I am a beginner.
I want to display the HTML of previous element when the button is clicked.
I am able to display HTML content of button using outerHTML property. But when i use prev() function with the current object, it is showing error.
function show(currentObject) {
alert($(currentObject)[0].outerHTML);
}
above code gives the html content of the current button.
(Click) is shows as alert.
but
function show(currentObject) {
var prevObject = $(currentObject).prev();
alert($(prevObject)[0].outerHTML);
}
above code is giving me error!!
error: TypeError: $(...)[0] is undefined
Below is the html
<div class="row">
<div class="col-md-12"><a class="navbar-link" href="/somelink">linktext</a></div>
<div class="col-md-12"><p>click below button</p></div>
<div class="col-md-4"><button onclick="show(this)" class="btn btn-primary">Click</button></div>
</div>
Is there a way to do it right?
You can use .prev().html() to getting previous element html, check updated snippet below..
alert($('.currentItem').prev().html())
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="item1">Previous Element</div>
<div class="item1 currentItem">Current Element</div>
If you want to use pure Javascript use previousElementSibling
document.getElementById('foo').addEventListener('click', currentObject);
function currentObject() {
alert(this.parentNode.previousElementSibling.outerHTML);
}
body {
font: 13px Verdana;
}
<div class="row">
<div class="col-md-12"><a class="navbar-link" href="/somelink">linktext</a></div>
<div class="col-md-12">
<p>click below button</p>
</div>
<div class="col-md-4"><button class="btn btn-primary" id="foo">Click</button></div>
</div>

Im trying addClass to wizard-step when button clicked, but still no luck :/
<div class="mt-4">
<div class="wizard-steps">
<div class="wizard-step">
<div class="wizard-step-icon">
<i class="far fa-user"></i>
</div>
</div>
<form class="wizard-content mt-2" id="regForm">
<fieldset>
<div class="form-group row">
<div class="col-lg-4 col-md-6 text-right">
<button type="button" onclick="step0(this);" class="btn">Next</button>
</div>
</div>
</fieldset>
</form>
</div>
JavaScript:
<script>
function step0(element) {
$(element).prev('div').find('.wizard-step').addClass('wizard-step-active');
}
</script>
Can anyone please help me !
prev is used to retrieve a previous sibling element. The .wizard-step you want to target is a child of a sibling to a parent of the button being clicked. As such you need to use closest() instead.
Also note that onclick (and all the other onX attributes) are not good practice and should be avoided. As you're already using jQuery you can attach your event unobtrusively, like this:
jQuery($ => {
$('.btn').on('click', function() {
$(this).closest('.wizard-steps').find('.wizard-step').addClass('wizard-step-active');
});
});
.wizard-step-active { color: #C00; }
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="mt-4">
<div class="wizard-steps">
<div class="wizard-step">
<div class="wizard-step-icon">
<i class="far fa-user">User icon</i>
</div>
</div>
<form class="wizard-content mt-2" id="regForm">
<fieldset>
<div class="form-group row">
<div class="col-lg-4 col-md-6 text-right">
<button type="button" class="btn">Next</button>
</div>
</div>
</fieldset>
</form>
</div>
Alternatively, instead of calling find() from the shared parent, you could select the form and use prev():
$('.btn').on('click', function() {
$(this).closest('.wizard-content').prev('.wizard-step').addClass('wizard-step-active');
});
Either is fine, it just depends on how your HTML is structured as to which fits best for this use case.
You don't want the div immediately before the button, but the one containing the relevant item(s). So instead of $(element).prev('div') write $('.mt-4').
Your this parameter is referring your button, not your div.
You can do this without Jquery, just using your function like this:
function step0() {
const element = document.getElementsByClassName('wizard-step');
element.classList.add('wizard-step-active');
}
So, you don't need to pass this as a parameter to step0 function.
I have a div which I want to surround with an <a href>. I have the jQuery to add the <a href> after the div but I struggle to set it before and close it after the div.
This is the jQuery code I have:
$('.box_service').each(function() {
var link = $(this).html();
$(this).contents().wrap('');
});
It results in this HTML:
<div class="row">
<div class="box_service">
<a href="example.com">
<div class="inner-row"></div>
</a>
</div>
</div>
However my goal is this structure:
<div class="row">
<a href="example.com">
<div class="box_service">
<div class="inner-row"></div>
</div>
</a>
</div>
I can't enter the div before because there are more boxes in this row so I would add the <a href> to everything in there
The issue is due to your call to contents() which means you're wrapping the elements inside .box_service, not that element itself. Remove that method call.
Also note that each() is redundant, you can do what you require in a single line:
$('.box_service').wrap('');
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="row">
<div class="box_service">
Box service #1
<div class="inner-row">Inner row #1</div>
</div>
</div>
<div class="row">
<div class="box_service">
Box service #2
<div class="inner-row">Inner row #2</div>
</div>
</div>
.content will wrap the contents of your div, you want to wrap the div with <a> so call wrap on the div not on contents.
$('.box_service').each(function() {
var link = $(this).html();
$(this).wrap('');
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="row">
<div class="box_service">
<div class="inner-row"></div>
</div>
</div>
$('.box_service').each(function() {
var link = $(this).html();
$(this).wrap('');
});
You just need to remove contents() in between $(this).wrap() because contents() mean that you are wrapping the children of $(this).
Remove .contents() in order to wrap around each element with the class box-service:
$('.box_service').each(function() {
$(this).wrap('');
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="row">
<div class="box_service">
<a href="example.com">
<div class="inner-row"></div>
</a>
</div>
</div>
$('.box_service').wrap('');
I have a three button navigation panel, comprising of three divs and an anchor. On mouse over, myFunction() assigns a class to the three divs and anchor tag, for styling purposes.
<nav>
<div id="btn1" class="button" onMouseOver="myFunction();">
<div id="btn_bdr1">
<div id="btn_bdr2">
</div>
</div>
</div>
<div id="btn3" class="button" onMouseOver="myFunction();">
<div id="btn_bdr1">
<div id="btn_bdr2">
</div>
</div>
</div>
<div id="btn2" class="button" onMouseOver="myFunction();">
<div id="btn_bdr1">
<div id="btn_bdr2">
</div>
</div>
</div>
</nav>
What I need to do is find the ID of the div which called myFunction(), so I can make a change within the function to only the calling div, not all three.
Using JavaScript only, how can I go about doing this.
Thanks in advance.
There is two ways you can do is
1) Send an argument to the method with the div's name
Example
<div id="btn1" class="button" onMouseOver="myFunction('btn1')">
2) Send the element this
Example
<div id="btn1" class="button" onMouseOver="myFunction(this)">
In the javascript you can then do
myFunction(element) {
//element is now the element you clicked on
}
You can use the event object and look at the target (e.target). This is a reference to the element itself so to get the ID you would simply access the element's id property. (e.target.id)
document.querySelectorAll('.a').forEach(function(ele, ind) {
ele.addEventListener("mouseover", function(e) {
console.log(e.target, e.target.id);
})
});
.a {
height: 40px;
width: 40px;
border: solid black 3px;
margin-top: 5px;
}
<div class="a" id="one"></div>
<div class="a" id="two"></div>
<div class="a" id="three"></div>
You can call this.event.target from myFunction() to determine which element generated the event.
For example:
myFunction() {
console.log("I was called by: ", this.event.target);
}
I made this script, and despite one oddity, it works fine. It's hiding/showing the parent of div element with a class containing specific content. The problem when I press my <a> elements, that act as buttons, they "filter" the divs, but it leaves the first comment <a>? If I change the element do a <div> instead no problem, but with an <a> element it behaves weirdly? Is this just a bug or?
here is a JSFiddle: https://jsfiddle.net/g1puxhs7/2/
HTML:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js">
</script>
<a class='viewBtn'>Published<a>
<a class='viewBtn'>Completed<a>
<a class='viewBtn'>Created<a>
<div class="orders" id="orders">
<div class="row">
<div class="status">
Completed
</div>
<a>Comment</a>
</div>
<div class="row">
<div class="status">
Completed
</div>
<a>Comment</a>
</div>
<div class="row">
<div class="status">
Completed
</div>
<a>Comment</a>
</div>
</div>
<style>
.row {
width: 200px;
margin: 10px;
background: #ccc;
padding: 4px;
}
</style>
SCRIPT:
//--Filter by Status--//
$('.viewBtn').click(function() {
var txt = $(this).text();
$('.status:contains("' + txt + '")').parent().toggle();
$(this).toggleClass('down');
});
The problem is with your links:
<a class='viewBtn'>Published<a>
<a class='viewBtn'>Completed<a>
<a class='viewBtn'>Created<a>
You have 6 opening a tags, instead of 3 opening and 3 closing tags.
This is why the browser adds closing a tags in your script in a bunch of places, one of them in your first div—and then your whole DOM tree looks different than what you want.
Your markup needed to be cleaned up. Here is your markup cleaned up. Also, i find it best to add href for you anchor tags, and then you can comment them out with #, or you can add javascript:void(0). If you use the # approach, in your JS, you can add e.preventDefault();
HTML Cleaned:
<div>
<a class='viewBtn' href="#">Published</a>
<a class='viewBtn' href="#">Completed</a>
<a class='viewBtn' href="#">Created</a>
</div>
<div class="orders" id="orders">
<div class="row">
<div class="status">
Completed
</div>
<a class="stuff" onclick="Comment">Comment</a>
</div>
<div class="row">
<div class="status">
Completed
</div>
<a class="stuff">Comment</a>
</div>
<div class="row">
<div class="status">
Completed
</div>
<a class="stuff">Comment</a>
</div>
</div>
JS with preventDefault():
$('.viewBtn').click(function(e) {
e.preventDefault();
var txt = $(this).text();
$('.status:contains("' + txt + '")').parent().toggle();
$(this).toggleClass('down');
});
Ive made a fiddle of my problem here.
http://jsfiddle.net/E9cUS/1/
JavaScript:
$('.top').click(function () {
var thisPage = $(this).closest('.yesNoItem');
$('.yesNoTick').stop().animate({"opacity" : 1},400, function () {
thisPage.find('.no .top').stop().animate({"opacity" : 0},400, function () {
$(this).css("display", "none");
});
});
});
$('.yesNoNext').click(function () {
$(this).closest('.yesNoItem').stop().animate({"opacity" : 0},400, function () {
//This isnt working? Please advise?
$(this).next('.yesNoItem').stop().animate({"opacity" : 1},400);
});
});
HTML:
<div id="stage">
<div class="yesNoOuter">
<div class="yesNoItem" style="opacity:1;">
<div class="yesNoContainer yes">
<div class="top">
<div class="yesNoTick"></div>
</div>
<div class="bottom">
</div>
</div>
<div class="yesNoContainer no">
<div class="top">
<div class="yesNoTick"></div>
</div>
<div class="bottom">
<p>Text 1</p>
<div class="yesNoNext">More</span>
</div>
</div>
</div>
<div class="yesNoItem">
<div class="yesNoContainer yes">
<div class="top">
<div class="yesNoTick"></div>
</div>
<div class="bottom">
</div>
</div>
<div class="yesNoContainer no">
<div class="top">
<div class="yesNoTick"></div>
</div>
<div class="bottom">
<p>Text 2</p>
<div class="yesNoNext">More</span>
</div>
</div>
</div>
</div>
</div>
I've also put the line of code thats not working.
Bascially it is hiding the element that I want, but not fading the next one in...
Can any one advise based upon my code? Many thanks!
You had an error in your markup
<div class="yesNoNext">More</span>
if you correct that, next() works http://jsfiddle.net/E9cUS/2/
I think your HTML got messed up. The second .yesNoItem element is not a sibling but a child of the first .yesNoItem element (right click -> inspect element).
Probably because of <div class="yesNoNext">More</span> (opening div, closing span). The browser will attempt to correct this automatically and just ignore the closing span tag (at least this seems to be the case if you inspect the DOM).
If you correct your HTML it should work (at least it should select the right element).
If they are actually supposed to be nested, then .next() is the wrong method anyways.
