Make Multiple Pages Of a chat website using html/Js

i cant make a page for a different room (like chat rooms and you can pick what room you are chatting in) but it wont work, this is a code from another person but everyone is asking him to add rooms to his chat app so i tried doing it but im stuck, (note: the code is unchanged and his code works perfectly fine) here is a link to his chat app: https://replit.com/#NigelIsCoding/chat?v=1 , thank you for help :)
my main.js code:

Wordpress click and search with autocomplete

I have a problem with implementing my working script into my website. The local self-made script works perfectly. It uses jQuery autocomplete. When I type in 3 letters it will display the results. When I click on the results it will auto search.
I am trying to implement this into my current search box but I can't get it to work. In my local file I get the answers from an array but in my Wordpress version am using Ajax request to get the answers.
I am not sure which arguments to use in my WordPress function. Who can help me?
My working file:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<link rel="stylesheet" type="text/css" href="jquery-ui.css">

<label for="states">Geef een naam op:</label>
<input id="states">
<button id="go" style="display: none;" >GO</button>
<div id="no-result" style="display: none;">State not found.</div>
<p id="resultaten"></p>
<script>
function weergeven() {
var x = document.getElementById("Medewerkers").value;
document.getElementById("resultaten").innerHTML = x;
}
</script>
</body>
</html>
Javascript
$("#states").keypress(function (event) {
if (event.which == 13) {
event.preventDefault();
btnGoClick();
}
});
$(function () {
var stateList = [{

select: function (event, ui) {
btnGoClick(ui.item.value);
}
});
});
function btnGoClick(value) {
document.getElementById("resultaten").innerHTML = value;
}
Where it need to work:
<script>
jQuery( document ).ready(function(){
jQuery('.autocompl').autoComplete({
source: function(name, response) {
jQuery.ajax({
type: 'POST',
dataType: 'json',
url: 'private link',
data: 'action=get_listing_names&name='+name,
success: function(data) {
response(data);
}
});
},
select: function (event, ui) {
console.log("Hij doet het");
}
});
});
function btnGoClick() {
console.log("Hij doet het")
}
</script>
Nothing is showing up on my console, no error or console.log

Jquery Autocomplete not supported by keyboard

Autocomplete is not working for keyboard keys but it is working for mouse.i couldnot select item by arrow keys and enter key.
Here is my code. please suggest me any idea. and how to change my selected item background colour in input field?
var triggered = false;
var trigger = "#";
jQuery(".inputbox").autocomplete({
source: function( request, response ) {
var term = request.term;
jQuery.ajax({
url: "/home/friends?q="+term,
dataType: "json",
success: function( data ) {
response( $.map( data, function( item ) {
// alert(item.value);
return {
label: item.name,
value: item.name }
}));
}
});
},
search: function() {
if (!triggered) {
return false;
}
},
select: function(event, ui) {
var text = this.value;
var pos = text.lastIndexOf(trigger);
this.value = text.substring(0, pos + trigger.length) +
ui.item.value;
triggered = false;
return false;
},
focus: function() { return false; },
delay: 0,
minLength: 0,
allowNewTags: false
}).bind("keyup", function() {
var text = this.value;
var len = text.length;
var last;
var query;
var index;
if (triggered) {
index = text.lastIndexOf(trigger);
query = text.substring(index + trigger.length);
$(this).autocomplete("search", query);
}
else if (len >= trigger.length) {
last = text.substring(len - trigger.length);
triggered = (last === trigger);
}
});

I recommend to use https://github.com/ghiden/angucomplete-alt. It have this feature implemented by default.

Autocomplete Textbox fetching suggestions from database?

I have created 2 autosuggest textboxes in which one is fetching data from server-side and another is fetching data from client-side.But server-side textbox is not working.Can anyone point out the error in my code.
Following is my HTML Code:
<html>
<link type="text/css" rel="stylesheet" media="all" href="jquery-ui-1.8.9.custom.css" />

<script type="text/javascript" src="languages.js"></script>
<body>
<label for="languagesClientInput">Select Language(client-side): </label>
<input id="languagesClientInput" />
<br />
<label for="languagesServerInput">Select Language (server-side): </label>
<input id="languagesServerInput" />
</body>
</html>
Following is Js Code:
$(function() {
var languages = [
"C",
"C++",
"Core Java",
"Advance Java",
"PHP",
".NET",
"XML",
"HTML",
"Javascript",
"jQuery",

"NetRexx",
"NPL",
"NXT-G"
];
$("#languagesClientInput").autocomplete( { source: languages });
$("#languagesServerInput").autocomplete( { source: "languages.php" });
});
Following is Php Code:
<?php
$searchTerm = $_GET['term'];
$languages = array(
"C",
"C++",
"Core Java",
"Advance Java",
"PHP",
".NET",
"XML",
"HTML",
"Javascript",
"jQuery",
"JSON",
"Ajax",

"Miranda",
"NetRexx",

);
function filter($language) {
global $searchTerm;
return stripos($language, $searchTerm) !== false;
}
print(json_encode(array_values(array_filter($languages, "filter"))));
?>

The array_filter function fails. If you remove it you will get the data you need.
I actually think you have made a mistake there by writing array_filter instead of just filter to call the function you wrote above.

Now open index.php in your localhost/server and test it. Follow the similar method with your wordlist.

does anyone can show me how can i call the methods add_tags() and remove_tags() ?
thanks

$("selector").tagfield({remove:someobject});
$("selector").tagfield({add:someobject});
but the "remove" thing will not work i think, since the second "if" in fn.tagfield watches for "options.remove" but removes the "options.add" ...
