How to Update Input Values in a Specific Div using jQuery

When you are working with multiple input boxes within divs that share the same class, it can be a challenge to update the values of these inputs individually. Many developers encounter situations where changing an input value inadvertently updates all inputs across different divs. In this guide, we will address this common issue and provide a straightforward solution using jQuery.

The Problem: Single Input Update Affecting All Inputs

Imagine you have multiple divs that each contain several input boxes. You want to ensure that when you change the value in one input box, only the input boxes within that specific div are updated. Here’s what you might be facing:

In the example above, changing one input's value might lead to all inputs across different divs being updated together, which is not the desired outcome.

The Solution: Using .siblings() in jQuery

To achieve the desired functionality where only the inputs within the same div are updated, we can utilize jQuery's .siblings() method. This method allows you to select sibling elements of an input and adjust their values accordingly.

Step-by-step Implementation

How It Works

Change Event: The code listens for a change event on any input with the class .js-qty.

Sibling Updates: Using $(this).siblings(), we select only the sibling inputs in the same div and update their values to match the one that just changed.

Conclusion

In summary, using jQuery's .siblings() method allows you to control which inputs are updated when a single input's value changes. This feature provides an effective solution for dealing with grouped inputs inside common parent elements.
