when I click on title ( Title Goes Here) text. I am getting null for nextElementSibling instead of a element...
Edit
you can nest any elements inside an <a> except the following :
<a>
<button>
follow link
<a> and<button> both are invalid..
but I am getting null for a tag.. not for button tag.... I am looking for more clarity and valid source...
if I console log console.log(document.links) .. it's give three HTMLCollection collection...
End Edit
Below Example Code
console.log(document.links)
document.querySelectorAll(".viewAbstractToggleTitle").forEach(function(item) {
item.addEventListener("click", function(e) {
if (e.target.parentElement.classList.contains('viewAbstractToggleTitle')) {
console.log(e.target.parentElement.nextElementSibling.nextElementSibling)
console.log(e.target.parentElement.nextElementSibling.nextElementSibling.nextElementSibling);
console.log(e.target.parentElement.nextElementSibling.nextElementSibling.nextElementSibling.nextElementSibling);
}
})
})

Your HTML is invalid. You have disallowed things like nested hyperlinks. This means the HTML parser, which is designed to be forgiving in spite of errors, has to come up with a new interpretation of your element tree. Here's what Firefox at least translates it to:
<li style="border-bottom: 1px solid #d6d6d6;margin-bottom:10px;">
<a href="javascript:void(0)">
<span class="viewAbstractToggleTitle" style="display:inline-block;line-height:1.6 !important">
<span style="font-weight: 600;font-size:16px;">
Title Goes Here
</span>
<span> ( 1-10 page )</span>
</span>
<br>
<div class="authors">
<span><i class="fa fa-user" aria-hidden="true"></i>

</span>
<span><i class="fa fa-user" aria-hidden="true"></i>

</span>
</div>
<span>
span tag
</span>
</a>
<a class="inlineBlock" href="" download="">
<i class="fa fa-download" aria-hidden="true"></i> Download PDF</a>
<a class="inlineBlock viewAbstractToggle" href="javascript:void(0)"> <i class="fa fa-eye" aria-hidden="true"></i> View Article</a>
<div class="showTabe sTab">
<div class="tabBox">
<div class="tab">
<label class="label" for="tab1_">Abstract</label>
<label class="label" for="tab2_">Graphical of Author </label>
</div>
<div class="box">
<div class="content"><input id="tab1_"> Description
</div>
<div class="content"><input id="tab2_">
<p>image</p>
</div>
</div>
</div>
</div>
<br>
</li>
You can get this information for yourself by copying the HTML from your browser's DOM inspector.
As you can see, the other <a/> elements are not siblings of .viewAbstractToggleTitle. This is because the DOM parser had to insert a closing of your first <a/> element since you cannot nest them.

This is my case, i want to select the " .ant-upload-list-item-card-actions > a" when the class "ant-upload-list-item-name ant-upload-list-item-name-icon-count-1" contains fileDoc.doc
I made this
candidateUploadFileButton = '#filesUpload';
candidateUploadRemoveButton = '.ant-upload-list-item-card-actions > a';
cy.get(this.candidateUploadFileButton, {force: true}).contains(fileName);
cy.get(this.candidateUploadRemoveButton).click();
It works for a single input only for a single div class, if there two classes like in the previously example , it doesn't work beacuse it says there are multiple values
I added this picture, maybe it will help what i want to do, i want to press Remove button for the file named "fileDoc.doc"

Refer here:
As per your markup, you can use this:
cy.contains(fileName).next().find('> a').click()
I have a very simple module to develop. On click of an image I need to open up a div element that I have created.I have attached my HTML and javascript file.When I am loading the page the div wont be coming because I have given style="display:none
myfunction() {
document.getElementById('Chatbot').style.visibility = "visible";
}
<body>
<a href="#Chatbot" id="chat" onclick="myfunction()">
<img src="sticky.png" style="width:50px;height:50px">
</a>
<div id="Chatbot" style="display:none">
<div id="header">

<div class="icons">

<i class="fa fa-refresh" aria-hidden="true"></i>

<div><textarea rows="3" cols="20">Press enter to send your message</textarea>

</body>
document.getElementById('Chatbot').style.display = "block";
function myfunction() {
document.getElementById('Chatbot').style.display = "block";
}
<body>
<a href="#Chatbot" id="chat" onclick="myfunction()">

Avoid using inline scripts and also avoid capitalising the first letter of your ID or class name.
Just add an event listener to your #chat anchor link that loads a function which sets the css display property of your div to block on click like this:
/* JavaScript */
var chat = document.getElementById("chat");
var div = document.getElementById('chatbot');
function showDiv(){
div.style.display = "block";
}
chat.addEventListener("click", showDiv);
/* CSS */
a {text-decoration: none; padding: 5px; background-color: green; color: white;}
#chatbot {display: none;}
<!-- HTML -->
<a type="button" href="#Chatbot" id="chat">Open Div</a>
<hr>
<div id="chatbot">
<div id="header">
Legal Genie
<div class="icons">
<i class="fa fa-question-circle" aria-hidden="true"></i>
<i class="fa fa-refresh" aria-hidden="true"></i>
<i class="fa fa-times" aria-hidden="true"></i>
</div>
</div>
<div><textarea rows="3" cols="20">Press enter to send your message</textarea>
</div>
It can be a simple way
<script>
$( document ).ready(function() {
$('#chat').click( function(){
if ( $('#Chatbot').hasClass('active') ) {
$('#Chatbot').removeClass('active');
} else {
$('#Chatbot').addClass('active');
}
});
});
</script>
Add lil css
<style>
.active {
display:block!important;
}
</style>
Your HTML
<body>
<div id="chat">
Some Image
</div>
<div id="Chatbot" style="display:none">
<div id="header">

I have an expand/collapse using jQuery which works fine on the first level:
This is my razor file:
#model IntDashMakeRecAssgnmntsPoRespMngrVM
<div style="border:1px dotted blue;padding:5px">
<div>
<i class="fa fa-user-circle"></i> <i class="fa fa-user-circle"></i>
</div>
<i id="collapseMakeRecAssignments" title="Show Make Recommendation Assignments" class="fa fa-plus-circle pull-left" style="display:block;cursor:pointer"></i>
<i id="expandMakeRecAssignments" title="Hide Make Recommendation Assignments" class="fa fa-minus-circle pull-left" style="display:none;cursor:pointer"></i>
<span style="margin-left:2px">Make Recommendation Assignment for POs and Responsible Manager (#Model.Audits.Count())</span>
<div id="MakeRecommendationAssignmentsDiv" style="display:none;margin-left:40px;padding:5px;border:0px dotted black">
#foreach (var audit in Model.Audits)
{
<div>
<i id="expandRecommendations#(audit.AuditID)" title="Show Recommendations Needing Assignment" class="fa fa-plus-circle pull-left" style="display:block;cursor:pointer"></i>
<i id="collapseRecommendations#(audit.AuditID)" title="Hide Recommendations Needing Assignment" class="fa fa-minus-circle pull-left" style="display:none;cursor:pointer"></i>
<span style="margin-left:2px"><b>#audit.AuditAcnCd</b></span>
<div id="RecommendationDiv#(audit.AuditID)" style="margin-left:40px;padding:5px;border:0px dotted black">
#foreach(var finding in audit.Findings)
{
foreach(var rec in finding.Recommendations)
{
<div style="display:none;">
<a asp-controller="InternalRecommendations" asp-action="Details" asp-route-id="#rec.RecommendationId"
title="Make assignment for #audit.AuditAcnCd">
<b>#audit.AuditAcnCd/#finding.FindingCd/#rec.RecCd</b>
</a>
</div>
}
}
</div>
</div>
}
</div>
</div>
This is my jQuery:
$("#collapseMakeRecAssignments, #expandMakeRecAssignments").click(function () {
$("#MakeRecommendationAssignmentsDiv").toggle();
$("#collapseMakeRecAssignments, #expandMakeRecAssignments").toggle();
});
This is very simple to make the first level expand and collapse.
But now I need the nested 3 newly shown divs in the expanded div to each expand.
This is the jQuery I am writing to try and expand the inner divs.
// Wire up dynamic toggle
var expandNodes = $('i[id^="expandRecommendations"]');
expandNodes.each(function (index) {
console.log(this.id);
console.log(parseInt(this.id.replace(/[^0-9\.]/g, ''), 10));
expandNodeId = parseInt(this.id.replace(/[^0-9\.]/g, ''), 10);
expandNodeDivId = "RecommendationDiv" + expandNodeId;
console.log("#" + expandNodeDivId)
$("#" + expandNodeDivId).click(function (e) {
$("#" + expandNodeDivId).toggle();
});
});
In this line:
var expandNodes = $('i[id^="expandRecommendations"]');
I am getting all of my i tags that have a font awesome class (+ sign in a circle) acting as an expand button.
Now I roll through each of the "+ in a circle" buttons in the expandNodes collection and get the unique id I assigned to each of them with razor building on the server side (
<div id="RecommendationDiv#(audit.AuditID)" style="display:none;margin-left:40px;padding:5px;border:0px dotted black">
and try to add a click event to each one to toggle itself which should show itself and the anchor divs nested inside of itself:
But it just won't won't expand.
Here are the console.logs showing I'm getting the right id's to call the element to expand:
These console.log lines show I am getting the write information to try to wire this up but I just can't get them to expand:
expandRecommendations279938 // the div I clicked on
279938 // able to parse the audit id from the id of the element I clicked on.
#RecommendationDiv279938 // concatenated the Text part of the element I want to expand with the id for the second part of the element to expands id.
Anyone see the problem here? Any help would be greatly appreciated.
UPDATE 1
Here is the HTML source produced from the server side.

I figured it out.
Here is the revised JavaScript:
// Wire up dynamic toggle
var expandNodes = $('i[id^="expandRecommendations"]');
expandNodes.each(function (index) {
expandNodeId = parseInt(this.id.replace(/[^0-9\.]/g, ''), 10);
create_expand_toggle(expandNodeId);
});
function create_expand_toggle(nodeId) {
$("#" + "expandRecommendations" + nodeId).click(function (e) {
console.log("Clicking");
$("#" + "RecommendationDiv" + nodeId).toggle();
});
}
I was referencing the same div I wanted to expand in the button click. I needed to make a second reference to the i tag with the font awesome + class acting as the button to hook up the click event.
Once tip. I tried to make a var for the two node id references and use them so it would be more readable. But then the click event for all three plus signs on that level show the same div. The last div. So I have to concatenate the ids in the create_expand_toggle function.
Writing an angular app in bulma, copied the template directly from the template site for testing and I get this error. I have checked and checked and everything is closed properly, yet somehow I keep getting an unclosed nav error. Oddly enough when I delete the closing nav tag, the site compiles correctly, but is broken. I have no idea what to do.

in my case I was forgetting a detail in the tag
<button class="btn btn-primary" (click) "handleClickMe()

I forgot to put the "=" in (click)="handleClickMe()
Usually if you see an "Unexpected closing tag <something>" the problem isn't actually with that <something> but rather with an adjacent element that hasn't been properly closed. Paste stuff here: https://validator.w3.org or any similar HTML validator service, or use a better editor/IDE that offers syntax highlighting to help you find these errors.
You are missing a closing </div> tag.
You close navbar-brand, navbar-menu and navbar-end but you do not close <div class='container'>
As this missing </div> tag ought to be directly before </nav>, you get the error telling you, in fact, exactly where you ought to look. "I found a </nav> I wasn't expecting to see!" ... Ok, so go look at wherever you have a </nav> and figure out what element nearby is missing or has typos, etc.
Adding for future reference, for Angular
I've also seen this where you have invalid html like this
<p>
<div>

Change the p to a div and it'll work
Basically I have a carousel slider which I am using to display dates so that a user can scroll across (img below)
Everything works as it should but my only struggle now is to disable that left button once a user has scrolled so far.. example below
<div class="dates-bar">
<a class="centralprev prev"> <i class="fa fa-angle-left"> </i>
</a>
<a data-date="24/07/2016" class="centraldateconed" style="margin-left: 140px;"> <span class="date">24/07</span> <span class="month">July</span> <span class="tick"> </span>
</a>
<a data-date="24/07/2016" class="datecon"> <span class="date">31/07</span> <span class="month">July</span> <span class="tick"> </span>
</a>
<a data-date="2/08/2016" class="datecon"> <span class="date">02/08</span> <span class="month">August</span> <span class="tick"> </span>
</a>
<a data-date="03/08/2016" class="datecon"> <span class="date">03/08</span> <span class="month">August</span> <span class="tick"> </span>
</a>
<a data-date="07/08/2016" class="datecon"> <span class="date">07/08</span> <span class="month">August</span> <span class="tick"> </span>
</a>
<a class="centralnext next"> <i class="fa fa-angle-right"> </i>
</a>
</div>
Thanks in advance for your assistance.
This might work:
when you click on .centralprev if the number of visible .datecon elements inside .dates-bar is equal to 1 then .centralprev will be hidden, else it will be shown and so will .centralnext:
$(".centralprev").click(function(){
if($(".dates-bar>.datecon:visible").length===1){
$(".centralprev").hide();
}
else{
$(".centralprev").show();
$(".centralnext").show();
}
})
And vice versa for the other button:
$(".centralnext").click(function(){
if($(".dates-bar>.datecon:visible").length===1){
$(".centralnext").hide()
}
else{
$(".centralnext").show();
$(".centralprev").show();
}
})
