It is possible to run javascript from a file.
Run JavaScript ${CURDIR}/js_to_run.js
However, I am wondering how to call a function by its name from this file?

Utilizing the Execute Javascript function as it comes may not allow for direct invocation of a specific function. However, it is feasible to pass the name of a function as an argument.
Execute Javascript ${CURDIR}/js/utils.js ARGUMENTS clickElement ${locator}
The script within the utils.js file:
var utils = utils || {};
(function (arguments) {
utils.clickElement = function (locator) {
// Function implementation
}
// Extracting and executing function based on passed arguments
var functionName = [].shift.call(arguments);
utils[functionName].apply(this, arguments);
})(arguments);
Although it may not be the most elegant solution, sometimes you have to get creative in order to make things work. To inject your entire Javascript code and then call the function you injected, you can use the following method.
On the Google homepage, you can inject Javascript with the following code:
var s = document.createElement('script');
s.text = "document.getElementById('hplogo').addEventListener('click',function(){alert('Google');});";
document.getElementsByTagName('head')[0].appendChild(s);
In robotframework, you can achieve the same result using Execute Javascript:
Open Browser https://www.google.com
Wait Until Page Contains Element id=hplogo
Execute Javascript var s = document.createElement('script');s.text = "document.body.addEventListener('click',function(){alert('Google')})";document.getElementsByTagName('head')[0].appendChild(s);
Sleep 2s #wait so that injected javascript gets evaluated
Execute Javascript document.getElementById('hplogo').click();
Sleep 10s #wait and click anywhere on body of the page to see the alert
Your s.text variable will contain the entire Javascript code from a JS file in a single line. While this may seem like messy work, sometimes it's necessary - as I experienced when implementing pdf export functionality on a website.
