下面的例子窗口是否在一个框架中,如果是,则跳出框架:
</>code
- <html>
- <head>
- <script type="text/javascript">
- function breakout()
- {
- if (window.top!=
window.self
)- {
- window.top.location="tryjs_breakout.htm"
- }
- }
- </script>
- </head>
- <body>
- <input type="button" onclick="breakout()"
- value="Break out of frame!">
- </body>
- </html>
