I have a bunch of html elements with same class and a JQuery click function when i click on one of these elements, all of the same class are affected by this function.
My question: how can I modify the following code in order to affect only clicked element and not all of the same class.
jquery
$('.editorTile').click(function(event){
$(this).data('type', selectedTile);
$(this).data('imgx', selectedTile_imgX);
$(this).data('imgy', selectedTile_imgY);
});
html
<div class="level">
<div class="a editorTile" ...>
<div class="a editorTile" ...> // affect only this
<div class="a editorTile" ...>
<div class="a editorTile" ...> // or this...
</div>
It already would work the way you have it but it won't be obvious. In this Demo click each line.
this points to the owner of the function which is in this case the specific element that happens to be clicked. A more technical term for an element that gets clicked hovered upon, etc. is said to be the "origin of the event". You can also use the event.target property which (like this but much less confusing) points to the "origin of events". The second example in the Demo shows the use of event.target.
Demo
$('.a').click(function(event){
$(this).css('background', 'red');
});
$('.b').on('click', function(e) {
$(e.target).css('font-size','36px');
});
<div class="levelA">
<div class="a">this</div>
<div class="a">is a</div>
<div class="a">keyword</div>
<div class="a">it works!</div>
</div>
<div class="levelB">
<div class="b">event.target</div>
<div class="b">is a</div>
<div class="b">property</div>
<div class="b">of the Event Object</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Here is simple and easy solution:
<div class="level">
<div class="a editorTile">h</div>
<div class="a editorTile">g</div>
<div class="a editorTile">g</div>
<div class="a editorTile">g</div>
</div>
$('.editorTile').each(function(){
$(this).click(function(){
$(this).text("I am clicked");
});
});
or you want something else so you can ask.
You will have to generate dynamic class or id to get that particular div as selector.
The other way of solving this would be to use :eq(n) along with selector if you know which div you have to invoke the click.
For example in your case :-
<div class="level">
<div class="a editorTile" ...>
<div class="a editorTile" ...> // affect only this
<div class="a editorTile" ...>
<div class="a editorTile" ...> // or this...
$("div.editorTile:eq(2)") && $("div.editorTile(4)") gives you second and fourth element.
For that you have to already know the exact div order

I'm learning Javascript and jQuery and I'm stuck at this one problem. Let's say my code looks like this:
<div id="hey"> hey </div>
<div id="how"> how </div>
<div id="are"> are </div>
<div id="you"> you </div>
Now, if i click one of the div's, i want the other ones to disappear.
I know, I could create 4 functions for each one of them with on.click hey and display none with how , are and you. But is there a easier way? I bet there is, with classes maybe?
Thanks for responding!
Use siblings to get reference to its "brothers".
Given a jQuery object that represents a set of DOM elements, the .siblings() method allows us to search through the siblings of these elements in the DOM tree and construct a new jQuery object from the matching elements.
$('div').click(function(){
$(this).siblings().hide();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="hey"> hey </div>
<div id="how"> how </div>
<div id="are"> are </div>
<div id="you"> you </div>
Or you can hide all the other div which not the clicked element using not
Remove elements from the set of matched elements.
$('div').click(function() {
$('div').not(this).hide();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="hey"> hey </div>
<div id="how"> how </div>
<div id="are"> are </div>
<div id="you"> you </div>
You can just hide siblings() of clicked div.
$('div').click(function() {
$(this).siblings().fadeOut()
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="hey">hey</div>
<div id="how">how</div>
<div id="are">are</div>
<div id="you">you</div>
Yeah there are some easier ways and I could tell a one from it,
Set a common class to all the elements that you are gonna target,
<div class="clickable" id="hey"> hey </div>
<div class="clickable" id="how"> how </div>
<div class="clickable" id="are"> are </div>
<div class="clickable" id="you"> you </div>
And you have to bind a single click event by using a class selector,
$(".clickable").on("click", function(){ });
Now use the .siblings() functions to hide the required elements,
$(".clickable").on("click", function(){
$(this).siblings(".clickable").hide();
});
But using a toggle instead of hide would sounds logical,
$(".clickable").on("click", function(){
$(this).siblings(".clickable").toggle();
});
Since you can do the same operation over all the elements.
You can use not to avoid element and this will indicate current instance.
$(document).ready(function(){
$("div").on("click",function(){
$("div").not(this).hide("slow");
})
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="hey"> hey </div>
<div id="how"> how </div>
<div id="are"> are </div>
<div id="you"> you </div>
Assign a class to each of the elements:
<div id="hey" class='sth'> hey </div>
<div id="how" class='sth'> how </div>
<div id="are" class='sth'> are </div>
<div id="you"class='sth' > you </div>
And write a js function onclick.
Remove class 'sth' from 'this' element in this function
Hide all elements with class 'sth' $('.sth').hide();
For this example - you don't need to add any further selectors to target the div's although in reality - this solution wwould cause all divs on the page to be affectecd - adding classes would be my actual suggestion: - but this works for this example. Click a div and all divs are hidden then the clicked one is shown. I also added a reset button to allow all divs to reappear.
$('div').click(function(){
$('div').hide();
$(this).show();
});
$('#reset').click(function(){
$('div').show();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="hey"> hey </div>
<div id="how"> how </div>
<div id="are"> are </div>
<div id="you"> you </div>
<hr/>
<button type="button" id="reset">Reset</button>
$(document).ready(function(){
$("div").on("click",function(){
$("div").not(this).toggle("slow");
})
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="hey"> hey </div>
<div id="how"> how </div>
<div id="are"> are </div>
<div id="you"> you </div>
I am looking for jQuery slector that will find all descendants of passed jQuery object that are not nested in any element that fits same selector. Consider following HTML:
<body>
<div class="container" id="1">
<div class="container" id="11"></div>
<div class="container" id="12"></div>
</div>
<div class="container" id="2"></div>
<div class="noncontainer">
<div class="container" id="3">
<div class="container" id="31"></div>
</div>
</div>
</body>
In this example $("body").find(".container magicSelector") should return divs 1, 2 and 3. $("#1").find(".container magicSelector") should return divs 11 and 12.
EDIT: I have wrote a function for that here, but I think that selector would be cleaner and faster.
Use not() for first case
$("body").find(".container").not('.container .container');
And for second use descendent in the selector
$("body").find('.container .container');
I have a list which contains of several items that are hidden.
In my JS i want a function that changes the items of this list so it becomes visible. I want each item to become visible if a certain event has happened. The event is working fine and can be considered as shakeCount= 6, to test it properly.
Here is my list:
<div class="container">
<div class="list-group">
<div id="s1">Shake1</div>
<div id="s2">Shake2</div>
<div id="s3">Shake3</div>
</div>
</div>
What i tried so far and didn't work:
function nR(){
if (shakeCount>5)
document.getElementbyId("s1").style.visibility ="visible";
}
Thanks in advance!
Have you tried using Toggle? I would recommend it but you may need to remove the "hidden" class from your elements and add in the style="display: none;" attribute to each in order to default them to hidden.
<div class="container">
<div class="list-group">
<div id="s1">Shake1</div>
<div id="s2">Shake2</div>
<div id="s3">Shake3</div>
</div>
</div>
function nR(){
if (shakeCount>5)
document.getElementbyId("s1").toggle();
}
First, you're using getElementbyId -- it should be getElementById (missing capital 'B').
Second, you've made the #shake links visibility:hidden, but you are targeting the wrapping div when you run your js.
var shakeCount = 6;
if (shakeCount>5)
document.getElementById("s1").style.visibility ="visible";
.hidden {visibility: hidden;}
<div class="container">
<div class="list-group">
<div id="s1" class="list-group-item hidden"><a href="#shake1" >Shake1</a></div>
<div id="s2" class="list-group-item hidden"><a href="#shake2" >Shake2</a></div>
<div id="s3" class="list-group-item hidden"><a href="#shake3" >Shake3</a></div>
</div>
</div>
The above code hides the wrapping div elements instead of the links so that they are shown when the js runs.
What is the proper way to re-apply jquery to objects which are cloned??
I have an example I rigged up in jsfiddle here: http://jsfiddle.net/49o6arLu/16/
<div class="hidden element-holder">
<div class="element">
<div class="button">Button</div>
<div class="green-square"></div>
</div>
</div>
<div class="element">
<div class="button">Button</div>
<div class="green-square"></div>
</div>
<div class="clear"></div>
<div class="add-element">Add Element</div>
$('div.button').click(function(event) {
if($(this).parent().children('.green-square').is(':visible')) {
$(this).parent().children('.green-square').hide();
}else{
$(this).parent().children('.green-square').show();
}
});
$('div.add-element').click(function(event) {
$('div.element-holder').children('div').clone().insertAfter($('div.element-holder'));
});
As you can see, the initial displayed box and button work just fine. However, When you add another element the new element button does not work anymore.
I understand why I have this problem, however I don't know the proper way I should go about re-applying the Jquery to the new elements which are cloned.
Can someone provide a solution to the jquery and provide some explanation as to what you did?
Thanks!
You can save the need to re-apply the handler to all the appended elements by having a single delegated click handler on a common parent element.
First of all amend your HTML to include the container, in this case #element-container:
<div class="hidden element-holder">
<div class="element">
<div class="button">Button</div>
<div class="green-square"></div>
</div>
</div>
<div id="element-container">
<div class="element">
<div class="button">Button</div>
<div class="green-square"></div>
</div>
<div class="clear"></div>
</div>
<div class="add-element">Add Element</div>
Then you can amend the Add Element button to append to that container:
$('div.add-element').click(function (event) {
$('div.element-holder').children('div').clone().appendTo('#element-container');
});
Finally you can add the delegated event handler to the new #element-container. Note that I also shortened the logic using toggle() and siblings():
$('#element-container').on('click', 'div.button', function (event) {
$(this).siblings('.green-square').toggle()
});
Example fiddle
In order to copy event handlers you should send true in the clone method:
$('div.add-element').click(function(event) {
$('div.element-holder').children('div').clone(true).insertAfter($('div.element-holder'));});
What is the best way to do this dynamic events linking between divs in jquery.
my HTML page:
<html>
<body>
<div id="parent1"></div>
<div id="parent2"></div>
<div id="parent3"></div>
<div id="child1"></div>
<div id="child2"></div>
<div id="child3"></div>
</body>
</html>
for each clicked parent i want to .toggle its child
Example :: if parent2 clicked, .toggle will be applied on child2 only
my parents and childs divs are dynamically created so their number is not static, i think .live should be used here, but i have no idea how to achieve that.
Thanks
This should do it, using the rel attribute to note link. You could also do the same thing by parsing the ID and so on, but I find this solution more semantic (if it means something) :
<html>
<body>
<div id="parent1" class="parents" rel="child1"></div>
<div id="parent2" class="parents" rel="child2"></div>
<div id="parent3" class="parents" rel="child3"></div>
<div id="child1"></div>
<div id="child2"></div>
<div id="child3"></div>
</body>
</html>
jQuery(function(){
jQuery(".parents").live("click", function(){
jQuery("#"+jQuery(this).attr("rel")).toggle();
});
});
This will work with your current structure (another option is to extract the number, same general idea):
$("[id^=parent]").live('click', function(){
var childId = this.id.replace('parent', 'child');
$('#' + childId).toggle();
});
Using the startsWith selector and slightly modded ID values, because the underscore character eliminates the need for a regex:
<div id="parent_1" class="parents"></div>
<div id="parent_2" class="parents"></div>
<div id="parent_3" class="parents"></div>
<div id="child_1"></div>
<div id="child_2"></div>
<div id="child_3"></div>
$("div[id^=parent]").click(function() {
$('#child_' + $(this).attr('id').split('_')[1]).toggle();
});
I also like #Kobi's approach.
Use a class for these divs and use the class selector.
$(".divclass").live ( "click" , function() {
$(this).find("yourchildelementselector").toggle();
});
If its a parent child relation then better put the child divs inside the parent element.
<div id="parent1" class="parent"><div id="child1" class="child"></div></div>
<div id="parent2" class="parent"><div id="child2" class="child"></div></div>
<div id="parent3" class="parent"><div id="child3" class="child"></div></div>
and you can call the click event as
$("div.parent").live ( "click" , function() {
$(this).find("div.child").toggle();
});
