jQuery Mobile: Markup Enhancement of Dynamically Added Content
Introduction
Enhancement of dynamically created content ensures that it adheres to jQuery Mobile's distinctive styling. This process is crucial but also resource-intensive, so selective enhancement is advised based on the component being updated.
Enhancement Levels
Three enhancement levels exist, categorized by their resource consumption:
- Enhance a single component/widget
- Enhance page content
- Enhance entire page content
Enhance a Single Component/Widget
Note: Enhancement methods must be used only on the current/active page. Enhancements on dynamically inserted pages will occur once they are inserted into the DOM.
Example: Enhancing a button:
$('[type="button"]').button();
Enhance Page Content
$('#index').trigger('create');
Enhance Entire Page Content
Caution: trigger('pagecreate') should only be used sparingly, as it carries the risk of unintended side effects.
$('#index').trigger('pagecreate');
Methods to Prevent Markup Enhancement
To prevent enhancement of specific elements, use one of the following methods:
Method 1:
data-enhance="false"
Method 2:
data-role="none"
Method 3:
$(document).bind('mobileinit',function(){
$.mobile.page.prototype.options.keepNative = "select, input";
});
Markup Enhancement Problems
Error: "cannot call methods on listview prior to initialization"
Solution: Initialize the component before enhancing the markup:
$('#mylist').listview().listview('refresh');
Markup Overriding Problems
To override default jQuery Mobile CSS styles, use !important flags in CSS rules.
Example:
#navbar li {
background: red !important;

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.
