How to Dynamically Change the Data Source of a Table on Dropdown List Change

When building interactive web applications, you may often need to dynamically update displayed content based on user input. One common requirement is to change the data shown in a table when a user selects a different option from a dropdown list. In this guide, we will cover how to change the data-source of a Bootstrap table on the change of a dropdown list, using the example of a customer dropdown and associated products or services.

Understanding the Problem

In our scenario, we have a dropdown list of customers, and a Bootstrap table that shows various products or services provided by the selected customer. Initially, the table is populated with data of "Customer 0". However, upon changing the dropdown selection, we need to refresh the table with the relevant data for the newly selected customer.

Initial Setup

Here’s a quick overview of our HTML structure:

A dropdown list for customer selection (customerFilter).

An informative toolbar above the table.

A Bootstrap table configured to display product details.

Implementing the Solution

We will implement a function to change the data source of the Bootstrap table whenever the dropdown list changes. Let’s break this down into clear steps:

Step 1: Adding the Change Event Listener

First, we need to set up an event listener on the dropdown list (# customerFilter). This listener will trigger each time the user selects a new customer.

Step 2: Defining the Change Function

In the customerFilterChanged() function, we will handle the change of the dropdown value. Our goal is to update the data source URL for the table based on the selected customer:

Step 3: Updating the Table Data Source

As shown in the function above, we use $('# table').bootstrapTable('refresh', { url: url }); to change the table's data-source and refresh the displayed data based on the selected customer.

Step 4: Updating the Controller

To support this dynamic data-source, we should ensure our backend controller can handle requests for different customers and send the appropriate data:

Step 5: Setting the Initial Data URL in the Table

When the page first loads, we must configure the table's data-url attribute to point to the initially selected customer. Here’s how to do it:

Conclusion

Now, when a user selects a different customer from the dropdown list, the Bootstrap table will refresh itself and display the corresponding services/products for that customer. This dynamic data presentation enhances user experience by providing real-time updates based on their input.

By following the steps outlined in this guide, you have learned how to effectively change the data source of a Bootstrap table based on dropdown list selections. Happy coding!
