Novice one, would you please tell me why the jquery code is not running? .js file already on the web page with catalogue,

<meta charset="utf-8">
</script>
<script>
JQuery (document). Ready (function () {
$(" input [type='button'] "). Click (function () {
# var inputValue=https://bbs.csdn.net/topics/$(" test "). Val ();
Alert (inputValue);
});
});
</script>
