Mastering Page Redirection with JavaScript and if Statements

Have you ever wanted to send users to different web pages based on their feedback? This is a common feature in many web applications where user input can determine their next experience. In this guide, we’ll explore how to achieve this using JavaScript’s if statements for a smooth redirection process.

The Problem: Incorrect Page Redirection

Consider this example: you have a feedback system on your website with three different HTML pages:

You want to redirect users to either the positive or negative review pages based on their emoji feedback selection. However, there seems to be an issue with redirection; your current code is not functioning correctly and always redirects to the positive review page. Let's break down how to fix this.

The Original Code: What's Wrong?

Here’s the problematic code:

Issues Identified:

The code loops through all experience elements, which means it might set a conflicting redirection if more than one rating is present.

The Solution: Refined Redirection Logic

To correct the redirection process, we can simplify our approach. Instead of looping through all the elements, we should directly retrieve the currently selected rating. Here’s how to do it effectively:

Step 1: Select the Active Rating

You need to identify which emoji was selected by the user. This can be accomplished by querying for the element that is marked as active. Here’s the code snippet to do that:

With the if statement, it checks the text inside the selected emoji:

Conclusion: Implementing the Solution

By simplifying your approach and focusing on the active rating element, you can effectively manage page redirection based on user feedback. Remember, code readability is just as important as functionality. Always strive for clarity in your code, especially when handling user interactions.

This guide gives you a clear pathway to implementing redirection in your web applications using JavaScript. With the correct use of if statements and DOM manipulation, you can ensure that users have a smooth experience based on their inputs.
