Elementor將背景圖片設為固定,但IE、EDGE上下滑動時,圖會抖看的很不舒服
這段程式碼是由這裡找的:为什么在IE上滚动时固定的背景图像会移动?
雖然沒有很懂,但套用下面這段程式碼解決。

 if(navigator.userAgent.match(/Trident\/7\./)) {
    $('body').on("mousewheel", function () {
        event.preventDefault();

        var wheelDelta = event.wheelDelta;

        var currentScrollPosition = window.pageYOffset;
        window.scrollTo(0, currentScrollPosition - wheelDelta);
    });

    $('body').keydown(function (e) {

        var currentScrollPosition = window.pageYOffset;

        switch (e.which) {

            case 38: // up
                e.preventDefault(); // prevent the default action (scroll / move caret)
                window.scrollTo(0, currentScrollPosition - 120);
                break;

            case 40: // down
                e.preventDefault(); // prevent the default action (scroll / move caret)
                window.scrollTo(0, currentScrollPosition + 120);
                break;

            default: return; // exit this handler for other keys
        } 
    });
}
