Why won't my jquery work -

i have more code important bit. rest of js function , styling.

        <button onclick="gb()" id="gb"> clickme</button>         <script  src="jquery-1.12.2.min.js">             $( document ).ready(function() {                 $('button').eq(0).trigger('click');                 }; 

you can't mix <script> tag src and inner script. make 2 tags

<script src="jquery-1.12.2.min.js"></script> <script>     // script </script> 

also, check console while developing. point out errors you.
