@*点击按钮页面刷新的时候 记住滚动条的位置*@

复制代码 代码如下:

<script type="text/javascript">

window.onbeforeunload = function () {

var scrollPos;

if (typeof window.pageYOffset != 'undefined') {

scrollPos = window.pageYOffset;

}

else if (typeof document.compatMode != 'undefined' &&

document.compatMode != 'BackCompat') {

scrollPos = document.documentElement.scrollTop;

}

else if (typeof document.body != 'undefined') {

scrollPos = document.body.scrollTop;

}

document.cookie = "scrollTop=" + scrollPos; //存储滚动条位置到cookies中

}

window.onload = function () {

if (document.cookie.match(/scrollTop=([^;]+)(;|$)/) != null) {

var arr = document.cookie.match(/scrollTop=([^;]+)(;|$)/); //cookies中不为空，则读取滚动条位置

document.documentElement.scrollTop = parseInt(arr[1]);

document.body.scrollTop = parseInt(arr[1]);

}

}

</script>
