Solving the Issue of Jquery API Value Not Working in Input Textarea

In the world of web development, particularly when working with live data such as cryptocurrency prices, developers often encounter issues while trying to update input elements dynamically. One common problem arises when using jQuery and the API to fetch live data but facing challenges in displaying that data in an <input> field.

In this guide, we’ll explore a specific question raised by a developer: Why is the jQuery API value not working in an input textarea? We will also provide a clear solution and tips for implementing it correctly.

Understanding the Problem

The developer is trying to display the current price of Bitcoin fetched from the CoinGecko API in an <input> element. The approach works perfectly when using headings (<h2>) but fails when trying to populate an input field (<input type="number">).

Key Points:

The API returns a live price, but the method of setting the value in the input is incorrect.

While innerHTML works for non-input elements, it does not work for form controls like <input>.

Breaking Down the Solution

The core of the problem lies in the way we attempt to update the <input> element with the fetched price. Below are the steps and the corrected code to ensure that the value from the API is displayed correctly in the input field.

1. Identify the Input Element

First, we need to correctly reference the input element in our JavaScript:

Conclusion

In summary, when working with jQuery and inputs, it’s vital to remember that input elements do not have an innerHTML property. Instead, you should directly manipulate their value property to reflect the changes. This approach not only remedies the problem but ensures that users receive real-time updates on cryptocurrency prices.
