Question

我正在使用pinchin，pinchout和pinchend。如果长pinchin或pinchout pinchend可以点火，但如果它是短pinchin或pinchout则pinchend不会触发。这是一个错误还是我做错了什么？

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.

锤子js：pinchend有时不会开火
