How can I match the following pattern?
"anything123.anythingelse"
Alphanum of any length, with exactly 1 "." in the middle, and then alphanum of any length?
Thanks.
That would then be /[a-z0-9]+\\.[a-z0-9]+/i
. The /i
is the case insensitive modifier.
var match = /[a-z0-9]+\.[a-z0-9]+/i.test(string);
alert(match); // true or false.
If you can allow underscores, this can be done shorter: /\\w+\\.\\w+/
. The \\w
is the same as [a-zA-Z0-9_]
.
