錘子js：pinchend有時不會開火

Question

我使用pinchin ， pinchout和pinchend 。 如果這是一個漫長pinchin或pinchout的pinchend火災確定，但如果它是一個短pinchin或pinchout的pinchend不火。 這是一個錯誤還是我做錯了什么？

gestos = new Hammer.Manager(document.body, {
    touchAction: "manipulation"
});
gestos.add(new Hammer.Pinch({event: 'pinch'})); // If it isn't added, pinchout and pinchend never fires 
gestos.add(new Hammer.Pinch({event: 'pinchin'}));
gestos.add(new Hammer.Pinch({event: 'pinchout'}));
gestos.add(new Hammer.Pinch({event: 'pinchend'}));
gestos.on("pinchin pinchout pinchend", function (e) { 
    if (e.type == "pinchin")
        interact("#mapa").resizable(false);
    else
        interact("#mapa").resizable(true);
    console.log(e.type);
});

Answer 1

gestos.add(new Hammer.Pinch({event: 'pinchcancel'}));
gestos.on("pinchin pinchout pinchend pinchcencel", function (e) { 
    if (e.type == "pinchin")
        interact("#mapa").resizable(false);
    else
        interact("#mapa").resizable(true);
    console.log(e.type);
});
//sometimes the device just recognize our move as pinchcancel when we actually want to fire pinchend event.
