How to do that witn Pure JavaScript?
I need clear code or just guidelines.
From what I gathered from your question this what I believe you need. Hopefully it will get you going in the right direction.
var textAreaID = "user-input";
//turn the text area content into an array
var content = document.getElementById(textAreaID).innerHTML.split("\n");
//create array to hold new Content
var newContent = [];
//loop through and add line numbers
for (var i = 0; i < content.length; i++) { //begin for loop
//append the line numbers and the new value to the newContent array
newContent.push((i + 1) + content[i] + "\n");
} //end for loop
//update the content of textArea with line numbers
document.getElementById(textAreaID).innerHTML = newContent.join("");
<textarea id="user-input" name="user-input" rows="15" cols="40">
Hello is it working?
I think so.
</textarea>

I'm trying to create a function that inserts a randomly chosen word from an existing array into a div. I figured this thing out and now I need to insert an image at the end of every word generated after pressing a button. Any ideas? thanks!
var words = function() {
var wordsArray = new Array('Sun', 'Door', 'Table', 'Moon', 'Sky', 'Chair');
var i;
for (i = 0; i < wordsArray.length; i++) {
var newWords = wordsArray[Math.floor(Math.random() * wordsArray.length)];
document.getElementById('wordhere').innerText = newWords;
}
};
<button class="generate-button" onclick="words();">generate!</button>
<div class="title h4" id="wordhere"></div>
Inside the loop you can replace the statement with:
document.getElementById("wordhere").innerHTML = `${newWords}<img src = "path">`
Basically you can write any node inside that template literal

my question is probably simple for most but its troubling me and ive been googling for sometime now.
I dont want allow copy or paste content and emoji characters in input fields.
var checkTf = function() {
let charcode_max = 255;
let tf = document.getElementById("tf");
for (let i = tf.value.length - 1; i >= 0; i--) {
if (tf.value[i].charCodeAt(0) > charcode_max) {
tf.value = tf.value.substr(0, i) + tf.value.substr(i + 1);
}
}
}
<html>
<head></head>
<body>
<textarea id="tf" oninput="checkTf()"></textarea>
</body>
</html>
You may increase charcode_max.

I've been figuring out how to have a typing effect that is word per word instead of letter per letter. So far, all links I've searched are offering letter per letter typewriter effect.
https://macarthur.me/typeit/
https://github.com/mattboldt/typed.js/
Is this possible to achieve? Or have you done something similar?
This is pretty easy.
Just register an interval, split your text, reverse the array and pop the last item. The one you append to the text-container then. Done.
JS
var myText = "Some text you want to be typed automagically..";
var myWords = myText.split(" ").reverse();
var ntrvl = setInterval(function() {
addNextWord();
}, 150);
function addNextWord() {
var nextWord = myWords.pop();
if(nextWord !== undefined) {
var textNow = $(".write-here").text() + " " + nextWord;
$(".write-here").text(textNow);
}
}
What do you think of this?
JSfiddle
create an array with whichever words you want to print one at a time.
const sentence = 'this sentence will be displayed one word at a time';
var arrayOfWords = sentence.split(' ');
for (var i = sentence.length - 1; i >= 0; i--) {
setTimeout(function(){
console.log(sentence[i]); // or display another way
}, 400) // set this to your desired interval
}

Can someone please tell me how to compare elements in array with every other element. I mean in array arr = [a,b,c,d];, I would like to compare a with b,c,d , b with a,c,d, etc. And to do that dynamically, no mather of the size of the array.
Try this:
var a=["a","b","c","d"];
for(var i=0;i<a.length;i++){
for(var j=0;j<a.length;j++){
if(i!=j && a[j]===a[i]){
//match, do whatever you want
}
}
}

that's part of my script:
var count = $(".sliderItem").length;
if (count < lp + 5)
{
alert("bp4");
var clips = count-l;
alert("bp5");
}
so the problem is: 'bp4' is visible but 'bp5' not.
when I change var clips = count-1; to var clips = 1; it works fine.
Somebody have some idea?
You don't have var clips = count-1; in your code, you have var clips = count-l;.
Change the letter l (lower case L) to 1 in your code.
