B.js:

  validation();

}

Answer 1

include the a.js file to b.js

function includeJs(ajsfilepath) {
    var js = document.createElement("script");

    js.type = "text/javascript";
    js.src = jsFilePath;

    document.body.appendChild(js);
}

includeJs("/path/a.js");

Answer 2

If you don't want to use scripting to dynamically include the javascript files, you can add the following lines in your html file:

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

Then, it should work.
