I got a JavaScript file and a bootstrap form from the internet. On the page there are 2 inputs, when you fill them in it will add the numbers together and put the new number out.
When I tried it out it didn't do anything, in the console I got 2 errors. First one being that bootstraps JavaScript needed jQuery so I added that, and the second one says "Uncaught TypeError: Cannot read property 'addEventListener' of null", and I can't figure out why I get this error.
The form code is:

<h2 id="result"></h2>

The JavaScript code is:
var first = document.getElementById('first');
var second = document.getElementById('second');
var result = document.getElementById('result');
first.addEventListener("input", sum);
second.addEventListener("input", sum);
function sum() {
var one = parseFloat(first.value) || 0;
var two = parseFloat(second.value) || 0;
var add = one+two;
result.innerHTML = "Your Sum is : " + add;
}
So is there maybe anyone who can explain what I'm messing up here?
Add this before because your 'test.js' file is loaded before the DOM elements are loaded.
This is because you javascript file is loading first, than the Dom element is getting created. So when you js loads, it will look up for the elements with first and second which is not there at that time.
var first = document.getElementById('first');
var second = document.getElementById('second');
var result = document.getElementById('result');
first.addEventListener("input", sum);
second.addEventListener("input", sum);
function sum() {
var one = parseFloat(first.value) || 0;
var two = parseFloat(second.value) || 0;
var add = one+two;
result.innerHTML = "Your Sum is : " + add;
}

Read below:
Here's what happens when a browser loads a website with a tag on it:
Fetch the HTML page (e.g. index.html)
Begin parsing the HTML
The parser encounters a tag referencing an external script file.
The browser requests the script file. Meanwhile, the parser blocks and stops parsing the other HTML on your page.
After some time the script is downloaded and subsequently executed.
The parser continues parsing the rest of the HTML document.

I am trying to create a basic to do list app and the li in my code is not showing up in the console. I called li in the console to check and I get the error (Uncaught ReferenceError: li is not defined) but I'm confused because I thought I defined the li inside the function.

I'm assuming your javascript is actually in another file (app.js ?) and not just part of the html like it is written here.
I am using Google App Script to build a little web app. I'm just at the very start and the page charges well on both Chrome and Firefox but I can't get anything to happen on click of the log in button. I don't get any log to the logger, neither do I get the alert to pop up. Does anyone have any idea why?

I tried earlier to break down my code with the fuction InsertHTMLScript that I have written in the code, inserting <?!= InsertHTMLScript("HTML_CSS"); ?> into the HTML code and it didn't work either. I don't known if it's related but I just resolve not to use it to make things easier.
Thank you in advance
You misspelled getElementById
You have:
document.getElementByID('LogInButton');
It should be:
document.getElementById('LogInButton');
Here is the official docs: https://developer.mozilla.org/en-US/docs/Web/API/Document/getElementById

</script>
</html>
Let's say I fill values in my input text as red green and blue and hit submit. Likely, it should make a POST request to /lol endpoint and submit the values under keyword= param. But it doesn't work.
Is there some issue with Token-Field Library ? How do I make post request of the values user input ?
You need to assign a name attribute to the input element. Form elements without a name will not be included in the request.
Following will work,
<input type="text" class="form-control" name="keyword" id="keyword" value="red,green,blue" />
The W3C specification mandates that every form input element have a name attribute specified. Otherwise, that element will not be processed. Source

Like a slider documentation -- You have 2 ways to use it
var mySlider = new Slider('#ex6');
OR
$('#ex6').slider();

Note: On my examples I used slider CDN so if your code
not working with your css , js paths you can use CDN instead or check
your paths
Alright, I apologize for not writing my question clearly, so the issue is not from the html file, but from the framework that I am working on.
Since I was using electron, if you just load the html code, the application can not recognize the js files in the html unless you add the following code before and after your scripts.
<!-- Insert this line above script imports -->
<script>if (typeof module === 'object') {window.module = module; module = undefined;}</script>
<!-- normal script imports etc -->
<script src="scripts/jquery.min.js"></script>
<script src="scripts/vendor.js"></script>
<!-- Insert this line after script imports -->
<script>if (window.module) module = window.module;</script>
Here's the source of the solution on this issue
Write slider instead of Slider
$("#ex6").slider();
And make sure the bootstrap-slider.js file is placed in assets/js/ folder
I have a simple web page which takes the value from the input box and passes it to the next page or form. Only problem is I don't know how to use jquery to get the value and assign it as a php value. I want to pass this value in into the URL

print
"<input type='text' class='form-control' id='usr'>".
"<a href='calculate.php?id={45}&tt='><button class='btn btn-success'>Calculate</button></a>";
?>
How do I pass the result value to "<a href='calculate.php?id={45}&tt='>, where tt is the value of the box?
Thanks
You should use a function to get the value and change the button to use that function:
So your final php code would be:

<script>
function calculate() {
var tt = $("#usr").val();
location.href = "calculate.php?id={45}&tt=" + tt;
}
</script>
<input type='text' class='form-control' id='usr'>
<button class='btn btn-success' onclick="calculate()">Calculate</button>
I removed the <php? print... because it's just plain html.
Using jquery is very simple for such scenario.
<?php
print
"<input type='text' class='form-control' id='usr'>".
"<a id='button' href='#'><button class='btn btn-success'>Calculate</button></a>";
?>
Here I have added id attribute to your anchor tag or link whatever you call it.
Now the jquery part:
<script type="text/javascript">
$(document).ready(function(){
var usr = $("#usr").val();
$("#button").attr("href","calculate.php?id={45}&tt="+usr);
});
</script>
Or If you want the url to be changed when the value of that particular text field changes then you may try following.
<script type="text/javascript">
$(document).ready(function(){
$("#usr").change(function(){
var usr = $("#usr").val();
$("#button").attr("href","calculate.php?id={45}&tt="+usr);
});
});
</script>
Hope this helps. If you want to learn more about jquery change event then you can have a look at jQuery Change Event
