</head>
<body style="text-align:center">
    <h3>大图片加载从模糊到清晰</h3>
    <div class="mark" style='background-image:url(http://img.neweb.top/20181110.jpg);background-size:100%;
        filter: blur(4px);transition: all 0.7s;width: 800px;height: 450px;margin-left: 350px;'>
    </div>
    <script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
    <script type="text/javascript">
        // 为了看到效果加个延时
        setTimeout(function(){
            // 若图片URL失效请自行替换
            var imgUrl = 'http://img.neweb.top/20181110.jpg';
            var imgObject = new Image();

            imgObject.src = imgUrl;
            imgObject.onload = function(){
               $('.mark').css({
                    backgroundImage: 'url('+imgUrl+')',
                    filter: 'blur(0)'
                });
            }
        }, 1000)
