Hi Rory, On page 29 of the 4 days on rails book http://www.rails4days.pwp.blueyonder.co.uk/Rails4Days.pdf There is the code to implement this feature. Hope this helps Dan On 10/14/05, Rory Hansen <roryhansen-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> > Hi group, > Wondering if anyone has written any clever rhtml for implementing zebra > striped tables. > I bet you someone here has a 1-line solution. > Rory > > _______________________________________________ > Rails mailing list > Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org > http://lists.rubyonrails.org/mailman/listinfo/rails > > >_______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails
I would strongly advise against striping with backend code. It has no reason
to be mucking around in styles like so.
The best solution is to use a pure CSS method, unfortunately IE6 won''t
support this. No worries, a little bit of javascript ingenuity will fix
this. Here''s a little script I whipped up a while ago:
// Zebra Tables, by class
var stripe = function() {
var tables = document.getElementsByTagName("table");
for(var x=0;x!=tables.length;x++){
var table = tables[x];
if (!table || !HasClass(table, ''alternate'') ) { return; }
var trs = tables[x].getElementsByTagName("tr");
even = false;
for (var i = 0; i < trs.length; i++) {
if (even)
AddClass(trs[i], ''even'')
even = !even;
}
}
}
Basically, if your table has a class of ''alternate'' it will
add a
class of ''even'' to all even tr''s in that table.
Note: this assumes
you have a HasClass function. Here''s one for example:
// Class Detection

function KillClass(obj,cName){ return obj &&
(obj.className=obj.className.replace(new
RegExp("^"+cName+"\\b\\s*|\\s*\\b"+cName+"\\b",''g''),''''));
}
//***Returns true if the object has the class assigned, false otherwise.
function HasClass(obj,cName){ return (!obj ||
!obj.className)?false:(new
RegExp("\\b"+cName+"\\b")).test(obj.className) }
window.onload = stripe;

Thanks for the examples guys. I had implemented it similar to Ezra (as I often do in other languages) but I thought there might be a better way with more joy and less code. :) I''ll dig through some of the responses and see what''s been suggested. I also did see the A List Apart article on Zebra Striping (which is where I stole the name for this post) but, unlike some of the views expressed here, I am not interested in using javascript to implement it.

Is there any particular reason for it? I can tell you from a real-life usage perspective, putting backend in control of the table striping causes problems. Perhaps not today, perhaps not in a couple of days - but with regular maintainence it turns out to be a bad idea. Javascript is perfectly suited for this task - enhancing the functionality of a web page. Also, if you''re talking about joy and less code, I''m pretty sure this wins out: class="alternate" Dave>> That is where my script originated, although mine deals with classes, while theirs deals with ID''s. You can only have one ID per page, while you can have many classes per page. Mine actually is a lot more flexible. I''m not sure why they went with ID''s anyway.

This is css bloat and anyone suggesting it should be ashamed of themselves ;-) Everyone repeat after me "there is no need to add excess attributes to the markup for the default state"! The css for a zebra-striped table looks like this: tr { /* Styles for evens */ } tr.alternate { /* Styles for odds */ } And if it worries you to style every row in the site the same, then style them contextually: table#foo tr { /* Styles for evens */ } table#foo tr.alternate { /* Styles for odds */ } I''m a rank Ruby/Rails newbie, but I think I''ve made the appropriate modification to the other Christopher''s post - though I don''t know if I''ve escaped the quotes correctly: <tr<%= index.even? ?

You say this, but you don''t say what problems. I don''t think there is anything particularly bad about using a bit of Ruby logic to determine what class to apply to a row. Ideally though, the functionality should be wrapped up as a view helper method for clarity. I can understand it possibly being harder to maintain if the table is static, but if its dynamically generated from a recordset, then I can''t see what can go wrong. Here is an example helper: http://www.bigbold.com/snippets/posts/show/411 Both Ruby and JS methods have their pros/cons.

Personally I dont think there is much in it.... either use ruby or javascript to stripe tables. The main advantage of using javascript is that you can still add classes to your your table rows to indicate say that a row is selected or what ever because the javascript uses style instead of class. You cant have two classes but you can have style and class. The disadvantage is that the browser needs to js enabled. Kris.
Deidre, my main point was that whatever way you implement this (Ruby-wise), it should be wrapped up in a view helper.

It''s a bit of a divergence from the original topic, but you *can* have two classes. <div class=''odd selected''>blah</div> is perfectly valid markup, and gives the div both the ''odd'' class and the ''selected'' class. See http://www.w3.org/TR/html4/struct/global.html#h-7.5.2, and I quote: "class = cdata-list [CS] This attribute assigns a class name or set of class names to an element. Any number of elements may be assigned the same class name or names. Multiple class names must be separated by white space characters." -- Alex

As a rails noob I''m not sure exactly what you mean. Thanks -Luke
The problem, I believe, is when you start mixing in javascript sorting at the client. Then your table looks pants when you move from (for example) order_by_id to order_by_date with some funky DOM management. Striping with javascript ensures its always appropriately striped.
