driver= webdriver.Firefox()
driver.get("https://www.python.org")

with open('/path/to/jscode.js') as f:

Hope this helps Here is a good read on understanding what you are doing: Eval embed JavaScript Ajax: YUI style
Making your code work with using eval(); but its not recommend for various reasons:
code :
<script type="text/javascript">
    function result() {
        alert("Success");
    }
</script>
These Are The Results
if (xmlhttp.readyState==4)/* && xmlhttp.status==200) */
        {
            document.getElementById("divResults").innerHTML=xmlhttp.responseText;
            result(); // this function is embedded in the responseText
                      // and doesn't get evaluated. I.e. it doesn't exist
}
if (xmlhttp.readyState==4)/* && xmlhttp.status==200) */
        {
            document.getElementById("divResults").innerHTML=xmlhttp.responseText;
            var myDiv = document.getElementById("divResults");
            var myscripz = myDiv.getElementsByTagName('script');
            for(var i=myscripz.length; i--;){
                   eval(myscripz[i].innerHTML);
            }
            result(); //alerts success
}
 echo 'These Are The Results';
xmlhttp.onreadystatechange=function()
{
    if (xmlhttp.readyState==4)/* && xmlhttp.status==200) */
    {
        document.getElementById("divResults").innerHTML=xmlhttp.responseText;
        alert('success'); // or whatever else JavaScript you need to do
    }
}

Does that help Are you sure the class file is on the classpath (as well as js.jar)?
Try
code :
java -cp .;js.jar HelloWorld

Check browser width and execute a Javascript file and override another Javascript


By : Kamesh.Sethu

help you fix your problem Problem was fixed.When I copy/pasted two JS files into the if/else statement, something broke the "if" statement so "else" was always being executed.I confirmed this by swapping the mobile and desktop versions and changing ">" to "<".In that case only desktop version would load.
Instead of copy/pasting the entire JS files into else/if, I left the common part out and added only the portion that was different in desktop/mobile version.Sounds simple, but it didn't come to my mind at the beginning.

How do I execute Javascript only after a deferred Javascript external file has loaded?


By : Maxim Popkov
Date : March 29 2020, 07:55 AM
I hope this helps . This can be achieved by an onload function.
You can dynamically load each... This example is pulled right from MDN. It will insert your external resource above the script you call importScript() then launch the callback after loading.
code :
function importScript (sSrc, fOnload) {
  var oScript = document.createElement("script");
  oScript.type = "text\/javascript";
  oScript.defer = true;
  if (fOnload) { oScript.onload = fOnload; }
      document.currentScript.parentNode.insertBefore(oScript, document.currentScript);
  oScript.src = sSrc;
}
importScript("//external.otherdomain.com/path/js/myresoures.js", function () { _satellite.pageBottom(); });
$.getScript( "//external.otherdomain.com/path/js/myresoures.js", function () {_satellite.pageBottom();} );
