How to Get The Last Character of a String Using jQuery?

You can use the .slice() method, its cross browser compatible.

var id = "example1";
id.slice(-1); //Outputs: 1

Getting the last character is easy, as you can treat strings as an array:

var id = "example2";
var lastChar = id[id.length-1]; //Outputs: 2

To get a section of a string, you can use the substr function

var id = "example3";
id.substr(id.length-1); //Outputs: 3
