I'm building a todo list in vanilla JavaScript as a part of the exercise. I'm trying to get the 'edit' option to function properly. When I click the 'edit' button, the corresponding text input should be enabled, and auto-selected, then the user should be able to press 'enter' to submit changes.
The problem is that I cannot make Edit functional. Two of the other buttons are working well.
I know that there is similar question allready, and I have tried what was in that question, and still cannot get it done. Please help guys.

if (elementClicked === 'edit') {
var input = document.getElementById(position).childNodes[0];
input.disabled = false;
input.className = "activeTextInput";
input.focus();
input.select();
input.addEventListener('keyup', function(event) {
if(event.keyCode === 13) {
var textInput = input.value;
input.disabled = true;
input.classList.remove("activeTextInput");
todoButtons.changeTodo(position, textInput);
};
});
};
});
}
};
// Starting event listeners when the app starts
todoView.setUpEventListeners();
So, I looked at the code. The first problem is the condition:
if (elementClicked === 'edit') {
It should be:
if (elementClicked === 'editButton') {
The second problem was:
if (elementClicked === 'edit') {
var input = document.getElementById(position).childNodes[0]; //this line
input.disabled = false;
input.className = "activeTextInput";
It should be var input = document.getElementById(position).querySelector('input'); to get the correct element.
https://jsfiddle.net/nh9j6yw3/1/
Reason for "undefined" :
on line todoLi.textContent = todoButtons.todoText + ' ';
todoButtons.todoText is undefined.

I am creating a simple picture matching game and I will love to make sure when the picture is clicked once, the event listener is removed, this will help me stop the user from clicking on the same image twice to get a win, and then when the user clicks on another element the listener should be added back, I tried doing this with an if statement but the listener is only removed and never added back, I decided to reload the page which somehow makes it look like a solution but I need a better solution that can help me not to reload the page but add the listener back so that the element can be clicked again after the last else if statement run.

you have to define function outside of onclick because you will need this function reference to remove or add it to eventlistener later
see a example below
function onload(){
var main = document.querySelector(".main"),
btns = main.querySelectorAll(".buttons input"),
box = main.querySelector(".box")
btns[0].addEventListener("click",function(){
box.addEventListener("click",functionForEvent)
})
btns[1].addEventListener("click",function(){
box.removeEventListener("click",functionForEvent)
})
function functionForEvent(e){
console.log("clicked")
}
}
onload()
<div class="main">
<div class="box" style="height:120px;width:120px;border:1px solid black;">Click Me</div>
<div class="buttons">
<input type="button" value="Add Event">
<input type="button" value="Remove Event">
</div>
</div>
Here is an example, that shows how to remove the click event from the item clicked and add it to the other items.
It colors the items that can be clicked green, and the item that can't be clicked red.
To keep the example short, it doesn't check, if the elements it operates on, are well defined.
function myonload() {
let elems = document.querySelectorAll('.mydiv');
for(let i = 0; i < elems.length; ++i) {
let elem = elems[i];
elem.addEventListener('click', mydiv_clicked);
}
}
function mydiv_clicked(e) {
let elems = document.querySelectorAll('.mydiv');
for(let i = 0; i < elems.length; ++i) {
let elem = elems[i];
if(elem == e.target) {
elem.removeEventListener('click', mydiv_clicked);
elem.classList.add('mycolor_clicked');
elem.classList.remove('mycolor');
// Do additional logic here
} else {
elem.addEventListener('click', mydiv_clicked);
elem.classList.remove('mycolor_clicked');
elem.classList.add('mycolor');
// Do additional logic here
}
}
}
.mydiv {
height:30px;
width: 200px;
border:1px solid black;
margin-bottom:2px;
}
.mycolor {
background-color:#00ff00;
}
.mycolor_clicked {
background-color:#ff0000;
}
<body onload="myonload()">
<div class="mydiv mycolor">First area</div>
<div class="mydiv mycolor">Second area</div>
<div class="mydiv mycolor">Third area</div>
</body>
The example shown here does not need to check if an event handler already exists, as adding the same event handler twice, replaces the existing one.
You could also add a custom attribute to your elements and toggle it, instead of adding and removing event listeners as shown here and name your attribute data-something, for example data-can-be-clicked.
I am coding in Joomla in which I have self synchronized three audio tracks i.e when one of them starts on the web page the other stop and below is the JS code for the same;
<script type="text/javascript">
function _(id) {
return document.getElementById(id);
}
//function Download(url) {
//document.getElementById('my_iframe').src = url;
//};
function audioApp() {
var audio = new Audio();
var audio_folder = "/images/audios/how-to-meditate/relaxation/";
var audio_ext = ".mp3";
var audio_index = 1;
var is_playing = false;
var playingtrack;
var trackbox = _("trackbox");
var tracks = {
"track1": ["Relaxation in the Forest", "relaxation-in-the-forest"],
"track2": ["Relaxation of the Muscles", "relaxation-of-the-muscles"],
"track3": ["Relaxation with the Breath", "relaxation-with-the-breath"]
};
for (var track in tracks) {
var tb = document.createElement("div");
var pb = document.createElement("button");
//var dn = document.createElement("button");
var tn = document.createElement("div");
tb.className = "trackbar";
pb.className = "playbutton";
//dn.className = "download";
tn.className = "trackname";
tn.innerHTML = tracks[track][0];
pb.id = tracks[track][1];
tb.appendChild(pb);
pb.addEventListener("click", switchTrack);
tb.appendChild(tn);
trackbox.appendChild(tb);
audio_index++;
}
audio.addEventListener("ended", function() {
_(playingtrack).style.background = "url(images/icons/play.JPG)";
playingtrack = "";
is_playing = false;
});
function switchTrack(event) {
if (is_playing) {
if (playingtrack != event.target.id) {
is_playing = true;
_(playingtrack).style.background = "url(images/icons/play.JPG)";
event.target.style.background = "url(images/icons/pause.JPG)";
audio.src = audio_folder + event.target.id + audio_ext;
audio.play();
} else {
audio.pause();
is_playing = false;
event.target.style.background = "url(images/icons/play.JPG)";
}
} else {
is_playing = true;
event.target.style.background = "url(images/icons/pause.JPG)";
if (playingtrack != event.target.id) {
audio.src = audio_folder + event.target.id + audio_ext;
}
audio.play();
}
playingtrack = event.target.id;
}
}
window.addEventListener("load", audioApp);
</script>
Below is the Styling;
<style scoped="scoped" type="text/css">
.trackbar {
background: #FFF;
height: 50px;
font-family: "Arial";
}
.trackbar:nth-child(even) {
background: #FFF;
}
.playbutton {
opacity: .8;
display: block;
float: left;
width: 40px;
height: 40px;
margin: 0px 50px 0px 50px;
background: url(images/icons/play.JPG) no-repeat;
border: none;
cursor: pointer;
outline: none;
}
.playbutton:hover {
opacity: 1;
}
.trackname {
float: left;
color: #000;
margin: 12px 400px 0px 14px;
font-size: 20px;
}
And the html code is;
<div id="trackbox"> </div>
Having achieved this I want to place a download icon besides every mp3 which allows me to download the track, I have the link to download the file and it is placed in the media (Content) of Joomla and also I want a icon to be placed which will trigger the download onClick.
Is there a JS script code available with which I can implement the same.
This is what solved the issue;
<input alt="Submit" src="images/icons/download.jpg" type="image" onclick="document.getElementById('anything').click()" />
The following code converts text into equal paragraphs, based on the users input character amount.
Is it possible for the input box to calculate the amount of words for each paragraph instead of being based on the character amount?
JSFiddle
If an updated fiddle could please be provided, would be much appreciated, as I am still new to coding.
Thank You!

JS
$(function() {
$("#divide").click(function() {
var text = $("#input").val();
var wpp = 10 // words per paragraph
var words = text.split(" ");
var paras = [];
for (i = 0; i < words.length; i += wpp) {
paras.push(words.slice(i, i + wpp).join(" "));
}
$.each(paras, function(i, para) {
$("#paras").append("<p>" + para + "</p>");
});
});
})
JSFiddle
The following fiddle converts texts into paragraphs and the problem is the JQuery function attribute chunkSize = 100; currently defines the amount of characters for each divided paragraph to contain.
Is it possible for the user to be able to change this dynamically through the use of an <input> and <button> where the user would be able to type their desired characters for each dynamic paragraph and apply it?
Fiddle
If a new fiddle could please be provided, it would be very much appreciated, as I am still new to coding.
Thank You!

Give an id for your input.
<input id="custom" placeholder="Custom Characters per box" style="width:200px;">
Add below code into initialDistribute function.
custom = parseInt(document.getElementById("custom").value); //Get value of the input.
chunkSize = (custom>0)?custom:100; //If Custom value is more than `0`, take that as `chunkSize` value else `100`
See Fiddle
You can use input type="number" element, button element; set chunkSize to input type="number" valueAsNumber property at click of button
html
<label>chunkSize:<input class="chunkSize" type="number" /></label>
<button class="chunkSize">
Set chunkSize
</button>
javascript
$("button.chunkSize").click(function(e) {
var _chunkSize = $("input.chunkSize")[0].valueAsNumber;
chunkSize = _chunkSize;
})

So, what I am going to do with the input tag is to insert as many as email address inside it.
<input type="text" name="email-tags"/>
To make it more user-friendly, I want to highlight each-email which is typed inside it with blue color, it looks similar like a tag in SO question which also has x button to delete the tag.
Can anybody please help me how to do this with javascript?
Thanks in advance.
This block of code actually does what you need. It's pretty advanced. I hope it suits your needs. document.getElementById("test").value contains the email addresses in an array in this example.
function setInputEmailToExtendedInput()
{
var inputs = document.querySelectorAll("input[data-type='email']");
Array.prototype.slice.call(inputs).forEach(function(element){
var node = new emailInput();

{
node.container.id = element.id;
}
if (element.className)
{
node.container.className = element.className;
}
element.parentElement.replaceChild(node.container, element);
});
}

Object.defineProperty(this, "value", {
value: [],
enumerable: false
});
Object.defineProperty(this, "placeholder", {
get: function() {
this.container.input.placeholder;

set: function(value) {
this.container.input.placeholder = value;
},
enumerable: false
});
}
function emailEvaluateOnChange(obj, e) {

obj.evaluateTag(e.target.value);
}

} else if (e.keyCode == 8) //backspace
{
if (e.target.value.length == 0 && obj.value.length > 0) //length of the input is zero.
{
//delete tag.
obj.deleteTag();
return true;
}
} else if (e.keyCode == 27) //escape

//hide the input helper and blur the input.
e.target.blur();
e.preventDefault();
return false;
