hyperlink - Jquery to change links to _blank if they don't start with a specific url/domain -

i know $("a[href='http://testtesttest.org/']").attr("target", "_blank"); find , change links match test url, i'd know how change links not match url. links take users other webites -- outside links

you can use :not:

$("a:not([href='http://testtesttest.org/'])") 

if want select don't start url, have use attribute starts selector ^=:

$("a:not([href^='http://testtesttest.org/'])") 

you mention:

essentially links take users other webites -- outside links

that depends on how consistent structure of internal urls is. e.g. previous shown selector select links such as

<a href="/images">images</a> 

or

<a href="foo/bar">bar</a> 

which internal. if every internal link starts domain name, fine. if not, either have possibility adjust links, have consistent structure, or use selector:

$("a[href^='http']:not([href^='http://testtesttest.org/'])") 

this make sure links absolute , relative urls not selected.

if have links other protocols, such file:, becomes more involved.
