How Can I Efficiently Enhance Dynamically Added Content with jQuery Mobile?

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:

1. Enhance a single component/widget
2. Enhance page content
3. 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;
}
