How to Generate Multiple select Inputs in Vue.js with v-for from JSON Data

When building web applications using Vue.js, you may encounter situations where you need to generate multiple select inputs based on data retrieved from a backend API. This can pose a challenge, especially if the JSON structure received is not optimized for your needs. In this post, we'll walk through an example of generating select inputs using the v-for directive in Vue.js and discuss how to improve upon the original JSON structure for better usability.

The Problem

Imagine you are working with a JSON response from an API that contains data for multiple selects. The initial JSON structure may look something like this:

However, you may find it challenging to effectively create the select inputs in your Vue.js application based on this structure. Let’s see how to resolve this.

The Solution

Step 1: Update the JSON structure

After some thought and experimentation, the first significant improvement involves modifying the JSON data from the backend to better fit your needs. An improved structure could be:

Step 2: Update the Vue.js Template

Now, with the modified structure, let’s update the Vue.js template to generate multiple select inputs. Here’s how you can do that:

Step 3: Update the Vue.js Script

You will want the script to still handle data fetching and the organization of your selected values. The following is how the script might look:

Conclusion

By updating the JSON structure and using v-model for two-way data binding, we simplify the select input management. This transformation not only enhances the readability and usability of your form but also promotes easier maintenance and extensibility.

Remember, the key to building effective forms in Vue.js is understanding the JSON data you’re working with and leveraging Vue’s powerful directives like v-for and v-model. These changes can be hugely beneficial for those struggling with similar implementations. Happy coding!
