js实现将div等滚动条(scrollbar)保持在最底部的方法.
很多时候我们要让程序的滚动条保持在底部,如聊天室.
下面将利用div+css+javascript实现保持滚动条在最底部.
代码如下,
|
<style type="text/css">
.cdiv{
background-color: white;
height: 100px;
width: 380px;
padding-left: 0;
overflow-y: scroll;
position: relative;
word-wrap: break-word;
overflow-x: auto;
text-align:left;
}
</style>
<div id="divmsg" class="cdiv"></div>
<input id="test" type="button" value="测试" />
<script type="text/javascript">
var test = document.getElementById("test");
var div = document.getElementById("divmsg");
test.onclick = function () {
div.innerHTML = div.innerHTML+"js实现将div等滚动条(scrollbar)保持在最底部的方法.--By <a href=\'http://www.shenlanit.com\' target=\'_blank\'>www.shenlanit.com[深蓝IT]</a>.<br/><br/>";
div.scrollTop = div.scrollHeight;
}
</script>

将代码保存成html文件即可查看效果.
