<div data-role="header" data-position="fixed" class="wow fadeIn">
            <a href="#leftpanel" class="ui-btn ui-btn-left"><i class="zmdi zmdi-menu"></i></a>

            </ul>

        </div>

I have nativeDroid2b Tabs jquerymobile material design from natriveDroid2/Tabs.

How can I enable swipe feature in this tabs (ie switch between tabs content).

I wrote code for this, but it's not working:

$(function () {
            function changeNavTab(left) {
                var $tabs = $("div[data-role=nd2tabs] li ", $("div[data-role=nd2tabs].nd2Tabs-active"));
                var curidx = $tabs.closest("li.nd2Tabs-active").parent().index();
                console.log($tabs);
                var nextidx = 0;
                if (left) {
                    nextidx = (curidx == $tabs.length - 1) ? 0 : curidx + 1;
                } else {
                    nextidx = (curidx == 0) ? $tabs.length - 1 : curidx - 1;
                }
                $tabs.eq(nextidx).click();
            }

            $("div[role=main]").on("swipeleft", function (event) {

                changeNavTab(true);
            });

            $("div[role=main]").on("swiperight", function (event) {

                changeNavTab(false);
            });
        });

Kindly help me, thanks in advance.

回答1:

First, use pagecreate instead of the regular jQuery document.ready:

$(document).on("pagecreate", "#page1", function () {
    $("div[role=main]").on("swipeleft", function (event) {
        changeNavTab(true);
    });

    $("div[role=main]").on("swiperight", function (event) {
        changeNavTab(false);
    });
});

Next, in changeNavTab(), the selector should be ul[data-role="nd2tabs"] instead of div[data-role="nd2tabs"]:

function changeNavTab(left) {
    var $tabs = $('ul[data-role="nd2tabs"] li');
    console.log($tabs);
    var len = $tabs.length;
    var curidx = 0;
    $tabs.each(function(idx){
        if ($(this).hasClass("nd2Tabs-active")){
            curidx = idx;
        }
    });

    var nextidx = 0;
    if (left) {
        nextidx = (curidx >= len - 1) ? 0 : curidx + 1;
    } else {
        nextidx = (curidx <= 0) ? len - 1 : curidx - 1;
    }
    $tabs.eq(nextidx).click();

}
