On page load, if URL hash matches one of the values in the array, scroll to the element with the matching data-load-id attribute

I currently have the following:
var scrollingAnchorIds = [];
var getTheseIds = $(".anchor-content").each(function() {
scrollingAnchorIds.push($(this).data('load-id'));
});
console.log(scrollingAnchorIds);
$(window).bind("load", function() {
if(document.URL.indexOf(scrollingAnchorIds[i]) >= 0){
$('html,body').animate({scrollTop: elementWithMatchingDataLoadIdGoesHere.offset().top - 50},850);
}
});
I get the values of each data-load-id, add them to array. Right now I'm stuck on checking when the pages loads, does the url contain that hash value, if so, scroll to the element with the matching value.
sample html of what element it would scroll to:
<div data-load-id="#83" class="anchor-content"></div>
<div data-load-id="#91" class="anchor-content"></div>
<div data-load-id="#99" class="anchor-content"></div>

When thinking about it, most of your code seems excessive. Try something like this:
$(function(){
$('html,body').animate({scrollTop: $("[data-load-id='" + window.location.hash + "']").offset().top - 50},850);
});
I made a fiddle also, though window.location.hash does not work in this.

scrollTop to active element in a overflow scroll div

I have a specific question about .scrollTop. I have a div with a specific height and a lot of p tags inside:
<div id="scroll">
<p>name1</p>
<p>name2</p>
<!-- till name50 -->
</div>
depending on the name you click it gets a class .active. What I then want to do is scroll the div so, that the name is at the top. So what I get is that I can use scrollTop in an animate function like this:
$('#scroll').animate({scrollTop: value });
but how can I get the var value. I tried it with
var value = $('#scroll p').hasClass('active').position().top;
But somehow it does not work.
Some help is much appreciated.

You need to check scrollTop() for the container #scroll and add that back to the position() arg.
var $scroll = $('#scroll');
$('p').click(function(e){
var $this = $(this);
$scroll.animate({
"scrollTop": $this.position().top + $scroll.scrollTop()
}, 1000);
});

To just get the value:
var value = $('#scroll').scrollTop();

How do I show an element using the below JQuery code?

CODE:
$(document).ready(function() {
$('.clicker').on('click', function(e){
e.preventDefault();
var $btn = $(this);
$btn.toggleClass('opened');
var heights = $btn.hasClass('opened') ? 300 : 100 ;
$('#thiswillexpand').stop().animate({height: heights });
});
});
By default I want #thiswillexpand to be hidden so I am going to use display:none; But when .clicker is clicked I want it to show and then expand as the script is supposed to.
Question:
How do I show #thiswillexpand when .clicker is clicked while still retaining whatever the script is doing?

I think what you are looking for is to simply add a call to the show() function -
$('#thiswillexpand').show().stop().animate({height: heights });
The show() function is chainable, so you can just insert it before the calls to the other stop and animate functions.

Add new item to bottom of scrollabe div

I'm trying to append a div to the bottom of a another div, by clicking a button in javascript, but once the height of the outer container is reached, it no longer scrolls the list to the bottom, after an insert.
Please see the fiddle here
If you click the red add button until you get to about 13 items in the list, it seems something goes wrong with the scrollTop function, and it it no longer functions correctly (hovers around the same spot in).
I'm pretty lost on this, and have tried a bunch of different combinations of css settings for both the container and side div. Please help me.

I've reformatted your code to be more jQuery-esque. The main change, however, was to change the list.scrollTop() function so that it just scrolls to the bottom of list:
$(document).ready(function() {
var list = $("#q-d-list");
$(document).on('click', '#add', function() {
$('.active', list).removeClass("active");
var count = list.children().length + 1;
var active = $('<div />', {
'data-qid': count,
'class': 'mli active'
}).text('q' + count).appendTo(list);
list.scrollTop(list[0].scrollHeight);
});
});​
Demo: http://jsfiddle.net/MrvcB/19/

Use
list.scrollTop(list.get(0).scrollHeight);
rather than
list.scrollTop($(".active").offset().top);

Try:
$(document).ready(function () {
var count = 2;
$("#add").live("click", function () {
var list= $("#q-d-list");
// remove the active class from the old item
var $clone = $(list.find("div:last-child").removeClass("active").clone());
count+=1;
var str_count = "q"+count.toString();
$clone.addClass("active").attr("data-qid",str_count).text(str_count);
list.append($clone);
list.scrollTop(list.get(0).scrollHeight);
});
});

JQuery: Using :not(.active) selector, and adding an Active class, to the item selected

I'm new to Javascript and am having a bit of an issue with using a NOT selector, and adding a class during the function, hopefully this will make sense to someone.
I am creating a small gallery, and my goal is to have clickable navigation, however the active image will redirect to another page when clicked.
Code is as follows:
$("ul#mainGallery li:not(.active) a").click(function(){
var thisListClass = $(this).parent().attr('class');
var activeListId = $(this).parent().attr('id');
var newMarginLeft = (activeListId-3) * -200;
var animateAction = {};
animateAction['margin-left'] = newMarginLeft + 'px';
$("ul#mainGallery").animate(animateAction, 1000);
$('li.active img').animate({width:'100px', height:'100px'},1000)
$(this + 'img').animate({width:'300px', height:'300px'},1000)
$(li.active).removeClass('active');
$(this).parent().addClass('active');
return false;
I know there is likely a much better way to do this, but I can't get my head around it.
Edit: I should probably say what the problem is...
When an active image is clicked, it follows the hyperlink all is well.
When a non active image is clicked, it begins the animation, then (i assume) when the 'active' class is added, instead of returning false, it returns true and follows the hyperlink.

You are binding the click event to $("ul#mainGallery li:not(.active) a") whenever that code is run (presumably on document load). The items which are not active at that point will have that item bound, and changing the class afterwards on other items won't bind this event to them. You will need to either change how you bind it or check inside the function whether the item has that class.
Something like this:
$("ul#mainGallery li a").click(function(){
if(!$(this).parent().hasClass('active')){
var thisListClass = $(this).parent().attr('class');
var activeListId = $(this).parent().attr('id');
var newMarginLeft = (activeListId-3) * -200;
var animateAction = {};
animateAction['margin-left'] = newMarginLeft + 'px';
$("ul#mainGallery").animate(animateAction, 1000);
$('li.active img').animate({width:'100px', height:'100px'},1000)
$(this + 'img').animate({width:'300px', height:'300px'},1000)
$('li.active').removeClass('active');
$(this).parent().addClass('active');
return false;
}
EDIT, or if you prefer to continue using the same selector with the :not and everything, then switch your click function to .live()

To stop the default behaviour use the preventDefault() function
$("ul#mainGallery li:not(.active) a").click(function(e){
e.preventDefault(); // will stop the default behaviour
}
