javascript - jQuery: object is not a function -


i've been trying toggle 2 .pngs on button click. when run code, console throws error: uncaught typeerror: object not function. here code:

<body> <h1>my website</h1>  <div> <button data-file="bs">bmw </button> <button data-file ="ms">mercedes</button> </div>  <div id="bmw"> <img src="bmw.png"> </div>  <div id="mercedes"> <img src="merc.png"> </div>  <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>  <script>  (function () {     var link = $('link');     $('button').click(function () {         var $this = $(this)         car = $(this).data('file');         console.log(car);         link.attr('href', car + '.png');     }); })(); </script>

which object referring to? , how alter code?

thanks in advance!

$('link') invalid. there no html tag called 'link'. might want is

<button data-image-id='bmw'>bmw</button> <button data-image-id='merc'>mercedes</button>  <img src='bmw.png' id='bmw' /> <img src='merc.png' id='merc' />  (function() {     $('button').click(function() {         var button = $(this);         var imageid = button.data('image-id');         var image = $('img#' + imageid);         image.toggle();     }); })();

when button clicked, gets button's data-image-id, finds image id , toggle image.
