Execute function if the element was not selected before - javascript

When the the div with .redactor class is clicked, check if it is already as the selected element.
If it is already selected then do nothing.
If it is newly selected then
Execute the initialize_redactor() for that current selected div,
And execute the destroy_redactor() if there was any div which was previously selected.
And while any of the .redactor div is selected, if clicked other than the .redactor div, then execute destroy_redactor() for the currently selected .redactor div.
Sample in codepen.io
html:
<div id="toolbar_wrapper">
<div id="toolbar">
</div>
</div>
<div id="content">
<div class="redactor">
<h1>Header</h1>
<p>Paragraph</p>
</div>
<div class="redactor">
<h1>Another Header</h1>
<p>Another Paragraph</p>
</div>
</div>

You should loop through every ".redactor" element and run destroy_redactor on the selected element:
$('.redactor').on("click", function() {
$(".redactor").each(function () {
if($(this).hasClass("selected"))
{
destroy_redactor(current_edit);
$(this).removeClass("selected");
}
});
$(this).addClass("selected");
current_edit = $(this);
initialize_redactor(current_edit);
});

I think you just need to add two more lines to your js
You will destroy ALL .selected AFTER you check if the redactor has a class of selected:
if (!$(this).hasClass("selected")) {
destroy_redactor($('.selected'));
Then, if it already has the class selected, remove that class
} else {
$('.selected').removeClass('selected');
Here's the codepen to try it out:

Jquery text() doesn't work outside chrome console

I have this small piece of code
HTML
<div class="select">
<p></p>
</div>
<div class="option">
<p class="active">text</p>
</div>
JS
$('.option p').click(function() {
if ($(this).hasClass('active')) {
$(this).removeClass('active');
if ($('.option p.active').length == 0) {
$('.select p').text('some text');
}
}
})
If I run this code in the chrome console, it works perfectly. But if I run it in my programme, it doesn't work (the .select p text is not changed). I tried putting an alert() after text() to see if it would execute, and apparently alert() is executed, so text() should also be executed. I don't understand why it is not being executed in my programme (it was working perfectly a few weeks ago)
You need to put the code inside a click handler. When you click on an element, do different things depending on whether you clicked on the active or inactive element.
If it's active, remove the class and put the default text in the select paragraph.
If it's not active, remove the class from all the other elements and add the class to this element, and display its text in the select paragraph.
$(".option p").click(function() {
if ($(this).hasClass("active")) {
$(this).removeClass("active");
$(".select p").text("No option selected");
} else {
$(".option p").removeClass("active");
$(this).addClass("active");
$(".select p").text($(this).text());
}
});
.option p.active {
background-color: yellow;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="select">
<p>text 1</p>
</div>
<div class="option">
<p class="active">text 1</p>
</div>
<div class="option">
<p>text 2</p>
</div>
<div class="option">

Select items from different lists at the same time

This is the HTML I got to do a button click event to control selected items in more than one list.
$('#button').click(function(){
var $next = $('.section.selected').removeClass('selected').next('.section')
if ($next.length) {
$next.addClass('selected');
}
else {
$(".section:first").addClass('selected');
}
});
//On click I select next div with same class and remove selected from previous.
//How to loop? After 3 is selected, I want it to go to one again.
.selected { background:red }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="all">
<div class="section selected">ONE</div>
<div class="section">TWO</div>
<div class="section">THREE</div>
</div>
<div id="all">
<div class="section selected">ONE</div>
<div class="section">TWO</div>
<div class="section">THREE</div>
</div>
<br />
CLICK
However, because the items are using the same class name, at the end, the script can't decide which one is first / last item.
Can anyone give me an idea?
To get the items, use Queries like first-child, last-child and so on.
For more detals, Check jQuery API Documentation
Use this instead $(".section:first-child").addClass('selected') in your else condition

Child div affects parent div in css and triggers jquery method

I have parent div with class a "very-big-div" that nests another "container-div" that by its turn also nests another child divs. The very big div's made to act like a button and the div that come right after it is a container that appears when I click the very big div.
<div class="very-big">
<div class="container">
<!-- Some other more nested divs that has anchors and buttons -->
<div class="friend-request">
<div class="button-div">
<button class="accept">Trigger</button>
<button class="refuse">Trigger</button>
</div>
</div>
</div>
</div>
The problem is 2 things first: the css problem has not yet been solved
I assigned a hover pseudo class for the "very-big-div", and whenever I hover the "container-div" the hover properties(background-color) is applied to the "very-big-div". This is not what I intend to make, I want to only hover "very-big" div for the hover to apply.
.very-big{
background-color:green;
}
The second problem is : I have a jquery that deals with the container so it is toggled on/off by the "very-big-div"
$(document).ready(function(){
$("#container-div").hide();
$("#very-big-div").click(function(){
$("#container-div").toggle();
});
});
the container has both anchor and button tags whenever I click the an anchor or a button inside the container it is toggled to close itself, and that is not what I want, what I want is just when I only press the "very-big-div" the toggle is activated.
Same as #Jhecht has given the answer, I have just inherited his to mine.
You can stop propagation of the click of child element that trigger toggle by using target and excluding all the child elements of your .very-big container as:
$(".very-big").click(function(e) {
var target = $(e.target);
if (!target.is('.very-big *')) {
$(".container").toggle();
}
});
Code Snippet:
$(document).ready(function() {
$(".container").hide();
$(".very-big").click(function(e) {
var target = $(e.target);
if (!target.is('.very-big *')) {
$(".container").toggle();
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="very-big">
Other Text
<div class="container">
This is text to fill stuff out so I can click on it.
</div>
</div>
This works for me, but I am not sure if it is what you need.
Please add in the minimum HTML, CSS, and Javascript needed to fully recreate the error you are seeing.
$(document).ready(function() {
$(".container").hide();
$(".very-big").click(function(e) {
console.log(e);
var current = $(e.toElement);
if (current.is('.container')) {
e.stopPropagation();
return false;
}
$('.container').toggle();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="very-big">
Other Text
<div class="container">
This is text to fill stuff out so I can click on it.
</div>
</div>

Replace the same class div and has no ID

I have four DIVS, one is ready and the other three are still hidden. When the link to the second div is pressed, I want the second div to show up, and so for the next link.
The problem is, all the four DIV doesn't have ID and has the same class.
I just want it to automatically run without knowing what is the ID and the class of the div, or anything inside the div. It may look like a slideshow but on click function.
<p> link to the ready div </P>
<p> link to the second div </P>
<p> link to the third div </P>
<p> link to the last div </P>
<div id="wrapper">
<div> this is the div that is ready. This div has no ID and has the same class with others <div>
<div> this is the second div that is hidden. This div has no ID and has the same class with others <div>
<div> this is the third div that is hidden. This div has no ID and has the same class with others <div>
<div> this is the last div that is hidden. This div has no ID and has the same class with others <div>
</div>
FIDDLE
i have made a fiddle that might suite your case please have a look. You can make some modifications according to your needs.
var currentDiv = 0;
$(document).ready(function(){
$(".container div").click(function(){
$(".container div").eq(currentDiv+1).css( "display", "block" );
currentDiv++;
})
});
JSFIddle Link
Im pretty sure this is what you are looking for.
jQuery
$(".options p").click(function () {
var ourPick = $("p").index(this) + 1;
$(".container div:nth-child(" + ourPick + ")").show();
});
Demo Here
So what we are doing is getting the index for the link pressed and then using that to select the div we want to show (this is using :nth-child()).
Note: I have put a container around the links so you it doesn't pick up every p on the page.
If you want only one at a time you can just set them all to hide before showing one.
jQuery:
$(".options p").click(function () {
var ourPick = $("p").index(this) + 1;
$(".container div").hide();
$(".container div:nth-child(" + ourPick + ")").show();
});
Demo Here
JS FIDDLE DEMO
Explanation
<div class="parentDiv">
<div class="div">1</div>
<div class="div">2</div>
<div class="div">3</div>
<div class="div">4</div>
</div>
<div class="buttons">
<a idx="1">1</a>
<a idx="2">2</a>
<a idx="3">3</a>
<a idx="4">4</a>
</div>
$('.buttons a').click(
function(event)
{
var idx = $(event.target).attr('idx');
$('.div').hide(); //Hides all the divs
$('.parentDiv div:nth-child('+idx+')').show(); // Shows required div
}
);
DISADVANTAGE
If you will insert more contents, there is more work. Else no problem..
If you insert a div , you have to change all the links.
<div class="parentDiv">
<div class="div">1</div>
<div class="div">2.0 Inserted Div</div>
<div class="div">2</div>
<div class="div">3</div>
<div class="div">4</div>
</div>
<div class="buttons">
<a idx="1">1</a>
<a idx="2">2.0</a>
<a idx="3">2</a>
<a idx="4">3</a>
<a idx="5">4</a>
</div>
Not here , All the idx has to be changed. Since my code uses nth-child property

Traversing DOM from span in / out of divs

I'm adding a click event to a span that is within a div. The target of this event, which will become visible, is a first div that is within a div, two divs down. How can I traverse the DOM to find it?
Perhaps it'll be clearer with the code:
<div a>
<h2>
<span id="here">Click</span>
</h2>
</div>
<div></div>
<div>
<div class="targetDiv">This is the div we need to find</div>
<div class="targetDiv">There are other divs with the same id, but we don't need to find those</div>
<div class="targetDiv">Not looking for this one </div>
<div class="targetDiv">Or this one either</div>
</div>
I've searched left and right and cannot find an answer. It's important to restrict the event ONLY to the first div immediately after the span.
Any help would be much appreciated.
As shown, the code would look like this:
$('span#here').on('click', function() {
$(this).closest('div').siblings(':contains(.targetDiv)').children().eq(0).show();
}
Here's a sample of the fish we caught
$(function() {
$('#here').on('click', function() {
var div = $(this) //the element clicked
.closest('div') //find nearest parent div
.nextAll(':eq(1)') //find the second next div
.children(':eq(0)') //find the first child of it
.show(); //remove invisible cloak
});
});​
This works. I provided an example you can just save to a html file and test it yourself
<style>
.targetDiv{display:none;}
</style>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(){
$('#here').click(function(){
$('.targetDiv').first().show(); // or whatever you want
});
});
</script>
<div a>
<h2>
<span id="here">Click</span>
</h2>
</div>
<div></div>
<div>
<div class="targetDiv">This is the div we need to find</div>
<div class="targetDiv">There are other divs with the same id, but we don't need to find those</div>
<div class="targetDiv">Not looking for this one </div>
<div class="targetDiv">Or this one either</div>
</div>
