            times++;
        }, 2000)

效果

把需要的css贴过去,然后把这段代码放在需要显示的页面上

 <div class="cssload-container">
        <div class="cssload-speeding-wheel">div>
    div>

控制显示与隐藏的js

   function showLoading() {
            $(".cssload-container").show();
        };
        function hideLoading() {
            $(".cssload-container").hide();
        };
