how to open specific div by class name onclick - javascript

I have many div with the class name dis
HTML:
<div class="dis">Content</div>
<div class="dis">Content</div>
<div class="dis">Content</div> and so on ...
And have many images:
<img src="icons/image1.png" class="admoicn" onclick="toggle_visibility('dis');" >
<img src="icons/image2.png" class="admoicn" onclick="toggle_visibility('dis');" >
<img src="icons/image3.png" class="admoicn" onclick="toggle_visibility('dis');" >
CSS:
.dis{
display:none;
width:100px;
height:100px;
}
javascript:
function toggle_visibility(id) {
var e = document.getElementsByClassName(id)[0];
if(e.style.display =="block"){
e.style.display ="none";
}
else{
e.style.display ="block";
}
}
Onclicking any image the specific div dis should be open, I mean onclicking third image3.png the third number of div dis should be open and close all opened dis div.
I think it's the array problem on javascript class and I don't know how to fix it. I'm very new to javascript.

You could add an argument to the toggle_visibility function:
<img src="icons/image1.png" class="admoicn" onclick="toggle_visibility('dis', 0);" >
<img src="icons/image2.png" class="admoicn" onclick="toggle_visibility('dis', 1);" >
<img src="icons/image3.png" class="admoicn" onclick="toggle_visibility('dis', 2);" >
And use it as index to the array:
function toggle_visibility(id, index) { // added index here
// close all divs
var els = document.getElementsByClassName(id);
for (var i = 0; i < els.length; i++) {
els[i].style.display ="none"
}
// show selected div
els[index].style.display = "block";
}
JSFiddle demo here.
By the way, if the argument is a class name, you should really name it that (not id as you are now, it is very misleading).

Its very simple, this codepen will help you to achieve it.
$(document).ready(function(){
$("img").click(function(){
var classname = this.id;
$('div').removeClass('show');
$("."+classname).addClass('show');
});
});
img{
cursor:pointer;
width : 30px;
padding:20px;
border:1px solid #333;
}
div{
display:none;
}
.show{
display:block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<img src="http://image.flaticon.com/icons/svg/149/149384.svg" id="Phone" />
<img src="http://image.flaticon.com/icons/svg/149/149181.svg" id="chem" />
<img src="http://image.flaticon.com/icons/svg/149/149098.svg" id="cam" />
<div class="Phone">
<h1>Hi This is phone</h1>
</div>
<div class="chem">
<h1>Hi This is chem reaction</h1>
</div>
<div class="cam">
<h1>Hi This is camera</h1>
</div>

I am trying to replace an image with the other one by using javascript but it isn't working.I am new to javascript [duplicate]

I want to change an image to some other image when i click on the object. the code is stacked in the following order:
<li><img><some text></img></li>
<li><img><some text></img></li>
<li><img><some text></img></li>
<li><img><some text></img></li>
<li><img><some text></img></li>
What I wish to do is, when I click on the <li> i want to change the image to a coloured version of the image, i.e. some other image. Now, I know I can use JQuery/JS to accomplish it. But I don't want a huge amount of JS code to accomplish something so simple.
Can it be done using something simpler? Like pseudo selectors? .active class?
I cannot seem to think of it.
To change image onclik with javascript you need to have image with id:
<p>
<img alt="" src="http://www.userinterfaceicons.com/80x80/minimize.png"
style="height: 85px; width: 198px" id="imgClickAndChange" onclick="changeImage()"/>
</p>
Then you could call the javascript function when the image is clicked:
function changeImage() {
if (document.getElementById("imgClickAndChange").src == "http://www.userinterfaceicons.com/80x80/minimize.png"){
document.getElementById("imgClickAndChange").src = "http://www.userinterfaceicons.com/80x80/maximize.png";
} else {
document.getElementById("imgClickAndChange").src = "http://www.userinterfaceicons.com/80x80/minimize.png";
}
}
This code will set the image to maximize.png if the current img.src is set to minimize.png and vice versa.

Or maybe
and that is prob it
<img src="path" onclick="this.src='path'">
How about this? It doesn't require so much coding.
$(".plus").click(function(){
$(this).toggleClass("minus") ;
})
.plus{
background-image: url("https://cdn0.iconfinder.com/data/icons/ie_Bright/128/plus_add_blue.png");
width:130px;
height:130px;
background-repeat:no-repeat;
}
.plus.minus{
background-image: url("https://cdn0.iconfinder.com/data/icons/ie_Bright/128/plus_add_minus.png");
width:130px;
height:130px;
background-repeat:no-repeat;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="plus">CHANGE</div>
If your images are named you can reference them through the DOM and change the source.
document["imgName"].src="../newImgSrc.jpg";
or
document.getElementById("imgName").src="../newImgSrc.jpg";
The most you could do is to trigger a background image change when hovering the LI. If you want something to happen upon clicking an LI and then staying that way, then you'll need to use some JS.
I would name the images starting with bw_ and clr_ and just use JS to swap between them.
example:
$("#images").find('img').bind("click", function() {
var src = $(this).attr("src"),
state = (src.indexOf("bw_") === 0) ? 'bw' : 'clr';
(state === 'bw') ? src = src.replace('bw_','clr_') : src = src.replace('clr_','bw_');
$(this).attr("src", src);
});
link to fiddle: http://jsfiddle.net/felcom/J2ucD/
Here, when clicking next or previous, the src attribute of an img tag is changed to the next or previous value in an array.
<div id="imageGallery">
<img id="image" src="http://adamyost.com/images/wasatch_thumb.gif" />
<div id="previous">Previous</div>
<div id="next">Next</div>
</div>
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
<script>
$( document ).ready(function() {
var images = [
"http://placehold.it/350x150",
"http://placehold.it/150x150",
"http://placehold.it/50x150"
];
var imageIndex = 0;
$("#previous").on("click", function(){
imageIndex = (imageIndex + images.length -1) % (images.length);
$("#image").attr('src', images[imageIndex]);
});
$("#next").on("click", function(){
imageIndex = (imageIndex+1) % (images.length);
$("#image").attr('src', images[imageIndex]);
});
$("#image").attr(images[0]);
});
</script>
I was able to implement this by modifying this answer: jQuery array with next and previous buttons to scroll through entries
If you don't want use js, I think, you can use instead of img and then use css like
a {
background: url('oldImage.png');
}
a:visited {
background: url('newImage.png');
}
EDIT: Nope. Sorry it works only for :hover
You can try something like this:
CSS
div {
width:200px;
height:200px;
background: url(img1.png) center center no-repeat;
}
.visited {
background: url(img2.png) center center no-repeat;
}
HTML
<div href="#" onclick="this.className='visited'">
<p>Content</p>
</div>
Fiddle
This script helps to change the image on click the text:
<script>
$(document).ready(function(){
$('li').click(function(){
var imgpath = $(this).attr('dir');
$('#image').html('<img src='+imgpath+'>');
});
$('.btn').click(function(){
$('#thumbs').fadeIn(500);
$('#image').animate({marginTop:'10px'},200);
$(this).hide();
$('#hide').fadeIn('slow');
});
$('#hide').click(function(){
$('#thumbs').fadeOut(500,function (){
$('#image').animate({marginTop:'50px'},200);
});
$(this).hide();
$('#show').fadeIn('slow');
});
});

How can i make an image set a class to display:none and then set a specific id to display:inline

I'm trying to create a function that hides a class of divs then shows one of those divs by it's id. Here is what I have but I'm not sure if this is the right way to do it. If there is a better way I'm open to it, or if someone can identify an error in this code. What I would like is for the page to load with none of the bio classes visible, then when an image is clicked the bio with the corresponding id appears in its place. Searching only gave me this answer which did not help me. The code below has the bio class divs invisible when the page loads, the image can be clicked but the div does not appear on click. Hopefully this all makes sense.
.bio {
display: none;
}
#id1 {
display: none;
}
#id2 {
display: none;
}
<script language="JavaScript">
function setVisibility(name, id) {
document.getElementByClassName(name).style.display = "none";
document.getElementById(id).style.display = "inline";
}
</script>
<input type="image" src="name1_staff.jpg" onclick="setVisibility('bio', 'id1');" ;>
<input type="image" src="name2_staff.jpg" onclick="setVisibility('bio', 'id2');" ;>
<div class="bio" id="id1">
<h3>text</h3>
<p>more</p>
</div>
<div class="bio" id="id2">
<h3>text</h3>
<p>more</p>
It's wrong way I think. Let's do so:
function removeHidden(className)
{
var classes = className.split(' ');
var newClasses = [];
while (classes.length > 0) {
var name = classes.shift();
if (name != 'hidden' && newClasses.indexOf(name) < 0) {
newClasses.push(name);
}
}
return newClasses.join(' ');
}
function addHidden(className)
{
return removeHidden(className) + ' hidden';
}
function setVisibility(name, id)
{
var x = document.getElementsByClassName(name);
var i;
for (i = 0; i < x.length; i++) {
if (x[i].id == id) {
x[i].className = removeHidden(x[i].className);
} else {
x[i].className = addHidden(x[i].className);
}
}
}
setVisibility('bio', 'id1');
.bio {
/* don't put here display: none */
/* you can delete it if you have no other styles */
}
.hidden {
display: none;
}
<input type="image" src="http://www.hanselman.com/blog/content/binary/WindowsLiveWriter/Hans.NETMVCJeffAtwoodandhistechnicalteam_1349C/stackoverflow-logo-250_3.png" onclick="setVisibility('bio', 'id1');" ;>
<input type="image" src="http://www.hanselman.com/blog/content/binary/WindowsLiveWriter/Hans.NETMVCJeffAtwoodandhistechnicalteam_1349C/stackoverflow-logo-250_3.png" onclick="setVisibility('bio', 'id2');" ;>
<div class="bio" id="id1">
<h3>FIRST DESCRIPTION</h3>
<p>description description description description description</p>
</div>
<div class="bio" id="id2">
<h3>SECOND DESCRIPTION</h3>
<p>description description description description description</p>
</div>
Try this
<script type="text/javascript">
function setVisibility(name, id) {
var x = document.getElementsByClassName(name);
var i;
for (i = 0; i < x.length; i++) {
x[i].style.display = "none";
}
document.getElementById(id).style.display = "inline";
}
</script>
<input type="image" src="name1_staff.jpg" onclick="setVisibility('bio', 'id1');">
<input type="image" src="name2_staff.jpg" onclick="setVisibility('bio', 'id2');">
<div class="bio" id="id1">
<h3>text</h3>
<p>more</p>
</div>
<div class="bio" id="id2">
<h3>text</h3>
<p>more</p>
</div>
Try using the visibility property. In this case, you won't have to deal with your .bio container. You can simply focus on showing and hiding your content. See here.
Keep in mind: With your solution you're setting your containers are always visible. You may also attach a visible property to your container to not get a blank space (if you trigger your 2nd button first).

Change Icon on click and add a css class through javascript

I'm trying to make a expandable h3. For that I'll have a "plus" image to click and when it's clicked has to change to a "minus" image and I need to add a css class to the h3 to show the content. I'll paste all the code below:
<div class="default">
[ManageBlog]
<div class="msearch-result" id="LBSearchResult[moduleid]" style="display: none">
</div>
<div class="head">
<h1 class="blogname">
[BlogName] <img src="/portals/40/Images/Train_Fitness_2015_S/images/plus_symbol.png" alt="Plus Button" id="ExpandBlogDescriptionImg"></h1> [RssFeeds]
<br style="line-height: 12px; clear: both" />
<h3 class="blogdescription">
[BlogDescription]</h3> [Author]
</div>
<br /> [Posts] [Pager]
</div>
<div style="clear: both"></div>
And here is the javascript:
jQuery(document).ready(function() {
$("#ExpandBlogDescriptionImg").click(function() {
var right = "https://train.fitness/portals/40/Images/Train_Fitness_2015_S/images/plus_symbol.png";
var left = "https://train.fitness/portals/40/Images/Train_Fitness_2015_S/images/minus_symbol.png";
element.src = element.bln ? right : left;
element.bln = !element.bln;
});
var img = $("#ExpandBlogDescriptionImg");
if (img.src = "https://train.fitness/portals/40/Images/Train_Fitness_2015_S/images/minus_symbol.png") {
$('.blogdescription').addClass("ExpandBlogDescriptionText");
} else {
$('.blogdescription').removeClass("ExpandBlogDescriptionText");
};
});
you can use .attr function of jquery to set image source like
$('.img-selector').attr('src','plusorminusimagepath.jpg');
and you can have a boolean flag to know if it is less or more
Here i was changing alt attribute of image tag on click. the same way you can change src
jQuery(document).ready(function() {
$("#ExpandBlogDescriptionImg").click(function() {
if ($(this).attr("alt") == "+") {
$(this).attr("alt", "-");
} else {
$(this).attr("alt", "+");
}
});
var img = $("#ExpandBlogDescriptionImg");
if (img.src = "https://train.fitness/portals/40/Images/Train_Fitness_2015_S/images/minus_symbol.png") {
$('.blogdescription').addClass("ExpandBlogDescriptionText");
} else {
$('.blogdescription').removeClass("ExpandBlogDescriptionText");
};
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="default">
[ManageBlog]
<div class="msearch-result" id="LBSearchResult[moduleid]" style="display: none">
</div>
<div class="head">
<h1 class="blogname">
[BlogName] <img alt="+" src="/portals/40/Images/Train_Fitness_2015_S/images/plus_symbol.png" alt="Plus Button" id="ExpandBlogDescriptionImg"></h1> [RssFeeds]
<br style="line-height: 12px; clear: both" />
<h3 class="blogdescription">
[BlogDescription]</h3> [Author]
</div>
<br />[Posts] [Pager]
</div>
<div style="clear: both"></div>
You should use a sprite image and CSS, else when you click and it will load another image, for some time between image would disappear.
HTML
<div class="head">
<h1 class="blogname">
[BlogName] <span class="plus icon"></span></h1>
[RssFeeds]
<br style="line-height: 12px; clear: both" />
<h3 class="blogdescription">
[BlogDescription]</h3>
[Author]</div>
<br />
CSS
.icon{
width:30px;
height:30px;
display:inline-block;
background-image:url(plus-minus-sprite-image.png);
}
.icon.plus{
background-position:20px center;
}
.icon.minus{
background-position:40px center;
}
JS
$('.icon').click(function(){
$(this).toggleClass("plus minus");
if($(this).hasClass("plus")){
$('.blogdescription').addClass("ExpandBlogDescriptionText");
}else{
$('.blogdescription').removeClass("ExpandBlogDescriptionText");
}
// Or $('.blogdescription').toggleClass("ExpandBlogDescriptionText");
});
$("#ExpandBlogDescriptionImg").click( function(e){
var right = "https://train.fitness/portals/40/Images/Train_Fitness_2015_S/images/plus_symbol.png";
var left = "https://train.fitness/portals/40/Images/Train_Fitness_2015_S/images/minus_symbol.png";
if($(e.currentTarget).attr('img') == left){
$(this).hide();
$(e.currentTarget).attr('img',right);
}else{
$(this).show();
$(e.currentTarget).attr('img',left);
}
});

Setting background color of div on click

I have a set of dynamically generated div elements like:
<div on-click="selected">one</div>
<div on-click="selected">two</div>
<div on-click="selected">three</div>
<div on-click="selected">four</div>
<div on-click="selected">five</div>
<div on-click="selected">six</div>
<div on-click="selected">seven</div>
I want to change the background color of div on which it is clicked and lose it when another div is clicked.
I could achieve this using tabindex, but I want to retain it until I click it on the another div or clear it intentionally, which tabindex does not provide.
How can I acieve it using javascript?
<div class="radiodiv" onclick=selected(this)>one</div>
<div class="radiodiv" onclick=selected(this)>two</div>
<div class="radiodiv" onclick=selected(this)>three</div>
<div class="radiodiv" onclick=selected(this)>four</div>
<div class="radiodiv" onclick=selected(this)>five</div>
<div class="radiodiv" onclick=selected(this)>six</div>
<div class="radiodiv" onclick=selected(this)>seven</div>
<script>
var divItems = document.getElementsByClassName("radiodiv");
function selected(item) {
this.clear();
item.style.backgroundColor = 'red';
}
function clear() {
for(var i=0; i < divItems.length; i++) {
var item = divItems[i];
item.style.backgroundColor = 'white';
}
}
</script>
Put all Your 'divs' into one div which will be container.
Then, by js, loop trough them and set css for non-selected and different for selected.
code :
function sel(id) {
var divs=document.getElementById('container').getElementsByTagName('div'); //get all divs from div called container
for(var i=0;i<divs.length; i++) {
if(divs[i]!=id) { //if not selected div set .items css
divs[i].className='items';
}
}
id.className='selitem'; //set different css for selected one
}
/* css for non-selected div*/
.items
{
display:block;
width:200px;
background-color:white;
color:black;
cursor:pointer;
margin-bottom:5px;
}
.items:hover
{
background-color:blue;
color:white;
}
/* css for selected div*/
.selitem
{
display:block;
width:200px;
background-color:red;
color:yellow;
cursor:pointer;
margin-bottom:5px;
}
<div id="container">
<div class="items" onclick="sel(this)">one</div>
<div class="items" onclick="sel(this)">one</div>
<div class="items" onclick="sel(this)">one</div>
<div class="items" onclick="sel(this)">one</div>
<div class="items" onclick="sel(this)">one</div>
<div class="items" onclick="sel(this)">one</div>
<div class="items" onclick="sel(this)">one</div>
</div>
There is explanation in the code.
Try this:
<div onclick="selected(this)">one</div>
<div onclick="selected(this)">two</div>
<div onclick="selected(this)">three</div>
<div onclick="selected(this)">four</div>
<div onclick="selected(this)">five</div>
<div onclick="selected(this)">six</div>
<div onclick="selected(this)">seven</div>
<script>
function selected(element)
{
var divs=document.getElementsByTagName("div");
divs.forEach(function(i)
{
i.style.backgroundColor="auto";
});
element.style.backgroundColor="red";
}
</script>
FYI, without any loops.
var xxx = null;
function sel(element){
if(xxx != null){
xxx.className = "default";
}
element.className = "selected";
xxx = element;
}
The best way to do that, is called a function in JavaScript, onclick or another. In this function you can create your own code, try to change the CSS properties and you will change the background color.
One example that I created:
function onoverbut(elemento)
{
elemento.style.color= "silver";
elemento.style.fontSize= "25px";
}
name function: onoverbut
attribute: elemento, which is the class or id html, that you need to pass.

HTML Javascript Slideshow Optimization

I had to write my own code of a couple of lines for displaying slideshow on my websites splashpage. I couldnt use any plugin as I had designed the website on HTML5 and css3 and images were synchronized to resize with the browser. Now, coming to the actual problem, the last image takes double time as taken by
each image in the list. Below is the HTML and the javascript pasted.
HTML
<div id="backgrounds">
<div class="bgs" style="z-index:1000;">
<!--<p style="z-index:999; margin:0; margin-top:300px; color:red; position:absolute;">Let the Feeling Wrap Around</p>-->
<img src="images/main_nop.jpg" alt="" class="background" />
</div>
<div class="bgs" style="z-index:999; display: none">
<!--<p style="z-index:999; margin:0; margin-top:300px; color:red; position:absolute;">Let the Feeling Wrap Around</p>-->
<img src="images/main_jkl.jpg" alt="" class="background" />
</div>
<div class="bgs" style="z-index:998; display: none">
<!--<p style="z-index:999; margin:0; margin-top:300px; color:red; position:absolute;">Let the Feeling Wrap Around</p>-->
<img src="images/main_ghi.jpg" alt="" class="background" />
</div>
<div class="bgs" style="z-index:997; display: none">
<!--<p style="z-index:999; margin:0; margin-top:300px; color:red; position:absolute;">Let the Feeling Wrap Around</p>-->
<img src="images/main_def.jpg" alt="" class="background" />
</div>
<div class="bgs" style="z-index:996; display: none">
<!--<p style="z-index:999; margin:0; margin-top:300px; color:red; position:absolute;">Let the Feeling Wrap Around</p>-->
<img src="images/main_abc.jpg" alt="" class="background" />
</div>
</div>
JAVASCRIPT
var count = 0;
var repeatCount = 0;
var backgrounds = $('.bgs').length;
function startSlideShow() {
myRecFunc = setInterval(function () {
if (count == backgrounds) {
$('.bgs').eq(0).stop(true, true).hide(1000, 'easeOutExpo');
$('.bgs').eq(backgrounds - 1).show(1000, 'easeOutExpo');
}
if (count < backgrounds) {
$('.bgs').eq(count).stop(true, true).show(1000, 'easeOutExpo');
$('.bgs').eq(count - 1).stop(true, true).hide(1000, 'easeOutExpo');
count++;
}
else {
count = 0;
repeatCount++;
}
}, 1000);
}
startSlideShow();
The first if() in the code above is the one I added to handle the situation I stated on top, thanks in advance for the help.
You have a condition where you do nothing for a whole interval which is your "else" case. Try moving that check inside so that it happens immediately.
