtle differences between the two, especially in the way negative arguments are dealt with. The substring () method swaps its two arguments if indexStart is greater than indexEnd, meaning that a string is still returned.
The index of the first character to include in the returned substring. The index of the first character to exclude from the returned substring. A new string containing the specified part of the given string.
How to fire activetabchanged event of Ajax : tabcontainer?
I have an ajax:TabContainer on my web form and have 2 TabPanel ‘s in TabContainer . I need to call server side methods when the user clicks on the second TabPanel.

The slice method also expects the same two parameters: If we don’t set an ending index, then we get a substring starting from the given index number until the end of the original string: If we set both the startIndex and the endIndex, then we will get the characters between the given index numbers of the original string:
What happens if indexend is greater than substring ( )?
If indexEnd is omitted, substring () extracts characters to the end of the string. If indexStart is equal to indexEnd , substring () returns an empty string. If indexStart is greater than indexEnd, then the effect of substring () is as if the two arguments were swapped; See example below.
