I am trying to click on the button class "btn ActionBar__button", but there are 2 of them and it always clicks on the button that contains the title "Don't Click".
How can I click on the button with the same class, but has a different title?
I am trying to use this code:
var elems = document.getElementsByClassName('btn ActionBar__button'); elems[0].click();
Here is the HTML:
<div class="ActionBar">
<button class="btn ActionBar__button" type="button" title="Don't Click">Don't Click</button>
<button class="btn ActionBar__button" type="button" title="Click on this button">Click on this button</button></div>
You can use .querySelector
let elem = document.querySelector('[title="Click on this button"]');
console.log(elem)
elem.click();
<div class="ActionBar">
<button class="btn ActionBar__button" type="button" title="Don't Click">Don't Click</button>
<button class="btn ActionBar__button" type="button" title="Click on this button">Click on this button</button></div>

I am making a Simon game, but I need to get the "id" (attribute) value. but whenever I click on the different color it still gives me the first attr value which is in this case is green. how many times do I click on the red, blue, or yellow button but it still gives me a green value (the first one). help, please!
//Below code HTML
<div class="container">
<button class="btn green" id="green"></button>
<button class="btn red" id="red"></button><br />
<button class="btn yellow" id="yellow"></button>
<button class="btn blue" id="blue"></button>
</div>
//Below code Jquery
$(".btn").click(function () {
var userChosenColor =$(".btn").attr("id");
console.log(userChosenColor);
});
Reference to the button clicked.
You do not necessarily need jQuery for this.
$(".btn").click(function () {
var userChosenColor = $(this).attr("id");
console.log('jQuery: '+ userChosenColor);
});
/* non jQuery */
const btns = document.querySelectorAll('.btn');
btns.forEach(btn=> {
btn.addEventListener('click', () => {
console.log('JS only: '+btn.id)
});
});

<div class="container">
<button class="btn green" id="green">1</button>

<button class="btn yellow" id="yellow">3</button>

I have a page with many articles. Each article has a delete button. How can I identify the button clicked for the article?
Currently I have this:
<button type="button" id="delete-article" class="btn btn-small btn-danger">Delete</button>
$('#delete-article').on('click', function(e) {
console.log('Test delete article');
});
This logs 'Test delete article' according to the number of articles on the page.
You can attach the event on button and use this object to refer the currently clicked button:
$('button').on('click', function(e) {
console.log(this.id);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button type="button" id="delete-article" class="btn btn-small btn-danger">Delete</button>
<button type="button" id="delete-article-2" class="btn btn-small btn-danger">Delete</button>
You can use your event variable to get the target of the event (that is, the element responsible) and from there get its id, like this:
let btnId = event.target.id;
However, for that to work properly you should assign unique ids to your buttons. If you want to provide other data (or you don't want to use id) you can append custom attributes, like data-value or similar, and use it like this:
let myValue = event.target.getAttribute('data-value');
You need to establish relation between article and corresponding button, one way to implement is by using HTML5 data attribute.
assign data-articleId to article id in button element and when you click the button you can access which button was clicked by using Jquery .data() function.
<button type="button" data-articleId='123' class="btn btn-small btn-danger delete-article">Delete</button>
$('.delete-article').on('click', function(e) {
$(this).data('articleId'); //will return 123;
console.log('Test delete article');
});
If all the buttons have this markup
<button type="button" id="delete-article" class="btn btn-small btn-danger">Delete</button>
Then the DOM sees them as just one button, you should find a way to attach unique ids to your buttons
You can get an object of clicked button then you can get any details from that object like an index or whatever you want.
$('#delete-article').click(function(){
console.log($(this));
console.log($(this).index());
});
You can directly achieve it by using the JavaScript.
document.addEventListener('click',(e)=>{
console.log(e.target.id)
})
<button type="button" id="delete-article1" class="btn btn-small btn-danger">Delete1</button>
<button type="button" id="delete-article2" class="btn btn-small btn-danger">Delete2</button>
<button type="button" id="delete-article3" class="btn btn-small btn-danger">Delete3</button>
<button type="button" id="delete-article4" class="btn btn-small btn-danger">Delete4</button>
<button type="button" id="delete-article5" class="btn btn-small btn-danger">Delete5</button>
<button type="button" id="delete-article6" class="btn btn-small btn-danger">Delete6</button>
<button type="button" id="delete-article7" class="btn btn-small btn-danger">Delete7</button>
I'm trying to make a calculator with html and JavaScript. After clicking on the button i'm trying to insert the number into my div. When i do so the default '0' disappears and it does not insert anything at all.
function copy(event) {
var newValue = event.target.value;
document.querySelector("#display").innerHTML = newValue;
}
var textfield = document.querySelector("#btn_7");
textfield.addEventListener("click", copy);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="frame">
<div id="display">0</div>
<button id="btn_7">7</button>
<button id="btn_8">8</button>
<button id="btn_9">9</button>
<button id="btn_div">/</button>
<button id="btn_4">4</button>
<button id="btn_5">5</button>
<button id="btn_6">6</button>
<button id="btn_prod">*</button>
<button id="btn_1">1</button>
<button id="btn_2">2</button>
<button id="btn_3">3</button>
<button id="btn_min">-</button>
<button id="btn_clear">C</button>
<button id="btn_0">0</button>
<button id="btn_eq">=</button>
<button id="btn_plus">+</button>
</div>
If I add a string to newValue variable it shows in my div. So it means like when I press on the button it doesnt give anything to the div. Is there a way to solve this?
And about var textfield = document.querySelector("#btn_7");
For now I have to make this for each button and thats will take a lot of rows is there a better way to do so?
Buttons don't have a default attribute value, so in this case use the attribute textContent.
I recommend you to use a hidden input to store the values or you can also use data-attributes.

You can use the function document.querySelectorAll(selector) and loop over it to bind the specific event.
function copy(event) {
var newValue = event.target.textContent;
document.querySelector("#display").innerHTML = newValue;
}
Array.prototype.forEach.call(document.querySelectorAll('button'), function(b) {
b.addEventListener("click", copy);
});

Here is to select value and replace html of display div. You need to do some extra stuff to achieve what is your desired output.
var display = $('#display');
$('.btn').click(function(e) {
var btn = e.target;
display.html(btn.id);
});
<script type="text/javascript" src="https://code.jquery.com/jquery-latest.min.js"></script>
<div id="frame">
<div id="display">0</div>
<button class="btn" id="btn_7">7</button>
<button class="btn" id="btn_8">8</button>
<button class="btn" id="btn_9">9</button>

<button class="btn" id="btn_prod">*</button>
<button class="btn" id="btn_1">1</button>
<button class="btn" id="btn_2">2</button>
<button class="btn" id="btn_3">3</button>

I have two buttons. One where i clone a div (button-add) and one where I remove a div (button-remove).
I want to disable the remove-button when I only have one div.
So for multiple divs, it looks like this:
<button type="button" class="btn btn-default btn-lg button-add">+1</button>
<button type="button" class="btn btn-default btn-lg button-remove">-1</button>
<div class="copybox"></div>
<div class="copybox"></div>
<div class="copybox"></div>
...and when there's only one div, I want it to look like this:
<button type="button" class="btn btn-default btn-lg button-remove" disabled>-1</button>
<div class="copybox"></div>
I use jQuery 1.11.3
Here you go. Hope this is what you need.
$('.btn').on('click',function(){
if($(this).text()=="+1")
{
$('.button-remove').prop('disabled',false);
$('div.copybox:first').clone().appendTo('body');
}
else
{
$('div.copybox:last').remove();
}
$('div.copybox').length==1?$(this).prop('disabled',true):$(this).prop('disabled',false)
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button type="button" class="btn btn-default btn-lg button-add">+1</button>
<button type="button" class="btn btn-default btn-lg button-remove">-1</button>
<div class="copybox">Copy</div>
<div class="copybox">Copy</div>
<div class="copybox">Copy</div>
Try using the $("div.copybox").length that DontVoteMeDown commented and then set an ID for the button remove. Once you do that, you can add a function to hide the button with this code.
document.getElementById(buttonID).style.display = 'none'
If later you decide to enable it again, then you can also add another if statement and then the code for that would be block instead of none
I have many buttons inside of webpage like this.
<div class="btn btn-sm btn-success mycustom_btn" onClick="javascript:clickinner();">more</div>
<div class="btn btn-sm btn-success mycustom_btn1" onClick="javascript:clickinner();">more</div>
<div class="btn btn-sm btn-success mycustom_btn2" onClick="javascript:clickinner();">more</div>
What i am trying to do is call function clickinner() on button onclick event. I tried to grab the button element by class name and change the target url.
The javascript code is as follows.
<script>
function clickinner(){
var mybtn=document.getElementsByClassName('btn');
mybtn.onClick="location.href='about-us.html'";
};
</script>
I don'twant to grab the element by Id so that i have to assign unique id each time. However whenever i click on any of buttons, the target link is not working.
Please help me.
The clicked button can be accessed by using this in the clickinner function, no need to get it by class name:
<div class="btn btn-sm btn-success mycustom_btn" onClick="javascript:clickinner(this);">more</div>
<div class="btn btn-sm btn-success mycustom_btn1" onClick="javascript:clickinner(this);">more</div>
<div class="btn btn-sm btn-success mycustom_btn2" onClick="javascript:clickinner(this);">more</div>
Furthermore, you can just directly redirect to the 'about-us' page, since you're already in the click event. So ...
<script>
function clickinner(target) { // Target refers to the clicked element
location.href='about-us.html';
};
</script>
... is enough.
If you need to go to different pages based on which class the button has, you can do something like:
function clickinner(target) {
if(target.classList.contains('mycustom_btn')) {
location.href = 'another-page.html';
} else {
location.href='about-us.html';
}
};
Add this as parameter to your function and change the location correctly
<div class="btn btn-sm btn-success mycustom_btn" onClick="javascript:clickinner(this);">more</div>
<div class="btn btn-sm btn-success mycustom_btn1" onClick="javascript:clickinner(this);">more</div>
<div class="btn btn-sm btn-success mycustom_btn2" onClick="javascript:clickinner(this);">more</div>
<script>
function clickinner(mybtn){
// Do your stuff here with the clicked button
location.href='about-us.html';
};
</script>

Working fiddle solution
HTML:
<div id="button">more</div>
<div class="btn btn-sm btn-success mycustom_btn">more</div>
<div class="btn btn-sm btn-success mycustom_btn">more</div>
<div class="btn btn-sm btn-success mycustom_btn">more</div>
JS:
var button = document.getElementById('button');
button.addEventListener('click', function(){
alert('only 1 button clicked');
window.location = 'about-us.html';
});
var buttons = document.querySelectorAll('.btn');
for(var i = 0; i < buttons.length; i++){
buttons[i].addEventListener('click', function(){
alert('each button clicked');
window.location = 'about-us.html';
});
}
Try this sample
<html>
<head>
<meta charset="UTF-8">
<title>First Page</title>
<script>
function clickinner() {
window.location.href = 'secondPage.html';
}
</script>
</head>
<body>
<div class="btn btn-sm btn-success mycustom_btn"
onClick="javascript:clickinner()">more</div>
<div class="btn btn-sm btn-success mycustom_btn1"
onClick="javascript:clickinner();">more</div>
<div class="btn btn-sm btn-success mycustom_btn2"
onClick="javascript:clickinner();">more</div>
</body>
