篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了自己写的_top_parent以及对iframe和frameset的理解相关的知识,希望对你有一定的参考价值。
iframe可以写在<body>标签里,如<body><iframe src="xxx" name="xxx" style="width:100%;height:500px;"/></body> iframe标签要成对,不然后面的标签不起作用
frameset不可以写在<body>标签里,如:
<html xmlns="http://www.w3.org/1999/xhtml" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> </head> <frameset rows="50%,25%,*"> <frame name="frameset_target" src="./HelloWorld.html" noresize="noresize"/> <frame src="/hello.java"/> <frame src="/hello.java"/> </frameset> </html>
-----------------------------------------------------------------------------------------------iframe
<h5>iframe__frameset</h5> <p><a href="V1.jpg" target="iframe_target">iframe</a></p> <p><a href="V1.jpg" target="frameset_target">frameset</a></p> <iframe src="/hello.java" name="iframe_target" style="width:100%;height:500px;"/>
-----------------------------------------------------------------------------------------------frameset
注:必须先将frameset所在页面打开,然后,再点击里面的超链接到frame里的标签,(frameset的子标签是frame,不是iframe)
