JQuery on click link with href atribute

I have the following code structure. Its a set of wordpress tabs. I have many tabs all over the website, using Jquery i want to trigger a function when a user clicks one of the links, however i cant apply a ID atribute so my funtion below doesnt work...any suggestions?
JQUERY
$('#1485856532455-70ee0dfe').on('click', function() {
$('.otherdiv').css('background-image', 'url(http://placehold.it/200x200/ff0000)');
})
HTML
<ul class="vc_tta-tabs-list">
<li class="vc_tta-tab">
<span class="vc_tta-title-text">Title</span>
</li>
<li class="vc_tta-tab">
<span class="vc_tta-title-text">Title</span></li>
</ul>

You can't select them by ID because they don't have IDs. But you can use CSS Atrribute-Equal Selector to get them by href attribute. Like this:
$('[href="#1485856532455-70ee0dfe"]').on('click', function() {
// ...
}
More CSS Selectors here.
Working code snippet:
$('[href = "#1485856532455-70ee0dfe"]').click(function() {
alert("#1485856532455-70ee0dfe was clicked! Hoooray!");
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="vc_tta-tabs-list">
<li class="vc_tta-tab">
<a href="#1485856532455-70ee0dfe"> <span class="vc_tta-title-text">Title</span>
</a>
</li>
<li class="vc_tta-tab">
<span class="vc_tta-title-text">Title</span>
</li>
</ul>

Use attribute selector then :
$('[href="#1485856532455-70ee0dfe"]').on('click', function() {....});

$('#1485856532455-70ee0dfe').on('click', function() { - means that on page we have some element with id 1485856532455-70ee0dfe. In your html code no id with text 1485856532455-70ee0dfe, thats why your code not work.
You have two case to fix:
add id's to needed element
change js to $('[href="1485856532455-70ee0dfe"]').on('click', function() {

You cant give a id to a link like that. However you can select the link with jquery by doing $('[href="#1485856532455-70ee0dfe"]').on('click', function() {....});

Targeting a nested <a> element and removing its href attribute using JavaScript/jQuery

I need a little help with removing the href element of the below 'a' element:
<div class="carousel__tape-item js-product">
<div class="sale-content__cell">
</div>
</div>
This is my attempt but it doesn't work:
var a = $(".carousel__tape-item .sale-content__cell");
a.find("a").removeAttr("href");
Any ideas?

You want to use the multiple selector syntax for jquery
$(document).ready(function() {
$('.carousel__tape-item.js-product').find('a').removeAttr('href');
});

List of all element which have rel property

I have different types of tag which have "rel" property using jQuery or javascript.
<a rel="popup10">test</a>
<div>text2</div>
<p rel="popup20">text3</p>
<span rel="other">test4</span>
I want list of all element which have rel property with value like "popup", ignore number 10 or 20 whatever. i don't want span tag because it has rel property but value is not popup.

You need to use attributes selector. You can select all element as your requirement like this:
$('*[rel^="popup"]')
try like this:
$('*[rel^="popup"]').each(function(){
alert($(this).text());
//do what ever you want
})
demo

Use the following, example I want all the div have ID only, then
<div id='test1'>aaaa</div>
<div id='test2'>bbbb</div>
<div id='test3'>cccc</div>
<div>No ID!</div>
JQuery
$(document).ready(function () {
$("div[id]").each(function () {
alert(this.id);
});
});

Onmouseover change CSS class from other element

I'm trying to make an JS, but since I'm not an expert on that, maybe someone could help me. I was searching for that in Google and in Stack Overflow, but didn't find what I need. I just found onmouseover that change the class in element itself. But I want something different:
I want to make a onmouseover on a tag to change the class closed to open in other element. Example:
Link
<ul class="dropdown closed"><li>Item</li></ul>
Regards,

If you include jQuery:
Add id for your elements:
Link
<ul class="dropdown closed" id="ul1"><li>Item</li></ul>
Javascript:
$("#a1").mouseover(function(){
$("#ul1").addClass("open").removeClass("closed")
})

You can use Link
And JS:
function changeClass() {
document.getElementById("other-element").className = "open";
}
More advanced JSFiddle: http://jsfiddle.net/eRdHJ/1/

<a href="#" onmouseover=$("ul.dropdown").addClass("open").removeClass("closed")>Link</a>
<ul class="dropdown closed"><li>Item</li></ul>
Here is the jsfiddle : http://jsfiddle.net/eRdHJ/2/

This will access the first <ul> on the page. To narrow it down you need to do a getElementById first to get the elements based on tag name from that point. It will then only select the children from that tag with that certain ID-name;
<script>
function changeUl() {
// Get the first found UL, anywhere in the body
document.getElementsByTagName('ul')[0].className = 'otherName';
}
</script>
Link
With ID
<script>
function changeUl() {
var wrapper = document.getElementById('wrapper');
wrapper.getElementsByTagName('ul')[0].className = 'otherName';
}
</script>
<div id="wrapper">
Link
</div>
You might want to check if there are any found tho. [0] might trigger an undefined/error if there are no <ul> found.

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.
