Question

你好我的问题是当汽车进入屏幕时如何停止车轮转动，每当有任何车进入屏幕时请停止车轮转动。

我的代码：

c#

$(document).ready(function () {
    $('.wheelEleContainer .slectWheel').click(function (e) {
        e.preventDefault();
        var getImgWheel = $(this).find('img').attr('src');
        $('.car .wheelInCar').css('background-image',
          'url(' + getImgWheel + ')'
        );
    });
    var running = false;
    $('.car-model').click(function (e) {
        e.preventDefault();
        var index = $(this).data("index");

        var $pre = $('.car-image.current');
        var $dom = $('.car-image[data-car-index="' + index + '"]');
        if ($dom.hasClass("current") || running) {
            return;
        }
        var current_pull = parseInt($('.current').css('transform').split(',')[5]);
        
        running = true;
        $dom.addClass('current');
        $pre.addClass('left').removeClass('current');
        setTimeout(function () {
            if (current_pull == 0) {
                $('.wheelInCar').css('animation-play-state', 'paused');
            }
            else {
                $('.wheelInCar').css('animation-play-state', 'running');
            }
            $pre.addClass('no-transition');
            $pre.removeClass('left');
            setTimeout(function () {
                $pre.removeClass('no-transition');
                running = false;
            }, 100);
        }, 2100);

    });
})

Answer 1

试用此代码

public class Fragment2 extends Fragment {


    public Fragment2() {
        // Required empty public constructor
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_2, container, false);
    }

    public void fragment2refresh(){
        // TODO: this to be call when refresh on MainActivity and also fragment_2 is visible 
    }

}

$(document).ready(function () {
	run();
    $('.wheelEleContainer .slectWheel').click(function (e) {
        e.preventDefault();
        var getImgWheel = $(this).find('img').attr('src');
        $('.car .wheelInCar').css('background-image',
          'url(' + getImgWheel + ')'
        );
    });

    var running = false;
    $('.car-model').click(function (e) {
        e.preventDefault();
        var index = $(this).data("index");
        var $pre = $('.car-image.current');
        var $dom = $('.car-image[data-car-index="' + index + '"]');
        if ($dom.hasClass("current") || running) {
            return; 
        }
        running = true;

Answer 2

CSS的一个班轮：

.car .car-image .wheelInCar {
    width: 99px;
    height: 100px;
    position: absolute;
    background-repeat: no-repeat;
    background-position: center center;
    -webkit-animation: wheelRotating 2s linear infinite;
    -moz-animation: wheelRotating 2s linear infinite;
    -ms-animation: wheelRotating 2s linear infinite;
    -o-animation: wheelRotating 2s linear infinite;
    animation: wheelRotating 2s linear infinite;
    animation-play-state: paused; /* Not exactly one line if you want to make compatible with prefixes */
}

添加类时停止CSS动画
