Targeting Multiple Elements with One Function

I have a function that assigns dynamic classes to my div's. This function is a that runs on the page. After the page loads, all 10 of my primary 's have classes ".info1" or ".info2" etc...
I am trying to write a Jquery function that changes the class of the div you click on, and only that one. Here is what I have attempted:
$(".info" + (i ++)).click(function(){
$(".redditPost").toggleClass("show")
});
I have also tried:
$(".info" + (1 + 1)).click(function(){
$(".redditPost").toggleClass("show")
});
And
$(".info" + (i + 1)).click(function(){
$(".redditPost").toggleClass("show")
});
EDITED MY HTML: DIV RedditPost is actually a sibling to Info's parent
<div class="listrow news">
<div class="newscontainer read">
<div class=".info1"></div>
<div class="redditThumbnail"></div>
<div class="articleheader read">
</div>
<div class="redditPost mediumtext"></div>
</div>
My issue is two fold.
The variable selection for ".info" 1 - 10 isn't working because i doesn't have a value.
If I did target the correct element it would change all ".redditPost" classes instead of just targeting the nearest div.

Try like this.
$("[class^='info']").click(funtion(){
$(this).parent().find('.redditPost').toggleClass("show");
});
Alternative:
$('.listrow').each(function(){
var trigger = $(this).find("[class^='info']");
var target = $(this).find('.redditPost');
trigger.click(function(){
target.toggleClass("show");
});
});

Try this
$("div[class*='info']").click(function(){
$(this).parent().find(".redditPost").toggleClass("show")
});
Explanation:
$("div[class*='info'])
Handles click for every div with a class containing the string 'info'
$(this).parent().find(".redditPost")
Gets the redditPost class of the current clicked div

Since the class attribute can have several classes separated by spaces, you want to use the .filter() method with a RegEx to narrow down the element selection as follows:
$('div[class*="info"]').filter(function() {
return /\binfo\d+\b/g.test( $(this).attr('class') );
}).on('click', function() {
$(this).siblings('.redditPost').toggleClass('show');
});
.show {
display:none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="listrow news">
<div class="newscontainer read">
<div class="info1">1</div>
<div class="redditThumbnailinfo">2</div>
<div class="articleheader read">3</div>
<div class="redditPost mediumtext">4</div>
</div>
</div>

make links with javascript/jquery from html class

in my site have 3 box, how create with js a link from a html class
example my box is this:
<div class="box1">content</div>
<div class="box2">content</div>
<div class="box3">content</div>
how create a link for class box1,box2,box3

The question is ambiguous. if this is what you want:
<div id = "box1" class="box1">content</div>
<script>
var x = document.getElementsByClassName("box1");
$( ".box1" ).replaceWith( "content" );
</script>

I'm guessing this is what you are trying to do, turning the class into a link. http://jsfiddle.net/xthne2bm/1/
HTML
<div class="box1">content</div>
<div class="box2">content</div>
<div class="box3">content</div>
JQuery
$('[class^="box"').each(function () {
var link = $(this).attr('class');
$(this).wrapInner('<a>').find('a').attr('href', link);
});

Determining which element was clicked and conditionally choosing which method to call

I am attempting to use JQuery to make 3 thumbnails into buttons that each open up their own page element with details regarding the picture.
Right now I have succeeded in making it so that any thumbnail causes a page element (of the class "description") to scroll open and closed when any thumbnail (from the class "thumbnail") is clicked.
How do I check which thumbnail is clicked on so that I can open a different description corresponding to that specific thumbnail? (This is what I was attempting to do with the "select").
var main = function() {
$('.thumbnail').click(function(select) {
var description = $('.game-descriptions').children('.description');
if( description.is(":hidden")) {
description.slideDown("slow");
}
else
description.hide();
});
}
$(document).ready(main);

Use a data attribute to specify what the thumbnail click is targeting, example: data-target="#game-1", add IDs to your descriptions that match and use data() to use the attribute value of #game-1 a jQuery selector.
Here is a demo
JS
$('.thumbnail').click(function() {
var gameId = $(this).data('target');
$(gameId).slideToggle().siblings(':visible').slideToggle();
});
HTML
<img class="thumbnail" data-target="#game-1" />
<img class="thumbnail" data-target="#game-2" />
<div class="game-descriptions">
<div id="game-1" class="description"></div>
<div id="game-2" class="description"></div>
</div>
Any toggling like toggle(), slideToggle(), fadeToggle() handles the is hidden or is visible

jsFiddle
The parameter to the click function is a jQuery event object, which can be useful in adding some event handling logic. However, within the context of the handler, this refers to the element which triggered the click event, and is typically sufficient for any targeted logic.
Assuming the thumbnails and descriptions have similarly named IDs, for example, you can do something like this:
$(function () {
$('.thumbnail').click(function (event) {
var descId = this.id.replace("thumb", "desc");
var description = $('.game-descriptions').children('#' + descId);
// or simply $("#" + descId);
description.toggle("slow");
});
});
HTML
<div>
<div class="thumbnail" id="thumb-1">Thumb 1</div>
<div class="thumbnail" id="thumb-2">Thumb 2</div>
<div class="thumbnail" id="thumb-3">Thumb 3</div>
</div>
<div class="game-descriptions">
<div class="description" id="desc-1">Description One</div>
<div class="description" id="desc-2">Description Two</div>
<div class="description" id="desc-3">Description Three</div>
</div>
Your technique for targeting the correct 'description' will depend on your actual DOM structure, however.
Also note that I substituted the toggle method for your if statement, as the logic you have is equivalent to what it does (i.e. toggling object visibility).

Jquery Show Hide with attribute

How to get value from custom attribute to be used in if else condition?
I want to switch button between show & hide . if show button clicked it will hiden and the hide button showed. And also the same for opposites.
So i can do show hide for my divs.
Here's my codes
<div class="wrapper">
<a class="show_detail" target="1" style="display:block">+ Show</a>
<a class="hide_detail" target-hide="1" style="display:none">- Hide</a>
<div class="event_down" id="event_down1" style="display:none">
Content 1
</div>
<a class="show_detail" target="2" style="display:block">+ Show</a>
<a class="hide_detail" target-hide="2" style="display:none">- Hide</a>
<div class="event_down" id="event_down2" style="display:none">
Content 2
</div>
<a class="show_detail" target="3" style="display:block">+ Show</a>
<a class="hide_detail" target-hide="3" style="display:none">- Hide</a>
<div class="event_down" id="event_down3" style="display:none">
Content 3
</div>
</div>
CSS:
.show_detail{cursor:pointer; color:red;}
.hide_detail{cursor:pointer; color:red;}
JS :
$('.show_detail').click(function(){
var atribut_show = $('.show_detail').attr('target');
var atribut_hide = $('.hide_detail').attr('target-hide');
if (atribut_show == atribut_hide){
$('.hide_detail').show();
$(this).hide();
}
$('.event_down').hide();
$('#event_down'+$(this).attr('target')).show();
});
and here's MY FIDDLE need your help to solve it.

in order to get custom attributes their name must start with "data-". For example your custom attribute target would be "data-target". After that you can get them using something like $("#myElement").getAttribute("data-target").

You are getting object array list you have to get only the current object
Check updated fiddle here
"http://jsfiddle.net/p7Krf/3/"
$('.show_detail').click(function(){
var atribut_show = $(this).attr('target');
$('.hide_detail').each(function(element){
if($(this).attr("target-hide")==atribut_show){
$(this).show();
}
});
$(this).hide();
$('#event_down'+atribut_show).show();
});

The following javascript made it function for me. You should however consider calling your attributes data-target and data-target-hide as your specified attributes are not actually valid. It will function, but you could run into problems if you don't change the attribute names.
$('.show_detail').click(function(){
var atribut_show = $(this).attr('target');
$('.hide_detail[target-hide="'+atribut_show+'"]').show();
$(this).hide();
$('#event_down'+atribut_show).show();
});
$('.hide_detail').click(function(){
var atribut_hide = $(this).attr('target-hide');
$('.show_detail[target="'+atribut_hide+'"]').show();
$(this).hide();
$('#event_down'+atribut_hide).hide();
});

If href equals id of another div do function

I have a hidden div with the details of a thumbnail that is visible on the page. When you click on the thumbnail, it should fadein or slideup the div with details.
I have set with jquery incremented ID's to each ".portfolio-item-details" to identify each one and then have set with jquery the same ID's to the href of the thumbnail.
<section id="portfolio1" class="portfolio-item-details hidden">content</section>
<a class="open-portfolio-item-details" href="#portfolio1" title="">
<img src="thumbnail.jpg">
</a>
<section id="portfolio2" class="portfolio-item-details hidden">content</section>
<a class="open-portfolio-item-details" href="#portfolio2" title="">
<img src="thumbnail.jpg">
</a>
Since this is done dynamically, how can I with jquery fadeIn or slideUp the ".portfolio-item-details" if the href is equal to the ID. Basically thumbnail with "#portfolio1" should slide up the div with "#portfolio1" on click.
This is my jquery code which to add the IDs and HREF is working perfectly but not working to slideUp or fadeIn the div with the same ID.
$(document).ready(function () {
var i=0;
$(".portfolio-item-details").each(function(){
i++;
var newID="portfolio"+i;
$(this).attr("id",newID);
$(this).val(i);
});
var i=0;
$(".open-portfolio-item-details").each(function(){
i++;
var newReadMoreHREF="#portfolio"+i;
$(this).attr("href",newReadMoreHREF);
$(this).val(i);
if ($(".portfolio-item-details").attr("id") == "newReadMoreHREF") {
$(this).fadeIn();
}
});
});
SOLUTION
Thanks to Austin's code, I was able to modify it to work with mine.
Check here: http://jsfiddle.net/jdoimeadios23/xpsrLyLz/

You want something like this?
HTML
<div class="image" value="1">
<img src="thumbnail.jpg" />
</div>
<div id="portfolio1" class="details">details</div>
<div class="image" value="2">
<img src="thumbnail.jpg" />
</div>
<div id="portfolio2" class="details">more details</div>
JS
$(document).ready(function () {
$('.details').fadeOut(1);
$(".image").click(function () {
var num = $(this).attr("value");
$("#portfolio"+num).fadeIn(1000);
});
});
JSFiddle Demo
You don't even need to bother with ID's so long as the next div below each image is it's details.

The problem is in this block
if ($(".portfolio-item-details").attr("id") == "newReadMoreHREF") {
$(this).fadeIn();
}
Because you're having two errors, the first one is that newReadMoreHREF is a variable, not a string in your HTML or a value to any variable and so on.
Second thing is, that in the variable declaration you're using "#portfolio"+i;, which would be good if you were about to select an element. But using it in the jQuery iif statement with .attr('id') will again cause a havoc.
The thing that you need is something like this
$(".open-portfolio-item-details").each(function(){
i++;
var newReadMoreHREF="portfolio"+i; // removed #
$(this).attr("href",newReadMoreHREF);
$(this).val(i);
if ($(".portfolio-item-details a").attr("id") == newReadMoreHREF) {
// you need to access the hyperlink in the element, not
// the element itself. this portfolio1 ID is of a hyperlink
// again here, this is referencing the main iterator.
$(this).fadeIn();
// are you sure you want to fade the .open-portfolio-item-details?
}
});
Removed the hash sign and then called the variable value to check against. It would execute to be true if the condition is true.

Try this:
HTML:
content
<section id="portfolio2" class="portfolio-item-details hidden">content</section>
<a class="open-portfolio-item-details" href="#portfolio2" title="">
<img src="thumbnail.jpg">
</a>
<div id="portfolio1" class="portfolio" hidden>Portfolio 1</div>
<div id="portfolio2" class="portfolio" hidden>Portfolio 2</div>
Jquery:
$('a.open-portfolio-item-details').on('click', function (e) {
e.preventDefault();
var id = $(this).attr('href');
$('.portfolio').hide();
$('.portfolio' + id).fadeIn();
});
Couldn't get the fiddle link for some reason.
Edit:
I don't know the name of the class that shows the content you want displayed, so as an example I'm using portfolio. Try putting this code into a fiddle
