I've created this little example on JSFiddle (http://jsfiddle.net/4UvUv/198/) which allows you to click 3 button and when you click a button, it pushes a value to an array called 'selected'. So lets say I click the 'Cats' button, it will push the value 'cats' to the selected array.
But what I don't know is how to remove 'Cats' from the array if the 'Cats' button was clicked again. Would someone know how to do this using my example? Or if theres a better way?
How I push to the Selected array:
var selected = []
$("#cats").click(function(e) {
console.log("Cats");
var value = 'cats';
selected.push(value);
})
You can try something like this:
$("#cats").click(function(e) {
console.log("Cats");
var value = 'cats';
var index = selected.indexOf(value);
if (index === -1) {
selected.push(value);
} else {
selected.splice(index, 1);
}
});
It can be optimized I think
A much simpler way of achieving this is to only toggle a class on the button elements when you click them. You can then only generate the array when the #results button is clicked. This way you don't need to worry about maintaining the array when items are added/removed. Try this:
$(".button").click(function(e) {
$(this).toggleClass('selected');
});
$("#result").click(function(e) {
var selected = $('.button.selected').map(function() {
return this.id;
}).get();
console.log(selected);
})
.selected {
color: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button class="button" id="cats">Cats</button>
<button class="button" id="dogs">Dogs</button>
<button class="button" id="rabbits">Rabbits</button>
<br />
<button id="result">Result</button>
$("#dogs").click(function(e) {
var index = selected.indexOf("Dogs");
if(index == -1){
console.log("Dogs");
var value = 'Dogs';
selected.push(value);
}else{
selected.splice(index,1);
}
})
try something like this:
var selected = [];
var i = 0;
$("#cats").click(function(e) {
if(i == 0){
console.log("Cats");
var value = 'cats';
selected.push(value);
i++} else {
var check = selected.indexOf('cats');
if(check !== -1){
selected.splice(check, 1);
}
i--;
}
});
Check this solution. you can use indexOf function to know whether the item already exists in the array or not.
var selected = []
$('.buttons').click(function(e) {
var value = $(this).text();
addOrRemove(value);
});
$("#result").click(function(e) {
console.clear();
console.log("results: ", selected);
});
function addOrRemove(item) {
console.clear();
console.log(item);
var index = selected.indexOf(item);
if (index === -1) {
selected.push(item);
} else {
selected.splice(index, 1);
}
}

I browsed thru various similar questions, but I found nowhere real help on my problem. There are some Jquery examples, but none of them weren't applicable, since I want to do it by vanilla JavaScript only.
The Problem
I have rating widget which I want to build like every time I click on "p" element, eventListener adds class "good" on all p elements before and on the clicked one, and remove class good on all that are coming after the clicked one.
My Thoughts
I tried to select all the "p" elements and iterate over them by using a for loop to add class before and on clicked element, and to leave it unchanged or remove after, but somewhere I am doing it wrong, and it adds class only on clicked element not on all previous ones.
My Code
function rating () {
var paragraph = document.getElementsByTagName('p');
for (var i = 0; i < paragraph.length; i++) {
paragraph[i].addEventListener('click', function(e) {
e.target.className='good';
})
}
}
rating();
Result
Expected result is that every p element before the clicked one, including clicked one should be having class good after click and all the ones that are after the clicked one, should have no classes.
Actual Result: Only clicked element is having class good.
Using Array#forEach , Element#nextElementSibling and Element#previousElementSibling
General logic behind this is to loop through all the previous and next sibling elements. For each element, add or remove the class .good until there are no more siblings to handle.
const ps = document.querySelectorAll('p');
ps.forEach(p => {
p.addEventListener("click", function() {
let next = this.nextElementSibling;
let prev = this;
while(prev !== null){
prev.classList.add("good");
prev = prev.previousElementSibling;
}
while(next !== null){
next.classList.remove("good");
next = next.nextElementSibling;
}
})
})
p.good {
background-color: red;
}
p.good::after {
content: ".good"
}
p {
background-color: lightgrey;
}
<div id='rating'>
<p>*</p>
<p>*</p>
<p>*</p>
<p>*</p>
<p>*</p>
</div>
Alternative:
Using Array#slice to get the previous and next group of p's.
const ps = document.querySelectorAll('p');
ps.forEach((p,i,list) => {
p.addEventListener("click", function() {
const arr = [...list];
const previous = arr.slice(0,i+1);
const next = arr.slice(i+1);
previous.forEach(pre=>{
pre.classList.add("good");
})
next.forEach(nex=>{
nex.classList.remove("good");
});
})
})
p.good {
background-color: red;
}
p.good::after {
content: ".good"
}
p {
background-color: lightgrey;
}
<div id='rating'>
<p>*</p>
<p>*</p>
<p>*</p>
<p>*</p>
<p>*</p>
</div>
function setup() {
var paragraph = document.querySelectorAll("p");
for (p of paragraph) {
p.onclick = (event) => {
let index = Array.from(paragraph).indexOf(event.target);
[].forEach.call(paragraph, function(el) {
el.classList.remove("good");
});
for (let i = 0; i <= index; i++) {
paragraph[i].classList.add("good");
}
}
}
}
//Example case
document.body.innerHTML = `
<div id='rating'>
<p>*</p>
<p>*</p>
<p>*</p>
<p>*</p>
<p>*</p>
</div>`;
setup();
The key ingredient is to use Node.compareDocumentPosition() to find out if an element precedes or follows another element:
var paragraphs;
function handleParagraphClick(e) {
this.classList.add('good');
paragraphs.forEach((paragraph) => {
if (paragraph === this) {
return;
}
const bitmask = this.compareDocumentPosition(paragraph);
if (bitmask & Node.DOCUMENT_POSITION_FOLLOWING) {
paragraph.classList.remove('good');
}
if (bitmask & Node.DOCUMENT_POSITION_PRECEDING) {
paragraph.classList.add('good');
}
});
}
function setup() {
paragraphs = [...document.getElementsByTagName('p')];
paragraphs.forEach((paragraph) => {
paragraph.addEventListener('click', handleParagraphClick);
});
}
setup();
#rating { display: flex; }
p { font-size: 32px; cursor: default; }
p:hover { background-color: #f0f0f0; }
.good { color: orange; }
<div id='rating'>
<p>*</p>
<p>*</p>
<p>*</p>
<p>*</p>
<p>*</p>
</div>`
Sorry if this is a silly question, but I'm making something for a site and can't figure this one out.
How can I make this div appear on the first button click, cycle through the array, then disappear after the last item in the array?
var myArray = ["Hello", "Thank you", "Goodbye"];
var myIndex = 1;
var print = document.getElementById('print');
print.innerHTML = myArray[0]; //Print first value of array right away.
function nextElement() {
print.innerHTML = myArray[myIndex++ % myArray.length];
};
#notfound {
background: #2abfffff;
padding: 19px;
margin: 15px;
color: #fff;
}
<div id="notfound">
<p><span id="print"></span>.</p>
</div>
<a id="click" href="#" onclick="nextElement();">Click</a>
JSfiddle: http://jsfiddle.net/jBJ3B/382/
Because you don't want the div to appear before the first click, remove the line with //Print first value of array right away..
One option is to start with an index of -1, make the element visible when the index is 0, and hide the element when the index is higher or equal to the length of the array:
var arr = ["Hello", "Thank you", "Goodbye"];
var index = -1;
var print = document.getElementById('print');
function nextElement() {
index++;
if (index >= arr.length) {
print.style.visibility = 'hidden';
return;
}
if (index === 0) print.style.visibility = 'visible';
print.textContent = arr[index];
}
#notfound {
background: #2abfffff;
padding: 19px;
margin: 15px;
color: #fff;
}
.print {
visibility: hidden;
}
<div id="notfound">
<p><span id="print"></span>.</p>
</div>
<a id="click" href="#" onclick="nextElement();">Click</a>
If you need the element to re-appear on further clicks, then use modulo to set index to -1 at the end:
var arr = ["Hello", "Thank you", "Goodbye"];
var index = -1;
var print = document.getElementById('print');
function nextElement() {
index++;
if (index >= arr.length) {
print.style.visibility = 'hidden';
index = -1;
return;
}
if (index === 0) print.style.visibility = 'visible';
print.textContent = arr[index];
}
#notfound {
background: #2abfffff;
padding: 19px;
margin: 15px;
color: #fff;
}
.print {
visibility: hidden;
}
<div id="notfound">
<p><span id="print"></span>.</p>
</div>
<a id="click" href="#" onclick="nextElement();">Click</a>
You can check inside nextElement() if that element was the last one, and then just hide the div.
function nextElement() {
print.innerHTML = myArray[myIndex++%myArray.length];
if(myIndex>myArray.length){
document.getElementById("notfound").style.visibility = "hidden";
}
};

Is it what you trying to do:http://jsfiddle.net/yvbenitah/jBJ3B/393/.
If yes only add that line:
document.getElementById('notfound').style.display = 'none';
Can Push() and Pop() and Image Replacement Work within an Array?
8th Gr math teacher attempting to create a slide show of question images that pop() and push() through an image array based on student responses. If the student answers correctly the question is popped, but if they answer incorrectly it is added to the end of the queue. Additionally, since deleting elements in the DOM is bad, I am replacing the current image's src and id with that of the next element in queue. The array is then popped and pushed along, but whenever I enter in the incorrect answer twice the same image appears.
I have moved the global variable that holds the array, domEls, inside of the function retrieveAnsForImage to force it to randomize the images in the array. When I do this, the images change correctly so I believe it is the push() and pop() commands.
I included a snippet that doesn't work here, but works like a champ in Notepad ++. I just took a crash course in Javascript, HTML and CSS last month on Codecademy, I am very new to this. Thank you for reading.

Your issue is that pop removes the last element from the array while push adds the element to end of the array.
What you probably want to do is use shift to remove the the first element from the array and pop it back to the end if the answer is wrong.
Alternately, you could pop the last element and use unshift to insert back into the beginning of you want to work in the other direction.
Here's a quick mockup without images.
var currentTest = null;
function getTest() {
$('#answer').html("").hide();
if (tests.length > 0) {
currentTest = tests.shift(); // remove the first question
$('#question').fadeIn(450).html(currentTest.q);
return currentTest;
} else {
$('#answer').html("Finished").fadeIn(500);
$('#btnCorrect').unbind();
$('#btnWrong').unbind();
}
}
var tests = [];
for (var i = 0; i < 5; i++) {
var question = "Question " + i;
var answer = "Answer " + i;
tests.push({
q: question,
a: answer
});
}
$('#btnCorrect').click(function() {
$('#question').hide();
$('#answer').fadeIn(450).html("Correct!");
window.setTimeout(getTest, 750);
});
$('#btnWrong').click(function() {
$('#question').hide();
tests.push(currentTest); // put the question back in the array
$('#answer').fadeIn(450).html("Incorrect!");
window.setTimeout(getTest, 750);

I have a script that shows the amount of clicks on a button and I want to change the background image of another div after a certain amount of clicks, in this case 5. At the moment the click amount works fine but the other part wont react to it. The second code works if I manually type 5 as the starting value for #click.
This is what I have so far:
$('#button').click(function () {
$('#clicks').html(function (i, val) {
return val * 1 + 1
});
});
if ($('#clicks').html() == 5) {
$("#first").addClass('red');
}
<div id="clicks">0</div>
<div id="first">first</div>
<div id="button">click</div>
#first {
width: 100px;
height:100px;
}
.red {
background:red;
}
You need to check the value after each click modification. also you should compare the returned value with string:
$('#button').click(function () {
$('#clicks').html(function (i, val) {
return val * 1 + 1
});
//check for new value
if ($('#clicks').html() == "5") {
$("#first").addClass('red');
}
});
Try this:
$(function() {
var count = 0;
$('div').click(function() {
if (count++ == 5) {
$(this).addClass('red');
}
})
});
.red {
background-color: red;
}
div {
width: 100px;
height: 100px;
background-color: blue;
}
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<div></div>
Increase the value and check if it's 5 within the click function.
$('#button').click(function () {
$('#clicks').html(function (i, val) {
val++;
if (val == 5)
$("#first").addClass('red');
return val;
});
});
You can also change it every 5 clicks by using the modulus and toggleclass.
$('#button').click(function () {
$('#clicks').html(function (i, val) {
val++;
if (val % 5 == 0)
$("#first").toggleClass('red');
return val;
});
});
So, i want to make game for my child. Have low experience in JS.
Scenario:
Have for example 4 square divs with blank bg. After refresh (or win) i want to:
Generate random numbers into div (1...4). And show them in them.
Then let player delete those divs by clicking on them, but in sequence how divs are numbered.
*For example after refresh divs have those numbers 2 3 1 4. So, user has to have rights to delete first div numbered 1 (2 3 _ 4) and so on.* If he clicks on 2 it get error , div stays in place, and user can try again delete right one.
It game for learning numbers. I have the begining.

There are a few things you have to do. First you have to create a random array which you use sort and Math.random() to do then, you need insert the text in the squares. Find the min of the visible squares and then remove/alert depending if its the min value.
// sort by random
var rnd = [1,2,3,4].sort(function() {
return .5 - Math.random();
});
// map over each div in the grid
$('.grid div').each(function(ii, div) {
$(div).text(rnd[ii]); // set the text to the ii'th rnd
});
function minVisible() {
var min = 1e10; // a big number
$('.grid div').each(function(ii, div) {
// if not visible ignore
if ($(div).css('visibility') === "hidden" ){
return;
}
// if new min, store
var curFloatValue = parseFloat($(div).text());
console.log(curFloatValue);
if (curFloatValue < min) {
min = curFloatValue;
}
});
return min;
}
$(".grid").children( "div" ).on("click", function(){
var clickedFloatValue = parseFloat($(this).text());

}
});
Updated jsfiddle http://jsfiddle.net/bNa8Z/2/
Roughly this is what it would look like:
var selected = {};
$('.grid div').each(function(idx){
var is_done = false;
do{
var rand = Math.floor((Math.random()*4)+1);
if( selected[rand] == undefined ){
$(this).html(rand);
selected[rand] = 1;
is_done = true;
}
}while(!is_done);
});
alert("Start the game");
var clicked = [];
$('.grid').on('click', 'div.block', function(){
var num = $(this).html();
if( num == clicked.length + 1 ){
//alert(num + " is correct!");
clicked.push(num);
$(this).addClass("hide");
}else{
alert("Failed!");
}
if( clicked.length == 4 ){
alert("You Won!");
}
});
HTML:
<div class="grid">
<div class="block" id="Uleft"></div>
<div class="block" id="Uright"></div>
<div class="block" id="Dleft"></div>
<div class="block" id="Dright"></div>
</div>
Added CSS:
#Uleft, #Uright, #Dleft, #Dright {
position:absolute;
...
}
#Uright {
left:220px;
top:0px;
background-color: red;
}
#Uleft {
left:0px;
top:0px;
background-color: blue;
}
#Dleft {
left:0px;
top:220px;
background-color: green;
}
#Dright {
left:220px;
top:220px;
background-color: yellow;
}
.hide {
display: none;
}

You will need to re-"run" the fiddle per game.
please try it. I think that It will help you.
