Why isn’t this very simple JQuery working?

I was trying to pass the width of a page as a variable to C# code behind asp.net, and was only receiving empty strings. I narrowed down to the problem that the JQuery function is simply not firing. I changed it to the simplest code I could just to test if the function was doing anything:

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js">
    $(document).ready(function() 
    {
           alert("hello");
    });
</script>

And yet, it still does nothing.

1. I’ve included JQuery
2. I’ve triple checked my syntax
3. No errors are reported in the console
4. I looked through the other similar SO ‘facepalm’ questions, but none of their solutions work (see above)

What incredibly obvious thing am I missing?

Method 1

You can’t simultaneously set the [src] attribute and include contents for the <script> element.

If you need two scripts, you need to use two separate <script> elements.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script>
    jQuery(function($) {
        alert("hello");
    });
</script>

As per the HTML5 spec on the <script> element:

If there is no src attribute, depends on the value of the type attribute, but must match script content restrictions.
If there is a src attribute, the element must be either empty or contain only script documentation that also matches script content restrictions.

Method 2

It should be

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js">
</script>

<script type="text/javascript">
    $(document).ready(function() 
    {
           alert("hello");
    });
</script>

Here is a post that explains this clearly-

What if script tag has both “src” and inline script?
