Javascript show and hide function - javascript

I am trying to do the show/hide function with some containers and text.
When i click on a certain container I want a paragraph to hide. At the moment I am trying to work out when I click the "left" container, the paragraph "barbertext" to disappear.
<p class="hairtext" style="color:red">We are Thairapy, an independent hair <br> and beauty Salon located in the heart<br> of Exeter. At Thairapy, we care about<br> our clients and our main aim is to go<br> that extra mile and look after every <br> one of our happy customers.</p>
<p class="beautytext" style="color:red">Our beautician, Shail Dutt has over<br> 10 years of experience within the beauty<br> industry. Shail is a very dedicated and<br> passionate person, she strives to make<br> her clients feel loved and special. </p>
<p class="barbertext" style="color:red">A decent Mens haircut needn't cost the<br>Earth. We offer top quality Men's haircuts<br> from £7. </p>
<div class="container" id= "left" >
<h1 style="color:white"><a>HAIR</a></h1>
</div>
<div class= "container" id= "center">
<h1 style="color:white"><a>BEAUTY<a/></h1>
</div>
<div class="container" id= "right">
<h1 style="color:white"><a>BARBERS</a></h1>
</div>
</div>
The Javascript that I am working with is this:
<script>
$(document).ready(function(){
$("#hairtext").click(function(){
$("barbertext").hide();
});
$("#hairtext").click(function(){
$("barbertext").show();
});
});
</script>
If anyone could help I would be most appreciated.

You bind both handlers to the same element, so you hide and show each time you click.
Try toggle() so that it alternates between hide/show
$(document).ready(function(){
$(".hairtext").click(function(){
$(".barbertext").toggle();
});
});
(needed to add . to the barbertext selector, and . for the hairtext. # is used for ids)

I have made the following fiddle that should do what you need http://jsfiddle.net/Lyd9hgh2/
$(document).ready(function(){
var hidden= false;
$("#left").click(function(){
if(hidden){
$(".barbertext").show();
hidden = false;
}else
{
$(".barbertext").hide();
hidden = true;
}
});
});

You did wrong with your selector:
$(".barbertext")
I am not sure about what you want, but it seems as you want when the user click on the container, a associated div is showed/ hide.
I created a fiddle for that:
http://jsfiddle.net/BenoitNgo/0yL02nop/6/

Corrected the existing code: (as per your need - when I click the "left" container, the paragraph "barbertext" to disappear)
<script>
$(document).ready(function(){
$("#left").click(function(){
$(".barbertext").hide();
});
$("#left").click(function(){
$(".barbertext").show();
});
});
</script>
Improvments:
You can use Ids for containers and paragraphs both for performance
You can use jquery toggle function if you want a show/hide behavior on container click

How to toggle specific divs with jquery

Okay so I have a very limited amount of knowledge with this and I can not find my answer anywhere. What I am trying to do is create multiple buttons that toggle information. So when the first toggle is clicked div 1 is toggled, when i click the second toggle div two opens and preferably div 1 closes. My code is very basic I am very new to this. Right now no matter what values I input into the toggle area both divs close. Thank you and I hope this makes sense.
Here is my code:
<script>
$(document).ready(function(){
$("button").click(function(){
$("div.house").toggle();
});
});
</script>
<button>Toggle</button>
<div class="house">
<p>SAMPLE TEXT ETC...</p>
</div>
<button>Toggle</button>
<div class="tumble-by">
<p>SAMPLE TEXT ETC...</p>
</div>
You can select the next sibling:
$("button").click(function(){
$(this).next().toggle();
});
In the above code, JavaScript this keyword refers to the clicked element. $(this) creates a jQuery collection and .next() method selects the very next sibling of the collection's element.
I agree too, that first you need to hide all divs:
$("button").click(function () {
$('div').hide();
$(this).next().toggle();
});
<script>
$(document).ready(function () {
$(document).on("click", ".js-toggle__button", function (e) {
$(".js-toggle__text").hide();
$(this).next(".js-toggle__text").show();
});
});
</script>
<button class="toggle__button js-toggle__button">Toggle</button>
<div class="toggle__text js-toggle__text">
<p>SAMPLE TEXT 1 ETC...</p>
</div>
<button class="toggle__button js-toggle__button">Toggle</button>
<div class="toggle__text js-toggle__text">
<p>SAMPLE TEXT 2 ETC...</p>
</div>
It's better to use uniquely defined identifiers when you accessing elements from JS (and don't use them for CSS — use separate names).
Your HTML code some day can be changed dramatically and JS will work anyway because it depends on identifiers but not on structure or on tag names.

Selecting only one div of entire css class in jQuery

my goal is to show an overlay on a div when that div is hovered on. The normal div is called .circleBase.type1 and the overlay is circleBase.overlay. I have multiple of these divs on my page. When I hover over one .cirlceBase.type1, overlays show on every .circleBase.type1. How do I prevent this?
Here is some code:
HTML
<div class="circleBase type1">
<p class="hidetext">Lorem ipsum</p>
<hr size="10">
<strong class="gray hidetext">gdroel</strong>
</div>
<div class="circleBase overlay">
<p class="date">11/12/14</p>
</div>
and jQuery
$(document).ready(function(){
$('.overlay').hide();
$('.date').hide();
$(".circleBase.type1").mouseenter(function(){
$(".overlay").fadeIn("fast");
$('.date').show();
$('.hidetext').hide();
});
$(".overlay").mouseleave(function(){
$(this).fadeOut("fast");
$('.date').hide();
$('.hidetext').show();
});
});
Use $(this) to get current element reference and do like this:
$(".circleBase.type1").mouseenter(function(){
$(this).next(".overlay").fadeIn("fast");
$(this).next(".overlay").find('.date').show();
$(this).find('.hidetext').hide();
});
and:
$(".overlay").mouseleave(function(){
$(this).fadeOut("fast");
$(this).find('.date').hide();
$(this).prev(".circleBase").find('.hidetext').show();
});
usually when I want to target something specific you just give it an ID.
ID's play better in JavaScript than classes.
If you had a specific container, using the container as your starting point is a good route as well
$('#container').find('.something.type1').doSomething();
This is much more efficient for jquery, because it only searches .something.type1 inside of #container.
Well I'm not sure exactly what you're looking to do, but it looks like you want to replace content in some kind of circle with a hover text, but with a fade. To do that you'll have to add some CSS and it would be best to change your HTML structure too.
The HTML should look like this:
<div class="circleContainer">
<div class="circleBase">
<p>Lorem ipsum</p>
<hr>
<strong class="gray">gdroel</strong>
</div>
<div class="overlay" style="display: none;">
<p class="date">11/12/14</p>
</div>
</div>
so your js can look like this:
$(function(){
$(".circleContainer").mouseenter(function(){
$(this).find(".overlay")
$(this).find('.circleBase').hide();
});
$(".circleContainer").mouseleave(function(){
$(this).find('.circleBase').show();
$(this).find(".overlay").hide();
});
});
Here's a working solution that includes some CSS to make it nice. Try taking it out and running it, you'll see the problems right away.

Loading hidden HTML content into DIV from anchor link

I am trying to create a group of links or buttons that will change the content of a div
<p><button>EMPLOYEE NAME HERE</button></p>
<p><button>EMPLOYEE NAME HERE</button></p>
<p><button>EMPLOYEE NAME HERE</button></p>
<p><button>EMPLOYEE NAME HERE</button></p>
Each employee has a different image and description but each div are the same size, the first employee will be shown by default as so to have no empty space but when the other 3 are selected the div is filled with the respective div according to it, then you can cycle through the profiles as you wish. Here is my div structure
<div id="employee">
</div>
<div id="employee1">
</div>
<div id="employee2">
</div>
<div id="employee3">
</div>
<div id="employee4">
</div>
Here is the javascript im trying to use
<script type="text/javascript" charset="utf-8">
$('button').bind('click', function() {
$('div#employee').html($('div#employee' + ($(this).index()+1)).html());
});
</script>
All the help i can get would be really appreciated, im not that great at java script and really need a hand with this. Im not sure i explained myself very well but i did try.
Just to confirm, all the divs are hidden until the button is pressed, then the div for that employee will appear, except the first profile which will appear by default on load.
Thanks for your help in advance.

Here's a pretty simplified example. It may or may not be the most efficient, but it should do what you want. This is assuming that you're pre-loading all of the content into the divs, but just hiding it at the beginning. If you are wanting to dynamically load the content, then you'll want to use some ajax
HTML
<p><button id="button1">EMPLOYEE One</button></p>
<p><button id="button2">EMPLOYEE Two</button></p>
<p><button id="button3">EMPLOYEE Three</button></p>
<p><button id="button4">EMPLOYEE Four</button></p>
<p><button id="button5">EMPLOYEE Five</button></p>
<br/><br/>
<div id="employee1" class="employeeInfo">
Employee1 is a good employee
</div>
<div id="employee2" class="employeeInfo">
Emloyee2 is an alright employee
</div>
<div id="employee3" class="employeeInfo">
Emloyee3 is the best employee ever!
</div>
<div id="employee4" class="employeeInfo">
Employee4 is not a very good employee
</div>
<div id="employee5" class="employeeInfo">
Employee5 is about to be fired
</div>
Javascript
$(function(){
$("#employee1").show();
$("button").on("click", function(){
$(".employeeInfo").hide();
$("#employee"+String($(this).attr("id").substring(6))).show();
// OR if you don't want to have to give IDs to the buttons
// $("#employee"+String($("button").index($(this))+1)).show();
});
});
CSS
.employeeInfo {
display: none;
}

jQuery: get a reference to a specific element without using id

I'm tinkering a bit with jquery to show a hidden div when a link is clicked. This should be fairly simple, but there's a flaw to it in this case. I have the following markup:
<div class="first-row">
<div class="week">
<p>Uge 2</p>
<p>(08-01-11)</p>
</div>
<div class="destination">
<p>Les Menuires</p>
<p>(Frankrig)</p>
</div>
<div class="days">4</div>
<div class="transport">Bil</div>
<div class="lift-card">3 dage</div>
<div class="accommodation">
<p><a class="show-info" href="#">Hotel Christelles (halvpension)</a></p>
<p>4-pers. værelse m. bad/toilet</p>
</div>
<div class="order">
<p>2149,-</p>
<p class="old-price">2249,-</p>
</div>
<div class="hotel-info">
<!-- The div I want to display on click -->
</div>
</div>
When I click the "show-info" link I want the "hotel-info" div to display.
My backend devs don't want me to use ids (don't ask me why..) and the above markup is used over and over again to display data. Therefore I need to be able to access the "hotel-info" div in the "first-row" div where the link is clicked.
I've tried to do something like:
$(document).ready(function() {
$('.show-info').click(function() {
var parentElement = $(this).parent().parent();
var lastElementOfParent = parentElement.find(".show-hotel");
lastElementOfParent.show();
});
});
But without a result :-/ Is this possible at all?
Any help is greatly appreciated!
Thanks a lot in advance!
Try this:
$('.show-info').click(function() {
$(this).closest('.accommodation').siblings('.hotel-info').show();
});
Even better imo, as it would be independent from where the link is in a row, if every "row div" has the same class (I assume only the first one has class first-row), you can do:
$(this).closest('.row-class').find('.hotel-info').show();
Reference: .closest, .siblings
Explanation why your code does not work:
$(this).parent().parent();
gives you the div with class .accommodation and this one has no descendant with class .hotel-info.
It is not a good idea to use this kind of traversal for more than one level anyway. If the structure is changed a bit, your code will break. Always try to use methods that won't break on structure changes.
You're right in not using an ID element to find the DIV you want :)
Use closest and nextAll
Live demo here : http://jsfiddle.net/jomanlk/xTWzn/
$('.show-info').click(function(){
$(this).closest('.accommodation').nextAll('.hotel-info').toggle();
});

onclick alert jquery html javascript

I have a page so far with:
<div id="x1">Text paragraph 1<link here></div>
<div id="x2">Text paragraph 2<link here></div>
<div id="x3">Text paragraph 3<link here></div>
Where link here is like
google
What I am trying to do is add a link to the bottom of each paragraph of text so that when it is clicked it displays an alert with the div id of that text block.
So for example, if someone clicks on the link at the bottom of text paragraph 2, then they will get an alert saying "x2".
So far, I have only been able to think of a way involving an onclick event for each link in each div. But with 100 paragraphs this could become quite a lot and is messy code.
like
$('#x1').onclick(function(){
alert('x1');
});
How can I do this better?
The page is generated with php so I could put the div id's anywhere in that text block area (even make a new div around the link if required)...
EDIT - Many good answers, I don't know which to pick as best. I actually ended up using Loongawas for my purpose as its easy to make for my beginner level in php.
<div id='a1'>This text <a href="" onclick=tomato(1)>test</a>
</div>
<div id='a2'>This text <a href="" onclick=tomato(2)>test</a>
</div>
<div id='a3'>This text <a href="" onclick=tomato(3)>test</a>
</div>
and
function tomato(test){
alert(test);
};
Some of the others are incredibly interesting as they use higher functions. I'm going to spend the rest of the day looking into them. Thanks to all.
use jQuery's live or delegate functions:
$('div a').live('click', function(ev){
alert($(this).closest('div').attr('id'));
});
The benefit to the live/delegate functions is that there's actually only a single event on the entire page for this (as opposed to one event per link). If you add more links dynamically, this still works without having to attach more events.
The difference between live and delegate is that delegate is specific to a part of the page. If, for instance, you wrapped all of these DIVs in another div, the call would look like:
$('#wrapperDiv').delegate('a', 'click', function(ev){ ...
The advantage to this is that the internal jQuery code that checks to see if the click matches the selector only runs on clicks inside of #wrapperDiv instead of clicks anywhere on the page.
You could make a javascript function that takes a variable and then pass the paragraph number to the function. If the paragraph was number two you could call
myfunction(2);
or is the number not the problem?
$('#x1, #x2, #x3').click(function(){
alert($(this).parents().attr("id"));
});
EDIT:
Better version:
HTML:
<div class="x">Text paragraph 1<link here></div>
<div class="x">Text paragraph 2<link here></div>
<div class="x">Text paragraph 3<link here></div>
$('.x a').click(function(){
alert($(this).parents().attr("id"));
});
Have you considered using a class to name them all as opposed to explicit ids?
<div class="x">Text paragraph 1<link here></div>
<div class="x">Text paragraph 2<link here></div>
<div class="x">Text paragraph 3<link here></div>
so then you would be able to use a single click event for all of them?
$(".x a").click()
{
//Use $(this) to refer to the clicked item.
alert($(this).parents().attr("id"));
});
$('.myDivs').click(function(){
alert($(this).parent().attr("id"));
});
Or select the divs in some other way:
$('#x1').parent().children('div').click(...);
Something along these lines should work:
<div id="x1">Text paragraph 1 <a href='google.com'>google.com</a></div>
<div id="x2">Text paragraph 2 <a href='google.com'>google.com</a></div>
<div id="x3">Text paragraph 3 <a href='google.com'>google.com</a></div>
<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js'></script>
<script>
$('a').click(function() {
alert($(this).parent().attr('id'))
return false
})
</script>
Add a class to each div, so you can select all of 'em at once.
<div id="x1" class="x">Text paragraph 1 <a>Click</a></div>
<div id="x2" class="x">Text paragraph 2 <a>Click</a></div>
<div id="x3" class="x">Text paragraph 3 <a>Click</a></div>
Then you can do:
$('div.x a').live('click', function(e){
e.preventDefault();
alert($(this).closest('div.x').attr('id'));
});
http://jsfiddle.net/VGh3X/1/
A better approach to this is to make all of the clickable areas share something in common that you can use as a selector. For example, if all of the clickable divs had class='click', you'd be able to select them all using $('.click') and bind to that.
$('.click a').bind('click', function() {
var div = this.closest('.click');
alert(div.attr('id'));
return false;
});
$(document).ready(function() {
var links = $("div[id^='x'] a"); //get the a tags
$.each(links, function(i,v) {
$(v).click(function() { //bind on click
alert(v.parentNode.id); //alert div id
return false; // stop
});
});
});
