How to Show Table from google speadsheet after login (Google Web App)

Everybody . I'm doing some mini web-app but I'm new in programming
,I followed tutorial from "Learn Google Spreadsheets" on Youtube but get a little bit confuse
My App is very simple
1.User login Page (Check Usercode and Pass from firebase) --- DONE!
2.Get data (get Usercode and find data row from spreadsheet) --- DONE!
3.Pass Object to Table --- Need help
var ss= SpreadsheetApp.openById('1l2Q7C5qBF7EsDInlHi1Bv76jeRJwWjixKteBkc8i3ik');
var PayrollSheet = ss.getSheetByName("ข้อมูลล่าสุด") ;
var Route = {} ;
Route.path = function(route,callback){
Route[route] = callback ;
}
function doGet(e) {
Route.path("Login",LoadLogin) ;
Route.path("Table",LoadTable) ;
if(Route[e.parameters.v]){
return Route[e.parameters.v]() ;
}else {
return render("Login") ;
}
}
function LoadLogin(){
return HtmlService.createTemplateFromFile('Login').evaluate() ;
}
function LoadTable(Usercode){
var TargetRow = GetRow(Usercode) ;
var Data = PayrollSheet.getRange(TargetRow,1,1,18).getValues().flat();
var Round = PayrollSheet.getRange(1,2,1,2).getValues().flat();
return render("Table",{array:Data,round:Round}) ;
}
function render(file,argsObject){
var tmp = HtmlService.createTemplateFromFile(file);
if(argsObject){
var keys = Object.keys(argsObject) ;
keys.forEach(function(key){
tmp[key] = argsObject[key] ;
});
} // END IF
return tmp.evaluate() ;
}
Javascript in html file
<script>
function LoginUser() {
var usercodeIn = document.getElementById("Usercode").value;
var passwordIn = document.getElementById("Password").value;
google.script.run.withSuccessHandler(function(User){
if(User != 'FALSE') // Found User
{
document.getElementById("errorMessage").innerHTML = "welcome " + User ;
google.script.run.LoadTable(usercodeIn) ;
}
else if(User == 'FALSE') //Not Found User
{
document.getElementById("errorMessage").innerHTML = "Wrong Password!";
}
}).checkLogin(usercodeIn,passwordIn);
}
</script>
After Login successful I try to run Loadtable(usercode) to render Table.html with data base on usercode but It only login and show success prompt , but not render Table.html
This is sound pretty easy, but I really don't know what to do ,So please help Thank you

Provided there are no Date objects in argsObject you could simply do tmp.argsObject = argsObject.
Code.gs
function render(file,argsObject){
var tmp = HtmlService.createTemplateFromFile(file);
if(argsObject){
tmp.argsObject = argsObject.
}
return tmp.evaluate() ;
}
Then in your templeted HTML.
<table>
<? for (let i = 0; i < argsObject.array.length; i++) { ?>
<tr><td><?= argsObject.array[i] ?></td></tr>
<? } ?>
</table>

Is there a way to stop Form from executing action and wait for ajax to complete executing?

Before customers can proceed to paypal, I have a quick check on the database to see if the items still available,. The problem im having is that while Ajax is executing. function check_availability continue executing and returns true to the Form onsubmit before the completion of Ajax. To fix that problem I kept calling the same function within. But I dont think that is the best possible option.
Here is the code:
<form onsubmit="return check_availability(0,0,1)" action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post" id="pp1">
function ajax_paypal(orders){
var htpr = new XMLHttpRequest();
var url = "Hi there";
var val = "orders="+orders;
htpr.open("POST", url, true);
htpr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
htpr.onreadystatechange = function(){
if(htpr.readyState == 4 && htpr.status == 200){
var sold_out_ids = htpr.responseText;
check_availability("continue", sold_out_ids, 0);
}
};
htpr.send(val);
}
function check_availability(str, sold_out_ids, n) {
if (str === "continue") {
if (sold_out_ids > 0) {
alert("One of your items has sold out! Sorry for any inconvenience");
location.reload();
return false;
} else {
return true;
}
}else if(n === 1){
var orders = [];
var x = document.cookie.split(';'); // your array of cookies
var i = 0;
x.forEach(item => {
//to make sure that item contains "order"
if (item.indexOf('order') > -1) {
var val = item.split("=");
orders[i] = val[1]+"o";
i++;
}
});
ajax_paypal(orders);
}
check_availability(0, 0, 0);//I keep calling this until Ajax is completed
}

You can use following code snippet to solve. This will be called on submit but before actual submit happen if you return true from here form will get submit to paypal. If you return false form won't get submit.
$('#pp1').submit(function() {
var submitOrNot=await callcheck_availability();
return true; // return false to cancel form submit
});
async function callcheck_availability(){
//your function goes here
}

JavaScript Chrome printing multiple screens

problem in Chrome printing multiple screens
the code below is designed to load records from a list of students and print the resulting screen for each student.
this works fine in browsers other than Chrome
Chrome does not display each students record result and thus prints multiple copies of just one student.
When the script finishes the last student record in the list is displayed so we know that the form request is being made successfully. It appears Chrome is not waiting for the form request to load or that it doesn't update the screen before getting to the print command.
function printAll() {
var stdsObj = document.getElementById('stds');
for ( var i = 0; i < stdsObj.options.length; i++ ) {
showRec(i)
printIframe("main")
}
}
function showRec(selRec) {
var recID = '';
var recName = '';
var recNum = '';
var stdsObj = document.getElementById('stds');
recID = stdsObj.options[selRec].value;
recName = stdsObj.options[selRec].text;
recNum = selRec +1;
document.getElementById('recID').value = recID;
document.getElementById('recName').value = recName;
document.getElementById('recNum').value = recNum;
document.getElementById('noCacheRec').value = Math.random();
document.recList.submit()
}
function printIframe(id) {
var iframe = document.frames ? document.frames[id] : document.getElementById(id);
var ifWin = iframe.contentWindow || iframe;
ifWin.focus();
ifWin.printMe();
return false;
}
The form recList loads data into iframe "main"
<form id="recList" name="recList" action="ru_cse_view.pl" target="main">
printMe is a function in the iframe "main" that prints the iframe
function printMe() {
window.print()
}

Dats my code, awfully long, huh?
Well anyways I got most of it from here, however I get an error on line 67 saying "TypeError: 'undefined' is not a function.".
I'm using Steroids (phonegap-like) and testing dis on an iPhone simulator. I'm sure it uses some cordova for the database work.
Thank you for your help :-)

Which jQuery version do you use? Because .live() was removed with jQuery 1.9 (http://api.jquery.com/live/). You should use .on() instead: http://api.jquery.com/on/

fetching xml data into a div via ajax and javascript

Building a chat app and I am trying to fetch all logged in user into a div with ID name "chat_members". But nothing shows up in the div and I have verified that the xml file structure is correct but the javascript i'm using alongside ajax isn't just working.
I think the problem is around the area of the code where I'm trying to spool out the xml data in the for loop.
XML data sample:
<member>
<user id="1">Ken Sam</user>
<user id="2">Andy James</user>
</member>
Javascript
<script language="javascript">
// JavaScript Document
var getMember = XmlHttpRequestObject();
var lastMsg = 0;
var mTimer;
function startChat() {
getOnlineMembers();
}
// Checking if XMLHttpRequest object exist in user browser
function XmlHttpRequestObject(){
if(window.XMLHttpRequest){
return new XMLHttpRequest();
}
else if(window.ActiveXObject){
return new ActiveXObject("Microsoft.XMLHTTP");
} else{
//alert("Status: Unable to launch Chat Object. Consider upgrading your browser.");
document.getElementById("ajax_status").innerHTML = "Status: Unable to launch Chat Object. Consider upgrading your browser.";
}
}
function getOnlineMembers(){
if(getMember.readyState == 4 || getMember.readyState == 0){
getMember.open("GET", "get_chat.php?get_member", true);
getMember.onreadystatechange = memberReceivedHandler;
getMember.send(null);
}else{
// if the connection is busy, try again after one second
setTimeout('getOnlineMembers()', 1000);
}
}
function memberReceivedHandler(){
if(getMember.readyState == 4){
if(getMember.status == 200){
var chat_members_div = document.getElementById('chat_members');
var xmldoc = getMember.responseXML;
var members_nodes = xmldoc.getElementsByTagName("member");
var n_members = members_nodes.length;
for (i = 0; i < n_members; i++) {
chat_members_div.innerHTML += '<p>' + members_nodes[i].childNodes.nodeValue + '</p>';
chat_members_div.scrollTop = chat_members_div.scrollHeight;
}
mTimer = setTimeout('getOnlineMembers();',2000); //Refresh our chat members in 2 seconds
}
}
}
</script>
HTML page
<body onLoad="javascript:startChat();">
<!--- START: Div displaying all online members --->
<div id="chat_members">
</div>
<!---END: Div displaying all online members --->
</body>
I'm new to ajax and would really appreciate getting help with this.
Thanks!

To troubleshoot this:
-- Use an HTTP analyzer like HTTP Fiddler. Take a look at the communication -- is your page calling the server and getting the code that you want back, correctly, and not some type of HTTP error?
-- Check your IF statements, and make sure they're bracketed correctly. When I see:
if(getMember.readyState == 4 || getMember.readyState == 0){
I see confusion. It should be:
if( (getMember.readyState == 4) || (getMember.readyState == 0)){
It might not make a difference, but it's good to be absolutely sure.
-- Put some kind of check in your javascript clauses after the IF to make sure program flow is executing properly. If you don't have a debugger, just stick an alert box in there.

You must send the xmlhttp request before checking the response status:
function getOnlineMembers(){
getMember.open("GET", "get_chat.php?get_member", true);
getMember.onreadystatechange = memberReceivedHandler;
getMember.timeout = 1000; //set timeout for xmlhttp request
getMember.ontimeout = memberTimeoutHandler;
getMember.send(null);
}
function memberTimeoutHandler(){
getMember.abort(); //abort the timedout xmlhttprequest
setTimeout(function(){getOnlineMembers()}, 2000);
}
function memberReceivedHandler(){
if(getMember.readyState == 4 && getMember.status == 200){
var chat_members_div = document.getElementById('chat_members');
var xmldoc = getMember.responseXML;
var members_nodes = xmldoc.documentElement.getElementsByTagName("member");
var n_members = members_nodes.length;
for (i = 0; i < n_members; i++) {
chat_members_div.innerHTML += '<p>' + members_nodes[i].childNodes.nodeValue + '</p>';
chat_members_div.scrollTop = chat_members_div.scrollHeight;
}
mTimer = setTimeout('getOnlineMembers();',2000); //Refresh our chat members in 2 seconds
}
}
To prevent caching response you can try:
getMember.open("GET", "get_chat.php?get_member&t=" + Math.random(), true);
Check the responseXML is not empty by:
console.log(responseXML);
Also you might need to select the root node of the xml response before selecting childNodes:
var members_nodes = xmldoc.documentElement.getElementsByTagName("member"); //documentElement selects the root node of the xml document
hope this helps
