$(document).ready(function(){
$("button").click(function(){
$("#answer").toggle(1000);
});
});
this only works for the IDs "answer" and "button", the challenge for me its getting multiple pairs of these IDs (answer1 - button1, answer2 - button2, and so on) to work with this single function
You haven't included the relevant HTML so I can only guess/assume what it might look like in my demo/example.
For multiple elements it is best to use a class to group them.
$(document).ready(function() {
$(".answerTog").click(function() {
$(this).prev('.answer').toggle(1000);
});
});
.Question {
display: block;
margin-bottom: 5px;
}
.answer {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="Question">
<input type="text" placeholder="Question One" />
<span class="answer">Question One Answer.</span>
<button class="answerTog">See Answer</button>
</div>
<div class="Question">
<input type="text" placeholder="Question Two" />
<span class="answer">Question Two Answer.</span>
<button class="answerTog">See Answer</button>
</div>
<div class="Question">
<input type="text" placeholder="Question Three" />
<span class="answer">Question Three Answer.</span>
<button class="answerTog">See Answer</button>
</div>
If your button is before the answer then you can simply use
$(this).next('.answer').toggle(1000);
$(this) will target the specific element used to trigger the function call, in this instance the button being clicked.
.prev('.answer') will target the previous element with the class name of answer
.next('.answer') will target the next element with the class name of answer

If you have any questions about the source code above please leave a comment below and I will get back to you as soon as possible.
I hope this helps. Happy coding!
You are currently using an ID property to call that button ($('#')) You want to call them by classes.
IDs should be unique and only used in 1 DOM element.
Trying to use ID the script will only pick the 1st element it comes across; and the code will only work for that one button.
With classes you create an Object for all of your elements, with jQuery you just have to call the element by its class, and run the code normally - I note this because in JS you would have to add the index to the element call.
For example:
<canvas id="main"></canvas>
<div class="elem"></div>
<div class="elem"></div>
<div class="elem"></div>
<script>
var canvas = $('#main'), // return 1 element
elements = $('.elem'); // return 3 elements
</script>
So for anything that involves multiple elements you must call them by class or tag name.
In vanilla JS you would look at something like this:
<script>
var elem = document.querySelectorAll('.elem');
console.log(elem[0]);
</script>
So, your code would then just need to call those elements by class; and you can set custom classes for different purposes.
$(document).ready(function() {
var btns = $('.btn');
btns.click(function() {
btns.toggle(1000);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button class="btn">Button</button>
<button class="btn">Button</button>
<button class="btn">Button</button>
<button class="btn">Button</button>
<button class="btn">Button</button>

I need to display different output according to each different icon clicked without defining separate functions;
HTML:
<p onclick="expand()" id="i1">icon1</p>
<p onclick="expand()" id="i2">icon2</p>
<p onclick="expand()" id="i3">icon3</p>
<div id="blocki1"></div>
<div id="blocki2"></div>
<div id="blocki3"></div>
Can I do something like this with JS?
function expand() {
document.getElementById("block" + this.id).style.display = "block";
}
I've tried the method above which apparently didn't work, I need to a)store icon's id and b) combine the id with string. Don't sure if that's possible.
<p onclick="expand(this.id) id="i1">icon1</p>
<p onclick="expand(this.id) id="i2">icon2</p>
<p onclick="expand(this.id) id="i3">icon3</p>
<div id="blocki1"></div>
<div id="blocki2"></div>
<div id="blocki3"></div>
<script>
function expand(e) {
document.getElementById("block" + e).style.display = "block";
}}
</script>
First.. You have 4 typos. First 3 are that you don't have closing " after onclick="expand()
<p onclick="expand() id="i1">icon1</p>
<!-- There needs to be " after expand() -->
Last typo is you have extra closing } after expand function.
Now, since you're not using addEventListener API, the value of this will not be set on your expand function.
So you need to pass your current element as a parameter to the function.
<p onclick="expand(this)" id="i1">icon1</p>
<p onclick="expand(this)" id="i2">icon2</p>
<p onclick="expand(this)" id="i3">icon3</p>
<div id="blocki1">blocki1</div>
<div id="blocki2">blocki2</div>
<div id="blocki3">blocki3</div>
(Added some place holder text to divs to see if this works)
Lastly, access the current element in your function as a first parameter.
function expand(el) {
document.getElementById("block" + el.id).style.display = "block";
}
Pass parameters to the function
You need to pass some data (e.g. the reference to the object, its name, or whatever else you need) to the function you're calling.
For example, look at the sample code from https://www.w3schools.com/jsref/event_onclick.asp
<p onclick="myFunction(this, 'red')">Click me to change my text color.</p>
<script>
function myFunction(elmnt,clr) {
elmnt.style.color = clr;
}
</script>
I might approach it slightly differently by removing the inline JS, and using classes and data attributes. Here I have classes and data attributes on all the elements. I attach click event listeners to the "buttons" which call the handleClick function. This function checks the data id attribute of the button and grabs the corresponding slide, adding a "show" class to its class list.
const buttons = document.querySelectorAll('.button');
buttons.forEach(button => {
button.addEventListener('click', handleClick, false);
});
function handleClick(e) {
const id = e.target.dataset.id;
const slide = document.querySelector(`.slide[data-id="${id}"]`);
slide.classList.add('show');
}
.slide {
display: none;
}
.show {
display: block;
}
<p class="button" data-id="1">icon1</p>
<p class="button" data-id="2">icon2</p>
<p class="button" data-id="3">icon3</p>
<div class="slide" data-id="1">blocki1</div>
<div class="slide" data-id="2">blocki2</div>
<div class="slide" data-id="3">blocki3</div>
Your code should like this
<p onclick="expand(this) id="i1">icon1</p>
<p onclick="expand(this) id="i2">icon2</p>
<p onclick="expand(this) id="i3">icon3</p>
<div id="blocki1"></div>
<div id="blocki2"></div>
<div id="blocki3"></div>
<script>
function expand(elm) {
document.getElementById("block" + elm.id).style.display = "block";
}
</script>
If you are a beginner, I would suggest you to avoid practice of adding handlers in HTML, before it becomes your coding attitude.
Instead, add eventlisteners for them in js. Separation of concerns is really big theory.
And it's relativelyeasy to deal with this in event handlers
You can read more about it here
var ps = Array.from(document.querySelectorAll("p"));
for(var i=0; i< ps.length; i++){
ps[i].addEventListener(("click"), function(){
document.getElementById("block" + this.id).style.display = "block";
})
}
div{
display: none;
}
<p id="i1">icon1</p>
<p id="i2">icon2</p>
<p id="i3">icon3</p>
<div id="blocki1">This is 1</div>
<div id="blocki2">This is 2</div>
<div id="blocki3">This is 3</div>
I want to get a text from a textarea after clicking on button that is next to the textarea.
The problem is that I will have many textareas and every button must returns the text of the textarea that corresponds to it.
This is my code
function btnmodif(){
var mod = $(this).prev().val();
alert(mod);
};
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<div class="list-item-edit">
<textarea class="list_input">eggs</textarea>
<button class="btn btn-modify-item" onClick="btnmodif()">get text</button>
</div>
<div class="list-item-edit">
<textarea class="list_input">water</textarea>
<button class="btn btn-modify-item" onClick="btnmodif()">get text</button>
</div>
You have to pass object clicked to btnmodif function.
<button class="btn btn-modify-item" onClick="btnmodif(this)">get text</button>
JS
function btnmodif(button){
var mod = $(button).prev().val();
alert(mod);
};
Also, you should use .prev function.
Read more about .prev() function, here.
function btnmodif(button){
var mod = $(button).prev().val();
alert(mod);
};
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<div class="list-item-edit">
<textarea class="list_input">eggs</textarea>
<button class="btn btn-modify-item" onClick="btnmodif(this)">get text</button>
</div>
<div class="list-item-edit">
<textarea class="list_input">water</textarea>
<button class="btn btn-modify-item" onClick="btnmodif(this)">get text</button>
</div>
Firstly, you need to pass the clicked element as context to the function:
onClick="btnmodif(this)"
...
function btnmodif(button){
Second, if the HTML structure will remain the same (i.e. the textarea is always going to be the element immediately before the button), then you can use prev()
var mod = $(button).prev('textarea').val();
https://api.jquery.com/prev/
If that structure isn't guaranteed to be maintained, then .siblings() gives you a bit more flexibility, as it searches through all the elements at the same hierarchical level in the DOM to find what you want:
var mod = $(button).siblings('textarea').val();
https://api.jquery.com/siblings/
Here is what are you looking for.
Add this as parameter to your button.onclick
Thanks to jQuery:
Using $(element).parent(), you get your div element.
Using $(element).parent().find('.list_input'), you get your textarea element.
Using $(element).parent().find('.list_input').text() gives you the value of the textarea "related to" the clicked button.
function btnmodif(element){
var result = $(element).parent().find('.list_input').text();
alert(result);
};
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<div class="list-item-edit">
<textarea class="list_input">eggs</textarea>
<button class="btn btn-modify-item" onClick="btnmodif(this)">get text</button>
</div>
<div class="list-item-edit">
<textarea class="list_input">water</textarea>
<button class="btn btn-modify-item" onClick="btnmodif(this)">get text</button>
</div>
You're missing the this from the inline handler specification:
https://jsfiddle.net/3mvod6ux/
Use siblings with a selector to get the textarea's value that belong to the same block of the button clicked.
function btnmodif(button){
var mod = $(button).siblings("textarea").val();
alert(mod);
};
Another way to do this task .
Instead to use HTML event attribute this is better approach.
var btnModifyItem = $('.btn-modify-item');
btnModifyItem.click(function(){
var mod = $(this).prev().val();
alert(mod);
})
This way you can get the parent of button (and textarea) and then can get the text from child textarea:
$('button').on('click', function () {
console.log(($(this).parent().find("textarea").text()));
});
Let's say I have a template and I want to loop and create div's. I want to listen to clicks on the buttons contained in each of these divs:
<div class="repeatedDiv">
<button class="reply-button">
</div>
$('.reply-button').on('click',function(e)...)
I want to make the reply button function specific to the div that it was selected on. Would it be bad to have something like:
<div class="repeatedDiv">
<button class="reply-button" id="reply-{{this.id}}">
</div>
Don't make it more complicated than it really is
$(document).on('click', '.reply-button', function(e){
var divClicked = $(e.target).closest('.repeatedDiv');
// do something with clicked div
// var divClicked is the div elmt that contains the button that was clicked
// doing it this way you might not even need an id at all
console.log(divClicked.attr('id'));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="div1" class="repeatedDiv">
<button class="reply-button">div1</button>
</div>
<div id="div2" class="repeatedDiv">
<button class="reply-button">div2</button>
</div>
<div id="div3" class="repeatedDiv">
<button class="reply-button">div3</button>
</div>
And if you do need an id when creating a new div create it dynamically with e.g.
var newID = "id-" + Date.now();
console.log(newID);
I am using a jQuery function to add/remove a class to the clicked element, which works just fine. However when that element is clicked, I am trying to change the text of an HTML link and I cannot seem to get it working. The HTML link is located within the <span> element further down the page.
When <button id="people"> hasClass('user_view_active') the HTML link should display "People" when <button id="jobs"> hasClass('user_view_active') the HTML link should display "Jobs".
<script type="text/javascript">
$(document).ready(function() {
$('button').click(function(){
$('button').each(function(){
$(this).removeClass('user_view_active');
});
$(this).addClass('user_view_active');
});
if ($('#people').hasClass('user_view_active')){
$('.title').find("a").attr("href").text(text.replace('People'));
}else{
$('.title').find("a").attr("href").text(text.replace('Jobs'));
}
});
</script>
</head>
<body>
<div id="container">
<header>
<img src="images/header-name.png" width="200px" style="display: inline; margin-bottom: -10px;"/>
<button id="jobs" class="user_view">Jobs</button>
<button id="people" class="user_view_active user_view">People</button>
<div class="header_search_wrapper">
<form action="" method="POST">
<textarea class="header_search" name="app_search" placeholder="Search people, jobs, or companies" style="width: 430px;"></textarea>
<input type="submit" class="share_btn" value="Search">
</form>
</div>
</header>
<div id="main" role="main">
<!--! begin app content -->
<div class="right_sidebar">
<span class="right_title">Connection Suggestions</title>
</div>
<span class="title">Recent Updates >> People</span>
To replace the text within a link you can use the jQuery .text() function. This function can also get the text value and also set the text value - as is shown in the example below -
if ($('#people').hasClass('user_view_active')){
$('.title').find("a").text('People');
}else{
$('.title').find("a").text('Jobs');
}
This code would have to be wrapped in the callback function of the click event to work -
$(document).ready(function() {
$('button').click(function(){
$('button').removeClass('user_view_active');
$(this).addClass('user_view_active');
if ($('#people').hasClass('user_view_active')){
$('.title').find("a").text('People');
}else{
$('.title').find("a").text('Jobs');
}
});
});
Now each time the button is clicked, you can check for the existence of the user_view_active class on the #people element.
Okeydokey ?
Are you sure those are the right tags ?
<span class="right_title">Connection Suggestions</title>
Are you sure an <a> element inside a <button> element is a good idea?
<button id="jobs" class="user_view">Jobs</button>
role="main" is'nt a valid attribute, but will probably work anyway.
This just seems easier:
$(document).ready(function() {
$('button').on('click', function(){
$('button').removeClass('user_view_active');;
$(this).addClass('user_view_active');
$("a", ".title").text(this.id);
});
});
FIDDLE
Try this way:
$('#people').toggleClass('user_view_active').html($('#people').hasClass('user_view_active')?'People':'Jobs');
I have a bunch of smilies in a page, which on click has to be selected. I tried implementing a jquery based solution but am stuck at this stage, where multiple smilies are getting selected :
<div class="smiles_feed">
<input type="text" id="rating" value="" name="rating" class="displaynone" />
<div style="float:left;width:auto;text-align:Center;">
<button type="button" class="awesomesmile" class="unselected" value="Awesome" style="margin-bottom:0px;"></button>
<div class="smiletitle" style="font-size:9pt;color:white;">Yummy!</div>
</div>
<div style="float:left;width:auto;text-align:Center;">
<button type="button" class="goodsmile" class="unselected" value="Good" style="margin-bottom:0px;"></button>
<div class="smiletitle" style="font-size:9pt;color:white;">Good!</div>
</div>
<div style="float:left;width:auto;text-align:Center;">
<button type="button" class="okaysmile" class="unselected" value="Okay" style="margin-bottom:0px;"></button>
<div class="smiletitle" style="font-size:9pt;color:white;">Okay!</div>
</div>
<div style="float:left;width:auto;text-align:Center;">
<button type="button" class="yucksmile" class="unselected" value="Yuck" style="margin-bottom:0px;"></button>
<div class="smiletitle" style="font-size:9pt;color:white;">Yuck!</div>
</div>
</div>
<script type='text/javascript'>
$(function(){
// Smile Click Function
$('div.smiles_feed :button').click(function(){
$(this).removeClass('unselected').addClass('selected');
$(this).siblings().removeClass('selected').addClass('unselected');
$('#rating').val($(this).val());
//alert($('#rating').val());
});
});
</script>
What am I doing wrong? How do I change the javascript function to make it select only one smiley?
$(this) inside your click() function refers to the button that was clicked, not the div that was clicked. You need to add the selected class to $(this).parent().
The elements returned by siblings() are not the divs that represent other smileys, but rather are other elements of this smiley (in this case, div.smiletitle).
To get a list of the other smileys, you should be looking at $(this).parent().siblings().
If your button is what represents the smiley, then you should be traversing other smileys like this:
$(this).parent().siblings().children('button')
and making them each get deselected:
$(this).parent().siblings().children('button').each(function(){
$(this).removeClass('selected')
.addClass('deselected');
});
