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

I had no luck with the match approach, but this worked:

If you have the string, "This is my string." and wanted to see if it ends with a period, do this:

var myString = "This is my string.";
var stringCheck = ".";
var foundIt = (myString.lastIndexOf(stringCheck) === myString.length - stringCheck.length) > 0;
alert(foundIt);

You can change the variable stringCheck to be any string to check for. Better still would be to throw this in your own function like this:

function DoesStringEndWith(myString, stringCheck)
{
    var foundIt = (myString.lastIndexOf(stringCheck) === myString.length - stringCheck.length) > 0;
    return foundIt;
}
