javascript - $(...).popover is not a function -


i have looked through quite few posts on here dealing issue, none of them seem solve problem.

i have imported jquery , bootstrap js files in right order. things such bootstrap panels working fine me.

my script imports this:

   <script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>    <script src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js"></script>    <link href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css" rel="stylesheet"> 

however, when try

 $('[data-toggle="popover"]').popover(); 

i following message in chrome console:

 uncaught typeerror: $(...).popover not function 

at first thought maybe popover not being included in cdn's copy, went ahead , downloaded local copy plugins included here:

http://getbootstrap.com/customize/ 

and got same error message (re-pointed script tags towards local js file).

doing search "popover" bootstrap.min.js file:

http://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js 

shows popover included in file.

since have stated have included jquery , other libraries correctly, 1 possible case there multiple instances of jquery in page.

so based on server technology used, search duplicate version of jquery , if there remove them(if not needed else have think noconflict() use).

in case of duplicate jquery instances problem jquery version plugin attached might different 1 accessing use plugin @ point plugin not found.
