how can I check if it was the last div? If it was I need to remove all classes "ready"
html:
<div class="green"></div>
<div class="orange"></div>
<div class="red"></div>
<div class="green"></div>
<div class="orange"></div>
js:
$(function() {
setInterval(showBlock, 1000);
function showBlock() {
var x = $("div:first").addClass("ready");
var c = $("div");
$(".ready").css("display", "block");
if (c.hasClass("ready")) {
$(".ready:last").next().addClass("ready");
}
}
})
;
Looking at your code what I understand is you want display one div after each second. For that I'll suggest following approach.
First add hidden class to all divs and then remove it from first hidden div at each second.
$(function() {
$('div').addClass('hidden');
var i = setInterval(showBlock, 1000);
function showBlock() {
var x = $("div.hidden:first").removeClass("hidden");
if($("div.hidden").length == 0) {
clearInterval(i);
}
}
});
.hidden {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="green">Green</div>
<div class="orange">Orange</div>
<div class="red">Red</div>
<div class="green">Green</div>
<div class="orange">Orange</div>
As far as I understand your problem, following solution must work in your case:
$(function() {
setInterval(showBlock, 1000);
function showBlock() {
var ready_divs = $("div.ready").length;
var total_divs = $("div").length;
if(ready_divs!=total_divs){
if(ready_divs==0){
$("div:first").addClass('ready');
}else{
$("div.ready:last").next('div').addClass('ready');
}
}else{
$("div").removeClass('ready')
}
}
});
div{
width: 20px;
height: 20px;
border:1px solid red;
}
div.ready{
border:3px solid blue;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="green"></div>
<div class="orange"></div>
<div class="red"></div>
<div class="green"></div>
<div class="orange"></div>

I am trying to wrap my head around prototype in javascript as well as getting used to the value of this. Currently I have this set to .cf--modal but when I use this to set a variable it does not seem to work. As this is my first of many functions I really don't want to hit the document and would rather target "this" within the Modal Toggle function.
How can I change the modal_toggle function so that document.getElementById and document.getElementsByClassname can be replaced with this.find or something along those lines.
$(function(){
$('.cf--modal').each(function(){
let cf = new ContactForm($(this));
});
});
var ContactForm = function(this$obj){
this.$obj = this$obj;
this.init();
}
ContactForm.prototype.init = function init(){
this.modal_toggle();
};
ContactForm.prototype.modal_toggle = function modal_toggle(){
let cfCTA = document.getElementsByClassName("modal-trigger")[0];
let cfModal = document.getElementsByClassName("cf--modal")[0];
let cfModalClose = document.getElementsByClassName("close-cf-modal")[0];
cfCTA.onclick = function () {
cfModal.style.display = "block";
}
cfModalClose.onclick = function(){
cfModal.style.display = "none";
}
}
.cf{
width:1000px;
margin:40px auto;
}
.inner-container{
padding:12px 24px;
border:1px solid grey;
border-radius:5px;
display:flex;
align-items:center;
justify-content:center;
}
.cf-block{
flex:1
}

You should use this.$obj to refer to the modal element for the current ContactForm
ContactForm.prototype.modal_toggle = function modal_toggle() {
let cfModal = this.$obj;
let cfCTA = $(".modal-trigger");
let cfModalClose = cfModal.find(".close-cf-modal");
cfCTA.on("click", function() {
cfModal.show();
})
cfModalClose.on("click", function() {
cfModal.hide();
});
}
I need a if else function that checks if div_container has more than one div_inner inside of it with Javascript only.
Here's my example code:
var inner = document.querySelector('.inner')
var container = document.querySelector('.container').innerHTML;
if(container > '1') {
container.classList.add('test');
}
else {
// do nothing
}
.test {
color: red;
}
<div class="container">
<div class="inner">Test</div>
</div>
<div class="container">
<div class="inner">Test</div>
<div class="inner">Test</div>
</div>
I only want to use Javascript. No jQuery at all.
You have to use querySelectorAll() to get all the container and loop through them to check the inner div's length:
var container = document.querySelectorAll('.container');
container.forEach(function(el){
var inner = el.querySelectorAll('.inner').length;
if(inner > 1) {
el.classList.add('test');
}
else {
// do nothing
}
});
.test {
color: red;
background-color: lightgray;
}
<div class="container">
<div class="inner">Test</div>
</div>
<div class="container">
<div class="inner">Test</div>
<div class="inner">Test</div>
</div>
You can use querySelectorAll()
for (const container of document.querySelectorAll('.container')) {
if (container.querySelectorAll('.inner').length > 1) {
container.classList.add('test');
}
}
.test {
color: red;
}
<div class="container">
<div class="inner">Test</div>
</div>
<div class="container">
<div class="inner">Test</div>
<div class="inner">Test</div>
</div>
I have painted my self into a corner in order to quickly prototype.
What's the best way to refactor the following jQuery code? Its functionality is to toggle between some sidebar navigation items. I need it to be more dynamic in order to be scalable.
Would you add the IDs inside the if statements, in an array and iterate through them? Use variables? Create a function and call it on the html side onClick? No matter what I think of, it stills leads to a bunch of repeating code.
Thank you!

You should group using the common CSS class, i.e. header and content. Using the established relationship you can target the others content holder and content associated with the current clicked header element.
$('.container .header').on('click', function() {
//Get the current element
var $this = $(this);
//find the content
var $content = $this.closest('.container').find('.content'); //$this.next()
//get all contents
var content = $('.container .content');
//Slide up others
content.not($content).slideUp(350);
//Slide down
$content.slideToggle(350);
});
.content {
display: none
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<div class="header" id="settingsClick">Click Me</div>
<div class="content" id="settingsContainer">Content...</div>

<div class="container">
<div class="header" id="addClick">Click Me</div>
<div class="content" id="addContainer">Content...</div>
</div>
<div class="container">
<div class="header" id="noteClick">Click Me</div>
<div class="content" id="noteContainer">Content...</div>
</div>
the best bet would be to do it like so
$(document).on('click', ".trigger", function() {
var sibling_content = $(this).siblings(".content");
if (!sibling_content.hasClass('active')) {
$(".content").slideUp('slow').removeClass('active');
sibling_content.slideDown('slow').addClass('active');
} else {
sibling_content.slideUp('slow').removeClass('active');
}
})
.trigger {
background-color: red;
color: white;
font-size: 16px;
}
.content {
background-color: blue;
color: white;
font-size: 16px;
padding: 20px 0;
display: none;
}

Here is jsfiddle of raw code and the result should be like this
<div class="wrapper">
<div class="row">
<div class="col red">R</div>
<div class="col blue">B</div>
<div class="col green">G</div>
<div class="col orange">O</div>
</div>
</div>
The mission is: Last color of previous row should be the first in next row and first color from previuos row should be the second in next row.
I think that I have to use loop and recursion but I don't have enough knowledge to do this.
Thanks in advance :)
You can run through the for loop and do something like this
check this snippet
//last color of previous row should be first in next row
//first color from previous row should be second in next row
var colors = ['red', 'blue', 'green', 'orange'];
$(document).ready(function() {
var rows = $('.row');
rows.each(function(row) {
var index = $(this).index();
var prevRow;
if (index > 0)
prevRow = $(this).prev();
colorColumns($(this).find('.col'), prevRow);
});
});
function colorColumns(cols, prevRow) {
var index = 0;
// alert("hi");
cols.each(function(col) {
var colIndex = $(this).index();
if (prevRow) {
var cols = prevRow.find('.col').length;
var totalCols = cols - 1;
var currentIndex = ((colIndex + totalCols) % cols);
var prevRowColor = $(prevRow).find('.col').eq(currentIndex);
var classes = prevRowColor.attr('class');
var classArr = classes.split(" ");
$(this).addClass(classArr[1]);
} else {
$(this).addClass(colors[colIndex]);
}
});
}

display: flex;
}
.row .col {
width: 20px;

I am trying to swap a div's position from top on and when I click another div then top div can be swap.
HTML
<div class="wrap top">
<input type="text" value="div1" class="textbox " />
</div>
<div class="wrap">
<input type="text" value="div2" class="textbox " />
</div>
<div class="wrap">
<input type="text" value="div3" class="textbox " />
</div>
jQuery
(function ($) {
$(".wrap").on("click", function () {
if ($(this).index() == 0) {
} else {
$(this).insertBefore($(this).prev());
}
});
}(jQuery));
The fact is I don't want to remove the div which I click instead want to swap the positions around.
How Can I do this using jQuery itself?
I would suggest using css to position the top div and just swap the class as follows:
(function ($) {
$(".wrap").on("click", function () {
if ($(this).index() == 0) {
} else {
$(".wrap").removeClass("top");
$(this).addClass("top");
}
});
}(jQuery));
this will swap whatever you click with the first element.
$(".wrap").on("click", function () {
var $this = $(this);
if ($this.index() == 0) {
} else {
var first = $this.siblings('.wrap').first();
first.insertBefore($this);
$this.prependTo($this.parent());
}
});
if you just want to move the clicked element to the top, you can simply do
$this.prependTo($this.parent());
To swap the two DOM elements using jQuery, you could use something like this: -
(function($) {
$(".wrap").on("click", function(event) {
var index = $(event.target).index();
var first = $(".wrap").first();
if (index > 0) {
$(first).swapWith(this);
}
});
}(jQuery));
jQuery.fn.swapWith = function(to) {
return this.each(function() {
var copy_to = $(to).clone(true);
var copy_from = $(this).clone(true);
$(to).replaceWith(copy_from);
$(this).replaceWith(copy_to);
});
};
.wrap {
height: 100px;
width: 200px;
margin: 10px 10px 10px 10px;
background-color: #2d8cd0;
}
h2 {
color: white;
text-align: center;
padding-top: 20px;
pointer-events: none;
}
