效果html

把須要的css貼過去,而後把這段代碼放在須要顯示的頁面上jquery

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

控制顯示與隱藏的jsweb

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