Display A Div When Two Links Click

I am making a plugin for social discount. When user click on Facebook and Instagram follow link then it display a coupon box.
The div display only when user click on both the links. I am not good in java-script so please help me.
<div class="popup">
<div class="social-links">
<h3>Like + Follow = Get Rs 50 Discount</h3>
<img src="images/facebook-logo.png" alt="" />Facebook
<img src="images/facebook-logo.png" alt="" />Instagram
</div>
<div class="coupon">
<p>Congratulations: Your Coupon Code is "Discount50". Use it in Checkout Page.</p>
</div>
</div>
So I want user click on Facebook link and Like Page and then back to website and click on Instagram link and follow the Page. and then he back to website the coupon div display.
Regards

Here is one way of doing it (using css):
var instagramClicked = false;
var facebookClicked = false;
document.getElementById('instagram').addEventListener('click', () => {
this.instagramClicked = true;
this.showCoupon();
});
document.getElementById('facebook').addEventListener('click', () => {
this.facebookClicked = true;
this.showCoupon();
});
function showCoupon() {
if (this.instagramClicked && this.facebookClicked) {
setTimeout(() => document.getElementById('coupon').style = 'display: block', 1000);
}
}
<div class="popup">
<div class="social-links">
<h3>Like + Follow = Get Rs 50 Discount</h3>
<img src="images/facebook-logo.png" alt="" />Facebook
<img src="images/facebook-logo.png" alt="" />Instagram
</div>
<div class="coupon" style="display: none;" id="coupon">
<p>Congratulations: Your Coupon Code is "Discount50". Use it in Checkout Page.</p>
</div>
</div>

add id attributes for links and style attribute, what hide your coupon block like this
<div class="popup">
<div class="social-links">
<h3>Like + Follow = Get Rs 50 Discount</h3>
<img src="images/facebook-logo.png" alt="" />Facebook
<img src="images/facebook-logo.png" alt="" />Instagram
</div>
<div class="coupon" style="display: none;">
<p>Congratulations: Your Coupon Code is "Discount50". Use it in Checkout Page.</p>
</div>
Then add below, variables what keep state (clicked or not) links, click handlers, and function what check is clicked variables like this.
<script>
var facebookClicked = false;
var instagramClicked = false;
document.querySelector("#facebook-link").addEventListener("click", function (e) {
facebookClicked = true;
showCoupon();
});
document.querySelector("#instagram-link").addEventListener("click", function (e) {
instagramClicked = true;
showCoupon();
});
function showCoupon() {
if (facebookClicked && instagramClicked) {
document.querySelector(".coupon").removeAttribute("style");
}
}
</script>

Find previous <a> element?

SOMEUSERNAME
<div class="col s9">
<p id="p_50">Some message</p>
<br>
<br>
<span class="forumtools">
<strong>
<a onclick="quote(\'p#p_50\')">Quote</a>
</strong>
<span class="right">Written SOMEDATE</span>
</span>
</div>
JQuery/JS:
function quote(post) { $(post).text(); }
This works to fetch the posts message, but how do I go about finding the Username?
I have tried using $(post).prev('a').text();, and $(post).parent().prev('a').text();, but nothing seems to work.

You can do it without jQuery. If possible, change the html and pass the current link to the function, like this:
<a onclick="quote(\'p#p_50\', this)">Quote</a>
Then you can just search through all links:
function quote(str, currentLink) {
var allLinks = document.getElementsByTagName("a"); // get all links in document
var index = allLinks.indexOf(currentLink);
if (index > 0) {
var prevLink = allLinks[index-1];
console.log(prevLink); // log it to browser console
} else {
console.log("there is no previous link");
}
}

By looking at the DOM structure, it should work with $(post).parent().prev().text().
Alternative way, how about you wrap all of them with <div>, like this: XD
<div id="message1">
SOMEUSERNAME
<div class="col s9">
<p id="p_50">Some message</p>
<br>
<br>
<span class="forumtools">
<strong>
<a onclick="quote(\'#message1\')">Quote</a> //change to wrapper id
</strong>
<span class="right">Written SOMEDATE</span>
</span>
</div>
</div>
then to get the post text: $(post).find('#p_50').text();
to get the username: $(post).find('a:first').text();

Looking at your sample HTML, if you're at p, just go to parent element and get the closest a and you should be fine:
function quote(post) {
var post = $(post).text();
var user = $(post).parent().closest('a').text();
}

Perhaps using parent() and then previous()
var ancortext = $(post).parent().prev().text();
A function example below.
function username(post) {
return $(post).parent().prev().text();
}
Note: This smells to me, your code is very much tied into the structure of the HTML this way. If you alter the HTML, chances are your javascript will break.
I have copied your code into my own HTML document, and confirmed that the jquery method calls above output the desired result. If you are not, then something is different with your source HTML and the source that you posted, or your jquery functions differ from the ones stated in this answer :)

your onclick attribute is wrong,because onclick accept javascript,so the value could be support js,then onclick="quote('p#p50')".
function quote(post) {
var subject = $(post).text();
var user=$(post).parent().prev('a').text();
console.log('posted '+subject+' by '+user);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
SOMEUSERNAME
<div class="col s9">
<p id="p_50">Some message</p>
<br>
<br>
<span class="forumtools">
<strong>
<a onclick="quote('p#p_50')">Quote</a>
</strong>
<span class="right">Written SOMEDATE</span>
</span>
</div>

jQuery find closest

I'm trying to get the a href of an list item.
HTML
<div class="popup" style="display: none;">
<div class="product">
<div class="photo">
<a href="" class="sendkleur" id="link69"> <!-- href im trying to reach -->
<img id="product-collection-image-69" src="" alt="Test kleur" class="popup-image69">
</a>
</div>
<a href="" class="sendkleur" id="link69">
<strong>Test kleur</strong>
</a>
<span class="swatchLabel-category">Kleur:</span>
<p class="float-clearer"></p>
<div class="swatch-category-container" style="clear:both;" id="ul-attribute137-69">
<img onclick="listSwitcher();" src="" id="a137-32" class="swatch-category" alt="Beige" width="12px" height="12px" title="Beige">
<img onclick="listSwitcher();" src="" id="a137-36" class="swatch-category" alt="Zwart" width="12px" height="12px" title="Zwart">
</div>
<p class="float-clearer"></p>
</div>
</div>
There are multiple popups on the site and thats what makes it difficult. At first I used this code
var link = jQuery('.photo').find('a')[0].getAttribute("href");
But this ofcourse only returns the href of the first popup. Then I tried this code:
var link = jQuery('.photo').closest('a').attr("href");
But this returned undefined
Then I tried this:
var link = jQuery(this).closest('a').attr("href");
But that also returns undefined
Edit
Here is the whole jQuery code snippet
jQuery(document).ready(function(){
jQuery('.swatch-category-container img').click(function(){
var kleur = jQuery(this).attr('title');
var link = jQuery('.photo').find('a').attr("href");
console.log(link);
link += "?kleur="+kleur;
console.log(link);
jQuery('.photo').find('.sendkleur').attr("href", link);
});
});

Working from the .swatch-category-container img element, you can traverse the DOM to find the required a like this:
$('.swatch-category-container img').click(function() {
var link = $(this).closest('.popup').find('.photo a').prop('href');
// do something with link here...
});

If this is the .swatch-category-container img element then, the anchor is the previous to previous sibling of the ancestor swatch-category-container element
var link = jQuery(this).closest('.swatch-category-container').prev().prev().attr("href");

Since you said multiple popups, the idea would be like this.
1. Get all popups
2. From each popup in all popups
Get the photo href item
$('.popup').each(function() {
var hrefItem = $(this).find('.photo a').attr('href');
//Do your processing with href item
});

Javascript Selecting child element not working

i m working on adding a FB share button to all my posts.
so i wanted to use the sharer.php? method with all the parameter retrieved from the post.
So my blog structure
<div id='postwrapper'>
<div id='title'>
hello</a>
</div>
<div id='da'>
<span>Posted on </span>
<span class='divider'></span>
<span>By</span>
</div>
<div class='post_content'>$row['post'] gud day</div>
<div id='post_footer'>
<a href=viewpost.php>Continue reading</a>
<a href='#' onClick='fbshare(this)'>Insert text or an image here.</a>
</div>
</div>
My javascript for fbshare function (not complete).
function fbshare(fb) {
var p1 = fb.parentNode;
var p2 = p1.parentNode;
var title = p2.getElementById("title").innerHTML;
alert(title);
}
Everytime i try this it says undefined is not a function

getElementById is a function of the document. Assuming you have more than one post on the page (ids must by unique), try using a class instead:
<div class='title'>
And using getElementsByClassName:
var title = p2.getElementsByClassName("title")[0].innerHTML;

Multiple element, same class, get value of one element - jquery

I have this multiple elements with the same class.
<div class="test-container">
<a class="dup-class">
Get Value
</a>
<div class="product-list-col">
1
</div>
</div>
<div class="test-container">
<a class="dup-class">
Get Value
</a>
<div class="product-list-col">
2
</div>
</div>
<div class="test-container">
<a class="dup-class">
Get Value
</a>
<div class="product-list-col">
3
</div>
</div>
If I click the the <a> tag on the first div, it should alert the value of .product-list-col value which is 1
if I click the second div of anchor tag, it should alert 2
here's the code for it
$(".dup-class").on('click', function() {
cont = $(this + " .product-list-col").text();
alert(cont);
});
Any solution for this stuff?
Here's the jsfiddle of it: http://jsfiddle.net/Vigiliance/PLeDs/3/

You could use siblings(), the reason why your code doesn't work is because it's selecting all .product-list-col
$(".dup-class").on('click', function () {
cont = $(this).siblings('.product-list-col').text();
alert(cont);
});
or use .next()
$(".dup-class").on('click', function () {
cont = $(this).next('.product-list-col').text();
alert(cont);
});

do this:
$(".dup-class").on('click', function() {
cont = $(this).next().text(); // this is the line where change done
alert(cont);
});
