jQuery frameset 对象的操作及scrollTop
<frameset rows="*" cols="195,*" frameborder="no" border="0" framespacing="0">
<frameset rows="61,*,48" cols="*" frameborder="no" border="0" framespacing="0">
<frame src="tree_top.html" name="leftFrame" scrolling="no" noresize="noresize" id="leftFrame" title="leftFrame" />
<frame src="treeMenu.jsp" name="treeMenuFrame" scrolling="auto" id="treeMenuFrame" title="treeMenuFrame" marginheight="0" marginwidth="0"/>
<frame src="login_bottom.jsp" name="loginFrame" scrolling="no" id="loginFrame" title="loginFrame" />
</frameset>
<frame src="content.jsp" name="mainFrame" id="mainFrame" title="mainFrame" />
</frameset>
login_bottom.jsp要操作content.jsp页面中的id为"login"的对象:
jQuery(window.parent.parent.frames["mainFrame"].document).find('div[@id="cover"]')
获取整个页面的高度包括滚动后的高度
jQuery(window.document).height()
滚动的时候scrollTop一直为0的解决方法:
写法有误不是 document.body.scrollTop 而是 document.documentElement.scrollTop
<head> <title>51windows.Net </title> <meta http-equiv="Content-Type" content="text/html; charset=gb2312"> <style type="text/css"> </style> </head> <body> <SCRIPT LANGUAGE="JavaScript"> var s = ""; s += "\r\n网页可见区域宽："+ document.body.clientWidth; s += "\r\n网页可见区域高："+ document.body.clientHeight; s += "\r\n网页可见区域宽："+ document.body.offsetWidth +" (包括边线的宽)"; s += "\r\n网页可见区域高："+ document.body.offsetHeight +" (包括边线的宽)"; s += "\r\n网页正文全文宽："+ document.body.scrollWidth; s += "\r\n网页正文全文高："+ document.body.scrollHeight; s += "\r\n网页被卷去的高："+ document.body.scrollTop; s += "\r\n网页被卷去的左："+ document.body.scrollLeft; s += "\r\n网页正文部分上："+ window.screenTop; s += "\r\n网页正文部分左："+ window.screenLeft; s += "\r\n屏幕分辨率的高："+ window.screen.height; s += "\r\n屏幕分辨率的宽："+ window.screen.width; s += "\r\n屏幕可用工作区高度："+ window.screen.availHeight; s += "\r\n屏幕可用工作区宽度："+ window.screen.availWidth; alert(s); </SCRIPT> </body> </html> |
