Swipe Gesture

This code sample demonstrates how to detect left and right swipe gestures on an element. It initializes Hammer.js on a target element and listens for 'swipeleft' and 'swiperight' events.

var myElement = document.getElementById('myElement');
var mc = new Hammer(myElement);
mc.on('swipeleft swiperight', function(ev) {
    console.log(ev.type + " gesture detected.");
});

Pinch Gesture

This example shows how to enable and detect pinch gestures. It sets up pinch gesture recognition on an element and logs the scale of the pinch gesture.

var myElement = document.getElementById('myElement');
var mc = new Hammer(myElement);
mc.get('pinch').set({ enable: true });
mc.on('pinch', function(ev) {
    console.log("Pinch gesture detected with scale: " + ev.scale);
});

Rotate Gesture

This code snippet enables rotation gesture detection on an element. When a rotate gesture is detected, it logs the rotation angle.

var myElement = document.getElementById('myElement');
var mc = new Hammer(myElement);
mc.get('rotate').set({ enable: true });
mc.on('rotate', function(ev) {
    console.log("Rotate gesture detected with angle: " + ev.rotation);
});
