How to Collect Checkbox Values in JavaScript and Display Them in an Input Field

When creating web forms, you may want to allow users to select multiple options. For instance, using checkboxes enables users to choose various items, and sometimes you might need to collect all the values they select to display them somewhere else on the page. This is a common requirement when creating forms for services or products. In this guide, we will explore how to extract values from multiple checkboxes and display them in a text input field using JavaScript.

Understanding the Problem

Let's say you have a form with several checkboxes representing different options (like "Glass", "Frame", and "Folding") and a button to submit the choices. You noticed that when the user selects checkboxes and clicks the button, only the last selected checkbox value is displayed in the input field. This happens because each time you set the input value, it overwrites the previous one.

Solution Breakdown

To fix this issue and gather the values from all checked checkboxes, we need to make some adjustments to the existing JavaScript code. Here’s how to do it step-by-step.

1. Clearing Previous Input Value

Before starting to collect values, we should clear any previous values in the text input field. This ensures that each time the button is clicked, only the current selections are shown.

2. Loop Through Checkbox Selection

Next, you will loop through each checkbox to check if it is selected (checked). If a checkbox is checked, we will add its value to the text input.

3. Concatenate Values

Instead of overwriting the input value, we will concatenate the current checkbox value to the existing text in the input field. This will allow us to display all selected values.

Conclusion

With this simple addition and modification, you will now be able to collect values from multiple checkboxes and display them in a text input field effectively. This technique is not only practical for user form submissions, but it also enhances user experience by giving instant feedback on their selections. Remember to always clear previous input before displaying new selections, and concatenate values instead of replacing them.

Now you're ready to implement this feature in your web projects with ease! If you have any questions or need further assistance, feel free to ask. Happy coding!
