Following jQuery isn't working. Take a look

Code:
<div>
Back
<div class="outer"></div>
Next
</div>
<div>
Back
<div class="outer"></div>
Next
</div>
jQuery code:
$('.next').click(function() {
$('.next').prev().animate({
scrollLeft: '+=150'
}, 200);
});
$('.back').click(function() {
$('.back').next().animate({
scrollLeft: '-=150'
}, 200);
});
Error:
Basically I have more codes with the same classes as above and I want to scroll the code which is clicked. But the code written above scroll all the ".outer" on the page. Each set of the code is in different div. The inside material of the "outer" isn't provided which is scroll able.

You need to execute the code using current element context i.e. this. Also animate the siblings of parent element so traverse up using $(this).closest('div') then use .prev() or next()
$(function() {
$('.next').click(function() {
$(this).closest('div').prev().animate({
scrollLeft: '+=150'
}, 200);
});
$('.back').click(function() {
$(this).closest('div').next().animate({
scrollLeft: '-=150'
}, 200);
});
});

Simple Use $(this) for get current Object
$('.next').click(function () {
$(this).prev().animate({ scrollLeft: '+=150'}, 200);
});
$('.back').click(function () {
$(this).next().animate({ scrollLeft: '-=150'}, 200);
});

Don't forget to wrap your code in a document ready function.
<script>
$(document).ready(function() {
$('.next').click(function () {
$(this).prev().animate({ scrollLeft: '+=150'}, 200);
});
$('.back').click(function () {
$(this).next().animate({ scrollLeft: '-=150'}, 200);
});
});
</script>
Also using the on method is better for event binding, e.g.
<script>
$(document).ready(function() {
$('.next').on('click', function () {
$(this).prev().animate({ scrollLeft: '+=150'}, 200);
});
$('.back').on('click', function () {
$(this).next().animate({ scrollLeft: '-=150'}, 200);
});
});
</script>
Edit:
As #GuruprasadRao pointed out, I'm assuming you are already but make sure you're using a HTML5 doctype otherwise you'll need to add type="text/javascript" to your script tag.

SlideToggle from botton/top to left/right

I have a little problem that I'd love to solve on my website.
Have a look at this JSFIDDLE — https://jsfiddle.net/sm25t089/
This is the javascript code:
$(document).ready(function () {
$(".bottoni").hide();
$(".reveal").click(function () {
$(this).toggleClass("active").next().slideToggle(200, "linear");
if ($.trim($(this).text()) === '(+)') {
$(this).text('(×)');
} else {
$(this).text('(+)');
}
return false;
});
$("a[href='" + window.location.hash + "']").parent(".reveal").click();
});
I'd love the menu to move from out-of-the-screen to the left, to the right, instead the actual bottom to top.
Thanks for the help.

here is one solution using css3
transition:0.3s;
https://jsfiddle.net/sm25t089/1/
if you prefer using only ccs2 then you can do the same with a jquery animate

You can use the jQuery method .animate()
(function($) {
$(document).off("click.slide").on("click.slide", ".reveal", function (e) {
var $self = $(this),
$menu = $(".bottoni"),
isActive;
e.preventDefault();
$self.toggleClass("active");
isActive = $self.hasClass("active");
$self.text(isActive ? "(x)" : "(+)");
$menu.animate({
"left": isActive ? "21px" : "-100px"
}, 200, "linear");
});
})(jQuery);
Here are a JSFiddle with the sample: https://jsfiddle.net/sm25t089/3/

scroll down function on click

below is the code I have for scrollTop. It works fine when I target a specific pixel, but I want to scroll down 300px, instead of scrollTop a certain div on click. can anyone help?
<div id="button"></div>
<div1 style="height:300px;">img1</div>
<div2 style="height:300px;">img2</div>
<div3 style="height:300px;">img3</div>
<div4 style="height:300px;">img4</div>
$(function() {
$("#button").on("click", function() {
$("html, body"). animate({"scrollTop":$().offset().top-300}, 1000);
return false;
});
});

Try using window.scrollBy(0,300);

$().offset().top doesnt do much of anything. Replace it with window.scrollY
$(function() {
$("#button").on("click", function() {
$("body").animate({"scrollTop": window.scrollY-300}, 1000);
return false;
});
});
Also negative is up and positive is down when we're talking about scrolling so you probably want to add 300 instead.

I think it's the best way.
var body = $('html, body');
$('#button').click(function() {
var n = $(document).height() - $(window).height();
body.stop().animate({scrollTop: n }, 1000, function() {
});
});

how to animate height of a div back-jquery

I'm trying to show some part of a div and animate it to 100% when the div is clicked.
and I want to animate it back to the initial height of the div if it's clicked again.
this is what i have so far,but it doesn't work. can anyone help?
#mydiv {
height:150px;
width: 100%;
overflow:hidden;
}
<script type="text/javascript">
$(document).ready(function(){
$("#mydiv").click(function(){
$(this).animate({height: '100%'}, 300);
}, function() {
$(this).animate({height: '150px'}, 300);
});
});
</script>

click() doesn't accept two function arguments, previously there was a toggle() function that performed how you need it but it has now been deprecated and removed from jQuery.
Since your use case is pretty simple, I believe something like this would be enough:
$("#mydiv").click(function () {
var $this = $(this);
$this.animate({
height: $this.height() == 150 ? '100%' : 150
}, 300);
});
Demo fiddle

This should do the job for you.
jQuery:
$(document).ready(function() {
$("#mydiv").toggle(
function() {
$(this).animate({height: '100%'}, 300);
};
function() {
$(this).animate({height: 150}, 300);
});
});

alternatives to jquery animate?

On hover I want my div to scroll down.
I know i can use the .animate({left: 0}, "slow"); but this doesnt go down but what else does jquery have to offer?
Here is my jsfiddle: http://jsfiddle.net/WZvPk/4/
hover over the sectors box and you will see the "view project" move down. I need it to move down in a slow fashion similar to http://www.jeremymartin.name/examples/kwicks.php?example=3
Then need the opacity to be so my image is darker.
edit: slide down wont work with this:
$(".sectorGrid").hover(
function () {
$(this).children(".sectorImage").children(".showme").css("display", "block").css("margin-top", "-5px");
},
function () {
$("div.sectorImage div.showme").css("display", "none");
}
);

You probably want jQuery slideDown, see: http://api.jquery.com/slideDown/
Edit:
So something like this:
$(".sectorGrid").hover(
function () {
$(this).children(".sectorImage")
.children(".showme")
.css("display", "block")
.css("margin-top", "-5px")
.slideDown("slow");
},
function () {
$("div.sectorImage div.showme").hide();
}
);
You could also, add a css class with the margin-top and display-block property, like:
.slideDown { display: block !important; margin-top: 5px !important; }
/* !important so they won't be overwritten..*/
Then you can do something like this:
$(".sectorGrid").hover(
function () {
$(this).children(".sectorImage")
.children(".showme")
.addClass("slideDown")
.slideDown("slow");
},
function () {
$("div.sectorImage div.showme").hide();
}
);

What about css3 transitions? They are smooth and are starting to be widely supported.
Here's an example which doesn't use javascript at all.
Update : Another example that doesn't use opacity.

$(".sectorGrid").hover(
function () {
$(this).children(".sectorImage").children(".showme").css("display", "block").animate({"margin-top": "-5px"}, "slow");
},
function () {
$(this).children(".sectorImage").children(".showme").css("display", "none").css("margin-top","-25px");
}
);​

​Now it works
$(".sectorGrid").hover(
function () {
$(".showme").css("margin-top", "-25px");
$(this).children(".sectorImage").children(".showme").css("display", "block").animate({"margin-top": "-5px"}, 'slow');
},
function(){
$(".showme").css("display", "none")
}
);
