页面中利用JS定位到指定位置
2010-12-03 10:59 Peter Jin 阅读(3573) 评论(0) 编辑 收藏 举报当页面内容非常多时，拖动页面滚动条很不方便，这时就可以利用JS定位到指定位置：
<input type="button" value="▼" onclick="location.href='#page_botom';" />
<input type="button" value="▲" onclick="location.href='#page_top';" />
【例】
1 <html>
2 <HEAD>
3 <TITLE> New Document </TITLE>
4 <META NAME="Generator" CONTENT="EditPlus">
5 <META NAME="Author" CONTENT="">
6 <META NAME="Keywords" CONTENT="">
7 <META NAME="Description" CONTENT="">
8 </HEAD>
9
10 <BODY>
11 <a name="page_top" />
12 到后面去！
13 <input type="button" value="▼" onclick="location.href='#page_botom';" />
14 <TABLE border="1" align="center" width="750">
