JavaScript Not Working on JSFiddle.net
The provided code works on a live site but fails to run on JSFiddle.net, generating errors such as "ReferenceError: fillList is not defined" and "ReferenceError: mySelectList is not defined."
Explanation:
The error occurs because the functions referenced in the HTML ("fillList()" and "findIt()") are defined within the "window.onload" function. In this context, these functions are only accessible within the onload function and cannot be referenced as global variables.
Solution:
To resolve this issue, you have three options:
Change Function Definition:
Unobtrusive JavaScript:
Adjust JSFiddle Settings:
Recommendation:
Option b (unobtrusive JavaScript) is the recommended approach as it follows best practices for separating HTML from logic. This promotes maintainability and improves code reusability.
