iframe嵌套frameset,实现整个iframe框架出现滚动条,怎么样随页面内容的高度全部展示出来?_html/css_WEB-ITnose

时间:2021-07-01 10:21:17 帮助过:33人阅读

我做的网站,是用frameset框架布局,分上中下,上面和下面框架部分的内容是固定的,中间框架内容是不同的,我想让整个框架共用一个滚动条,就用iframe嵌套frameset框架,我在iframe中设置了高度,页面内容不一样,高度也不一样了,有什么办法能让页面的内容全部展示出来?纠结两天了,很急,在线等!请各位大侠帮帮忙!


回复讨论(解决方案)

动态计算中间框架的高度,在《body onload里面加上上面、下面的高度,赋值给外面的iframe的style.height

怎么动态计算呀?请说明白一点吗?

h = document.documentElement?document.documentElement.offsetHeight:document.body.offsetHeight

这个是能子框架的页面的高度吗?

2个iframe能共用一个滚动条,好奇怪啊







<body>这个是我框架布局的页面, <br /> ------------------------------- <br /> <br /> <br /> <script language="javascript"> <br /> function iFrameHeight(iframeID){ <br /> var ifm= document.getElementById(iframeID); <br /> var subIfm = ifm.contentWindow.document.documentElement.scrollHeight; <br /> if(ifm != null && subIfm != null){ <br /> ifm.height = subIfm; <br /> } <br /> } <br /> </ script> <br /> <br /> </head> <br /> <br /> <body onmousewheel="top.document.body.scrollTop-=event.wheelDelta"> <br /> <br /> <iframe src="index.html" scrolling="no" name="frm" id="frm" width="100%" onload="iFrameHeight('frm')" /> <br /> 这个是我引入框架布局的页面 </p> <p class="sougouAnswer"> 这个是中间框架的,你再加上上、下的固定高度,然后+"px" </p> <p class="sougouAnswer"> 不是两个iframe啦 </p> <p class="sougouAnswer"> 我加了上下框架的高度,但是中间框架的页面内容不一样,高度也就不一样了,我获取不到中间页面的高度? </p> <p class="sougouAnswer"> 我加了上下框架的高度,但是中间框架的页面内容不一样,高度也就不一样了,我获取不到中间页面的高度? <br /> <br /> 不是告诉你动态计算的吗??? </p> <p class="sougouAnswer"> <p
