Passing Data to a Bootstrap Modal
Modal windows are a common element in user interfaces, allowing users to interact with specific content without leaving the current page. This article discusses a solution to the problem of passing data to a modal upon opening it.
Problem:
Web developers often encounter the need to pass data from a hyperlink to a modal window. For example, consider a user interface with hyperlinks that have unique IDs attached. When clicked, these links should open a modal window and pass the IDs to the modal. However, many developers face difficulties in implementing this functionality.
Solution:
One effective solution to this problem is to utilize jQuery's .on event handler. Here's a step-by-step explanation of how to achieve data passing:
- HTML Markup: Define hyperlinks with data attributes containing unique IDs. Include a hidden input field within the modal to capture the passed data:
<a data-toggle="modal" data-id="ISBN564541" class="open-AddBookDialog">Link 1</a> <div class="modal hide">
- JavaScript: Bind the click event to the hyperlinks and extract the data attribute values. Update the hidden input within the modal accordingly:
$(document).on("click", ".open-AddBookDialog", function () {
var myBookId = $(this).data('id');
$(".modal-body #bookId").val(myBookId);
});
- Optional: If desired, display the modal by manually calling the modal('show') function:
$('#addBookDialog').modal('show');
Additional Notes:
- The provided solution utilizes delegated event handling, which is more efficient than binding events to individual elements.
- It is unnecessary to manually call the modal('show') function, as the click event on the modal toggle element will automatically display the modal.
By following these steps, developers can effectively pass data from hyperlinks to modal windows, enhancing user experience and simplifying development workflows.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
