This is not informative !
Your browser have a developer console which show you error messages and problems in JS.
First of all you should spend some time to learn properly html, JS and Jquery.
W3Schools Online Web Tutorials[^]
JavaScript Tutorial[^]
jQuery Tutorial[^]

Any html page is compound of a <header> and a <body>. This is html 101.
When you open a tag, you also must close it:

HTML

<title>njfhdf</title>

Js code should be enclosed in <script> tags
JS lines should end with ';'

JavaScript

arr_val = $ ("#arr_val").val();
arr.append(arr_val);

Declaration of a variable must be done only once:

JavaScript

var arr = [];
var arr = []

Each one of those is enough to have a 'not work'.
And I have not even tried to see what your code is supposed to do.
