How to add Archive Calendar to blogger

I have been looking for a Calendar that can be link with my blog post archive, which when I select a month, it will display all the posts for that month, and when I choose a date, it will display the posts for that date. And of course when I click on the displayed Post Title, it will open that post.


phydeaux have a very nice archive calendar, I like it very much, but unfortunately it does not work in my blog. so I googled another one by purplemoggy, this time it works nicely.


I have make a make some amendment to purplemoggy orignal code. Below is the version that works on my blog.



<!-- yahoo archieve calendar start -->

<script src='http://yui.yahooapis.com/2.2.0/build/calendar/calendar-min.js' type='text/javascript'/>
<link href='http://freewarehouse.googlepages.com/yahoo-calendar.css' rel='stylesheet' type='text/css'/>

1. Log in to blogger, go to {template}->{edit html}, look for </head>, paste the following code above </head>


2. Next go to {Layout}->{Page Element}->{Add Gadget}, add a new {HTML/javascript} element and paste the following code inside.



<div id="cal1wrapper">

<div id="cal1select">

<select id="cal1monthselect" name="cal1monthselect">
<option value="0"/>January
<option value="1"/>February
<option value="2"/>March
<option value="3"/>April
<option value="4"/>May
<option value="5"/>June
<option value="6"/>July
<option value="7"/>August
<option value="8"/>September
<option value="9"/>October
<option value="10"/>November
<option value="11"/>December
</select>
<select id="cal1yearselect" name="cal1yearselect">
<option value="1995"/>1995
<option value="1996"/>1996
<option value="1997"/>1997
<option value="1998"/>1998
<option value="1999"/>1999

<option value="2018"/>2018
<option value="2019"/>2019
</select>
<input id="cal1dateselect" value="-->" type="button"/>

</div>

<div id="cal1Container"><img style="vertical-align:middle;" src="http://img239.imageshack.us/img239/9057/40lf8.gif"/> Loading...</div>
<div style="clear:both;"></div>

<div id="calbackloadimg">
<div id="cal1loadimg" style="display:none;"><img style="vertical-align:middle;" src="http://img239.imageshack.us/img239/9057/40lf8.gif"/> Loading...</div>
<div id="cal1Titles"></div>
</div>

</div>

3. Finally, In the 1st code-box above, you'll need to edit the following 2 variables


_yourBlogUrl needs to be changed to your blog URL (don't add the trailing slash)


http://yaplc.blogspot.com <-- CORRECT


http://yaplc.blogspot.com/ <-- WRONG
