How to Synchronize Table Sorting with jQuery: A Step-by-Step Guide

When working with multiple related tables in a web application, particularly when sorting or arranging data, it's essential to ensure that the relationship between these tables is maintained. A common scenario is where one table needs to be sorted based on user input and a second table must reflect the same changes without direct overlap in their data.

In this guide, we'll explore a practical example of synchronizing two tables using jQuery. We will focus on resolving the issue of arranging the second table based on the changes made to the first.

Problem Overview

Imagine you have two tables that relate to a common data field, such as "Container No." Here’s the challenge:

Table 1 contains container numbers that can be rearranged by the user.

Table 2 may contain multiple rows of container numbers but does not contain the same values as Table 1.

When Table 1 is sorted, Table 2 must rearrange its rows to match the new order of related container numbers.

Current Setup

The user manually sorts Table 1, while Table 2 must adjust its rows to reflect this new order. The existing code uses a combination of jQuery functions to accomplish this, but it encountered issues especially with row behaviors being lost during cloning.

Solution Breakdown

Let’s take a look at how we can effectively synchronize Table 2 with Table 1 when changes occur. Below, we’ll break down the solution into clear steps:

Step 1: Capture the Sorted Order of Table 1

We first need to gather the sorted container numbers from Table 1:

This snippet creates an array of all the container numbers once the first table has been sorted.

Step 2: Arrange Table 2 Based on Table 1's Order

Next, we will iterate over these captured container numbers and reorder Table 2 accordingly:

Step 3: Maintaining Event Handlers and Behavior

One common issue encountered was the loss of event handlers or behaviors attached to the rows in Table 2 due to the use of the clone() function. To avoid this, we directly move the existing rows instead of cloning them, ensuring that all behaviors remain intact.

Step 4: Implementing the Solution

Now, you can use this entire approach to create a robust mechanism that maintains the relationship between both tables:

Capture sorted container numbers from Table 1.

Reinsert corresponding rows from Table 2 in the new order, preserving behaviors.

Ensure there’s no duplication or loss of data.

Example of the Final JavaScript Code

Here is the combined solution that captures the sorted values and rearranges Table 2 accordingly:

Conclusion

By following these steps, you can effectively synchronize the sorting of two related tables in your web application using jQuery. This not only improves the user experience but also ensures that the data remains consistent and accurately reflects the intended order.
