So I have a code so when I press a button a number goes up.
This is the html:
<button type="button" class="btn btn-default" onclick="javascript:btnClick()">+1</button>
This is the JavaScript:
function btnClick(){
timesClicked += 1;
document.getElementById('timesClicked').innerHTML = timesClicked;
return true
}
So I have a button that has +1 so when I press it the number goes up
I need a button that is disabled until that number gets to 5 for example then becomes clickable, is that possible? I'm still learning Javascript,
All help is appreciated.
If the button is disabled, a user cannot interact with it.
Try the following
window.onload=function() {
var count =0;
document.getElementById("btn").addEventListener("click", function() {
count++;
if(count === 5) {
this.innerHTML = "5 clicks reached!";
}
});
};
<button id="btn">Click</button>
You could try something like this:
document.getElementById("button").disabled = true;
timesClicked = 0;
function btnClick(){
timesClicked += 1;
document.getElementById('timesClicked').innerHTML = timesClicked;
if(timesClicked > 5){
document.getElementById("button").disabled = false;
}
}
<button type="button" id="button" class="btn btn-default" onclick="btnClick()">+1</button>
[].forEach.call(document.querySelectorAll("[data-click-vote]"), function(btn) {
btn.addEventListener("click", vote);
});
function vote() {
this.innerHTML = this.value=Math.min(++this.value, 5);
}
<button value="0" name="movie1" data-click-vote>+1</button> The Revenant<br>
<button value="0" name="movie2" data-click-vote>+1</button> Dracula<br>
<button value="0" name="movie3" data-click-vote>+1</button> The Usual Suspect<br>
Multiple buttons
Updates simultaneously value and innerHTML
You can submit the values using a <form>
You can achieve your requirement with JS and CSS as in the below solution.
You haven't tagged it with CSS but you might want to look at this as well.
Button is simply a disabled span. Clicks are registered and when the count requirement is satisfied, it springs to life and handles your clicks with the actual handler code. (You can add a handler instead of printing a click count)
window.onload = function() {
var count = 1;
document.getElementById("btn").addEventListener("click", function() {
count++;
this.innerHTML = "+" + count;
if (count >= 5) {
this.className = "btnenabled";
this.innerHTML = "Print Click Count!";
if(count > 5) {
document.getElementById("counter").innerHTML= "Click Count is " + count;
}
}
});
};
.btnenabled {
width:200px;
background-color: blue;
padding: 3px;
border-radius: 3px;
color: white;
font-weight: bold;
display:block;
text-align:center;
}
.btnenabled:hover {
background-color:purple;
}
.btndisabled {
width:200px;
padding: 3px;
border-radius: 3px;
display:block;
text-align:center;
background-color: grey;
color: #F0F0F0;
font-weight: 100;
}
<span id="btn" class="btndisabled"> +1 </span>
<span id="counter"></span>

Hello everybody I have this code that I have made alone.
function appearafter() {
document.getElementById("buttonappear").style.display = "block";
document.getElementById("button").style.display = "block";
document.getElementById("hinzufuegen").style.display = "none";
function myFunction() {
var itm = document.getElementById("myList2").lastChild;
var cln = itm.cloneNode(true);
document.getElementById("myList1").appendChild(cln);
}
function allFunction() {
myFunction();
appearafter();
}
#button {
display: none;
}
#buttonappear {
display: none;
}
#test {
width: 300px;
height: 300px;
background-color: red;
}
<!DOCTYPE html>
<html>
<body>
<button id="hinzufuegen" onclick="allFunction()">ADD</button>
<div id="myList1">
<button id="button" onclick="">DELETE</button>
<div id="myList2">
<div id="test">
</div>
</div>
</div>
<button onclick="allFunction()" id="buttonappear">ADD</button>
</body>
</html>
What I want to make is that the red square whenever you are clicking on the ADD button it will be a clone and when you click on the DELETED button that the clone is deleted. Can somebody help me, please?
In addition to missing } as was mentioned in the comments, there was a not-so-obvious problem with finding the <div> to clone. The lastChild was actually a text node containing the \n (newline), after the <div>. It's better to search for <div> by tag:
var itm = document
.getElementById('myList2')
.getElementsByTagName('div')[0];
Since there's only one <div> we can use the zero index to find this first and only one.
And for delete function you can use a similar approach and get the last <div> and remove it.
function appearafter() {
document.getElementById("buttonappear").style.display = "block";
document.getElementById("button").style.display = "block";
document.getElementById("hinzufuegen").style.display = "none";
}
function myFunction() {
var itm = document.getElementById("myList2").getElementsByTagName("div")[0];
var cln = itm.cloneNode(true);
document.getElementById("myList1").appendChild(cln);
}
function deleteFunction() {
var list1 = document.getElementById("myList1");
var divs = Array.from(list1.getElementsByTagName("div"));
// If the number of divs is 3, it means we're removing the last
// cloned div, hide the delete button.
if (divs.length === 3) {
document.getElementById("button").style.display = "none";
}
var lastDivToDelete = divs[divs.length - 1];
list1.removeChild(lastDivToDelete);
}
function allFunction() {
myFunction();
appearafter();
}
#button {

I need a button which can change the background color if you click it 2x.
How can I do this?, I only know how to do it with 1 click.
My code is actually this:
<button onClick="document.body.style.backgroundColor ='#000';"> color </button>
Use onDblClick instead:
<button onDblClick="document.body.style.backgroundColor ='#000';"> color </button>
You can store the number of clicks in a variable and add a click event listener to the button that increments the counter and checks whether it is 2, and if so, sets the background color of the body.
var clicks = 0;
btn.addEventListener('click', function(){
if(++clicks == 2){
document.body.style.backgroundColor ='#000';
}
})
<button id="btn"> color </button>
Similar to the response of #Spectric, store the number of clicks in a variable and add a click event listener to the button.
I don't know logic is what is desired.
You could add another button with an idea equal to the one placed, but in reverse: subtracting.
const btnEle = document.querySelector(".btn");
const resEle = document.querySelector(".result");
const legendEle = document.querySelector("#legend");
let clickCount = 0;
btnEle.addEventListener("click", () => {
clickCount++;
resEle.innerHTML = "The button has been clicked " + clickCount + " times ";
if (clickCount > 1) {
document.body.style.backgroundColor ='#000';
legendEle.style.color = '#1E5128';
}
});
body {
font-family: "Segoe UI", Tahoma, Geneva, Verdana, sans-serif;
}
.result {
font-size: 18px;
font-weight: 500;
color: blueviolet;
}
<div class="result"></div>
<br />
<button class="btn">CLICK HERE</button>
<h3 id="legend">Click on the above button to check if the button is clicked</h3>
<input type="button" id="btn" onclick="eventB()">
function eventB() {
var click = 0;
btn.addEventListner('click', function() {
if(++click == 2){
window.document.body.style.background = '##836fff';
}
})
I'm using a button tag to create the button. I want to disable the button when I click on it. But I'm not able to do it. I hope someone here can help me...
You need to change the .disabled property of the button.
var btn = document.querySelector("#submit-btn");
btn.disabled = true;
Live example:
var btn = document.querySelector("#submit-btn");
btn.addEventListener('click', function() {
submit();
});
function submit() {
btn.disabled = true;
}
#submit-btn {
width: 100%;
height: 30px;
border: solid black .5px;
}
#submit-btn:disabled {
background-color: gray;
}
<input type="submit" id="submit-btn" value="Submit">

I am trying to highlight the single line of text in <textarea> with time delay. And I am wondering if I can choose a different color? The thing I wanted is when I click on the first <button>, the first line is highlighted into blue, click on the second <button>, 1 second later, the second line is highlighted into blue, lastly click on the third <button>, 2 second later, the third line is highlighted into yellow. I noticed I have a bug that I clicked on the button 3 times then the highlight doesn't work, but it is okay for me, I just want to know how to make the time delay and highlight with a different color. Thank you very much.
$( document ).ready(function() {
var str = 'line 1\nline 2\nline 3\n';
var textNumChar = str.length;
$('#str').val(str);
startPosition = 0;
$(".lines").click(function() {
var tarea = document.getElementById('str');
for(i=startPosition;i<textNumChar;i++)
{
if(str[i]=='\n') {
endposition = i;
break;
}
}
tarea.selectionStart = startPosition;
tarea.selectionEnd = endposition;
startPosition = endposition+1;
});
});

You can use setTimeout() to set the delay in highlighting the text based on button id.
And ::selection css selector to style the portion of an element that is selected.
$( document ).ready(function() {
var str = 'line 1\nline 2\nline 3\n';
var textNumChar = str.length;
$('#str').val(str);
startPosition = 0;
$(".lines").click(function(e) {
var tarea = document.getElementById('str');
for(i=startPosition;i<textNumChar;i++)
{
if(str[i]=='\n') {
endposition = i;
break;
}
}
var time = 0;
var tar_id = e.target.id;
var colors;
if(tar_id == 'line1' ) { colors = 'red'; }
else if(tar_id == 'line2' ) { time = 1000; colors = 'blue'; }
else if(tar_id == 'line3' ) { time = 2000; colors = 'green'; }
setTimeout(function(){
tarea.selectionStart = startPosition;
tarea.selectionEnd = endposition;
startPosition = endposition+1;
$('body').addClass(colors);
}, time);
});
});

In my options page I generate some rows with an input number and a button, related to entries at chrome storage.
The problem is that the event listener i'm creating for the buttons doesn't work at all.
options.html
<html>
<head>
<title>Select the movie's Id</title>
<style>
body: { padding: 10px; }
.style-1 input[type="number"] {
padding: 10px;
border: solid 1px #dcdcdc;
transition: box-shadow 0.3s, border 0.3s;
width: 5em;
}
.style-1 input[type="number"]:focus,
.style-1 input[type="number"].focus {
border: solid 1px #707070;
box-shadow: 0 0 5px 1px #969696;
}
</style>
</head>
<body>
<legend style="border-bottom: solid 1px">Insert</legend>
<input type="number" name="id" id="id" value="">
<button id="save">Insert</button>

<legend style="border-bottom: solid 1px">Manage</legend>

<input type="number" name="VAL">
<button name="DEL" id="" >Delete</button>
<br><br>
</div>
<script src="options.js"></script>
</body>
options.js
document.getElementById('save').addEventListener('click', save_options);
chrome.storage.sync.get('movieId', function(result){
for (var i=0; i<result.movieId.length; i++){
createRow(result.movieId[i]);
}
});
function save_options() {
var id = document.getElementById('id').value;
chrome.storage.sync.get('movieId', function(result){
var ids = result.movieId;
ids.push(id);
chrome.storage.sync.set({
'movieId': ids
}, function() {
});
location.reload();
});
}
function createRow(pos){
var newRows= document.getElementById('ghost').cloneNode(true);
newRows.id= '';
newRows.style.display= 'block';
var newRow= newRows.childNodes;
for (var i= 0; i< newRow.length; i++){
var newName= newRow[i].name;
if (newName){
newRow[i].name = newName+pos;
newRow[i].id = pos;
newRow[i].value = pos;
}
}
var insertHere= document.getElementById('ghost');
insertHere.parentNode.insertBefore(newRows,insertHere);
document.getElementById(pos).addEventListener('click', delet());
}
function loop(arrayIds){
console.log('loop');
for (var i=0; i<arrayIds.length; i++){
createRow(i);
}
}
function delet(){
console.log("this.id");
//chrome.storage.sync.remove(id);
}
With this, when I click any of the Delete buttons nothing happens.
I've tried all the combinations I can think for document.getElementById(pos).addEventListener('click', delet()); but none of them work.
document.getElementById(pos).addEventListener('click', delet());
is supposed to be
document.getElementById(pos).addEventListener('click', delet);
In your snippet you are calling delet thus result of that function is added as event listener that is undefined. If you want to bind delet as event handler, pass it to addEventListener without calling it.
EDIT
As I saw your code, you are giving same id to both input and button and when you call document.getElementById it returns input instead of button so, event is binded to input instead of button.
To fix that replace your createRow with this
function createRow(pos) {
var newRow = document.getElementById('ghost').cloneNode(true);
newRow.id= '';
newRow.style.display= 'block';
var value = newRow.querySelector("[name=VAL]");
var button = newRow.querySelector("[name=DEL]");
value.id = "VAL" + pos;
value.value = pos;
button.id = "DEL" + pos;
var insertHere= document.getElementById('ghost');
insertHere.parentNode.insertBefore(newRow, insertHere);
button.addEventListener('click', delet);
}
