        Caveats</p>
    <p>
        Browser's find gives result in both the page &amp; its preview<br>
        Async updates to the dom elements after minimap was created may not reflect in the
        preview.</p>

js代码：

$(document).ready(function () {

            var previewBody = $('body').minimap({
                heightRatio: 0.6,
                widthRatio: 0.1,
                offsetHeightRatio: 0.035,
                offsetWidthRatio: 0.065,
                position: "right",
                touch: true,
                smoothScroll: true,
                smoothScrollDelay: 200,
                onPreviewChange: function () { }
            });


        });
