The example below works. (Example taken from w3cschools, and hacked a bit.)
Clicking anywhere in the DIV will cause the address class div to disappear.
However, changing the third line of the script to read
$("button").click(function(){
instead of "div" and it just sits there like a paperweight. What am I missing.
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">
</script>
<script>
$(document).ready(function(){
$("div").click(function(){
$(this).children(".address").toggle("slow");
});
});
</script>
<style type="text/css">
div.ex
{
background-color:#e5eecc;
padding:7px;
border:solid 1px #c3c3c3;
}
</style>
</head>
<body>
<h3>Island Trading</h3>
<div class=ex>
<button>Hide me</button>
<div class=address>
<p>Contact: Helen Bennett<br>
Garden House Crowther Way<br>
London</p>
</div>
</div>
<h3>Paris spécialités</h3>
<div class=ex>
<button class="hide">Hide me</button>
<div class=address>
<p>Contact: Marie Bertrand<br>
265, Boulevard Charonne<br>

</div>
</div>
</body>
</html>
Change
$(this).children(".address").toggle("slow");
To something like:
$('.address').toggle("slow");
OR
$(this).siblings(".address").toggle("slow");
Once you make the listener act on the button element, .address is not a child of button any longer. It's a sibling. If there will be multiple .address classes on your page, you must use siblings.
http://jsfiddle.net/9S722/1/
Try this:
$("button").on("click", function(){
$(this).parent().children(".address").toggle("slow");
});
http://jsfiddle.net/hescano/9S722/
$(this).parent().children(".address").toggle("slow");
The button doesn't have children
$("div").click(function(){
$(this).children(".address").toggle("slow");
});
The meaning of such code above is that, when click trigger in div container, it will go through its children for matching "address" class attribute.
However, if you just change $("div") to $("button"), but no child appears within button element. nothing matches for toggle function, just ignore it.
You should change code to as below:
$("button").click(function () {
$(this).next(".address").toggle("slow");
});
which find next sibling to button element. That is the element you want.

I want to append an element of H2 <h2>H2</h2> to the html as shown below
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
</head>
<body>
<div id="a">
<h1>H1</h1>
<!--I want to add H2 here-->
<h3>H3</h3>
</div>
<div id="b">
</div>
</body>
</html>
I query the div like this var mydiv = $("#a")[0]; and then I want to append <h2>H2</h2> inside myDiv, but after <h1>H1</h1> OR before <h3>H3</h3>. I have played around a bit with after(), insertAfter(), before(), insertBefore() with no luck, because i want to target and use the object 'myDiv' and not the whole html page.
EDIT: Some things I have tried
I have tried the following:
var myDiv = $("#a")[0]
$(myDiv).append("<h2>H2</h2>")
This adds the element to the end of the div
Also tried this:
$("h1").after("<h2>H2</h2>")
This adds <h2>H2</h2> after every <h1>H1</h1> which is not what I need to do, I need to add <h2>H2</h2> only inside the selected div which in this case is myDiv
Use jQuery#after and jQuery#find
var myDiv = $("#a")[0];
$(myDiv).find('h1').after("<h2>H2</h2>");
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="a">
<h1>H1</h1>
<!--I want to add H2 here-->
<h3>H3</h3>
</div>
<div id="b"></div>
or
$("#a").find("h1").after("<h2>H2</h2>");
or
$("#a h1").after("<h2>H2</h2>");
Your code is correct, only need change the selector adding h1 in the myDiv selector.
Example:
var myDiv = $("#a h1")[0]
$(myDiv).after("<h2>H2</h2>")
I have a this html page, Whenever the element with class name FreeSeat is clicked I want to change the colour of that div element.Below is my html page
<html>
<head>

</title>
<link type="text/css" rel="stylesheet" href="Seat.css">

<body>
<div id="Bus">
<div class="Row">
<div class="FreeSeat" ></div>
<div class="FreeSeat" ></div>
<div class="ResSeat" ></div>
<div class="ResSeat" ></div>
<div class="ResSeat" ></div>
</div>
</div>
<body>
</html>
It will be very helpful if anyone can help me out with this .
Considering that you want to use pure JS and not any library, you'd have to manually add event listeners to your classes.
And it has been solved for a similar problem here
var freeclass = document.getElementsByClassName("FreeSeat");
var myFunction_Free = function() {
this.style.color = "blue";
}
for(var i=0;i<freeclass.length;i++){
freeclass[i].addEventListener('click', myFunction_Free, false);
}
But for your case, here's a working fiddle
JQuery is amazing for these sorts of things.
Say you have a div with id 'box1'
<div id='box1'></div>
Style it with css
#box1 {
width:100px;
height:100px;
background-color:white;
border:1px solid black;
}
Using JQuery, you can make this call:
$( "#box1" ).click(function() {
$('#box1').css('background-color', 'red');
});
And now whenever your div is clicked, the colour will change, you can customise this however much you like.
Here is a JSFiddle demo.
Also, since you didn't specify exactly what you want to change the colour of, in my example jquery, it is telling the browser that when a div with an id of box1is clicked, change the background-color of the div with an id of box1, you can change anything though.
If you have a <p> tag you can change that too when the div is clicked, hope this helped!
You can use the following method to change the background color of an element by class:
const free_seat = document.getElementsByClassName('FreeSeat');
free_seat[0].style.backgroundColor = '#ff0';
Each element can be referenced by its index:
free_seat[0] // first div
free_seat[1] // second div
Therefore, we can create a function that will be called whenever the click event is delivered to the target:
const change_color = () => {
this.style.backgroundColor = '#ff0';
};
for (let i = 0; i < free_seat.length; i++) {
free_seat[i].addEventListener('click', change_color);
}
Note: You can also use document.querySelectorAll('.FreeSeat') to obtain a NodeList of elements of a certain class.
You can use simply the css focus pseudo-class for this:
#foo:focus {
background-color:red;
}
<div id="foo" tabindex="1">hello world!</div>
Dont forget to set the tabindex.
I am using the following HTML code:
<!DOCTYPE html>
<html>
<head>
<title>Project Quiz</title>
<link rel="stylesheet" type="text/css" href="z/baseCss.CSS">
<script src="/jquery-1.9.1.min.js"></script>
<script src="/baseJS.js"></script>
</head>
<body>
<div id=header></div>
<div id=contain>
<h1>Welcome to my web application</br>
Please enter your name, click 'continue' and have fun</h1>
<form>
<input type="text" id="name" value="John Doe"/>
</form>
<div class="awesome">Continue</div><br/>
</div>
<div id=footer></div>
</body>
</html>
and a code of jQuery:
$(document).ready(function(){
$("input")
.focus(function(){
$(this).css('outline-color','#559FFF');
$(this).blur(function(){
$(this).css("outline-color","#FF0000");
});
});
$("input").click(function(){
var value = $(this).val(function(){
$(this).html("");
});
});
$(".awesome").click(function(){
b._slide(1000);
});
var b = $("div:nth-child(2)");
alert(b);
});
My problem is that I can't figure it out how to select all children of <div id="contain"> and just make them fade out when I click my div button which is the one with the "awesome" class.
This is what I have tried so far:
$(".contain").each(function(){
$(this).fadeOut(1000);
});
but it didnt work also i tried:
$(".contain").children(function(){
$(this).fadeOut(1000);
});
Same result here.
What am I doing wrong? I only need to fadeOut the content of <div id="contain"> and keep everything else the same as it is.
You need to use:
$("#contain").children().fadeOut(1000);
$(this) is your selector
.children() selects all the children of an element
.fadeOut(1000) fades out the current selection
Your attempts were wrong because:
$(".contain").each(function(){ $(this).fadeOut(1000); });
Selects all the elements with class .contain and hides them
$(".contain").children(function(){ $(this).fadeOut(1000); });
Selects the elements with class .contain, and then you're passing a function to .children() which it does not handle.
Note, in your case contain is an ID and not a class.
beside shangeing the "." to "#" form the jquery selector, if you don't need to insert anything else or display new content into <div id="contain">, you can just do this
$("#contain").fade(1000);
all the child will fade too
I want to blur my images by clicking on it. I am using javascript on click event for this purpose. But it is not working exactly as I want. My code is given below:
<script>
$(document).ready(function(){
$(".ww").click(function(){
$(this).css("opacity","0.2");
});
});
</script>
<div class="bg">
<div class="img ww1"><center><img src="img.jpg" /></center></div>
<div class="canname"><center>GHULAM MUSTAFA</center></div>
<div class="partyname"><center>JATOI <span style="color:#CCC;">NPP</span></center></div>
</div>
<div class="bg">
<div class="img ww2"><center><img src="img.jpg" /></center></div>
<div class="canname"><center>GHULAM MUSTAFA</center></div>
<div class="partyname"><center>JATOI <span style="color:#CCC;">NPP</span></center></div>
</div>
I want that when I click first image then its opacity would set. And that when I click second image so the opacity of first image would finish and second image would set.
As the others already tried to explain, you have to use a selector which actually selects both elements, since you want to bind the event handler to both of them. $('.ww') does not select any element in the code you posted.
Toggling the opacity can be easier done when using a class:
.selected {
opacity: 0.2;
}
Add the class to the clicked element and removed it from the element currently having the class:
$(".img").click(function(){
$('.img.selected').add(this).toggleClass('selected');
});
Have a look at this DEMO. This should give you enough information to apply it to your situation.
Because a selector .ww does not match ww1 and ww2.
You can see that with
console.log($(".ww").length);
Use the common class img or add the class ww.

I have this HTML:
<body>
<div id="switcher" class="switcher">
<h3>Style Switcher</h3>
<button id="switcher-default">
Default
</button>
<button id="switcher-narrow">
Narrow Column

<p>asdfasdfasdfas dsadf</p>
<p>asd'lfkasdf</p>
<script src="jquery.js"></script>
<script src="test.js"></script>
</body>
I want to add a class to all body elements except my first div (which has the id called switcher), when I click on the Large print button.
I have tried
$(document).ready(function(){
$("#switcher-large").bind("click", function(){
$("body:not(:first-child)").addClass("large");
});
});
and
$(document).ready(function(){
$("#switcher-large").bind("click", function(){
$("body:not(div)").addClass("large");
});
});
and
$(document).ready(function(){
$("#switcher-large").bind("click", function(){
$("body").not("#switcher").addClass("large");
});
});
but none seem to work (the class applies to all elements).
I don't want to find an alternate way like selecting only p elements. I just want to understand why the selectors I used don't work...
You need to exclude the document.body itself. Like
$("body *").not("#switcher").addClass("large");
This will query for all children of body, excluding #switcher. Maybe more convinient:
$(document.body).contents().not('#switcher').addClass('large');
$("body").children().not("#switcher").addClass("large");
