本文实例讲述了JS获取iframe中marginHeight和marginWidth属性的方法。分享给大家供大家参考。具体如下：
<!DOCTYPE html>
<html>
<body>
<iframe id="myframe" src="demo_iframe.htm"
marginheight="50" marginwidth="50">
<p>Your browser does not support iframes.</p>
</iframe>
<br><br>
<p>The value of the marginheight attribute and marginwidth are:
<script>
document.write(document.getElementById("myframe").marginHeight);
document.write(document.getElementById("myframe").marginWidth);
</script>
<p>
</body>
</html>希望本文所述对大家的javascript程序设计有所帮助。
