repeat putting input element randomly between user's text

I have a text element that is built when the user clicks a button. In the middle of that text, I added an input element.I want to make this process repeats seven times but it looks complicated. I actually made a lot of things but here are the important ones So, First I made an input element and a button when the user enter input and click the button what he wrote will be displayed in a h1 element with a random missing word Then,I made an input element in the that the missing word should've been in.What I want is that this to repeat this process seven times.
function myFunction() {
var x = document.getElementById("input").value;
x = x + " ";
var y = document.getElementById("inputed");
var a,b = "c";
const c=[];
const d=[];
var e;
var f = 0;
const array = [];
const z = x.length;
for (let index = 0; index < 7; index++) {
a= "c";
b= "c";
c.push(0);
d.push(0);
c[index] = 0;
d[index] = 0;
e = 1;
f = 0;
//Here the program will get a random space location and the space after it
while (a != " ") {
c[index] = Math.floor(Math.random() * x.length - 2);
a = x.charAt(c[index]);
}
d[index] = c[index];
//The variable d will be the same as c and will increase until its value corrspends to a space
while (b != " ") {
d[index]++;
b = x.charAt(d[index]);
}
//I want the y.innerHTML to write from the 0 to c[0] then display the input element then from d[0] //to c[1] and display the input element again and form d[1] to c[2] until 7
y.innerHTML = `${x.slice(
0,
c[0]
)}<input type="text" style="color: gray;border:2px solid;border-radius: 10px;outline: none;
font-size: x-large;height:40px;width: 100px;" >${x.slice(d[0], z)} `;
}
}

I had problems understanding perfectly your code so I couldn't answer trying to address the exact problems affecting your specific algorithm.
Anyway I made an attempt trying to understand your description and as far as I could get I tried to implement a demo beginning from a input text filled by the user and:
When the button PARSE SENTENCE gets clicked, the procedures parses the
input text splitting its content by white spaces to find out the
words.
Then it determines how many random words he wants to "remove" from
the string and at which index.
Then it creates a span element for each of those words and put all of them
in a separate array
Such spans, will have the word in their innerText, the default class
word and an added class that will be kept-word if that's a word not
to remove and removed-word otherwise. Plus they will keep track of that original word inside a data attribute called data-original
Those spans get appended to the #transformed element, and at this
stage, if the word belongs to the class .removed-word its
innerText gets emptied and its contenteditable attribute
activated.
In the end, after the parsing of the sentence, the exact spans code
will be shown in the <pre> element to give evidence of what's going
on
I know it's very far from what you have asked.. considering I didn't strictly stressed the algorithm aspect and mostly used shortcut like split, includes, contains and more importantly I totally changed your logics and used spans for words parsed and didn't use the input at all but contenteditable.
I sincerely hope it will anyway give some inspiration
function transform(){
const input = document.getElementById('input').value.trim();
const words = input.split(" ");
const nrOfWordsToReplace = Math.floor(Math.random() * words.length);
const indexesOfWordsToReplace
= Array.from({length: nrOfWordsToReplace}, () => {
return Math.floor(Math.random() * words.length);
});
//for each word in the input, create a span element to add in #transformed
//words expected to be kept will have their span with class .word.kept-word
//words expected to be removed will have their span with class .word.remove-word
let index = 0;
const outputWords = [];
for(word of words){
if( indexesOfWordsToReplace.includes(index) ){
const outputWord = createOutputWordElement(word, 'removed-word');
outputWords.push( outputWord );
}else{
const outputWord = createOutputWordElement(word, 'kept-word');
outputWords.push( outputWord );
}
index++;
}
const codeContainer = document.querySelector('pre');
codeContainer.innerHTML = '';
//clear its content appends those spans to #transform
const transformed = document.getElementById('transformed');
transformed.innerHTML = '';
for(outputWord of outputWords){
if (outputWord.classList.contains('removed-word')){
outputWord.innerText = '';
outputWord.contentEditable = true;
}
transformed.append(outputWord);
const code = document.createElement('code');
code.innerText = outputWord.outerHTML;
codeContainer.append(code);
}
}
//returns a span element having the word as content and classname among its classes
function createOutputWordElement(word, classname){
const outputWord = document.createElement('span');
outputWord.classList.add('word');
outputWord.classList.add(classname);
outputWord.dataset.original = word;
outputWord.innerText = word;
return outputWord;

progressbar html tag change

I'am working on progressbar that change the level when reaching some point.
The code.
I want to change the text under the progressbar when the progressbar reach 100 or above 90.
I could change it once but I want to go to next level, like this.
silver ==> gold ==> diamond ==> and more
const step = 5;
var content=document.getElementById('mylevel').innerHTML;
const updateProgress = () => {
const currentWidth = Number(document.getElementById("progressvalue").style.width.replace( "%", ""));
if (currentWidth>=100) {
return;
}
else {
document.getElementById("progressvalue").style.width = `${currentWidth+step}%`;
}
if (currentWidth > 90) {
document.getElementById("mylevel").textContent = "gold";
document.getElementById("progressvalue").style.width = "0%";
}
if (currentWidth > 90 && content == "gold") {
document.getElementById("mylevel").textContent = "diamond";
document.getElementById("progressvalue").style.width = "0%";
}
}
const restart = () => {
document.getElementById("progressvalue").style.width = "0%";
}
.progress {
background-color: #ededed;
width: 100%;
overflow: hidden;
}
#progressvalue {
height: 40px;
background-color: lightgreen;
width: 0%;
}
<div class="progress">
<div id="progressvalue"></div>
</div>
<p id="mylevel">silver</p>
<br />
<button type="button" onclick="updateProgress()">
Update Progress
</button>
<button type="button" onclick="restart()">
Restart
</button>
When the updateprogress is above 90 the silver change to gold, but I need to change again to diamond when the updateprogress is again above 90.
Am I putting the if condition in a wrong place, I tried many times.
I don't know what I'am missing and am new with JavaScript
I started the code but got help here to make it much better (80% of the code done by
teresaPap thanks)

Update
After closer inspection it is an issue of content not updating you need to put it inside updateProgress() or it will forever remain the initial value.
const step = 5;
const updateProgress = () => {
var content = document.getElementById('mylevel').innerHTML;
//the rest of the code
I do however recommend you to improve your if statements. You only need one if for this task.
A better solution
A better solution would be something like this:
Add a hidden value to keep your level progress
</div>
<p id="hiddenlevel">0</p>
<p id="mylevel">silver</p>
<br />
and css:
#hiddenlevel {
height: 0px;
visibility: hidden;
width: 0%;
}
now that you have a hidden value you can wrap up all future ifs in a single one.
const levels = ["silver", "gold", "diamond"]
var mylevel = Number(document.getElementById("hiddenlevel").innerHTML);
if(currentWidth > 90 && mylevel < levels.length){
document.getElementById("hiddenlevel").textContent = mylevel + 1;
document.getElementById("mylevel").textContent = levels[mylevel + 1];
document.getElementById("progressvalue").style.width = "0%";
}
and just like that you can just add a new level inside the levels array and it will be added without issues.
Update 2
Just noticed I made a mistake!
You don't need a hidden element for this: you might end up having to use hidden elements when using plugins, but it was completely unnecessary here :)
Updated code:
const step = 5;
var mylevel = 0;
const updateProgress = () => {
const currentWidth = Number(document.getElementById("progressvalue").style.width.replace( "%", ""));
if (currentWidth>=100) {
return;
}
else {
document.getElementById("progressvalue").style.width = `${currentWidth+step}%`;
}
const levels = ["silver", "gold", "diamond"];
if(currentWidth > 90 && mylevel < levels.length){
mylevel = mylevel + 1;
document.getElementById("mylevel").textContent = levels[mylevel];
document.getElementById("progressvalue").style.width = "0%";
}
}
const restart = () => {
document.getElementById("progressvalue").style.width = "0%";
}
.progress {
background-color: #ededed;
width: 100%;
overflow: hidden;
}
#progressvalue {
height: 40px;
background-color: lightgreen;
width: 0%;
}
<div class="progress">
<div id="progressvalue"></div>
</div>
<p id="mylevel">silver</p>
<br />
<button type="button" onclick="updateProgress()">
Update Progress
</button>
<button type="button" onclick="restart()">
Restart
</button>

Comprobating function not working as it should

I need to create a lottery game. I have an idea of how the whole code should be and it's mostly done, but I have a problem:
I have a button with an onclick called generar(), and this function, needs to draw 3 numbers from 1 to 999 and create along with the three numbers, another button which after pressing it, draws another number and then (the new button) checks the new number number with the ones who are already created to see if I won, or not.
Okay, I've managed to do the whole code, but the comparison of the three first numbers with the fourth number, doesn't work correctly. Always, the comprobation which says if I won or not, writes "¡Perdedor!" (looser!).
This is my code:
<html>
<head>
<title>Práctica 3</title>
<style>
#contenedor { border: 1px black solid;
width: 250px;
height: 250px;
float: left;
margin-right: 5px;
text-align: center;
margin-bottom: 5px; }
</style>
</head>
<body>
<div id="contenedor"> <p id="primerNumero"/> </div>
<div id="contenedor"> <p id="segundoNumero"/> </div>
<div id="contenedor"> <p id="tercerNumero"/> </div>
<button id="generar" onclick="generar()">Genera dècims</button>
<div id="contenedor"> <p id="resultado"/> </div>
<p id="t"/>
<script>
function generar() {
var primerNumero = Math.floor(Math.random() * 10);
var segundoNumero = Math.floor(Math.random() * 10);
var tercerNumero = Math.floor(Math.random() * 10);
var botones = document.getElementsByTagName("BUTTON").length;
if (botones < 2) {
generarBotones();
}
document.getElementById("primerNumero").innerHTML = primerNumero;
document.getElementById("primerNumero").style.fontSize = "72px";
document.getElementById("segundoNumero").innerHTML = segundoNumero;
document.getElementById("segundoNumero").style.fontSize = "72px";
document.getElementById("tercerNumero").innerHTML = tercerNumero;
document.getElementById("tercerNumero").style.fontSize = "72px";
}
function generarBotones() {
var boton = document.createElement("BUTTON");
var t = document.createTextNode("Realizar sorteig");
boton.onclick = function(){
var numeroGanador = Math.floor(Math.random() * 10);
document.getElementById("resultado").innerHTML = numeroGanador;
document.getElementById("resultado").style.fontSize = "72px";
if(primerNumero == numeroGanador || segundoNumero == numeroGanador || tercerNumero == numeroGanador) {
document.getElementById("t").innerHTML = "¡Ganador!";
} else {
document.getElementById("t").innerHTML = "¡Perdedor!";
}
};
boton.appendChild(t);
document.body.appendChild(boton);
}
</script>
</body>
</html>
If somebody can tell me why and where I fail and a possible solution, it will be great. I will very grateful if an explanation is given too

primerNumero
segundoNumero
tercerNumero
Are html elements, not value, to get the value is necessary to use innerText OR innerHTML.
if(primerNumero.innerText == numeroGanador || segundoNumero.innerText == numeroGanador || tercerNumero.innerText == numeroGanador) {
document.getElementById("t").innerHTML = "¡Ganador!";
} else {
document.getElementById("t").innerHTML = "¡Perdedor!";
}
Or you can rename the variables to a different name of the element, because your problem is that the variables that contain the generated numbers are the same name as the id of the html element. If rename will work according to your first code.

Javascript Can Push() and Pop() and Image Replacement Work within an Array

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

window.setTimeout(getTest, 750);

Checking function for sliding puzzle javascript

I created a sliding puzzle with different formats like: 3x3, 3x4, 4x3 and 4x4. When you run my code you can see on the right side a selection box where you can choose the 4 formats. The slidingpuzzle is almost done. But I need a function which checks after every move if the puzzle is solved and if that is the case it should give out a line like "Congrantulations you solved it!" or "You won!". Any idea how to make that work?
In the javascript code you can see the first function loadFunc() is to replace every piece with the blank one and the functions after that are to select a format and change the format into it. The function Shiftpuzzlepieces makes it so that you can move each piece into the blank space. Function shuffle randomizes every pieces position. If you have any more question or understanding issues just feel free to ask in the comments. Many thanks in advance.
Since I don't have enough reputation I will post a link to the images here: http://imgur.com/a/2nMlt . These images are just placeholders right now.
Here is the jsfiddle:
http://jsfiddle.net/Cuttingtheaces/vkyxgwo6/19/

As always, there is a "hacky", easy way to do this, and then there is more elegant but one that requires significant changes to your code.
Hacky way
To accomplish this as fast and dirty as possible, I would go with parsing id-s of pieces to check if they are in correct order, because they have this handy pattern "position" + it's expected index or "blank":
function isFinished() {
var puzzleEl = document.getElementById('slidingpuzzleContainer').children[0];
// convert a live list of child elements into regular array
var pieces = [].slice.call(puzzleEl.children);
return pieces
.map(function (piece) {
return piece.id.substr(8); // strip "position" prefix
})
.every(function (id, index, arr) {
if (arr.length - 1 == index) {
// last peace, check if it's blank
return id == "blank";
}
// check that every piece has an index that matches its expected position
return index == parseInt(id);
});
}
Now we need to check it somewhere, and naturally the best place would be after each move, so shiftPuzzlepieces() should be updated to call isFinished() function, and show the finishing message if it returns true:
function shiftPuzzlepieces(el) {
// ...
if (isFinished()) {
alert("You won!");
}
}
And voilà: live version.
How would I implement this game
For me, the proper way of implementing this would be to track current positions of pieces in some data structure and check it in similar way, but without traversing DOM or checking node's id-s. Also, it would allow to implement something like React.js application: onclick handler would mutate current game's state and then just render it into the DOM.
Here how I would implement the game:
/**
* Provides an initial state of the game
* with default size 4x4
*/
function initialState() {
return {
x: 4,
y: 4,
started: false,
finished: false
};
}
/**
* Inits a game
*/
function initGame() {
var gameContainer = document.querySelector("#slidingpuzzleContainer");
var gameState = initialState();
initFormatControl(gameContainer, gameState);
initGameControls(gameContainer, gameState);
// kick-off rendering
render(gameContainer, gameState);

Here we have the initGame() function that starts everything. When called it will create an initial state of the game (we have default size and state properties to care about there), add listeners on the controls and call render() function with the current state.
initGameControls() sets up a listener for clicks on the field that will 1) call movePiece() which will try to move clicked piece on the blank spot if the former is somewhere around, 2) check if after move game is finished with checkFinish(), 3) call render() with updated state.
Now render() is a pretty simple function: it just gets the state and updates the DOM on the page accordingly.
Utility function initFormatControl() handles clicks and updates on the form for field size selection, and when the 'Play!' button is pressed will generate initial order of the pieces on the field and call render() with new state.
The main benefit of this approach is that almost all functions are decoupled from one another: you can tweak logic for finding blank space around target piece, to allow, for example, to swap pieces with adjacent ids, and even then functions for rendering, initialization and click handling will stay the same.

$(document).on('click','.puzzlepiece', function(){
var count = 0;
var imgarray = [];
var test =[0,1,2,3,4,5,6,7,8,'blank']
$('#slidingpuzzleContainer img').each(function(i){
var imgalt = $(this).attr('alt');
imgarray[i] = imgalt;
count++;
});
var is_same = (imgarray.length == test.length) && imgarray.every(function(element, index) {
return element === array2[index];
});
console.log(is_same); ///it will true if two array is same
});
try this... this is for only 3*3.. you pass the parameter and makethe array value as dynamically..
