How to select only headers within a class

I am trying to hide the div if you click only on the header. But my filter does not seem to work. I get the intended function wherever I click on the div. I want to restrict this to only when you click on the header.
<div class="post" onclick="updatenext()">
<h2>Item3</h2>
</div>
<div class="post" onclick="updatenext()">
<h2>Item4</h2>
</div>
<script>
var index=0;
$(".post").hide();
$(".post").eq(0).show();
// Tried this too: $(".post").filter(":header")....
$(":header.post").on("click",
function () {
index=$(this).index();
//console.log($(this).index());
$(this).hide();
$(".post").eq(index).show();
}
);
</script>
I expect the click to work only when clicking on the header element within each div.

Try using only jQuery for the event listener, like this:
<div class="post">
<h2 onclick="updatenext()">Item3</h2>
</div>
<div class="post">
<h2 onclick="updatenext()">Item4</h2>
</div>
<script>
var index = 0;
$(".post").hide();
$(".post").eq(0).show();
$("h2").on("click", function () {
index = $(this).parent().index();
$(this).parent().hide();
$(".post").eq(index).show();
});
</script>

Add external link to an <a> element inside a Click Event Listener Div

I'm having trouble adding a link to a button inside a card. the card is wrapped in a div element which when clicked automatically expands and closes.
Is there anyway to remove this functionality just when clicking on the details button? So it acts as a normal link?
Here is the code:
https://codepen.io/candroo/pen/wKEwRL
Card HTML:
<div class="card">
<div class="card__image-holder">
<img
class="card__image"
src="https://source.unsplash.com/300x225/?wave"
alt="wave"
/>
</div>
<div class="card-title">
<a href="#" class="toggle-info btn">
<span class="left"></span>
<span class="right"></span>
</a>
<h2>
Card title
<small>Image from unsplash.com</small>
</h2>
</div>
<div class="card-flap flap1">
<div class="card-description">
This grid is an attempt to make something nice that works on touch
devices. Ignoring hover states when they're not available etc.
</div>
<div class="card-flap flap2">
<div class="card-actions">
Read more
</div>
</div>
</div>
</div>
JS:
$(document).ready(function () {
var zindex = 10;
$("div.card").click(function (e) {
e.preventDefault();
var isShowing = false;
if ($(this).hasClass("show")) {
isShowing = true;
}
if ($("div.cards").hasClass("showing")) {
// a card is already in view
$("div.card.show").removeClass("show");
if (isShowing) {
// this card was showing - reset the grid
$("div.cards").removeClass("showing");
} else {
// this card isn't showing - get in with it
$(this).css({ zIndex: zindex }).addClass("show");
}
zindex++;
} else {
// no cards in view
$("div.cards").addClass("showing");
$(this).css({ zIndex: zindex }).addClass("show");
zindex++;
}
});
});

You can check the target of the event and see if it is an <a> using is()
Something like:
$("div.card").click(function (e) {
// only run when not an `<a>`
if(!$(e.target).is('a')){
e.preventDefault();
//the rest of your code
....
}
});

I don't know Jquery but with javascript you can do this inside your code:
const links = document.querySelectorAll('.btn');
links.forEach(link => link.addEventListener('click', (e)=>e.stopPropagation()))

use Jquery to click hyperlink

I am trying to create a jquery to click a hyperlink but nothing seems to be working.
HTML
<main id="main" class="main-content">
<div class="container">
<div class="warning" role="alert">
no avail
Show all
</div>
what I was trying
$(".warning a").click()
Any suggestions?

Note that jQuery-initiated "click" events will fire the event but will not cause navigation to occur.
Instead you can read the link's HREF attribute and directly set the window location:
// The click event:
$('a').on("click", function() {
console.log("Click event fired");
})
var demo1 = function() {
// This will trigger the click event, but will not navigate.
$(".warning a").click()
}
var demo2 = function() {
// This will navigate but will not trigger the click event. (If you need both to happen, trigger the click event first, and consider delaying the window location update if necessary.)
var url = $(".warning a").attr("href")
window.location = url;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<main id="main" class="main-content">
<div class="container">
<div class="warning" role="alert">
Show all
</div>
</div>
</main>
<!-- for demo: -->
<button onclick="demo1()">Won't work</button>
<button onclick="demo2()">Will work</button>

jQuery's .click() (without arguments) is a shortcut for .trigger("click"):
function(a,c) {
return arguments.length > 0 ? this.on(b, null, a, c) : this.trigger(b)
}
Therefore, it will not actually click the element, but just call the click event handlers attached to it, as you can see here:
const $link = $("a");
$link.on("click", () => {
console.log("Clicked? Not really...");
});
$link.click();
$link.trigger("click");
Show all
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
You need to get a reference to the actual DOM element and then call HTMLElement.click() on that:
$("a")[0].click();
Show all
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

You can user the vanilla click method:
document.querySelector('.warning > a').click()
// equivalent jquery
//$('.warning > a')[0].click()
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="warning" role="alert">
no avail
Show all
</div>

Whenever you select div class with hyperlink there you get array because you can have multiple hyperlinks so you need to add somthing like below
Code
$('.warning a')[0].click();
For reference link
Get working example for click event

If I need to redirect, I typically use window.location.href
window.location.href=$(".warning a").attr('href');

Only fire one onmouseover when hovering over multiple elements

I'd like to have basic code like the following:
<span onmouseover="alert('hi')">Hello, <span onmouseover="alert('hello')">this</span> is a test</span>
However, I'd like to keep it from firing both of these events if both are being hovered over; e.g. if I hover over "this" it should fire only its event and alert "hello." How can I do this?
Thank you in advance!

$(".container").hover(function(){
alert($(this).attr("id"));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<span class="container" id="hi">
Hello,
</span>
<span class="container" id="hello">
this
</span>
<span class="container" id="hi">
is a test
</span>

I am going to assume that the overlapping elements are not the same size. I.e one is bigger than the other.
HTML and inline js:
<span class="container" id="hi">
Hello,
</span>
<span class="container " id="hello">
this </span>
<script>
var hello =
document.getElementById("hello");
var this =
document.getElementById
("this");
hello.addEventListener("click
",pop("hello"));
this.addEventListener("click",pop(" hi");
function pop(string) {
window.alert(string);
}
<\script>
That being said very little is mentioned about the nature of the elements this and hello. Op plz show your CSS and update ques

Here's the relevant portion of what I ended up using. I used JQuery.
var mouseHovered = function(element) {
//get all hovered spans
var hoveredElements = $("span:hover");
//get the element with the smallest text
var smallestElement;
for(var i=0; i<hoveredElements.length; i++) if(!smallestElement || hoveredElements[i].textContent.length < smallestElement.textContent.length) smallestElement = hoveredElements[i];
//if this is the smallest text in the elements
if(element == smallestElement) {
//log the text
console.log(element.textContent);
}
}

You need to prevent Event bubbling when you hover/click on inner span.
This can be done using event.stopPropagation().
Look at two solutions provided at this JSFiddle.
Solution 1 - Use of e.stopPropagation() in the handler function innerSpan().
Solution 2 - Use of event.stopPropagation() in inline onclick event.
<span onclick="alert('Outer span');">
Outer
<span onclick="event.stopPropagation(); alert('Inner span');">
Inner
</span>
</span>

Find sibling with Javascript and Hammer.js

I have made a simple system which detects double taps. I want to show a heart icon when someone double taps on an image, just like on Instagram.
This is what my code looks right now:
var elements = document.getElementsByClassName('snap_img');
[].slice.call(elements).forEach(function(element) {
var hammertime = new Hammer(element),
img_src = element.getAttribute('src');
hammertime.on('doubletap', function(event) {
alert(img_src); // this is to test if doubletap works
// Some javascript to show the heart icon
});
});
This is what the HTML looks like:
<div class="snap_item">
<div class="snap_item_following_info">
<img class="snap_item_following_img" src="res/stat/img/user/profile/small/1.fw.png" alt="#JohnDoe" />
<a class="snap_item_following_name" href="#">#JohnDoe</a>
<div class="snap_too">
</div>
</div>
<img class="snap_img" src="res/stat/img/user/snap/43/2.fw.png" alt="#ErolSimsir" />
<div class="like_heart"></div>
<div class="snap_info">
<div class="snap_text">
LA is the shit...
<a class="snap_text_hashtah" href="#">#LA_city_trip</a>
</div>
<div class="snap_sub_info">
<span class="snap_time">56 minutes ago</span>
<div class="like inactive_like">
<div class="like_icon"></div>
<div class="like_no_active">5477</div>
</div>
</div>
</div>
</div>
So when the element 'snap_img' is double tapped, I need to get the element 'like_heart' which is one line below the snap_img element. How do I get that sibling element and fade it in with JQuery?

Like this
[].slice.call(elements).forEach(function(element) {
var hammertime = new Hammer(element),
img_src = element.getAttribute('src');
hammertime.on('doubletap', function(event) {
alert(img_src); // this is to test if doubletap works
$(element).next().text('♥').hide().fadeIn();
});
});
P.S. I've added that heart text, since the sibling was empty.

On the event handler, i would do $(element).parent().find('.like_heart').fadeIn(); So the code is not dependant on the element ordering.
(To clarify to selector: take the parent element which is the div.snap_item and find an element with class like-heart inside it)
