I have a javascript file named “a.js” located in host a.
The code in a.js is as below:

function sayHello() {
    alert("Hello, world");
}

I have a html file named b.html located in host b, in which there are code like below:

<html>
  <head>
    <script type="text/javascript" src="http://a/js/a.js" />
    <script type="text/javascript">
      sayHello();
    </script>
  </head>
  <body>
  </body>
</html>

When I key in the url “http://b/b.html&#8221; in my browsers (I have tested in IE8, Chrome), my browsers don’t pop the alert window. Did I miss something configuration ?

How should I do so that my b.html can include a javascript file which is located in another host and the functions in the javascript file can be executed just like we include Google’s javascript API files ?

Thank you for your help.

    You’re having this problem because the <script> tag is not self-closing (unless you’re serving your file with a XML content-type). As Dr.Dredel said, in this case it’s not related to any kind of security restriction. Change your markup to:

    <script type="text/javascript" src="http://a/js/a.js"></script>

    Further reference: Why don’t self-closing script tags work?
