Get value of a string after last slash in JavaScript

Question

I am already trying for over an hour and cant figure out the right way to do it  although it is probably pretty easy   I have something like this   foo bar test html  I would like to use jQuery to extract everything after the last    In the example above the output would be test html   I guess it can be done using substr and indexOf    but I cant find a working solution

At least three ways   A regular expression   var result            exec  foo bar test html   0        which says  grab the series of characters not containing a slash          at the end of the string      Then it grabs the matched characters from the returned match object by indexing into it   0    in a match object  the first entry is the whole matched string  No need for capture groups   Live example  Using lastIndexOf and substring   var str    foo bar test html   var n   str lastIndexOf       var result   str substring n   1     lastIndexOf does what it sounds like it does  It finds the index of the last occurrence of a character  well  string  in a string  returning -1 if not found  Nine times out of ten you probably want to check that return value  if  n     -1    but in the above since we re adding 1 to it and calling substring  we d end up doing str substring 0  which just returns the string   Using Array split  Sudhir and Tom Walters have this covered here and here  but just for completeness   var parts    foo bar test html  split       var result   parts parts length - 1      Or parts pop      split splits up a string using the given delimiter  returning an array   The lastIndexOf   substring solution is probably the most efficient  although one always has to be careful saying anything about JavaScript and performance  since the engines vary so radically from each other   but unless you re doing this thousands of times in a loop  it doesn t matter and I d strive for clarity of code
