How to add different style with jquery in same div name? - javascript

how to add diferrent style in same div name with jquery?
example like this.
<div id="link">
<div class="one">This is first link</div>
<div class="one">This is second link</div>
<div class="one">This is third link</div>
</div>
and i want to add different color for all text in .one
the first class one with #FFF
the second class one with #000
the third class one with #333

You can do this:
var $oneDivs = $("#link div.one");
$oneDivs.eq(0).css("color","#FFF");
$oneDivs.eq(1).css("color","#000");
$oneDivs.eq(2).css("color","#333");
That is, first select all of the divs by class, then pick out the individual ones by their (zero-based) index and set the required colours.
Demo: http://jsfiddle.net/8kNF6/

var colors = ['#FFF', '#000', '#333']
$('#link div.one').each(function(idx, elem) {
$(elem).css('color', colors[idx]);
});

I realize the question specifically asks how to do it with jQuery, but you do know you could do that with an nth-child css selector and not have to use javascript at all, right?
'just throwin it out there :)
#link div:nth-child(1) { color: #FFF; }
#link div:nth-child(2) { color: #000; }
#link div:nth-child(3) { color: #333; }

how to change the attributes of child divs from the parent div through javascript?

#va{
color:yellow;
}
#v{
color:pink;
}
<div id = "va">
<div id ="v">my name is </div>
<div>khan</div>
</div>
i have tried using document.getelementbyid("va").style.color="yellow"; but the color of element v is not changing i want to change its color by the id of parent i want it to be done through javascript as it is the simple example of the situation in which i am traped plz help
$("#va>#v").css("background-color","green")
#va{
color:yellow;
}
#v{
color:pink;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id = "va"> asdasd
<div id ="v">my name is </div>
<div>khan</div>
</div>
Use > the direct child selector.
The selector will select the direct child(with id v) of element with id va and change color to red
With jquery you have two options, using the .children() method or using .find() method, take a look in this snippet:
$("#va").children().css("color", "red");
//$("#va").find("#v").css("color","blue");
#va {
color: yellow;
}
#v {
color: pink;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="va">
<div id="v">
my name is
</div>
<div>
khan
</div>
</div>
If you want to change the color of ID v, use getElementById("v") rather that getElementById("va")
document.getElementById("v").style.color = "yellow";
#va {
color: yellow;
}
#v {
color: pink;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="va">
<div id="v">my name is </div>
<div>khan</div>
</div>
you can change the class attribute of any element and create the css to what you need using:
document.getElementById("va").setAttribute("class", "yellow-class");
css would bw something like:
.yellow-class{
color: yellow;
}
Colors styles only affect child nodes if the child node's color property is set to initial.
#va{
color:yellow;
}
#v{
color:initial;
}
However, this will remove the default pink color from your tag. There are lots of different ways you could solve this problem but the simplest would be to just create a new style rule and simply use js to add a class to #va to change the style.
#va.yellow #v {
color: yellow;
}
And use this js.
document.getElementById("va").className += " yellow";

Jquery will not select button after class has been toggled

I have some jquery that will, when a button is clicked, switch a class from a button to a different class (i.e. on click switch class from #testButton from .first to .second with an image toggle to show it works). The first click works well and it toggles the image, but the second click does not do anything. It seems as if it is not recognizing the new class. Here is a fiddle.
https://jsfiddle.net/myfb44yu/
This is the problematic javascript.
$(document).ready(function(){
$('.first').click(function(){
alert('works');
$('#testButton').toggleClass('first', 'second');
});
$('.second').click(function(){
alert("works");
$('#testButton').toggleClass('second', 'first');
});
});
The interesting thing is that it works when I use an alert() to check but not when I try to change an img src.
Your main issue here is a syntax error in regards to your .toggleClass, but seeing as others have addressed that, I'd like to point out that you should consider re-thinking how you apply your listeners - just as good habit moving forward.
An overview of jQuery Event Bindings
Think of the elements on your page as items in a store. You're an employee, and your manager says "Go put a red tag on anything in the toys department", and so you do. The next day, he puts 10 new toys in the toy department, and says to you "Why don't all the toys have red tags on them?" He then moves one of the toys to the clothing section and asks you, "Why does this item have a red tag on it?" It's simple. You put the red tags on anything in the toys department when he told you to do it - things got moved around afterwards.
The toys in this example would be your .first and .second elements.
This is how jQuery event bindings work - they only apply to elements that satisfied the selector at the time the event was initialized.
So, if you do $('.myClass').click();, then put .myClass on five buttons - none of those buttons will call this function, as they didn't have listeners put on them.
Similarly, if you put a listener on an element using class, but then remove the class from that element, it will maintain the bound event.
The Solution
$(document).on("click", ".first", function() { } );
This is known as event delegation.
In continuing with my analogy from before, this would be the equivalent of skipping tagging the items altogether, and instead just deciding whether or not they're a toy when the customer brings them to the cash register.
Instead of putting the listener on specific elements, we've put it on the entire page. By using ".first" as the second parameter (which takes a selector), the function will only be executed if the element has class first.
Hope this helps.
EDIT: As I was typing, JHecht left a good answer that points out the same issue I outlined above.
N number of elements can have the same class name ,so that's the reason if your trying to search it as $('.classname') returns an array ,so that's the reason your code is not working.class selector
Id is unique,each element should have a single id . In your code button has two id's and for the same button your trying to toggle first and second,you need not have two separate events for first and second
instead you can write as following
check this snippet
$(document).ready(function() {
var firstElements = $('.first')
var first = firstElements[0];
var secondElements = $('.second');
var second = secondElements[0]
$("#testButton").click(function() {
alert('works');
$(this).toggleClass('first').toggleClass('second');
});
});
.first {
color: red;
}
.second {
color: green;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<img src="img/images.jpeg" alt="" id="testImage">
<div id="testDiv">
<button type="button" id='testButton' class='first'>Hi</button>
</div>
Hope it helps
Ho about this solution. Hope it helps!
$(document).ready(function(){
$("#testButton").click(function(){
if($(this).prop("class") === "first"){
alert('first');
$(this).removeClass("first").addClass("second");
}
else if($(this).prop("class") === "second"){
alert("second");
$(this).removeClass("second").addClass("first");
}
});
});
.first{
color: red;
}
.second{
color: blue;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<img src="img/images.jpeg" alt="" id="testImage">
<div id="testDiv">
<button type="button" id='testButton' class='first'>Hi</button>
</div>
I hope that what I am about to say makes more sense than I feel it does.
Your issue is that when you assign the click events, there is not currently an element that has a class of .second.
Also, your code is wrong. toggleClass accepts a few arguments, the first is a string of classes, the second is an optional parameter to check whether or not to toggle the classes on or off.
A way to accomplish what you want without changing a whole lot of code is event delegation, shown below.
$(function() {
$(document).on('click', '.btn-first,.btn-second', function() {
//here we are adding the click event on the document object, and telling it that we only want to delegate this event to an object that matches the classes of .btn-first or .btn-second.
//Note: to those saying "why not just do it on the .btn class an avoid having to do this", it is so he can see what delegation looks like. But you are correct, with this markup it would be better to simply add the click event on the .btn class.
$(this).toggleClass('btn-first btn-second');
});
});
.btn {
padding: 4px 8px;
border-radius: 3px;
border: 1px solid grey;
}
.btn-first {
background-color: green;
border-color: green;
}
.btn-second {
background-color: orange;
border-color: orange
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<img src="img/images.jpeg" alt="" id="testImage">
<div id="testDiv">
<button type="button" id='testButton' class='btn btn-first'>Hi</button>
</div>
A combination of javascript, CSS and HTML to toggle the class of #testButton when any element of class "first" or "second" is clicked, including the test button itself. The posted code was changed to supply JQuery's .toggleClass method with a space separated list of class names. Click "run snippet" to test the effect.
$(document).ready(function(){
$('.first').click(function(){
$('#testButton').toggleClass('first second');
});
$('.second').click(function(){
$('#testButton').toggleClass('first second');
});
});
.first { border: thick outset green;}
.second { border: thick inset red;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p class="first">This paragraph has first class</p>
<p class="second">This paragraph has second class</p>
<button type="button" id="testButton" class="first">this button starts out first class</div>
The script can then be simplified by combining multiple class names in a single selector, leaving just:
$(document).ready(function(){
$('.first, .second').click(function(){
$('#testButton').toggleClass('first second');
});
});
Make a neutral class that the buttons both share (.btn).
Then add one of the state classes to each button (.first or .second).
Delegate the click event to the neutral class only ($('.btn').on('click',...).
Then toggle both state classes on this ($(this).toggleClass('first second');)
The images change by CSS, each button has 2 images which alternate between display:none/block according to the button's state class.
There is an example with the images outside of buttons and another example that doesn't toggle classes around.
SNIPPET
$('.btn').on('click', function() {
$(this).toggleClass('first second');
});
/* OR */
$('.alt').on('click', function() {
$('.img').toggle();
});
.first > .one {
display: block;
}
.first > .two {
display: none;
}
.second > .one {
display: none;
}
.second > .two {
display: block;
}
.first + .one {
display: block;
}
.first + .one + .two {
display: none;
}
.second + .one {
display: none;
}
.second + .one + .two {
display: block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p>Use jQuery with CSS</p>
<button class='btn first'>
<img src='http://placehold.it/50x50/000/fff?text=1' class='one'>
<img src='http://placehold.it/50x50/fff/000?text=2' class='two'>
</button>
<button class='btn second'>
<img src='http://placehold.it/50x50/0e0/960?text=1' class='one'>
<img src='http://placehold.it/50x50/fff/000?text=2' class='two'>

css style loading + id. eg loading1, loading300

I have this in css:
#loading{
display:none;
}
the problem is, i need to display none this loading div, that come with an id after loading name.
eg:
<div id=loading1></div>
<div id=loading422></div>
<div id=loading9232></div>
I want to apply loading style in all this divs, can i do that? how would it be?
thank you!
I want to apply loading style in all this divs, can i do that?
Yes, with an attribute starts with selector:
[id^=loading] {
display: none;
}
That matches any element whose id attribute starts with loading.
Example:
[id^=loading] {
color: blue;
}
<div id="loading1">loading1</div>
<div id="loading12">loading12</div>
<div id="loading123">loading123</div>
<div id="notloading">notloading, so not affected</div>
<div id="loading">loading with nothing after</div>
hello freind you can put an class attribut and name it loading
like this
<div id=loading1 class="loading"></div>
<div id=loading422 class="loading"></div>
<div id=loading9232 class="loading"></div>
and call it in your css like this
.loading{
display:none;
}
that's can be better than id class is good
i hope to find that is helpfull
Try this:
div[id^=loading]{display:none;}

HTML objects growing and pushing others

How could I make it so that given two elements let's say these boxes:
If I clicked over one, it would grow, and the other would shrink like and vice versa:
How can I do this?
I have seen this sort of done with CSS, using the focus tag and adjusting the width. But I have two problems there, first how could I affect the other element, and second as far as I can tell adjusting width will only stretch them right. I have seen people change the way they float the elements to deal with that, but I don't want to move them around the page to do this.
Here are 2 examples without Javascript/jQuery:
Pure CSS - Trigger on click: (example)
Using the checkbox hack in CSS you can effectively toggle the widths of the elements when the checkbox is :checked. Here is what part of the CSS looks like:
input[type=checkbox]:checked ~ .red {
width:70%;
}
input[type=checkbox]:checked ~ .green {
width:20%;
}
Go to the example for the full CSS.
HTML
<input type="checkbox" id="toggle" />
<div class="red">
<label for="toggle"></label>
</div>
<div class="green">
<label for="toggle"></label>
</div>
You might also be interested in the original example I made. It takes a different approach, though it doesn't fully work.
Pure CSS - Trigger on hover: (example)
Unfortunately, neither the adjacent selector, nor the general sibling selector can select previous elements, therefore it makes this a little difficult. I placed 2 general elements before the main elements in order to somewhat solve this issue.
.greenS:hover, .greenS:hover ~ .green,
.redS:hover, .redS:hover ~ .red {
width:72%;
}
.greenS:hover ~ .redS, .greenS:hover ~ .red,
.redS:hover ~ .greenS, .redS:hover ~ .green {
width:22%;
}
HTML
<div class="redS"></div><div class="greenS"></div>
<div class="red"></div>
<div class="green"></div>
Since this was tagged as JS/jQuery, here are 2 alternative solutions.
JS/jQuery - Trigger on click: (example)
$('.red, .green').click(function(){
$('.red').toggleClass('expanded')
.next('.green').toggleClass('contracted');
});
JS/jQuery - Trigger on hover: (example)
$('.red').hover(function(){
$(this).toggleClass('expanded')
.next('.green').toggleClass('contracted');
});
$('.green').hover(function(){
$(this).toggleClass('expanded')
.prev('.red').toggleClass('contracted');
});
See jQuery .animate() method documentation.
Example on jsfiddle:
.box {
width: 100px;
height: 100px;
display: inline-block;
}
#box1 {
background: red;
}
#box2 {
background: blue;
}
<div class="box" id="box1"></div>
<div class="box" id="box2"></div>
$('.box').click(function() {
var currentWidth = $(this).outerWidth(),
siblingCurrentWidth = $(this).siblings('.box').outerWidth();
$(this).animate({'width' : currentWidth/2})
.siblings('.box').animate({'width' : siblingCurrentWidth*2});
});
This is a very simple example with several flaws, but it demonstrates a possibility for what your purpose is.
Simple example http://jsfiddle.net/PeLub/ ( modify how you need) .
<div class="box" id="first"></div>
<div class="box" id="second"></div>
$("#first").click(function(){
$(this).animate({width:'50px'}, 500);
$("#second").animate({width:'150px'}, 500);
});
$("#second").click(function(){
$(this).animate({width:'50px'}, 500);
$("#first").animate({width:'150px'}, 500);
});

How to change the color of another link on hover?

This is the simple HTML code:
<li class="main">
ImageLink <!--1st anchor tag-->
ImageName <!--2nd anchor tag-->
</li>
Is it possible to change the color of 2nd anchor tag on hover state of 1st anchor tag? (And vice versa.)
Not with css. This kind of actions can only be done by script.
If you use jQuery you could add the following script:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.min.js"></script>
<script type="text/javascript>
$(document).ready(function(){
var a1 = $('a:first');
var a2 = $('a:second');
a1.hover(function(){ a2.toggleClass('hover') }, function(){ a2.toggleClass('hover') });
a2.hover(function(){ a1.toggleClass('hover') }, function(){ a1.toggleClass('hover') });
});
</script>
Now you can use the hover class to specify the color:
.hover { color: red; }
Edit
It would be easier to give both a's an id, so you could reference them by using var a1 = $('#a1');.
With CSS, it's possible to change the color of the 2nd anchor tag on hover of the 1st anchor tag with a sibling selector, but I don't think you can do it vice-versa:
a:hover + a {
color: red;
}
JSFiddle preview: http://jsfiddle.net/9Ezt5/
See http://www.w3.org/TR/CSS2/selector.html#adjacent-selectors
However, note that adjacent sibling selectors are not supported on all browsers: http://www.quirksmode.org/css/contents.html
Yes you can do it with pure css.
for example:
a:hover + a{
background:red;
}
Check this for more
http://jsfiddle.net/Bw5by/
In Jquery you can do it like this,
$("#first").hover(function(){
$('#second').css('color','red')
},function(){
$('#second').css('color','blue')
});
See it in action here,
http://jsfiddle.net/gagan/NYAHY/1/
If those are the only two links in the list item tag, then you could do something like this:
li.main:hover a
{
color: red;
}
li.main a:hover
{
color: blue;
}
Then your hovered link will be blue, and all the other ones (in this case just that other one) will be red.
