Instead of: <script src=/scripts/myJsFile.v1.js type=text/javascript></script> Have something like <script src=/scripts/myJsFile. + versionVar + .js

Instead of:

<script src="/scripts/myJsFile.v1.js" type="text/javascript></script>

Have something like

<script src="/scripts/myJsFile." + versionVar + ".js" type="text/javascript></script>

This way when we update the js version files the user won’t have to clear their cache.

    Not in that way, because you’re mixing HTML and JavaScript together. HTML does not have JavaScript variables available.

    What you can do, however, is adding the <script> tag dynamically, i.e. through JavaScript. That way, you obviously are able to use variables:

    <script>
var versionVar = "1.0";

window.addEventListener('load', function() { // on load

    var scriptTag = document.createElement('script'); // create tag
    scriptTag.src = "/scripts/myJsFile." + versionVar + ".js" // set src attribute
    scriptTag.type = "text/javascript"; //set type attribute
    document.getElementsByTagName('head')[0].appendChild(scriptTag); // append to <head>

}, false);
</script>
