Get html element - javascript

I try to accomplish to make a chatbot but sounds like I have a problem on my code but no errors come up. I tried to debug the code but no errors come. I tried to get the message on the chat container, but in the main.js -when I try to access the input type text value. When I try let messageText = textbox.value; the .value does not exist. I can't see any error. Apparently this is my index.html file.
Also I have try to change to var textbox = document.getElementById('mytextbox').value; when clicked nothing happens and the text inside of the input is not created in chat container.

Your JS code is fine.
The issue is <script scr="js/main.js"></script>
You have a typo in scr="js/main.js" should be src="js/main.js


var sendBtn = document.getElementById('sendBtn');
var textbox = document.getElementById('mytextbox');
var chatContainer = document.getElementById('chatContainer');
function sendMessage(messageText){
var messageElement = document.createElement('div');
messageElement.classList.add('w-50');
messageElement.classList.add('float-end');
messageElement.classList.add('shadow-sm');
messageElement.style.margin ="10px";
messageElement.style.padding ="5px";
messageElement.innerHTML = "<span>You: </span>"+
"<span style='margin-top:10px; padding:10px'>"+ messageText +"</span>";
chatContainer.appendChild(messageElement);
}
sendBtn.addEventListener('click', function(e){
let messageText = textbox.value;
textbox.value = "";
sendMessage(messageText);
});

You got some typos in your HTML file, remove the " from spans closing tag in <span style="margin-top: 10px; padding: 10px;">How are You?</span">
and
<span style="margin-top: 10px; padding: 10px;">Great</span">
After that the messages appear and it seems to work.
EDIT:
I missed the miss spell on the script tag where you miss spelled src with scr thanks for pointing it out.

how to connect a navigation bar (<nav>) with HTML files in google appscript?

I am developing a code where I have different option levels and I want one of those options to display a nav bar with two tabs: one to search customers and the other to add customers, I already have the loadView, loadCustomersView and loadAddCustomerView function in my clients.html doc, but it does not display the content when I click on the tabs.
How can I make the navigation bar with the search and add clients options show me what is in search.html and addcustomer.html? (see image 3)
step 1, click in opcion1
step 2, click in opcion 1.1
step3, have a nav bar with 2 options: search and add customers
here is a copy of all my files.
codigo.gs
function doGet() {
return HtmlService.createHtmlOutputFromFile('Index');
}
function getOpcion1() {
var html = HtmlService.createHtmlOutputFromFile('opcion1').getContent();
return html
}
function getObtenerClientes() {
var html = HtmlService.createHtmlOutputFromFile('clientes').getContent();
return html
}
function loadPartialHTML_(partial) {
const htmlServ = HtmlService.createTemplateFromFile(partial);
return htmlServ.evaluate().getContent();
}
function loadSearchView() {
return loadPartialHTML_("search");
}
function loadAddCustomersView() {
return loadPartialHTML_("addcustomer");
}

is it possible to refresh the same content in two different html pages?

i have this code, witch is basically a click counter in javascript.
my question is, is it possible to show the "clicks" in two different pages?
My goal is to make two identical pages, but the second one is just to show the click counting, as the first one is to click and at the same time to show the counting.
i dont have much experience in programing.
all help is much apreciated :)

document.getElementById("clicks").innerHTML = clicks;
};
function bye() {

document.getElementById("clicks").innerHTML = clicks;
};

Only if one page opens the other one*.
If you use var w=window.open() you can access the other page's document in w.document. And, from the second page, you can access the first one's in window.parent.document.
*That is with js only. If you can use a server language you could make something more complex using ajax or even sockets.

Bootstrap modal window won't open because of interference with other elements

I can't seem to figure out why bootstrap's modal window isn't popping up.
I've looking into other similar questions and I still can't get it to work.
I've tried the process of elimination and try to eliminate all my scripts (except the bootstrap script) and it still won't open. Same with my CSS files. I also had inputted manual code for a modal window (before I incorporated bootstrap) so I was worried that the id="modal" from other modals would interfere. I deleted those too and nothing worked.
Here is my codepen, I've commented the sections the modal window code starts: https://codepen.io/eylenkim/pen/KKwMPLm

There are 2 separate issues that are preventing the modal from showing up.
1) The first issue is with your code
The bootstrap library you use returns 404.
How to check if it's happening for you?
Open your browser's inspector, and press CTRL+SHIFT+I
You will see:
Failed to load resource: the server responded with a status of 404 () eylenkim/fullpage/bootstrap-4.3.1-dist/css/bootstrap.css
In fact, this happens for a lot of your relative URLs.
Solution
Replace links to Bootstrap libraries with working ones, eg. from https://getbootstrap.com/
The ones I used in my testing of your code:
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous">
<script src="https://code.jquery.com/jquery-3.4.1.slim.min.js" integrity="sha384-J6qa4849blE2+poT4WnyKhv5vZF5SrPo0iEjwBvKU7imGFAV0wwj1yYfoRSJoZ+n" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/popper.js#1.16.0/dist/umd/popper.min.js" integrity="sha384-Q6E9RHvbIyZFJoft+2mJbHaEWldlvI9IOYy5n3zV9zzTtmI3UksdQRVvoxMfooAo" crossorigin="anonymous"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.min.js" integrity="sha384-wfSDF2E50Y2D1uUdj0O3uMBJnjuUD4Ih7YwaYd1iqfktj0Uod8GCExl3Og8ifwB6" crossorigin="anonymous"></script>
See gist for minimum code sample for a modal here: https://codepen.io/edwin-chua/pen/rNaLOEg
Once you fix the link problem, you will run into the second issue.
2) The second issue is with your stylesheet
Once you fixed your code as I suggested, you get a dark overlay with no modal.
Removing the reference to https://eylenkim.github.io/ArtByEylen/StyleSheet.css allows the modal to show up, so something in here is interfering with the modal's css.
Here is a working pen: https://codepen.io/edwin-chua/pen/QWwEyyZ
Separate Problem
You seem to have imported some libraries twice, once in the Codepen UI, and once in the HTML file. This will cause you debugging headaches. Make sure you only import them once. Since you are building an entire webpage, I suggest putting all of it in the HTML file.
also see JS tab
And
Further Comments
This section of code seems to be for closing the modal? If so, it probably isn't required, as Bootstrap automatically binds the click events.
<!--Modal - Dialog Boxes -->
<script type="text/javascript"> const modals = Array.from(document.querySelectorAll('.modal'));
const triggers = Array.from(document.querySelectorAll('.trigger'));
var closeButton = document.querySelector(".close-button");
//if a trigger is clicked then...
for (const trigger of triggers) {
trigger.addEventListener('click', toggleModal);
}
// .. then toggle it's modal
function toggleModal(event) { event.target.closest('.trigger').querySelector('.modal').classList.toggle("show-modal"); }
// check if the clicked element is a modal, or in a modal
function windowOnClick(event) {
if (modals.some((modal) => modal.contains(event.target))) {
toggleModal();
}
}
</script>

How can I make a multiple button "click to reveal" work in javascript?

I'm trying to make a relatively simple JavaScript file that allows me to click one of 5 buttons and information is revealed on the screen. Currently, I have it working a single reveal but the others do not appear.
Simply put the goal would be to have it so that if I click "Selection 1" then the text "test 1" would appear, "Selection 2" and "test 2", so on and so on...
Any help would be much appreciated!

remove button type as "button1"
it must be only "button"
js:
var buttons = document.querySelectorAll('.btn-block');
buttons.forEach(function(button, index){
button.addEventListener('click', function(){
if(button.dataset.btn===`btn-${index}`){
document.getElementById(`select${index}`).classList.toggle('selecton');
}
});
});

You should do something like this:
<script>
$(() => {
$("button[type='button1']").on("click", () => {
$("#select1").toggleClass("selecton");
})
$("button[type='button2']").on("click", () => {
$("#select2").toggleClass("selecton");
})
$("button[type='button3']").on("click", () => {
$("#select3").toggleClass("selecton");
})
$("button[type='button4']").on("click", () => {
$("#select4").toggleClass("selecton");
})
})
</script>
There are many rooms for improvement with the code above. But one step at a time anyway.

How to fix input issue in CodeMirror

I'm trying to get code mirror to read and display the contents of a file into the textarea, but everytime I load a file, it prints the contents as one line, ignoring all line breaks, and if I try to manually enter text into the text field, it automatically tabs every line after the first.
Proper text form file format:
Proper textarea styling:
Unfortunate result of selecting a file (this text format won't function with the compile button):

background-color: #cccccc;
}
.form-group{background-color:black;}
head {background-color: firebrick;}

nav {background-color: firebrick;}
a {color: snow;}
div {color: Azure}
/*italicizes and specifies which page you are on with color*/
a:hover{font-style: italic;}
/* alignment and font size */
head { font-size: 20pt}
h1 {text-align: center}
h2 {text-align: center}
h2 {font-size: 22pt}
.argname {font-size: 20px; text-decoration: underline; padding-top: 10px; background-color: black;}
.sides{ width:50%; float:left; padding-left: 20px}
.LI-profile-badge{
width:25%;

}
#footer {
position: fixed;
bottom: 0;
width: 100%;
height: 70px;
background-color: black;
text-align: center;
}
The fileUploadScript.js used to load the file into the text area:
document.getElementById("filebutton").addEventListener('change', function () {
var fr = new FileReader();
fr.onload = function () {
document.getElementById("textarea").textContent = this.result;
}
fr.readAsText(this.files[0]);
})

Hopefully someone can spot what's being done wrong.

CodeMirror has several Content manipulation methods. You will need to use the setValue method.
doc.setValue(content: string)
Set the editor content.
Please reference the following block of code for my suggestions.

More specifically, editor.setValue(this.result); is what got it working. Take a look at this JS Bin
In your fileUploadScript.js you must use editor.setValue().
document.getElementById("filebutton").addEventListener('change', function () {
var fr = new FileReader();
fr.onload = function () {
editor.setValue(this.result);
//document.getElementById("textarea").textContent = this.result;
}
fr.readAsText(this.files[0]);
})
You can't force the code into the textarea. It just won' work. You have to use the setValue method as shown above.
