    $('.addPart').click(function() {    
            myClone =开发者_如何转开发 $('#template').clone();           
            myClone.attr("id", "template-" + counter);  
            counter++;
            myClone.appendTo("#placeholder").trigger( "create" );
            // myClone.appendTo("#placeholder").page(); does not work in this version?

        return false;
    });   

    // Toggle Show/Hide HTML
    $('.preShowHTML').click(function() {    
         $("#HTMLOut").text($("body").html());
         $("#HTMLOut").toggle();
        return false;
    });             
});
</script>

I think the counter is in the wrong place. However this does not make the example any more functional.

myClone = $('#template').clone();           
myClone.attr("id", "template-" + counter);  
//counter++;
myClone.appendTo("#placeholder");
$('#template-'+counter).page();                
counter++;

I am not sure that this is correct approach - cloning html after jquery mobile has applied it's listeners and formatting.

AJAX might make it slightly cleaner but here is a start:

$(document).ready(function(){
    $("div").live("pageshow", function () { 
        counter = 0;
        $(".addPart").click(function() {    
                counter++;
                $("#placeholder").append('<div  id="template-'+counter+'"><div data-role="fieldcontain"><input type="range" name="slider" class="ui-slider-input ui-input-text ui-body-null ui-corner-all ui-shadow-inset ui-body-c" id="slider'+counter+'" value="0" min="0" max="100" /></div></div>');
                $("#template-"+counter).trigger("create");

            return false;
        });   

    });
});
</script>
