You have encountered a common issue when working with external JavaScript files – accessing global variables across multiple files. Your goal is to determine if a function from helpers.js has been called, and you attempted to create a global variable named myFunctionTag in both the HTML code and helpers.js.
Unfortunately, your approach is not feasible. The issue arises because the HTML code includes the helpers.js file after defining the global variable in the HTML. As a result, the variable in the HTML code overrides the one in helpers.js, leaving you with a false value even when the function has been called.
To resolve this issue, you need to declare the global variable before including the helpers.js file. By creating a script tag and defining the variable above the include, you ensure that the variable is available throughout all the JavaScript code. Here's how your updated code should look like:
