When I change the first checkbox, I want to change the var theSame, but it seems it doesn't change in if(theSame == 1);
but it changes in alert("b"+theSame). How to handle this?

This is not really a question of scope, but more of asynchrony. Let's step through your code:
$(document).ready(function(){
// Define function-scope variable `theSame`, assign it a value of `1`
var theSame = 1;
// Bind a `change` event handler to an element, this function will run later!
$("input[name='thesame']").change(function(){
theSame = +this.checked;
alert("a"+theSame);
});
// At this point, `theSame` has not changed from its original value!
if(theSame == 1){
$(".check_list input").change(function(){
// Here, however, `theSame` may have had its value changed
alert("b"+theSame);
});
}
});
So, as you can see, when the if statement runs it will always have a value of 1, because the value isn't changed until later, after this code has already been executed.
If you move the if statement to inside the event handler, you'll see different results:
$(".check_list input").change(function(){
if(theSame){
alert("b"+theSame);
}
});
Here, you'll only see the alert if theSame is 1.

I have two input fields and i use a keypress function to enter only specific chars in the second input. I can enter until the chars from the first field finished. So, when i finished typing i want to appear an alert message like:
alert(ok finish!);
it is possible?
With JQuery you could do this:
$('#textfield2').bind('blur',function() {
alert('I guess i finished typing cause I left the field!?');
});
I have this code:

function markPercentages(){
var checked = $(':checked');
var percentage = Math.round((1 / checked.length) * 100);
checked.siblings('.percentage').html(percentage);
$('input[type=checkbox]').not(checked).siblings('.percentage').html('0');
}
</script>
</head>

Value<br /><input type=text name=cost onChange="addDecimalPoints(this.id)" id=cost /><br />
<input type=submit value="Save" />
</form>
</body>
</html>
It shows a percentage right next to the building (Susilos) of the cost that it's adding. In simplest terms, if one is checked it shows 100%, if two are checked it shows 50% on the first and 50% on the second and so on.
It works fine in Chrome but in Firefox when I check just one, it shows 50% on that, like there are checked two. When I check two it shows 33% on those, like I checked three of them. Why this happen and how I should fix this?
Anyway , deleting a part of the code that's beyond that code makes that works also:

HTML:
<div>
<input type='checkbox' />Susilo 2A-13 (<span class='percentage'>0</span>%)
</div>
<div>
<input type='checkbox' />Susilo 2A-14 (<span class='percentage'>0</span>%)

JS:
$(document).ready(function() {
$('input').click(function(){
markPercentages();
});
function markPercentages(){
var checked = $(':checked');
var percentage = Math.round((1 / checked.length) * 100);
checked.siblings('.percentage').html(percentage);
$('input[type=checkbox]').not(checked).siblings('.percentage').html('0');
}
});
If you have more inputs on the page just give your checkboxes a class like 'markbox' and change 'input' to '.markbox' in your JS
what about use like this one
$(function(){
$('input[type=checkbox').click(function(){
var checked = $('input[type=checkbox]').attr('checked');
var percentage = Math.round((1 / checked.length) * 100);
checked.siblings('.percentage').html(percentage);
$('input[type=checkbox]').not(checked).siblings('.percentage').html('0');
});
});
Try this code. I basically rewrote all of your logic:
<html>
<head>
<script type='text/javascript' src='http://code.jquery.com/jquery-1.7.1.min.js'></script>
<script type="text/javascript">
$(document).ready(function() {
$(':checkbox').change(function() {
var num_checked = $(':checkbox:checked').length;
if (num_checked == 0) {
$(':checkbox').each(function() {
$(this).siblings('.percentage:eq(0)').text('0');
});
return;
}
var percentage = Math.round(100 / num_checked);
$(':checkbox').each(function() {
if ($(this).is(':checked')) {
$(this).siblings('.percentage:eq(0)').text(percentage);
} else {
$(this).siblings('.percentage:eq(0)').text('0');
}
});
});
});
</script>
</head>

<div>
<input type='checkbox'/>Susilo 2A-13 (<span class='percentage'>0</span>%)

Here's the edited code, but it still doesn't work:

Inside your <script></script> tag is where your JavaScript goes (although we prefer putting it in a separate file, so that no JavaScript lives on the HTML page itself).
Inside that, you have a call to $(document).ready(), which passes a function() { ... }. Inside that function is all the code that will be executed when your document has loaded.
Inside that function you have a call to $('#site').focus() which itself provides a function — this time one that will be called whenever the #site element gains focus. And presumably that's where you want to change the cursor position.
So, taking the setCursor function from Set cursor at a length of 14 onfocus of a textbox you can put that anywhere in your <script></script> and then inside that innermost function of yours you can write:
if( this.value == this.defaultValue ) {
$(this).val("http://");
var node = $(this).get(0);
setCursor(node,node.value.length);
}
I think I found the error in your setCursor method. The moveStart and moveEnd methods expect two arguments, the first being the unit it should use. Also, the end position appears to be relative to the start position. So I think instead of
textRange.moveEnd(pos);
textRange.moveStart(pos);
you want
textRange.moveStart('character', pos);
textRange.moveEnd('character', 0);
See: http://msdn.microsoft.com/en-us/library/ie/ms536623(v=vs.85).aspx
Oh, this one's easier done than said!
<script>
function setCursorInputPosition(e, pos) {
e.setSelectionRange(pos, pos);
}
</script>
<input onfocus="setCursorInputPosition(this, this.value.length);">
I must be missing something obvious here... I can't get .change() to fire on radio buttons? I have the code below live here!

You must put the code inside the dom-ready event...
$(document).ready(function(){
// Your code here
});
or else the script gets executed before the HTML-elements have been loaded. Thus, no radioboxes exist.
Your
$("output").text("a changed");
should also be
$("#output").text("a changed");
because it is an id you are matching against.
