I want add to firebase SDK in external JavaScript file and link my JavaScript file with index.html and I want to create all functions in an external JavaScript file but after putting code of SDK my function is not working and no output appears in the console.
//code of main.js
import { initializeApp } from "firebase/app";
// Your web app's Firebase configuration
const firebaseConfig = {
apiKey: "AIzaSyBbXn11EFZ-B4UutkGbbvFFhddnqWFpDWc",
authDomain: "test-app-c0aed.firebaseapp.com",
projectId: "test-app-c0aed",
storageBucket: "test-app-c0aed.appspot.com",
messagingSenderId: "797893271922",
appId: "1:797893271922:web:5fc8bade62add0ca573deb"
};
// Initialize Firebase
const app = initializeApp(firebaseConfig);
const provider = new firebase.auth.GoogleAuthProvider();
// event and function for login button
document.getElementById('login').addEventListener("click",login);
function login()
{
console.log('login');
firebase.auth().signInWithPopup(provider).then( res => {
console.log(res);
})
}
// event and function for log out button
document.getElementById('logout').addEventListener("click",logout);
function logout(){
console.log('logout');
}
//code of index.html

I want to get the data from my database using JavaScript and firebase, I have configured the firebase connection, but it gives me error: db is not defined.
I think the problem comes from the database configuration with firebase.
because the tutorial configuration is different than that.
I found this configuration in a post : previous solution
db.collection('courses').get()
.then(res => console.log(res))
.catch(err => console.error(err))

const db = getFirestore(firebase);
You define db as the very last thing in your module. It then immediately falls out of scope and will be garbage collected.
If you want to use it, then you need to do so in the same scope.
Presumably the JS you put in the JavaScript box of your live demo is from <script src="script.js"></script>. Move it into the module where you define db.
I'm developing a vue3 project.
main.js;
import { createApp } from "vue";
import App from "./App.vue";
const app = createApp(App);
import store from "./store";
app.use(store);
import router from "./router/index";
app.use(router);
...
//just try...
app.mount("#app");
and my public/index.html

And my App.vue;
<template>
<button #click=openNewPage()>create new page</button>
<span>{{message}}</span>
<router-view />
</template>
<script>
methods:{
openNewPage(){
var t = window.open('second.html','newMonitor','height=700,width=700,left=100,top=100,resizable=yes,scrollbars=yes,toolbar=yes,menubar=no,location=no,directories=no, status=yes');
}
}
</script>
my store object;
export default createStore({
state: {
message:'Hello'
}
});
and my second.html;
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta http-equiv="Cache-Control" content="no-store" />
<meta http-equiv="Pragma" content="no-cache" />

</head>
<body>
<div id="appSecond" style="height:100%">
<template>
<span>{{message}}</span>
</template>
</div>
</body>
</html>
When I open the second screen with the OpenNewPage method, I cannot access both the store object and the components I want to use do not work. I was try it;
second.js
const app2 = createApp({
});
export { app2 };
and my method
import { app2 } from "../second.js";
openNewPage(){
var t = window.open('second.html','newMonitor','height=700,width=700,left=100,top=100,resizable=yes,scrollbars=yes,toolbar=yes,menubar=no,location=no,directories=no, status=yes');
if (t) {
t.onload = function () {
t.window.app = app2;
app2.mount("#appSecond");
}
}
}
Somehow I try to run in second.html but I get a warning like "[Vue warn]: Failed to mount app: mount target selector". The code didn't work anyway. Can you help me?
openNewPage() can't run a script for the newly opened page; only the new page could run its own scripts. When openNewPage() tries app2.mount(), it's running that code on its own page (not the new one), leading to the error you observed.
Solution
Remove the mounting code from openNewPage() so that it only opens the new page:
export default {
openNewPage() {
window.open('second.html', …);
}
}
Update second.html to load the script that mounts the app, and remove the unnecessary <template> within the <div id="appSecond">:
<body>
<div id="appSecond" style="height:100%">
<span>{{message}}</span>
</div>
<script src="./second.js"></script>
</body>
In second.js, add the code that mounts your app:
// second.js
import { createApp } from 'vue'
import App from './App.vue'
import store from './store'
createApp(App).use(store).mount('#appSecond')
My file directory is:
chartTesting
index.html
chart1.js
chart2.js
I am trying to desplay the chart in my website using mongodb chart embedding sdk,
I have index.html, chart1.js and chart2.js file in same folder.
I have been stuck in this problem for days,
I have change the script src in many different ways.

I'm trying to request my firebase from a tizen web app. So I have added the firebase config to script section, then I need to access my firebase object from the javascript but I don't know how to proceed, how to declare 'firebase' variable to be linked to the firebase lib? here is my code :
tizen studio screenshot
or
function init() {
// How to get firebase object ?
firebase.database()
.ref('/test')
.once('value').then(function(snapshot) {
var value = snapshot.val();
document.querySelector("#foo")
.innerHTML = value;
});
...
}

<title>Hello Tizen</title>
<link rel="stylesheet" href="css/style.css">
<script src="https://www.gstatic.com/firebasejs/4.0.0/firebase.js"></script>
<script>

var config = {
apiKey: "blabla",

firebase.initializeApp(config);

EDIT :
adding <access origin="*" subdomains="true"></access> to config.xml solve my internet connection issue
You seem to have forgotten to put these scripts as well
<script src="https://www.gstatic.com/firebasejs/4.0.0/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/4.0.0/firebase-database.js"></script>
firebase-app.js should always come first.
Hi I'm trying to get the LinkedIn api working at a basic level. Where I make an HTML page that shows the LinkedIn sign in button. I followed the steps on the LinkedIn developer page and copied the code directly. I'm wondering if I have an issue with the OAuth2.0?
