jQuery Forum

I can't understand this syntax for defining variables, I mean what the $ sign is doing when declaring a variable:

1. $('#quick_reply').submit(function(event) {
2.     var $form = $( this ),
3.     message = $form.find( 'textarea[name="message"]' ).val(),
4.     url = $form.attr( 'action' );
5. .....

I am specifically talking about line2

I have to select the href of the highlighted a tag but am unable to do so using:

1. var a = $('h1.page-title').next('a').attr('href');
2. alert("This is: " + a + "");

I know there are many tutorials out there & have searched this forum as well; but my case is light different...
@ I can't edit templates, so everything to be done via js insertion/modification
This is the original html:  [not complete]

1. <form action="/post" method="post" name="post"  id="quick_reply">...
2. ....<input type="submit" name="post" class="button2" value="Send">...

the above is an editor for phpbb3, when we post a message we are directed to  http://example.com/post where there is a confirmation of message being posted then we are redirected . I want to skip that

so I tried with this a mixture of js & jquery
first I inserted this html before or after something

1. <iframe name="cgiFrame" id="cgiFrame" onload="skipper()" src="" style="display:none; width:0px; height:0px"></iframe>

something like this

1. $('#page-footer').before('<iframe name=\"cgiFrame\" id=\"cgiFrame\" onload=\"skipper()\" src=\"\" style=\"display:none; width:0px; height:0pxl\"><\/iframe>');

then I inserted an onclick attr to the send button
original html snippet

1. onclick="this.form.target='cgiFrame';"

then its insertion

1. $('.button2 [value="Send"]').attr('onclick', 'this.form.target=\'cgiFrame\';');

the I defined the required function

1. function skipper() {
2.  var CurrentUrl = document.getElementById('cgiFrame').contentWindow.location.href;
3.  if (CurrentUrl=='http://xxxxx/post'){
4.  window.location.reload();
5.  } else {
6.  return false;
7.  }
8.  }

done, now we are ready to experiment

I write something in the editor & then press send
1] @lowinternet speed: script worksconfirmation page skipped
2] @highinternet speed: script don't  works  confirmation page appears


any ideas/ any other approach, I will love to read any resources on this issue.

I am trying to remove the online class ONLY for administration which has a unique url namaley /u1. The idea is to scan all the divs containing TWO classes namely post (users reply) & online (users currently logged in). Then check whether this reply or div is from administration, then remove the online class thereby removing the online picture that is floating left.
Any ideas would be appreciated

Background: You enter some text in message editor textbox; press send; page (& not popup) appears stating 'Message successfully recorded...return to message'
Send button HTML

1. <input type="submit" value="Send" class="button2" name="post">
   

Limitations: Cannot edit template/html ...had to be done via javascript/jquery

Objective: to replace Send button with a custom one such as one you press it (after message is entered) you be redirected back to your current page(URL) & 'Message successfully recorded...return to message' page is thus skipped.

Abstract ideas:
1] Get the href of current page via a function

1. function threadurl(href) {
2.     $.get(href, function() {
3.         window.location.reload();
4.     });
5. }

2] replace 'Send' button with custom one (with class: button2...& other attributes) & somehow add

1. <a onclick="threadurl.....

How do I get href links from classes & append/prepend them to some element.
My attempts...& many other I can't mention
