Search string 2

[dle46163]

I can do this using PHP but not sure on syntax for javascript.. I have a variable: yo = test.jpg. I need to get all the characters after the period. In other words, I just need to get the file extension (excluding the period). Any thoughs would be great!

You could use the split() method to get an array.

var yo = "test.jpg";
var fileparts = yo.split(".");
var ext = "." + fileparts[1];

or you could use substring/indexof

var yo = "test.jpg";
var ext = yo.substring(yo.indexOf("."), yo.length);

Of course, this would only work when there is only one "." in the file name.

A slight variation on ninjadeathmonkey's code to handle the possibility of more than one period in the name:

var yo = "test.jpg";
var fileparts = yo.split(".");
var ext = "." + fileparts[fileparts.length - 1];

and

var yo = "test.jpg";
var ext = yo.substring(yo.lastIndexOf("."));

Ah, very good! I forgot about lastIndexOf().
