Capturing the text of the closest span element with a specific class

I'm trying to fetch the text of a span that has a given class -> closest to the click via Google Tag Manager. Is it possible via plain JS or JQuery?
The code looks like this:
<a class="contenttile" href="/mypage" style="height: 193px;">
<div class="imageContainer" style="height: 97px;">
<img src="http://http:someadress.com/foto.jpg" class="blurr" alt="">
</div>
<div class="textContainer">
<span class="text3">My text</span>
<br>
</div>
</a>
What I want to return via a function is My text.
I was trying different snippets found here, but since im a JS lame I couldn't adjust it to work properly.
For example this one:
function(){
var ec = {{Click Element}};
var x = $(ec).closest('span');
return x.innerText;
}

since you are using jQuery
return ec.find('.text3').text();

In GTM, your click may register two events: gtm.click and gtm.linkClick. Depending on which one your tag is set to fire on (ie. you can set it to fire on all clicks or just links), then you could use either of the following:
If using just links, then $(ce).find('.textContainer').find('span').text()
If using all clicks, then $(ce).closest('span').text()

targeting classes with jquery

Need to pass information from one class to another in a way that will validate. Current approach is a mess- works but does not validate.
I need to pass text inside a p tag to another element on the page. Right now i'm using a tag attributes to pass this info along. Super messy.
<div class="element-item">
<div class="text-panel">
<div class="text-cell">
<a class="ajax" href="ajax/bkdesks.html" id="Brooklyn Desks" dir="BROOKLYN, NY">
<p class="link"><img src="img/chainlink.png" width="60" height="60" alt="link" alt=""/></p>
<p class="name">Brooklyn Desks</p>
<p class="dir">Brooklyn, NY</p>
</a>
</div>
</div>
And then jQuery:
$('.ajax').click(function(e) {
e.preventDefault();
$('#projects-head .titlehead').text($(this).attr('id'));
$('#projects-head .subhead').text($(this).attr('dir'));
$('#project').load($(this).attr('href'));
});
titlehead and subhead are the other elements on the page whose content is being replaced. I would much rather grab the contents of the p tags below than put everything in the a id & dir. But i cant figure out the jquery to target them.

The p.name and p.dir elements are descendant elements of the clicked .ajax element so you can use .find()
$('.ajax').click(function (e) {
e.preventDefault();var $this = $(this);
$('#projects-head .titlehead').text($(this).find('.name').html());
$('#projects-head .subhead').text($(this).find('.dir').html());
$('#project').load($(this).attr('href'));
});

How to get a div which is removed from the DOM when it's parent has been made .empty()?

I have a div in a HTML file
"<div id="abc" hidden="hidden">
<div id="statIndicator">
<span id="imgInd" class="status-indicator-border">
<img src="../../LibSrc/SharedResources/IMG/loading-trace.gif" />
</span><span id="messageIndicator">Updating Plots...</span>
</div>
</div>"
I insert the statIndicator div in another div using append.
so that div becomes
<div id="parentDiv">
<div id="statIndicator">
<span id="imgInd" class="status-indicator-border">
<img src="../../LibSrc/SharedResources/IMG/loading-trace.gif" />
</span><span id="messageIndicator">Updating Plots...</span>
</div>
</div>
On refresh I write $('#parentDiv').empty() it deletes whatever is inside the 'parentDiv'.
But when I try to append statIndicator using $('#statIndicator'), it return "[]", though I have the 'statIndicator' div in Html.
Is there a way in which I can get the 'statIndicator' div?

No. $.empty() deletes the contents, so your "statIndicator" div no longer exists at all.
Just remove it from "parentDiv" before you call $.empty(). Either store it in a variable or put it back where it started, in "abc".

I think jquery.append() moves the selected elements without making a copy. So you can explicitly create a copy using the .clone() method and append it's result. Something like:
$('#abc #statIndicator').clone().appendTo('#parentDiv');
This is creating a copy and then appending it at the new location.
Once you do this there will be two divs with the same id, so it will be a good idea to always reference the statIndicator's parent container in your selectors.

You can use .detach() function if you want only parentDiv to be removed

Easiest way to get element parent

Suppose i have this structure of elements:
<div class="parent">
<div class="something1">
<div class="something2">
<div class="something3">
<div class="something4"></div>
</div>
</div>
</div>
</div>
And code like this:
$(".something4").click(function(){
//i could do it like this...
$(this).parent().parent().parent().parent().parent();
});
But that seems to be stupid, is there a better way to do this?
also i can't just say $(.parent) because there are many divs like this with class parent in my page.

Use .closest(selector). This gets the first element that matches the selector, beginning at the current element and progressing up through the DOM tree.
$('.something4').click(function() {
$(this).closest('.parent');
});

Use .closest():
$('.something4').click(function() {
$(this).closest('.parent');
});

I think you should try this
$(this).parents(".parent");
But I don't know where on the page are the other divs with this class :)

You could always use .parentNode (standard JavaScript). It's generally a bad idea to use class names that coincide with function/variable names from the library you're using (this goes for any language). Making your class names more unique is a better approach (for instance, "scparent" instead of "parent", if the name of your application was "Super Calculator" or something). This avoids conflicts such as the one you're describing.
I would caution using .closest(), simply because you may create a function like this:
function getParentElem() {
return $(this).closest('div');
}
And it would grab the parent div's in your code just fine, but if down the road you add a table for displaying data, and you run the function through a child element of the table, you will have to create another implementation that selects the table element, because that's what you now want:
<div id="tableParent">
<table id="dataTable">
<tr id="target1">
<td>Some data.</td>
</tr>
</table>
</div>
By using your function getParentElem() on the tr element, you'll end up grabbing the div with id="tableParent", rather than the actual parent, which is the table element. So, unless you've delineated your parent classes appropriately all the way through your code (which can be a pain and isn't always efficient), you may run into problems. Especially if at any point you're creating elements programmatically, or reading in data from another 3rd-party library or script.
Not saying it's not good to use .closest()... just pointing out a possible "gotcha".

i would suggest adding to the div parent an id like 'parent_1' etc. and in every son you keep the id in the rel attr
<div id="parent_1" class="parent">
<div rel="1" class="something1">
<div rel="1" class="something2">
<div rel="1" class="something3">
<div rel="1" class="something4"></div>
</div>
</div>
</div>
</div>
$(".something4").click(function(){
//i could do it like this...
$('#parent_' + $(this).attr('rel'));
});

Use same div to toggle different parts of the page

Hello I have the following code:
Javascript/jQuery:
$(document).ready(function() {
$(".clickMe").click(function() {
$(".textBox").toggle();
});
});
Html code printed with a for loop:
<a class="clickMe">Toggle my text</a>
<br />
<div class="textBox"> - This text will be toggled</div>
<a class="clickMe">Toggle my text</a>
<br />
<div class="textBox"> - This text will be toggled 2</div>
<a class="clickMe">Toggle my text</a>
<br />
<div class="textBox"> - This text will be toggled 3</div>
I would like to be able:
When the page loads I want the to be hidden and toggle on click.
Using the same ids for <a class="clickMe"> and <div class="textBox"> to be able to toggle or hide the correct/equivalent <div> element.
jsFiddle code:

Thanks
Edit 1: Class instead of Id
Edit 2: Fixed jsfiddle link

id are supposed to be unique
you should use class to do this
[EDIT] updated the jsfiddle to fit Marko Dumic's solution: http://jsfiddle.net/SugvH/

Something like this should do the trick:
$(document).ready(function() {
var divs = [];
$(".textBox").each(function(index) {
divs[index] = this;
});
$(".clickMe").each(function(index) {
$(this).click(function() {
$(divs[index]).toggle();
});
});
});

ID must (as per spec) be unique on the page. You can easily rewrite this to use class attribute:
<a class="clickMe">Toggle my text</a>
<br />
<div class="textBox"> - This text will be toggled</div>
<a class="clickMe">Toggle my text</a>
<br />
<div class="textBox"> - This text will be toggled 2</div>
...
Initially, you need to either hide div.textBox when DOM becomes ready, or hide it using CSS.
Then you attach click handlers to a.clickMe:
$(function () {
$('a.clickMe').click(function () {
// find first of following DIV siblings
// with class "textBox" and toggle it
$(this).nextAll('div.textBox:first').toggle();
});
});
However, maybe you don't control the markup but desperately need this done, you can keep your markup as it is and still make it work due to the fact that jQuery uses Sizzle framework to query the DOM which can be forced around the limitation of document.getElementById() (which returns only one element).
E.g. suppose you used id instead of class, if you write $('#clickMe'), you'll get the jQuery collection of only one element (jQuery internally used .getElementById() to find the element), but if you write $('#clickMe'), you get the collection of all elements with the id set to "clickMe". This is because jQuery used document.getElementsByTagName('a') to find all anchors and then filtered-out the elements (by iterating and testing every element) whose attribute value is not "clickMe".
In that case (you used your original markup), this code will work:
$(function () {
$('a#clickMe').click(function () {
$(this).nextAll('div#textBox:first').toggle();
});
});
Again, don't do this unless you absolutely need to!

$(document).ready(function() {
$("a").click(function() {
$(this).parent().find("div").toggle();
});
});
Use something similar to this.

Try appending an index to each pair of a/div's ids (clickme1 and textbox1, etc). Then when an a is clicked, read the id, take the index off the end, and show/hide the textbox with the same index.
