JQuery: How to find out how many children an element has?
(2 answers)
Closed 8 years ago.
Fiddle: http://liveweave.com/Aq56fN
In my fiddle I have a div that has a few elements as it's children. Is there anyway to detect how many children an element has as a numeric value? If so how would something like this be done?
JavaScript/JQuery:
$(".grab-contenu").on('click', function() {
$(".spectacle-contenu").html(
$(".contenu").children().toString()
);
});
HTML:
<div class="contenu" align="center">
<header class="largeur-objet">My width is 80%</header>
<button class="grab-contenu">Detect children number</button>
<footer class="spectacle-contenu">Show children number</footer>
</div>
Any help is greatly appreciated.
Try changing
$(".contenu").children().toString()
To
$(".contenu").children().length

How do I change the text of a span element using JavaScript?
(18 answers)
Closed 5 years ago.
I want to know what javascript code I can use to edit the text of this word?
This is not a duplicate because this has multiple divs in a div. And the target word is located in a div that is inside the more divs.
<div id="jump">
<div class="kick">
<div class="meet">
<div class="balls">
<div class="word">
Hello
</div>
</div>
</div>
It's the 1st element that has this class...
document.getElementsByClassName('word')[0].innerHTML='Goodbye';
It's the 5th element that has this tag...
document.getElementsByTagName('div')[4].innerHTML='Goodbye';
You can use next code:
document.querySelector('.word').textContent = 'Hello World!';
<div id="jump">
<div class="kick">
<div class="meet">
<div class="balls">
<div class="word">
Hello
</div>
</div>
</div>
But if you has few elements with class word, function 'querySelectror fining only first element'.If you need get many elements, you can use document.querySelectorAll --- is HTMLCollection (not array).
I don't recommend to use getElementByClassName - is very slowly method.
Method getElementsByTagName -faster that querySelectorAll , but it use only tagName. getElementById -is the fastest menthod finding of elements.
But that method find only first element with current ID.

Event binding on dynamically created elements?

Here I have an example:
$('#key').on('click', function(){
$('.task').html("<button id='key'>Button</button>"+Date());
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class='task'>
<button id='key'>Button</button>
</div>
How I can apply javascript for overwriting element and get different time for each button press?
Clearly there is no need to ovveride button here. Do not ovveride button. Use a span for date.
$('#key').on('click', function(){
$('.datestr').html(Date());
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class='task'>
<button id='key'>Button</button>
<span class='datestr'></span>
</div>

Replace Div with another Div
(3 answers)
Closed 6 years ago.
I need a simple solution for replacing a div with a new div, cross-browser compatible using javascript or JQuery. I'll add some code below. Div "myDiv-B" needs to be replaced by a new div:
<div id="myDiv-C">{% include 'snippets/contactpaneel.rain' %}</div>
Here are my divs
<div id="myDiv-A">
<div id="myDiv-B"></div>
</div>
You should use .replaceWith() method.
.replaceWith method replace each element in the set of matched
elements.
$('#myDiv-B').replaceWith('<div>Hello</div>');
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="myDiv-A">
<div id="myDiv-B"></div>
</div>

jQuery OR Selector?
(6 answers)
Closed 6 years ago.
Here is my current code:
$(".close_btn").click(function(e) {
$(".box1").fadeOut(100);
$(".box2").fadeOut(100);
});
As you see, currently, when you click on .close_btn, both .box1 and .box2 will be hidden. Now I want to use $(this) and .closest() to hide just one box (the parent of clicked .close_btn, there are two .close_btn). I mean I want something like this:
$(".close_btn").click(function(e) {
$(this).closest(".box1" OR ".box2").fadeOut(100);
});
Is doing that possible?
You can just use a comma to separate multiple selectors:
$(".close_btn").click(function(e) {
$(this).closest(".box2, .box1").fadeOut(100);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="box1">
<button class="close_btn">Close</button>
</div>
<div class="box2">
<button class="close_btn">Close</button>
</div>
