The community has provided some wonderful tools recently to make early versions of IE do things that they were never meant to do. Like multi-column css selectors. Unfortunately I have not been able to find a java-script that I can load conditionally in IE lte 7 that converts multi-column layouts that use display: table-cell.
Does anyone know of such a script?
<div id="sidebar">
<ul id="main_nav">
<li><a href="about_us.php">ABOUT US</a></li>
</ul>
</div> <!--end of sidebar-->
<div id="content">
<div id="main_content">
<h1>Header</h1>
<p>Page Content</p>
</div> <!--end of main_content-->
<div class="aside_info">
<h2>Side Info</h2>
</div>
</div> <!--end of content-->
There are 3 columns #side_bar and #content are columns and within #content there is #main_content and #aside_info. This works great to create a 3 column layout on a page that has an #aside_info div but is two column other-wise.
if anyone knows a script that will convert this to tables for backward browsers I would appreciate it.
Thanks,
Daniel
It's pretty easy using jQuery:
$('<table><tr><td></td><td></td><td></td></tr></table>')
.find('td')
.eq(0)
.append( $('#sidebar') )
.end()
.eq(1)
.append( $('#main_content') )
.end()
.eq(2)
.append( $('.aside_info') )
.end()
.end()
.appendTo( $('#content') );
Hope this helps!
I worked up a solution to this problem, and when I came back I saw that jimbojw had put together a much more elegant-looking solution. I'm voting his up because its simplicity is very appealing (note to self: learn more jQuery !). However, I'm posting my solution here anyway in case you can't use jQuery, don't know how to test for IE7, or for some other reason need a different solution:
<div id="sidebar">
<ul id="main_nav">
<li><a href="about_us.php">ABOUT US</a></li>
</ul>
</div> <!--end of sidebar-->
<div id="content">
<div id="main_content">
<h1>Header</h1>
<p>Page Content</p>
</div> <!--end of main_content-->
<div class="aside_info">
<h2>Side Info</h2>
</div>
</div> <!--end of content-->
<script type="text/javascript">
// Test for IE version
var ieversion = 0;
if (/MSIE (\d+\.\d+);/.test(navigator.userAgent)){ // IE test adapted from http://www.javascriptkit.com/javatutors/navigator.shtml
ieversion = new Number(RegExp.$1)
}
if(ieversion > 0 && ieversion < 8)
{
// Find the existing DIV elements
var sidebarDiv = document.getElementById("sidebar");
var mainContentDiv = document.getElementById("main_content");
var contentDiv = document.getElementById("content");
// Create the structure of the table that will replace them
var tableElement = document.createElement("table");
var tbodyElement = document.createElement("tbody");
var trElement = document.createElement("tr");
var sidebarTd = document.createElement("td");
sidebarTd.id = "sidebar";
var mainContentTd = document.createElement("td");
mainContentTd.id = "main_content";
var asideInfoTd = document.createElement("td");
// Clone the DIVs' child nodes and add the clones to the appropriate TDs. Then add the TDs to the TR.
for(var i=0;i<sidebarDiv.childNodes.length;i++)
{
sidebarTd.appendChild(sidebarDiv.childNodes[i].cloneNode(true));
}
trElement.appendChild(sidebarTd);
for(var i=0;i<mainContentDiv.childNodes.length;i++)
{
mainContentTd.appendChild(mainContentDiv.childNodes[i].cloneNode(true));
}
trElement.appendChild(mainContentTd);
mainContentDiv.parentNode.removeChild(mainContentDiv);
var contentChildDivs = contentDiv.getElementsByTagName("div");
for(var i=0;i<contentChildDivs.length;i++)
{
if(contentChildDivs[i].className.indexOf("aside_info") > -1)
{
asideInfoTd.appendChild(contentChildDivs[i].cloneNode(true));
}
}
// We only add the aside info if there were some (sometimes there aren't)
if(asideInfoTd.childNodes.length > 0)
{
trElement.appendChild(asideInfoTd);
}
// Finish putting the table together
tbodyElement.appendChild(trElement);
tableElement.appendChild(tbodyElement);
// Remove the existing content div and then replace the sidebar with the new table that contains all 2 or 3 columns.
contentDiv.parentNode.removeChild(contentDiv);
sidebarDiv.parentNode.replaceChild(tableElement, sidebarDiv);
}
