How to Retrieve Hidden Input Values Using jQuery in Buttons

In web development, it’s common to use hidden input fields to store data that’s not displayed to the user. But how can we retrieve the value of these hidden inputs when a related button is clicked? In this guide, we’ll explore a practical example to demonstrate exactly how to do this using jQuery.

The Problem

Imagine you have a table where each row contains a button and an associated hidden input field. The task is to retrieve the value of the hidden input field when the corresponding button is pressed. Here’s an example of what our HTML table looks like:

In this table, if you press the DEL button for the row corresponding to the hidden input with id_3, we want to retrieve its value.

The Solution

To achieve this, we can use jQuery. Here’s how we do it step by step:

Step 1: Select the Button

We want to attach a click event listener to all buttons that have an id starting with bttn_. This can be accomplished using the $('button[id^=bttn_]') selector.

Step 2: Get the Hidden Input Value

Once a button is clicked, we can use $(this).siblings("input") to find the associated hidden input and retrieve its value using .val(). Here's the jQuery code:

Conclusion

With just a few lines of jQuery code, you can easily retrieve specific hidden input values associated with buttons in a table. This allows you to handle actions dynamically based on the data stored in hidden fields. Whether you are building a dynamic user interface or managing form submissions, this technique will prove to be very useful!
