I'm having here a <select> that looks like this:
<select id="stdin-select" class="io-byte-box" size="10">
<option>0x5232</option>
<option>0xFD13</option>
<option>0x13E7</option>
<option>0x1234</option>
<option>0xFFFF</option>
</select>
and I am trying to access the values by its index like this:
var stdinValue = $('.stdin-select.dropdown option').eq(0).text();
and this
var stdinValue = $('.stdin-select option').eq(0).text();
like described here but it's not working.
What am I doing wrong here?
Change class (.) to id ('#')
var stdinValue = $('#stdin-select option').eq(0).text();
In your example there is not element with class stdin-select, instead there is element with if stdin-select

I know the starting word of the string present in the h2 element. How to find the ID of that element using contains?
The string present inside h2 is 'What Repairs Can Fix A P0500 Trouble Code?'. The sub string 'P0500' varies so it is not known. Is there a way to find the id using only the known words of the string.
const word = 'P0500';
let id = $(`h2:contains(${word})`).attr('id');
console.log(id);
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
<h2 id="heading2">What Repairs Can Fix A P0500 Trouble Code?</h2>
It's working fine for me. I added a working snippet for the reference.
let id = $('h2:contains("test")').attr('id');
console.log(id);
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<h2 id="1">div1</h2>
<h2 id="2">This is a test, nested in div1</h2>
<h2 id="3">Nested in div1<h2>

I am trying to get the element itself through making a function in the div itself I want when someone clicks on the current Element the Element should be deleted by fading in pure JavaScript I have searched on the internet but not getting the answer there are many similar questions on Stack Overflow but none of them giving me the combined answer(Like getting current element through Js in (inline function)).
So anyone can help me
<div style="width: 100px;height: 100px;background:red;" onclick="(function(ele){
console.log('helo')
console.log(ele.currentTarget)})();">
Thanks in advance
This should do it:
I added an id to your div which can be accessed through the getElementById.
<div id='hello' style="width: 100px;height: 100px;background:red;" onclick="
(
function() {
document.getElementById('hello').style.opacity = 0;
document.getElementById('hello').style.transition = '0.5s';
}
)();">

So I have an ol with several li like this:
<ol id="monday">
<li id="zero1"><input type="hidden" name="mo[]" value="cero1"><button type="button"">15</button></li>
</ol>
<button type="button" onclick="update()"> Update</button>
And I can change the content of the ol, but when I try to change the name attribute with jquery it remains the same, Is there something wrong with my function?
function update(){
$("#monday input").each(function (){
$("this").attr("name", "mo[]");
});
}
this is a keyword and it should not be a String here
function update(){
$("#monday input").each(function (){
$(this).attr("name", "mo[]");
});
}

I want to get the id from a class selector without clicking.
var type_selected = '' ;
$('.type_selected').attr();
type_selected = (this.id);
Use this. This will return an array of all elements with that class;
var type_selected = [];
$('.type_selected').each(function(){
type_selected.push($(this).attr("id"));
});
console.log(type_selected);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p class="type_selected" id="id1">This is a test<p>
<p class="type_selected" id="id2">This is a test 2<p>
<p class="type_selected" id="id3">This is a test<p>

I'm trying to do a basic math function and change the contents of a <p></p> element but when I click the button, it does nothing.
I know it's something trivial but I thought this would work.
What am I missing?
HTML
<button onclick="doMath()">Click</button>
<p id="output"></p>
JavaScript
function doMath() {
var total = 6/2(2+1);
document.getElementById("output").innerHTML = total;
}
function doMath() {
var total = (6/2*(2+1));
document.getElementById("output").innerHTML = total;
}
<button onclick="doMath()">Click</button>
<p id="output"></p>
