How to include a HTML page into blogger posts ? (final)

I already undertook three attemps (attempt 1, attempt 2 and attempt 3) to include a Google Sheet into a blogger post without much succes. I almost surrendered but I got a new idea. I started from the proposal I found in "Insert HTML page into another HTML page" that basically proposed the following code:

<!--[if IE]>
   <object classid="clsid:25336920-03F9-11CF-8FD0-00AA00686F13" data="some.html">
      <p>backup content</p>
   </object>
<![endif]-->
<!--[if !IE]> <-->
   <object type="text/html" data="some.html">
      <p>backup content</p>
   </object>
<!--> <![endif]-->

The above code is very good for direct inclusion into a HTML page, but Blogger filters out the conditionals for selecting the code based upon the user agent. So it's not the solution we're seeking for. But then I got another idea. Maybe I could insert the above code using Javascript that IS allowed to be inserted in Bloggers HTML. In that way, it's possible to circumvent the restriction in Blogger HTML. I pasted the code into a HTMl-to-Javascript convertor. This gave me:

<script language="JavaScript" type="text/javascript">
<!--
function writeJS(){
var url = 'http://spreadsheets.google.com/pub?key=pzcvT0aLrnhuxklkh_C8AVA&output=html&gid=0&single=true&widget=true';

var str='';
str+='<!--[if IE]>';
str+='<object classid="clsid:25336920-03F9-11CF-8FD0-00AA00686F13" data="'+url+'">';
str+='<p>backup content<\/p>';
str+='<\/object>';
str+='<![endif]-->';
str+=' <!--[if !IE]> <-->';
str+='<object type="text\/html" data="'+url+'">';
str+='<p>backup content<\/p>';
str+='<\/object>';
str+='<!--> <![endif]-->';
document.write(str);
}
writeJS();
//-->
</script>


that renders as:

Above code reders nicely in Firefox and Safari but not in Interet Explorer 6.
Therefore I changed the code such that in IE an iframe is displayed and otherwise an object. The code was put into javascript:

<script language="javaScript" type="text/javascript"    src="http://lode.nachtergaele.googlepages.com/includeHTML3.js">
</script>


and on IE6 it renders to:


So finally, we start to view some light:


  1. First, include into blogger a Javascript:

    <script language="JavaScript" src="http://lode.nachtergaele.googlepages.com/includeHTML3.js" type="text/javascript" ></script>

  2. Put in the Javascript file the following Javascript code:

    <!--
    function writeJS(){
    var str='';
    str+='<!--[if IE]>';
    str+=' <iframe src="http://spreadsheets.google.com/pub?key=pzcvT0aLrnhuxklkh_C8AVA&output=html&gid=0&single=true&widget=true" width='550' height='370' frameborder='0'>';
    str+='<p>backup content</p>';
    str+='</iframe>';
    str+='<![endif]-->';
    str+='<!--[if !IE]> <-->';
    str+=' <object type="text/html" data="http://spreadsheets.google.com/pub?key=pzcvT0aLrnhuxklkh_C8AVA&output=html&gid=0&single=true&widget=true" width='550' height='370' frameborder='0'>';
    str+=' <p>backup content</p>';
    str+=' </object>';
    str+='<!--> <![endif]-->';
    document.write(str);
    }
    writeJS();
    //-->
  3. Alternatively, Javascript can detect the user agent as well. This leads to the following code:

    <!--
    function writeJS(){
    var str='';
    if (navigator.appName.indexOf("Microsoft") != -1) {
       str+=" <iframe       src='http://spreadsheets.google.com/pub?key=pzcvT0aLrnhuxklkh_C8AVA&output=html&gid=0&single=true&widget=true'       width='550' height='370' frameborder='0'>";
       str+='<p>backup content</p>';
       str+='</iframe>';
    } else {
       str+=" <object type='text/html'       data='http://spreadsheets.google.com/pub?key=pzcvT0aLrnhuxklkh_C8AVA&output=html&gid=0&single=true&widget=true'       width='550' height='370' frameborder='0'>";
       str+=' <p>backup content</p>';
       str+=' </object>';
    }
    document.write(str);
    }
    writeJS();
    //-->

  4. And that wil do the trick. The Javascript code generates HTML code that includes an Iframe if viewed by Internet Explorer and an object for other browsers. I agree that this is maybe a big detour just to able to include an object. And hopefully it shows up in the feed readers....

Sorry i didn't see this post earlier... The easiest method to include a google spreadsheet inline in a blog post is to use the publishing options of Google Spreadsheets itself...
STEP 1: On the "Publish" tab, publish the spreadsheet and then click the "More Publishing Options" link.
STEP 2: Select "HTML to Embed in a web page" as the format, and click "generate URL" which will actually generate a snippet of html code to embed in your web page.

If you can't use iFrames for some reason, than this won'e work well for you, but if you were using scripts in the previous examples, i assume iFrames are fine.

@jr Thx for your comment. As explained in
How to include a HTML page into blogger posts ? I'm aware of the standard and easiest way to include a Google Spreadsheet. Iframes render fine in most browsers. I was looking for a way to use object instead, as argued in The object tag - embed content in valid strict HTML -". That's all.

What if I have multiple speadsheets to display verically on one page and each spreadsheet varies in height from day to day? How can I display all of the spreadsheets in their entirety with just one scroll bar?
