jQuery Mobile - Dynamic Toolbars


You can inject toolbars dynamically on the click of a button. You need to update the page height and padding by invoking the following function.



Following example demonstrates the use of dynamic toolbars in jQuery Mobile.

<!DOCTYPE html>
      <title>Dynamic Toolbars</title>
      <meta name = "viewport" content = "width = device-width, initial-scale = 1">
      <link rel = "stylesheet" href = "https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.css">
      <script src = "https://code.jquery.com/jquery-1.11.3.min.js"></script>
      <script src = "https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>
         $( document ).on( "click", "#inject-toolbars", function() {
            $( "<div data-role = 'header'><h2>Dynamic Header</h2></div>")
               .prependTo( "#page-with-dynamic-toolbars" )
               .toolbar({ position: "fixed" });
            $( "<div data-role = 'footer'><h2>Dynamic Footer</h2></div>")
                .appendTo( "#page-with-dynamic-toolbars" )
                .toolbar({ position: "fixed" });
      <div data-role = "page" class = "jqm-demos" id = "page-with-dynamic-toolbars" 
         data-url = "page-with-dynamic-toolbars">
         <div role = "main" class = "ui-content jqm-content jqm-fullwidth">
            <h2>Page content</h2>
            <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do 
            eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad

            <div data-demo-html = "#page-with-dynamic-toolbars" data-demo-js = "true">
               <button id = "inject-toolbars" class = "ui-btn ui-btn-inline 
               ui-corner-all">Inject toolbars</button>
