<div id="ctl00_ContentPlaceHolder1_editContent_designEditorArea" style="clear:both;padding-top:1px;">
<iframe id="ctl00_ContentPlaceHolder1_editContent_designEditor" style="padding: 0px; width:528px; height: 349px;" src="about:blank" class="ctl00_ContentPlaceHolder1_editContent_DesignBox"></iframe>
</div>
请问 怎么获取 里面iframe 的高度,不是style里面的哦,比如它本来高349px 我的图片超过了这个高度了,出现了滚动条,我要的是 滚动条和页面一起的高度~~~
<script>
function autoHeight(){
var imgDoc = frames['myImg'].document, h = imgDoc.body.scrollHeight?imgDoc.body.scrollHeight:imgDoc.documentElement.scrollHeight;
document.getElementById('tab').style.height=h+30+'px';
}
</script>
<div id="ctl00_ContentPlaceHolder1_editContent_designEditorArea" style="clear:both;padding-top:1px;">
<iframe onload="autoHeight()" name="myImg" id="ctl00_ContentPlaceHolder1_editContent_designEditor" style="padding: 0px; width:528px; height: 349px;" src="about:blank" class="ctl00_ContentPlaceHolder1_editContent_DesignBox"></iframe>
</div>
这里
document.getElementById('ctl00_ContentPlaceHolder1_editContent_designEditor').style.height=h+30+'px';
