Hide and show elements using one function and number argument - javascript

<script>
function gato(n){
if(n == 1){
document.getElementById("A" + n).style.display="block";
}
if(n == 2){
document.getElementById("B" + n).style.display="block";
}
}
</script>
<body style="width:auto">
<div class="wrapper">
<div class="cuadro1" onClick="gato(1)">
<div style="display:none" id="A1" onClick="gato(2)"> <img src="images/x.png" alt=""/> </div>
<div style="display:none" id="B2" onClick="gato(1)"> <img src="images/o.png" alt=""/> </div>
</div>
</div>
What is supposed to happen is: when you click the div class cuadro1 then the div with id A1 is going to be displayed, then when you click that div(id A1) then the div id B2 is going to be displayed. then you can click that div id B2 and go back to div id A1.
I believe the problem lies in that you have to un-display id A before displaying id B2 with document.getElementById("B2").style.display="none"; but I just can't get it to work.

Because you're a beginner, I also made changes to your design:
HTML
<div class="wrapper">
<div class="cuadro1" onClick="gato(1)">
<h1>Click here to show #1</h1>
</div>
<div>
<div style="display:none" id="A1" onClick="gato(2, this)"> <h2>DIV#1</h2> </div>
<div style="display:none" id="A2" onClick="gato(1, this)"> <h2>DIV#2</h2> </div>
</div>
</div>
I put #A1 and #A2 from class="cuadro1". This is because click events bubble from the clicked element to his parents. So when anyone clicks A1 or A2 the cuadro1 is also clicked. That means A1 would be allways shown.
I also renamed B2 to A2 for convenience.
Javascript
functiongato(n, clickedDiv) {
// Hide the div that was clicked
if(clickedDiv!=null)
clickedDiv.style.display = "none";
// Change whatever ID is given
document.getElementById("A" + n).style.display="block";
}
To save ourselves time, we can use this refference in onclick to hide div that was clicked. The clickedDiv!=null allows you to pass nothing if you don't want to hide clicked div. Since names are now A1 and A2, if statement is no longer needed.
Here's a test: https://jsfiddle.net/1zojdvt0/

Here is one way to accomplish this, using css. Add/remove a class from your elements and use CSS styling based on class to hide the div contents.
Javascript:
function gato(n, clicked){
if(clicked) {
clicked.classList.add('hidden');
}
var showElem = (n == 1 ? "A1" : "B2");
document.getElementById(showElem).classList.remove('hidden');
}
HTML:
<div class="wrapper">
<div class="cuadro1" onClick="gato(1, null)">Click Me
<div class="hidden" id="A1" onClick="gato(2, this)">A1 </div>
<div class="hidden" id="B2" onClick="gato(1, this)">B2 </div>
</div>
</div>
CSS:
.hidden { display:none;}

javascript toggle showing and hiding several div elements

I have two divs on a page (id's MAY and JUNE) and two buttons on the page. The page startes off by showing the May div, with the June div hidden using css display: none
I am trying to create the correct javascript that will toggle between the two of them, but (after searching on here) I can only manage to get one to work.
Codepen showing issue is https://codepen.io/billteale/pen/zwBBez
<a href="#" id="button" >MAY</a>
<a href="#" id="button" >JUNE</a>
<!-- first div, shows on page load -->
<div id="MAY">
<div style="background-color: lightgrey"><h1 style="padding: 5px"><strong>May 2017</strong></h1>
</div>
<!-- second div, hidden originally -->
<div class="hidden" id="JUNE">
<div style="background-color: lightgrey"><h1 style="padding: 5px"><strong>June 2017</strong></h1>
</div>
...and the current js is
var button = document.getElementById('button'); // Assumes element with id='button'
button.onclick = function() {
var div = document.getElementById('MAY');
if (div.style.display !== 'none') {
div.style.display = 'none';
}
else {
div.style.display = 'block';
}
};
Eventually I will have four or more divs to toggle between, with each button showing its relevant div, and hiding the others.
Can anybody tell me how to add to the code I have here to make this work for multiple elements?
It can be done by setting the div id's in the anchor tag's href attribute, and showing the corresponding div while hiding the rest. It can be done for any number of div's with no extra script, Just add the new div id to the new anchor tags href. You should give a common class to all the div's like month to select them all.
$("a.btn").click(function() {
var id = $(this).attr("href");
$("div.month:visible").hide();
$(id).show();
});
.hidden {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
MAY
JUNE
<!-- first div, shows on page load -->
<div id="MAY" class="month">
<div style="background-color: lightgrey">
<h1 style="padding: 5px"><strong>May 2017</strong></h1>
</div>
</div>
<!-- second div, hidden originally -->
<div class="month hidden" id="JUNE">
<div style="background-color: lightgrey">
<h1 style="padding: 5px"><strong>June 2017</strong></h1>
</div>
</div>
First you add a "div-toggle" class to each one of the divs you want to toggle. After that, you bind click events on your buttons, firing a function which takes an identifier as argument.
The function will run through your divs and set the one that has the argument id as visible, and hide the others.
This way you can add more divs to be toggled. You just have to mark them with the "div-toggle" class, set their id's and create their respective buttons.
var divs = document.getElementsByClassName('div-toggle');
function toggle(id) {
for (var i = 0; i < divs.length; i++) {
var div = divs[i];
if (div.id == id)
div.style.display = 'block';
else
div.style.display = 'none';
}
}
<a href="#" onclick="toggle('MAY')" >MAY</a>
<a href="#" onclick="toggle('JUNE')" >JUNE</a>
<!-- first div, shows on page load -->
<div class="div-toggle" style="display:block;" id="MAY">
<div style="background-color: lightgrey">
<h1 style="padding: 5px"><strong>May 2017</strong></h1>
</div>
</div>
<!-- second div, hidden originally -->
<div class="div-toggle" style="display:none;" id="JUNE">
<div style="background-color: lightgrey">
<h1 style="padding: 5px"><strong>June 2017</strong></h1>
</div>
</div>
div.style.visibility = "hidden"
this will completely hide your div. I'm pretty sure this is what you are asking for
also instead of that you can make a separate function and add o'clock to div
<div onclick="nameoffunction()"></div>
the function can take in a parameter and each div on click function can have the parameter of its id
Your div were messed up! The snippet is working now with the help of jQuery.
$("#JUNE").hide();
$("#MAY").show();
$('#button-may').on("click", function() {
$("#JUNE").hide();
$("#MAY").show();
});
$('#button-june').on("click", function() {
$("#JUNE").show();
$("#MAY").hide();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
MAY

<!-- first div, shows on page load -->
<div id="MAY">
<div style="background-color: lightgrey">
<h1 style="padding: 5px"><strong>May 2017</strong></h1>
</div>
</div>
<!-- second div, hidden originally -->
<div class="hidden" id="JUNE">

how to create new bullent icon inside a div element according to no of div element?

I want to create bullet icon dynamically according to no of div.
for example if i have 2 div slider, so i want to create 2 bullet icon inside other div if div count is 0 bullet should be display none.
I want something like this
<div class="mainslider">
<div class="slider"><img src="abc.jpg"></div>
<div class="slider"><img src="xyz.jpg"></div>
</div>
<div class="bullet">
•
•
</div>
basically i want to create bullet icon dynamically according to no of slider div.
Thanks in advance
You could count how many div with "slider" class there are, then cycle this number to append new a with bullets to div with "bullet" class.
$(function() {
for (var i = 1; i <= $(".slider").size(); i++) {
$("<a></a>").attr("href", "#" + i).html("•").appendTo(".bullet");
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="mainslider">
<div class="slider">
<img src="abc.jpg">
</div>
<div class="slider">
<img src="xyz.jpg">
</div>
</div>
<div class="bullet">
</div>

Show / Hide child DIVs on click on the main DIV, similar to spoiler (pure JS)

I have 20 rows of DIVs. The initial state hides all spoilers and is like below (I show the first 3 rows here):
<div class="main" onClick="showHide()">
some text 1
<div class="spoiler hide">spoiler</div>
</div>
<div class="main" onClick="showHide()">
some text 2
<div class="spoiler hide">spoiler 2</div>
</div>
<div class="main" onClick="showHide()">
some text 3
<div class="spoiler hide">spoiler 3</div>
</div>
etc..
CSS:
<style>
.main{background:silver;padding:1em;margin-bottom:1em}
.hide{display:none}
.show{display:block}
</style>
My goal is to manipulate/change the spoiler classes after user clicks on the "main" DIV. That is, after clicking on one of the "main" DIVs the "spoiler hide" class should automatically change to "spoiler show" so that the text is shown. And when user clicks on another "main" DIV, all 'spoiler show' classes should change to 'spoiler hide' and only the currently clicked "main" DIV should apply the 'spoiler show' class.
So it's basically like a toggle where only one (the last clicked) DIV shows the spoiler. I hope to find the simplest/fastest solution (JS in one line would work too).
I tried to use some JS function like below, but cannot make it work. I also read that 'document.querySelectorAll' might be used somehow.. I cannot use jQuery here.
<script>
function showHide() {
var e = document.getElementsByClassName('spoiler hide');
for(i=0; i<e.length; i++) {
e[i].className ='spoiler show';
}
}
</script>
Try this:
<script>
function showHide(sender) {
var e = sender.getElementsByClassName('spoiler hide');
for(i=0; i<e.length; i++)
{
e[i].className ='spoiler show';
}
}
</script>
<div class="main" onclick="showHide(this)">
some text 1
<div class="spoiler hide">spoiler</div>
</div>
<div class="main" onClick="showHide(this)">
some text 2
<div class="spoiler hide">spoiler 2</div>
</div>
<div class="main" onClick="showHide(this)">
some text 3
<div class="spoiler hide">spoiler 3</div>
</div>

On click not working after appending checkbox elements in jquery

The contact_container div holds contact children, within these children is a checkbox. I use ajax to append these children to the container. Once I append the html and click a childs checkbox. The .click does not recognize the newly added checkboxes, Only the children work on page load. Below are working samples of my HTML and Jquery.
Can you offer a solution so that the appended checkboxes are picked up when they are clicked? Thanks
Here is my HTML markup:
<div id="contact_container">
<div class="contact">
<div class="contact_checkbox">
<div class="checkbox_container">
<div class="checkbox">
<input class="testing_checkbox" type="checkbox" name="contacts[]" value="bf6b0049059ec8998601f8fe20acb68ecafe2d44">
</div>
</div>
</div>
<div class="contact_info">
<div class="contact_image">
<img src="image.jpg" width="50" height="50" alt="Profile Picture">
</div>
<div class="contact_name"><span>Caroline Airey</span>
</div>
</div>
</div>
</div>
<div id="x_message" class="inputdata" style="overflow: hidden; display: none;">
<label>Message:</label>
<span><textarea name="x_message" placeholder="Enter a message to send to your contact(s)"></textarea></span>
<div class="clear"></div>
<button class="form_button">Add Contact to Network</button>
</div>
Here is my Jquery:
$( ".checkbox" ).click(function() {
var checked = $('.testing_checkbox:checked').length;
$('#testing').val(checked);
if (checked > 0){
$('#x_message').show(1000);
}
else{
$('#x_message').hide(1000);
}
});
You will need the Parent reference to bind the element properly to jquery try this
$(parentObj).on("click",".checkbox",function() {
var checked = $('.testing_checkbox:checked').length;
$('#testing').val(checked);
if (checked > 0){
$('#x_message').show(1000);
}
else{
$('#x_message').hide(1000);
}
});
The parentObj is the div or the html element you've appended the html code with ajax call
Use this jQuery method instead:
$(".checkbox").on("click", function()
{
// Your code here
});
This will grab clicks from elements that are dynamically added to your page after it initially loads :)

How to display div with JavaScript depending on which image is clicked

I wish to display certain divs inside a main div dependent on which image is clicked. With out any decent knoweldge of Js or Jquery, I fail to do this without some assistance.
<form>
<input type="hidden" name="prod">
<div id="images">
<img id="one" src="http://lorempixel.com/200/200/">
<img id="two" src="http://lorempixel.com/201/200/ ">
<img id="three" src="http://lorempixel.com/203/200/ ">
<img id="four" src="http://lorempixel.com/204/200/ ">
</div>
</form>
<div id="description">
</div>
<div class="one">Brilliant</div>
<div class="two">Super</div>
<div class="tree">Amazing</div>
<div class="four">Excellent</div>
If the image which has id="one" is clicked, then display <div class="one">Brilliant</div> inside of the description div. Then ofcause if the second image is clicked, then display the the 'super' div inside the description div. I'd like to not have the descriptions visible until clicked, and only one div at a time to be shown.
The images are apart of a form because I need to forward the value of the id on the images to a variable.
Here is the script that does that.
$('#images').delegate('img', 'click', function () {
var $this = $(this);
// Clear formatting
$('#images img').removeClass('border-highlight');
// Highlight with coloured border
$this.addClass('border-highlight');
// Changes the value of the form field prod to the file name shown in the image.
$('[name="prod"]').val($this.attr('id').substring($this.attr('id').lastIndexOf('-') + 1));
//Alert for debugging simplicity
alert($('[name="prod"]').val());
});
Perhaps a function can be implemented into the current script?
Here is a fiddle, and it will all make sense of what I have as a whole currently.
Check out this fidde
You just need to add:
$('#description').html($('.' + $this.attr('id')).html());
At the bottom of your onclick function.
** You have a typo on the 3rd div with text(tree instead of three).
You can make it bit simple by adding the divs for description in div as I see no need to put the divs for description outside the description div and later adding it. You will need to hide all the divs we have in description div and show the one that is related to img being clicked.
