javascript - 基于触摸旋转对象(Rotating an object based on touch)

Question

I am available to rotate an html object with JavaScript based on touch, but whenever I touch the screen again, it rotates to that value instead of rotating relative to its rotations

(我可以使用基于触摸的JavaScript旋转html对象，但是每当我再次触摸屏幕时，它都会旋转到该值，而不是相对于其旋转旋转)

var obj = document.getElementById("obj");
var x1;
function rotate(event) {
    x1 = event.touches[0].clientX + (window.innerWidth / 2);
    var objRx = 360 / (window.innerWidth / x1);
    obj.style.transform = "rotateY(" + objRx + "deg)";
}
