Question

How can I cut text from the end of a variable up until a specific character?

Like this:

a_a_a

And I want the last “A” and split the text at the last “_”:

a_a_ | a

Then I want to get 2 strings witch would be like this:

string A = a_a_
string B = a

Answer 1

You can use lastIndexOf to get the last occurance of the character to be searched and then substr to get the string from that index

var str = "a_a_a";
var startIndex = str.lastIndexOf("_"); //Here we are getting the last index of _ char
var result = str.substr(startIndex); //this will output `_a`
var result = str.substr(startIndex+1); //as we need only `a` we are using `startIndex + 1`
