[Solved] What am I doing Wrong? HTML and Javascript [closed]

You have a fundamental misunderstanding as to how this code will be executed. As the page loads, once the browser encounters a <script> element with code not contained (i.e., within a function), it will execute that script.

So, when your page loads, it looks at your <script> block and:

  1. Sets the variable q to 13.
  2. Compares q to 12 using the less than (<) comparator.
  3. Since the above conditional is false, it will not step into the brackets.

Your button sets q to 11, but that is irrelevant at that point in the code, because it no longer checks the conditional. Use Javascript functions to achieve the functionality you desire:

<html>
    <head>
    </head>
    <body>

        <script type="text/javascript">
        function compare(q) {
            if(q < 12) {
                alert("clear");
            }
        </script>

        <button onclick="compare(11)">clear</button>

    </body>
</html>
