Window.showModalDialog() does not work in a for loop JavaScript

I am trying to introduce showModaldialog in a for loop, I have changed the names of the id's so that, being different, it can be opened as many times as the user requests:
for (i = 0; i < number; i++) {
cerrado=0;
cerrado = window.showModalDialog(ventana, 'url' ,'nuevadiag'+id);
if (cerrado==null){
i=numero;
}
}
the problem is that it only opens once and nothing else, any ideas?, this is the jquery function of window.showModalDialog():
(function() {
window.spawn = window.spawn || function(gen) {
function continuer(verb, arg) {
var result;
try {
result = generator[verb](arg);
} catch (err) {
return Promise.reject(err);
}
if (result.done) {
return result.value;
} else {
return Promise.resolve(result.value).then(onFulfilled, onRejected);
}
}
var generator = gen();
var onFulfilled = continuer.bind(continuer, 'next');
var onRejected = continuer.bind(continuer, 'throw');
return onFulfilled();
};
window.showModalDialog = window.showModalDialog || function(pantalla, url, arg, opt,id) {
//documento= window.parent.parent.document;
// alert(pantalla);
documento= pantalla.document;
// alert(documento.body);
url = url || ''; //URL of a dialog
arg = arg || null; //arguments to a dialog
opt = opt || 'dialogWidth:300px;dialogHeight:200px;color:#ff6600;'; //options: dialogTop;dialogLeft;dialogWidth;dialogHeight or CSS styles
opt = opt+ ';color:#ff6600;';
var caller = '';
if(arguments.callee.caller != null ){
caller = arguments.callee.caller.toString();
}
var dialog = documento.body.appendChild(document.createElement('dialog'));
dialog.setAttribute('style', opt.replace(/dialog/gi, ''));
dialog.setAttribute('id',id );
var idDialogClose="dialog-close"+id;
var idDialogBody = 'dialog-body';
if( id!=undefined && id!=null && id!=''){
var idDialogBody ='dialog-body'+id;
}
dialog.innerHTML = '×<iframe id="'+idDialogBody+'" src="' + url + '" style="border: 0; width: 100%; height: 100%;border-top: 3px solid #ff6600;border-bottom: 3px solid #ff6600;border-left: 3px solid #ff6600;border-right: 3px solid #ff6600;margin-right: -10px;margin-bottom: -10px;"></iframe>';
documento.getElementById(idDialogBody).contentWindow.dialogArguments = arg;
documento.getElementById(idDialogClose).addEventListener('click', function(e) {
e.preventDefault();
dialog.close();
});
dialog.showModal();
//if using yield or async/await
if(caller.indexOf('yield') >= 0 || caller.indexOf('await') >= 0) {
return new Promise(function(resolve, reject) {
dialog.addEventListener('close', function() {
var returnValue = documento.getElementById(idDialogBody).contentWindow.returnValue;

});
}

var nextStmts = caller.split('\n').filter(function(stmt) {

return isNext = true;
return false;
});
dialog.addEventListener('close', function() {
var returnValue = documento.getElementById(idDialogBody).contentWindow.returnValue;
documento.body.removeChild(dialog);

js for newest chat message order

in my chat extension for phpBB, i use ajax for the js with a little jquery mixed in. i'm setting it up for users to select if they want the newest messages at the top or the bottom in accordance to their setting in their user control panel. the php side of it is done and works well but the js is still adding the new message at the top, ignoring the sort order in the php.
in the php. note that the sort order is set with this line
ORDER BY c.message_id ' . ($this->user->data['user_ajax_chat_messages_down'] ? 'DESC' : 'ASC');
i can't post the php in this post as the body is limited to 30000 characters. so i will post it if needed.
here is the js that does all the work

what needs to be changed to accomplish what i'm trying to do? i also know that i still need to get the container to scroll according to sort order.
if more info is needed, please let me know

got it all sorted with the following part
var content = chat.innerHTML;
chat.innerHTML = isDown ? (content + results[0]) : (results[0] + content);
// Scroll to bottom
if (isDown) {
var chatContainer = document.querySelector('.shout-body');
chatContainer.scrollTop = chatContainer.scrollHeight;
}```

How does JS code execution can be blocked by client?

I've got some JS code that runs eventually - I've got no idea whats's wrong.
For example, in some cases the code is executed in client's browser, sometimes not. We have a server indicating if a client reached the server from browser. 2/15 of clients don't get the job done.
Here's the code example.
__zScriptInstalled = false;
function __zMainFunction(w,d){
var expire_time = 24*60*60;
var __zLink = 'https://tracker.com/track/4c72663c8c?';
__zLink += '&visitor_uuid=7815528f-5631-4c10-a8e4-5c0ade253e3b';
var __zWebsitehash = '4c72663c8c';

var clicks_limit = 1;
var __zSelector = "*";

name += '_' + __zWebsitehash;
var matches = document.cookie.match(new RegExp(
"(?:^|; )" + name.replace(/([\.$?*|{}\(\)\[\]\\\/\+^])/g, '\\$1') + "=([^;]*)"
))
return matches ? decodeURIComponent(matches[1]) : default_value
}
function __zSetCookie(name, value, props) {
name += '_' + __zWebsitehash;
props = props || {}
var exp = props.expires
if (typeof exp == "number" && exp) {
var d = new Date()
d.setTime(d.getTime() + exp*1000)
exp = props.expires = d
}
if(exp && exp.toUTCString) { props.expires = exp.toUTCString() }
value = encodeURIComponent(value)
var updatedCookie = name + "=" + value
for(var propName in props){
updatedCookie += "; " + propName
var propValue = props[propName]
if(propValue !== true){ updatedCookie += "=" + propValue }
}
document.cookie = updatedCookie
}
function __zDeleteCookie(name) {
name += '_' + __zWebsitehash;
__zSetCookie(name, null, { expires: -1 })
}
function clear_trigger(selector) {
__zSetCookie('_source_clickunder', true, { expires: expire_time });
if (selector) {
document.querySelectorAll(selector).removeAttribute('onclick');
}
}

xhr.onload = success;
xhr.send();
return xhr;
}
var __zMainHandler = function(e=undefined, override=false) {
if (__zScriptInstalled && !override){
console.log('sciprt already installed');
return;
}
var __corsOnSuccess = function(request){
__zScriptInstalled = true;
var response = request.currentTarget.response || request.target.responseText;
var parsed = JSON.parse(response);
if (! parsed.hasOwnProperty('_link')){
return;
}

if (parsed.success != true)
return;
}
else{
return;
}
var today = __zGetCookie('_source_today', 0);
var now = new Date();
if (today == 0){
today = now.getDate();
__zSetCookie('_source_today', today);
}
else if (today != now.getDate()){
today = now.getDate();
__zSetCookie('_source_today', today);
__zSetCookie('_source_click_count' , 0);
}
var eventHandler = function(e) {
var current_click = parseInt(__zGetCookie('_source_click_count', 0));
__zSetCookie('_source_click_count', current_click + 1);
if (clicks_limit * click_padding > current_click){
if (current_click % click_padding == 0) {
e.stopPropagation();
e.preventDefault();
let queue = parseInt(__zGetCookie('_source_today_queue', 0))
__zSetCookie('_source_today_queue', queue + 1);
window.open(__zLink+'&queue=' + queue, '_blank');
window.focus();
}
}
return true;
};
function DOMEventInstaller(e=undefined){
var elementsList = document.querySelectorAll(__zSelector);
for (var i = 0; i != elementsList.length; i++){
elem = elementsList.item(i);
elem.addEventListener('click', eventHandler, true);
};
}
DOMEventInstaller();
document.body.addEventListener('DOMNodeInserted', function(e){
DOMEventInstaller(e.target);
e.target.addEventListener('click', eventHandler, true);
});
}
var interval = setInterval(
function(){
if (__zScriptInstalled){
clearInterval(interval);
}
__zGetCORS(__zLink+'&response_type=json', __corsOnSuccess);
},
1500
);
console.log('script installed');
};
__zMainHandler();
document.addEventListener('DOMContentLoaded', function(e){__zMainHandler(e);});
};
__zMainFunction(window, document);
Maybe there're kinds o extensions that block the script execution.

Almost all modern browsers have options to disable js .
e.g. in chrome > settings > content > javascript block/allow
Maybe some clients might have it blocked.
But by default its allowed by browsers.
Also most browsers have do not track option.
Hope it helps.

Data gets lost in a java script and .Net based chat app

This code has landed on my lap, and I don't have any clue what might be going on. The code is a Java Script in an ascx file as part of a chat system. The problem is that the chat content are lost after about 10 minutes. I don't know if this has anything to do with caching or not. I would like to know what might be causing the loss of chat content in this code.

Javascript in asp .Net

I'm getting WebResource error in my asp.Net page:
var __pendingCallbacks = new Array();
Microsoft JScript runtime error: 'Array' is undefined
I have no idea what might cause this to happen. Isn't Array part of Javascript itself? Any help would be appreciated.
EDIT
The problem is that this isn't code that I wrote, it's built into the page structure in asp.Net.
EDIT
The problem only occurs in IE9 and only when run in IE9 mode (not compatibility)
Code:
(This is dynamically generated code, sorry for the length. Problem is about halfway down)
function WebForm_PostBackOptions(eventTarget, eventArgument, validation, validationGroup, actionUrl, trackFocus, clientSubmit) {

This happens because we have this setup
<collapsible panel>
<iframe>
<script>
</script>
</iframe>
</collapsible panel>
When the page loads, the panel being shown forces the script inside the iframe to be dragged through the DOM before the javascript libraries are loaded. This seems to be a change in that was made for IE9. I have yet to fine a way around this issue but at least I know the cause. A temporary workaround is to force the compatibility of the page to IE8 using a meta tag in case anybody else runs into this issue.

The problem was fixed when I removed the SRC attribute from the iframe and I added onOpen event to jQuery's dialog:
open: function(){
document.getElementById("iframename").src = "page.aspx";
}
