Executing code inside a

Question

Why does this snippet:

<script type="text/javascript">
alert("1111");
</script>  

<script type="text/javascript" src="xxx.js">
</script>

result in "1111" being alerted, but this one:

<script type="text/javascript" src="xxx.js">

alert("111");
</script>

doesn't cause "111" to alert? Is it not possible to put code in the same <script> tag that loads an external script?

Well, this is just how the <script> tag works. If you have a src attribute, the content of the tag gets ignored.

Simply use another <script> tag, what's the problem with that?

The below JavaScript is correct:

<html>
     <head>
          <script type="text/javascript"> alert("1111"); </script>
          <script type="text/javascript" src="xxx.js"> </script>
     </head> 
     <body>
          <p> The actual script is in an external script file called "xxx.js".</p>
     </body>
</html>

If you only want one script tag then put the

 alert("1111");

inside of the xxx.js file.

The alert doesn't work when it is placed in between the script tag with a src because that is the way it is intended to work. It ignores anything between the open and closing script tags when src is specified.
