JQuery Mobile 1.3 Select menu dynamic refresh

Question

Hi togehter i using JQM 1.3 and JQuery 1.9.1... i try to get a dynamic selectmenu working without a solution yet.

first i create a selectmenu with createDocument(div...) and .setAttribute(id,...) in the pagebeforeshow event. Then i used a lot of variations first line, second line and combined..

$("#select-keywords-list").selectmenu();
$("#select-keywords-list").selectmenu("refresh");

nothing worked yet for me..

after i added it i listen to it in the Domready($(#page).ready) function for a change event. In the browser it works very well but on the phone i just cant get it to work. Hope someone can help me.

I also tried the native menu true and false..

thank you

Answer 1

Working example: http://jsfiddle.net/Gajotres/dEXac/

$(document).on('pagebeforeshow', '#index', function(){    
    // Add a new select element    
    $('<select>').attr({'name':'select-choice-1','id':'select-choice-1','data-native-menu':'false'}).appendTo('[data-role="content"]');
    $('<option>').html('Select option!').appendTo('#select-choice-1');
    $('<option>').attr({'value':'1'}).html('Value 1').appendTo('#select-choice-1');
    $('<option>').attr({'value':'2'}).html('Value 2').appendTo('#select-choice-1');    
    // Enhance new select element
    $('select').selectmenu();

    $(document).on('change', '#select-choice-1', function(){    
        alert($(this).find("option:selected").text());
    });        
});

One more thing, don't use document ready with jQuery Mobile, they dont work correctly together. Instead use pageinit event. If you want to find more about it look here: jQuery Mobile: document ready vs page events

Answer 2

i know with a template engine its maybe easier but i tried this way

            function renderItemsKeywords(results) {
        var elementRoot = document.createDocumentFragment();
        var elementDiv = document.createElement("div");
        elementDiv.setAttribute("data-role", "fieldcontain");

        var elementL = document.createElement("label");
        elementL.setAttribute("for", "select-keywords-list");
        elementL.setAttribute("class", "select");
        elementL.appendChild(document.createTextNode("Wähle Eintrag:"));

        var elementSel = document.createElement("select");
        elementSel.setAttribute("name", "select-keywords-list");
        elementSel.setAttribute("id", "select-keywords-list");
        elementSel.setAttribute("data-native-menu", "true");

        var elementOptD = document.createElement("option");
        elementOptD.setAttribute("data-placeholder", "true");
        elementOptD.appendChild(document.createTextNode("Wähle Eintrag"));          
        elementSel.appendChild(elementOptD);

        var allKeywords = $().checkKeywords(results);

        $.each(allKeywords, function(i, item) {
            var elementOptAll = document.createElement("option");
            elementOptAll.setAttribute("value", item);
            elementOptAll.appendChild(document.createTextNode(item));
            elementSel.appendChild(elementOptAll);
        });

        //alert(elementSel.length());

        elementDiv.appendChild(elementL);   
        elementDiv.appendChild(elementSel);

        var elementDivKey = document.createElement("div");
        elementDivKey.setAttribute("id", "keylist");

        elementRoot.appendChild(elementDiv);
        elementRoot.appendChild(elementDivKey);

        return elementRoot;
    };

than the other part

                           case 'keywords':

                html = renderItemsKeywords(itemData);

                $header.find("h1").html("Title");
                $content.html(html);
                $page.page();
                $footer.find(":jqmData(role=navbar)").navbar();
                $content.find(":jqmData(role=listview)").listview();


                $("#select-keywords-list").selectmenu();
                $("#select-keywords-list").selectmenu("refresh");
                break;
            }
            $.mobile.changePage($(this));

hope you understand what im doing
