How can I turn this click event function into one that is called automatically when the div loads?

I perform a function which loads content into a div. I am using innerHTML, I GET a php file, which updates the innerHTML of the div with the php file's content.
This div contains another div inside it with the class and id of "tweet". This div is updated with actual tweets of a specific hashtag, passed to the function through a $variable
It works fine when it is simply an onclick event, such as this:
<p>activity</p>
<div class="tweet" id="tweet"></div>
However, what I want to do is have it automatically load tweet('') once the "tweet" div has loaded.
The tweet(hashtag) function is:
function tweet(hashtag) { $("#tweet").load('tweet.php?hashtag='+hashtag); }
which loads a php file that calls the jquery tweet function.
jQuery(function($){
$(".tweet").tweet({
avatar_size: 32,
count: 3,
query: "<?echo $hashtag;?>",
loading_text: "loading tweets...",
refresh_interval: 3
});
});
Based on the hashtag passed, it shows 3 tweets.
The hashtag is called when the page is loaded, as a session variable.
It all works fine when I click the link. What do I need to do to have this load automatically. so that I don't need to click the link? I have tried a number of autorefresh options but couldn't quite get it. I would really appreciate assistance.
I know that, if this was just a regular page being loaded, I can simply use $(document).ready and call the jquery function. However, due to the way the div is populated with the new php file contents, it doesn't work. I have tried a few times using autorefresh intervals, window onload, etc. They don't seem to work either.

There are two ways to try this:
Run the code somehow from the function which you call to load the div. (Guaranteed to work. You may even put together some kind of plugin concept. "eval" may be useful.)
Add a tag after the div. If things work as you hope, that code will execute immediately.

A mysterious situation with jQuery or am I blind?

i have a jQuery code and the html code on my page. The code loads two php files on two DIVs, based on the value of a drop down list. The code is working great, loading pic and everything. However I have a small problem.
When I place the second div ( artistdetails ) inside of a seperated div from the first div, the loading pic does not appears on the second but only in the first. Content is appeared correctly though.
As I saw in firebug, the class is loading fine. I even changed the picture to something bigger but nothing was there. ( I mean the pic is not hidden somewhere).
I made a lot of experiment, I set the ID to the float:left div but nothing happens. I really need to have them in a separated DIV. Is that possible?

I would start looking at the final generated code (which you might post here or on pastebin.com with a link).
Sounds to me like something in the php forms is probably not generating valid html. For example, an unclosed entity.

It must work, i guess, if the class is added to <div id="artistdetails"></div>
Still try something like this
$('#artistdetails').empty()
.addClass('loading')
.load('forms/' + val + 'b.php',
function(){
setTimeout(
function(){ $('#artistdetails').removeClass('loading') },
2000);
});

javascript Refresh Div

I am using this code to refresh the data inside of the div:
<script>
$(function() {
$("#refresh").click(function() {
$("#new").load("/new.php")
})
})
</script>
Except it loads the who page inside of the div, instead of just the information that is inside of the div.
How do I make it refresh only the data that is inside of the div? Is there a way of doing it other than putting the information for that div in a seperate page?

If you mean that new.php is a script that returns the entire page, the answer is no.
You have to send just the html fragment you need for refreshing the div.
You can always get the result from new.php, take the good part and discard the rest but it is inefficent.

You can load page fragments with 'load'. Say the information you need is inside a div called "#info" on new.php, change the load line to this:
$("#new").load("/new.php #info")

If you were refreshing data from the server you have to reload the whole page/frame (you could request the client to cache images, CSS, etc.) or use Ajax.

Addthis javascript button/widget adding space to top of webpage

If you view this page http://www.herkimer.edu/news/view/community_members_complete_jointly_offered_machine_operator_training_progra/
You'll notice a green bar (screen-shot: http://grab.by/1msh) at the very top. It has something to do w/ the addthis widget you'll see underneath the h1 title.
If you reload the page a couple times, the bar goes away, probably because the script is cached and does not delay, resulting in that extra space at top.
Do you know what I could do to resolve this? Any help is appreciated.

I'm assuming that you don't want the DIV to display. You could add some CSS to the page to hide it. It has id atffc (and contains a Flash object, but I don't know that it needs to be visible).
#atffc { display: none; }

I think in addition to just hiding your extra div you may want to move the elements to the bottom of your page so they are evaluated after the add_this anchor tag () is created and ready. That would help with potential timing issues to make sure the element is loaded and ready before their code starts to try to manipulate it.

I had the same problem and I downloaded their new code
http://www.addthis.com/web-button-select
I selected "no analytics" and I think they now strip out the flash part when using no analytics. I haven't had the problem again the last time I checked but I'll need more time to confirm this.
You might want to try to do the same

A bit late, but try adding this code AFTER the AddThis button code:
<script type="text/javascript">
var addthis_config = {
data_use_flash: false
}
</script>

Removing appended html using jQuery?

Using jquery, I currently append html to a div on a click event. The following code allows me to fade in only the appended portion of the div:
var html = "..";
$('<div></div>').appendTo("#id").hide().append(html).fadeIn('slow');
This portion works perfectly. But how can I later remove (fade out) only the appended portion? I tried hacking this by storing the html prior to the appending, and then simply hiding everything and showing the stored html. But this does not work well when the same procedure is reused for several divs on the same page (and this seems like poor implementation). Is there a good way to do this?
Just to give an idea of why I need this: Think of a blog type page where for every article on the page there are several comments with only x amount showing by default: the click event fetches the remaining comments and displays them, and then toggling the button again removes the appended comments and sends it back to the original state.

empty() is always an option
jQuery('#main').empty();

Give a look at the empty() function.
It might better solve the problem. Here's the link http://api.jquery.com/empty/

I'd just set and clear the html with '.html()' ...
-- edit
to be more clear, have an area layed out specifically for the addition of these comments:
<div id='commentarea1'></div>
etc.

Try:
var html = "..";
$('<div></div>').appendTo("#id").hide().append(html).fadeIn('slow').addClass('appended');
then later
$('#id .appended').fadeOut('slow'); // or whatever you want to do.

It is not that clear from the question but say you show 5 comments by default and then show x more comments. To get back to the original 5 comment default state you can remove all comments with an index greater than 4 (zero based).
The following assumes each comment goes inside its own div that has a class comment.
$('#id>div.comment:gt(4)').remove();
