javascript - NOT a specific word at ending in regex -

-

i have strings: 

"/page/test/myimg.jpg" "/page/test/" "/page2/test/" "/page/test/other"

i want true strings starting /page/test except when ends .jpg.

then did: /^\/page\/test(.*)(?!jpg)$/. well, it's not working. :\

it should return this:

"/page/test/myimg.jpg" // false "/page/test/" // true "/page2/test/" // false "/page/test/other" // true

use negative behind anchored end:

/^\/page\/test(.*)(?<!\.jpg)$/

for clarity, regex match input *doesnt end in .jpg:

^.*(?<!\.jpg)$

edit (now must work in javascript too)

javascript doesn't support behinds, ugly option must used, says @ least 1 of last 4 characters must other .jpg:

^.*([^.]...|.[^j]..|..[^p].|...[^g])$
