click on specific sibling after matching text found

I have many of the below 'k-top' div elements, with the same inner div structure, except different unique text in two places, in 'k-in' and in my checkbox id.
<div class="k-top">
<span class="k-icon k-i-expand"></span><-------------- trigger click on this if below text is found
<span class="k-checkbox-wrapper" role="presentation">
<input type="checkbox" tabindex="-1" id="unique TEXT99" class="k-checkbox">
<span class="k-checkbox-label checkbox-span"></span>
</span>
<span class="k-in">unique TEXT99</span></div><- if this text is found in k-in trigger click on elem above
I want to iterate through all my span.k-ins until I find the innerText to match contains of 'unique' for instance, then once unique is found, I want to .click(); on it's sibling element '.k-i-expand' as seen in the mark-up above. I do not want to trigger a .click(); on all .k-i-expand just the specific one that has same parent as where my 'unique text' is found.
Thus far I have tried .closest, I have also tried sibling.parent.. both return null or undefined.. Note, I am not using jQuery.
The below works successfully to click all .k-i-expand - but I need to .click() only the one where k-in innerText contains 'unique'. Ideally I'd use starts with, or contains, but I'd specify the whole word if needed i.e. unique TEXT99
let exp = document.querySelectorAll('.k-i-expand');
let i;
for (i = 0; i < exp.length; ++i) {
exp[i].click();
};
More previous attempts can be seen here: how to run a .click on elems parent sibling selector?

I created a recursive function which checks all it's Siblings until it finds one with the specified innerHTML. If it does not find one, it does nothing:
function checkSibling(node) {
if (node.innerHTML == "unique TEXT99") {
return true;
} else if (node.nextSibling) {
return checkSibling(node.nextSibling);
} else {
return false;
}
}
async function clickOnNode() {
let exp = document.querySelectorAll(".k-i-expand");
for await (const node of exp) {
const hasText = await checkSibling(node);
if (hasText) {
console.log("Result: ", hasText);
node.click();
}
}
}
clickOnNode();
I also created a codepen with the code for you to play around. I guess the innerHTML check could be improved via a Regex.

Have you tried iterating over the .k-top elements and looking into each one to find your .k-in?
const expandItemsContaining = (text) => {
// Let's get all the .k-top divs
const kTops = document.querySelectorAll('.k-top');
// And peek into each and every one of them
kTops.forEach(kTop => {
// First we check whether there is a .k-in containing your text
const kIn = kTop.querySelector('.k-in');
const shouldClick = kIn && kIn.innerText && kIn.innerText.indexOf(text) !== -1;
// And if there is one we find the .k-i-expand and click it
if (shouldClick) {
const kExpand = kTop.querySelector('.k-i-expand');
if (kExpand) {
kExpand.click();
}
}
})
}

Class not working jQuery

So I more than one dynamicly generated elements with the same class name that I am trying to check input for in jQuery. Instead of it letting me click on both, it is just letting me click the first element generated.
Ex: I click on item_1 and it returns the item_1 id, but when I click on item_2 it doesn't return anyting.
HTML
<div id="item_1" class="resp"></div>
<div id="item_2" class="resp"></div>
JS - Jquery
$(".resp").on("click",() =>{
var id = $(".resp").attr("id");
console.log('attempting toggle' + id);
});

Firstly, you have to use normal function instead of arrow function (to avoid missing the context). Secondly - use this keyword to refer to the actually clicked element.
$(".resp").on("click", function() {
console.log('attempting toggle ' + this.id);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="item_1" class="resp">A</div>
<div id="item_2" class="resp">B</div>

This is because .attr('id') returns the value of the id attribute of the first matched element in the set.
Instead, use an old school function for the handler so the this value is equal to the clicked div, then get its id:
$(".resp").on("click", function() {
var id = $(this).attr('id');
console.log('attempting toggle ' + id);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="item_1" class="resp">First</div>
<div id="item_2" class="resp">Second</div>

What you're doing here is referencing the classname to obtain the id. This gathers the id of the first classname, which isn't what you desire. What you need to do is use the this keyword to correctly obtain the id.
After removing the arrow function and changing the internal code a bit, it should look like this:
$(".resp").on("click", function() {
var id = this.id;
console.log('attempting toggle: ' + id);
});
Also make sure you've correctly installed JQuery. Pick up your JQuery embed code from here.
Also remember to include your JQuery code before your JavaScript code.

one function to fire on same class elements click

I'm trying to make controls for category list with sub-category and sub-sub-category lists.
Here's HTML:
<ul class="selectbox-ul">
<li>
<div>Category</div>
<ul class="selectbox-ul-child">
<li>
<div>Subcategory</div>
<ul class="selectbox-ul-child">
<li>
<div>Sub-subcategory</div>
</li>
</ul>
<span id="trigger">icon</span>
</li>
</ul>
<span id="trigger">icon</span>
</li>
....
</ul>
So my shot was to add class for ul.selectbox-ul-child :
var trigger = document.getElementById("trigger");
function subCatStatus() {
if(this.parentElement.children[1].className != "... expanded") {
this.parentElement.children[1].className += " expanded"
} else {
this.parentElement.children[1].className == "..."
};
};
trigger.addEventListener("click", subCatStatus);
And it works only for first span#trigger(that shows subcategories), next one (for sub-subcategories) does nothing (I've also tried to use .getElementsByClassName it didn't work for any of triggers) . So i'd like to get some explanation why doesn't this one work. And some advice how to make it work.

As others have already mentioned, you can't stack multiple elements with the same ID since document.getElementById() is not supposed to return more than one value.
You may try instead to assign the "trigger" class to each of those spans instead of IDs and then try the following code
var triggers = document.getElementsByClassName("trigger");
function subCatStatus() {
if(this.parentElement.children[1].className != "... expanded") {
this.parentElement.children[1].className += " expanded"
} else {
this.parentElement.children[1].className == "..."
};
};
for(var i = 0; i < triggers.length; i++) {
triggers[i].addEventListener("click", subCatStatus);
}

javascript getElementById returns only single element so it will only work with your first found element with the ID.
getElementsByClassName returns an array of found elements with the same class, so when adding listener to the event on element you would require to loop through this array and add individually to it.

Get All Parents Info Up Until Specified Parent

I have this html codes example:
<html>
<body>
<div>
<div id="stophere">
<h4 class="parentclass">
<span class="target">Clicked</span>
</h4>
</div>
</div>
</body>
</html>
From the html codes example above, I want to get all parents' tag name of class target (when receiving click event) down from div with id stophere.
I tried this code:
$(ev.target).parents()
.map(function() {
return this.tagName;
})
.get()
.join( ", " );
But it includes all parents' tag names above stophere. While the result I want is only 1 div and 1 h4.
What is the correct way to get all parents of target down from stophere?

You can use the parentsUntil method for that
$(ev.target).parentsUntil($('#stophere').parent())
Note that it's non-inclusive, so we pass the parent of #stophere to include that element as well
FIDDLE

I don't claim that this is a good solution, but can be used if adeneo's solution is failed in your situation like in my case.
This code is checking whether the traversing limit is containing that limit line itself or not, by using find() method:
jQuery('html').on("click", function (ev) {
var elemparentid = jQuery(ev.target).closest("[id]").attr("id");
var thisparents = jQuery(ev.target).parents()
.map(function () {
// check if traversing limit is a children of current element or not, by using find() method
if (jQuery(this).find("#" + elemparentid).length < 1) {
return this.tagName;
}
}).get()
.join(", ");
alert(thisparents);
});
FIDDLE

How to check if an element with id exists or not in jQuery?

I'm generating a div dynamically and I've to check whether a dynamically generated div exists or not ? How can I do that?
Currently I'm using the following which does not detects the div generated dynamically. It only detects if there is already an element with the id contained in the HTML template.
$(function() {
var $mydiv = $("#liveGraph_id");
if ($mydiv.length){
alert("HHH");
}
});
How can I detect the dynamically generated div?

If mutation observes aren't an option due to their browser compatibility, you'll have to involve the code that's actually inserting the <div> into the document.
One options is to use a custom event as a pub/sub.
$(document).on('document_change', function () {
if (document.getElementById('liveGraph_id')) {
// do what you need here
}
});
// without a snippet to go on, assuming `.load()` for an example
$('#container').load('/path/to/content', function () {
$(this).trigger('document_change');
});

If it is added dinamically, you have to test again. Let's say, a click event
$("#element").click(function()
{
if($("#liveGraph_id").length)
alert("HHH");
});

How you inserting your dynamic generated div?
It works if you do it in following way:
var div = document.createElement('div');
div.id = 'liveGraph_id';
div.innerHTML = "i'm dynamic";
document.getElementsByTagName('body')[0].appendChild(div);
if ($(div).length > 0) {
alert('exists'); //will give alert
}
if ($('#liveGraph_id').length > 0) {
alert('exists'); //will give alert
}
if ($('#liveGraph_id_extra').length > 0) {
alert('exists'); //wont give alert because it doesn't exist.
}
jsfiddle.

Just for interest, you can also use a live collection for this (they are provided as part of the DOM). You can setup a collection of all divs in the page (this can be done in the head even before the body is loaded):
var allDivs = document.getElementsByTagName('div');
Any div with an id is available as a named property of the collection, so you can do:
if (allDivs.someId) {
// div with someId exists
}
If the ID isn't a valid identifier, or it's held in a variable, use square bracket notation. Some play code:
<button onclick="
alert(!!allDivs.newDiv);
">Check for div</button>
<button onclick="
var div = document.createElement('div');
div.id = 'newDiv';
document.body.appendChild(div);
">Add div</button>
Click the Check for div button and you'll get false. Add the div by clicking the Add div button and check again—you'll get true.

is very simple as that
if(document.getElementById("idname")){
//div exists
}
or
if(!document.getElementById("idname")){
// don't exists
}
