JavaScript or jQuery string ends with utility function

Question

what is the easiest way to figure out if a string ends with a certain value?

Answer 1

you could use Regexps, like this:

str.match(/value$/) 

which would return true if the string has 'value' at the end of it ($).

Answer 2

Stolen from prototypejs:

String.prototype.endsWith = function(pattern) {     var d = this.length - pattern.length;     return d >= 0 && this.lastIndexOf(pattern) === d; };  'slaughter'.endsWith('laughter'); // -> true
