將上一個頁面的div的scrolltop距離長度記錄在cookie中，然後通過js調整重新整理頁面時的長度記錄

<div id="x" style="height: 200px; overflow: scroll" onscroll="SetH(this)">
            <p>1</p>
            <p>1</p>
            <p>1</p>
            <p>1</p>
 

            <p>1</p>
            <p>1</p>
            <p>1</p>
            <p>1</p>

           <p>1</p>
           <p>1</p>
 </div>

<script>
        var _h = 0;
        function SetH(o) {
            _h = o.scrollTop
            SetCookie(
 
"a", _h)

        }
        window.onload = function () {
            document.getElementById("x").scrollTop = GetCookie("a");//頁面載入時設定scrolltop高度
        }
        function SetCookie(sName, sValue) {
            document.cookie = sName + "=" + escape(sValue) + "; ";
        }
        function GetCookie(sName) {

            
 
var aCookie = document.cookie.split("; ");
            for (var i = 0; i < aCookie.length; i++) {
                var aCrumb = aCookie[i].split("=");
                if (sName == aCrumb[0])
                    return unescape(aCrumb[1]);
            }

            return 0;
        }
    </script>
