Tips for utilizing data from one JavaScript file in another JavaScript file

In my current setup, I have two JavaScript files - a.js and b.js. The input data is stored in a.js, while the unit tests are written in b.js. Now, the challenge I am facing is how to access the input data from a.js in b.js. I understand that both files can be included in an HTML page, but since b.js contains qUnits for testing JavaScript methods (similar to jUnits) which are run from a build.xml file, using HTML is not an option.

I initially attempted to call the methods of a.js from b.js, given that they are in the same directory. However, this approach did not yield the desired results.

Are there any alternative methods that I could employ to utilize the data from a.js in b.js? Any insights or suggestions would be greatly appreciated.

Answer №1

While working in file b.js, include the following code:

$(document).ready({
$.ajax({
url: "",
context: document.body
}).done(function() {

});
});

You can then use this AJAX call to retrieve the content of a.js and integrate it into any part of the current page as needed.

If you're looking to include a Javascript file within another, check out this helpful answer

Simply put, there are two primary methods for achieving this (taken from the aforementioned answer) :

  • Utilize an Ajax call to load it and then use eval.
  • Insert a script tag with the script URL in the HTML.

Answer №3

File a.js contains the following code:

myGlobalData = {}
myGlobalData.info = {x: 'great', y: 'z'}

Now let's utilize myGlobalData in file b.js:

if(myGlobalData) {
   function accessGlobalVariable() {
        alert(myGlobalData)
   }
}
