10 Ruby on Rails Plugins You Should Be Using

Media72: 10 Ruby on Rails Plugins You Should Be Using

jQuery: Cookie Plugin

I've become a big fan of jQuery and have contributed two small plugins myself, so when it came time to switch to a library for cookie manipulation with Javascript (time to replace all that nasty inline JS code) my first choice was jQuery.

Not to be disappointed, I found that Klaus Hartl has written a very slim and useful Cookie Plugin for jQuery.

Here's a small page test using the jQuery Cookie plugin:

<title>jquery cookie</title>

<script type="text/javascript" src="jquery-1.2.1.min.js"></script>
<script type="text/javascript" src="jquery.cookie.js"></script>

<script type="text/javascript">

$(function($) {

function displayMessage(msg) {
$('#message').html(msg).css({color: 'green'});

displayMessage('jQuery cookie plugin test');

$('#setSessionCookie').click(function() {
$.cookie('test', 'Hmmm, cookie');
displayMessage("Cookie 'test' has been set.");

$('#setCookie').click(function() {
$.cookie('test', 'Hmmm, cookie', { expires: 7 });
displayMessage("Cookie 'test' has been set and will expire in 7 days.");

$('#getCookie').click(function() {
displayMessage("The value of the cookie named 'test' is: " + $.cookie('test'));

$('#deleteCookie').click(function() {
$.cookie('test', null);
displayMessage("Cookie 'test' has been deleted.");

$('#testCookiesEnabled').click(function() {
$.cookie('testcookiesenabled', null);
$.cookie('testcookiesenabled', 'enabled');
if ($.cookie('testcookiesenabled')) {
displayMessage("Cookie: "+ $.cookie('testcookiesenabled'));
} else {
displayMessage("Cookies disabled");
$.cookie('testcookiesenabled', null);





<p><span id="message" style="forecolor: red;"></span>

<p><input type="button" id="testCookiesEnabled" value="Cookies enabled?"/></p>

<p><input type="button" id="setSessionCookie" value="Set session cookie"/></p>

<p><input type="button" id="setCookie" value="Set cookie expires in 7 days"/></p>

<p><input type="button" id="getCookie" value="Show cookie value"/></p>

<p><input type="button" id="deleteCookie" value="Delete the cookie"/></p>

ASP.NET GridView - Header always bold

GridView uses a table and creates a <th> tag for the header, which will bold all the text generated by the GridView. Here's a simple solution:

Set a style:

.GridViewHeaderStyle th {
font-weight: normal;

And apply it to your GridView:

<asp:GridView ID="grdSomeGrid" runat="server" CssClass="GridViewHeaderStyle">

ASP.NET GridView "ShowFooter"

Sometimes it's the small things that get you...

Uh, not that it ever happened to me, but in case you can't get your GridView template footer to show up...don't forget 'ShowFoooter="true"' :)

<asp:GridView ID="grdListings" runat="server" AutoGenerateColumns="false" BorderWidth="0"
AllowPaging="true" PageSize="5" OnPageIndexChanging="grdListings_PageIndexChanging" ShowFooter="true">

Install Ruby without openssl

When installing Ruby on an old machine, I got this error:

ruby make[1]: *** [ossl_ssl.o] Error 1

Other than installing openssl, which wasn't option, install ruby without openssl:

$ ./configure prefix=/home/doug/bin/ruby --without-openssl
