Let me check to see if I have this correct. You want each type of user (teacher or student) to have a calendar and scheduler. If you never need to share calendars or schedules then having the calendar/schedule as a capability of the user is a clean way to manage this in Mongo.

Uff, I'm so sorry for my english. It's so hard for me explain my problem in not native language.
I have users, users can access to his data, and his data are students, teachers, shceduler, calendar, ...
This means, every user have his own data, and this data it's for app tables.
I have a mongodb, no sql.
Thanks, I hope I explained better now.

I am trying to implement pinch zoom in zoom out in js.
I am almost there, as I have calculated how to detect pinch zoom in zoom out in js using touch events.
....
var dist1=0;
function start(ev) {
if (ev.targetTouches.length == 2) {//check if two fingers touched screen
dist1 = Math.hypot( //get rough estimate of distance between two fingers
ev.touches[0].pageX - ev.touches[1].pageX,
ev.touches[0].pageY - ev.touches[1].pageY);
}
}
function move(ev) {
if (ev.targetTouches.length == 2 && ev.changedTouches.length == 2) {
// Check if the two target touches are the same ones that started
var dist2 = Math.hypot(//get rough estimate of new distance between fingers
ev.touches[0].pageX - ev.touches[1].pageX,
ev.touches[0].pageY - ev.touches[1].pageY);
//alert(dist);
if(dist1>dist2) {//if fingers are closer now than when they first touched screen, they are pinching
alert('zoom out');
}
if(dist1<dist2) {//if fingers are further apart than when they first touched the screen, they are making the zoomin gesture
alert('zoom in');
}
}
}
document.getElementById ('zoom_here').addEventListener ('touchstart', start, false);
document.getElementById('zoom_here').addEventListener('touchmove', move, false);
now i want to translate the img to keep zooming
n i want algo for translate

Probably by writing some code.

You're going to have to describe, in detail, what a "campaign open window" is.

I am trying to number each result so that it says:
City #1 is Los Angeles.
City #2 is...
City #3 is...
... and so on.
I was thinking that I had to write something inside the for loop?
<html>
<body style="text-align: center;">
<h2 id="hi">Enter Your Five Favorite Cities</h2>
<form class="" action="index.html">
<input type="text" name="favoriteCities[]" value="" /><br>
<br>
<input type="text" name="favoriteCities[]" value="" /><br>
<br>
<input type="text" name="favoriteCities[]" value="" /><br>
<br>
<input type="text" name="favoriteCities[]" value="" /><br>
<br>
<input type="text" name="favoriteCities[]" value="" /><br>
<br>
<button type="button" name="button" onclick="favoriteCities()">Submit</button>
</form>
<h3 id="hi">Results</h3>
<p id="output"></p>
<script type="text/javascript">
var r = "";
function favoriteCities() {
var input = document.getElementsByName('favoriteCities[]');
for (var i = 0; i < input.length; i++) {
var a = input[i];
r = r + "City #" + "???" + "is " + a.value + ("<br>");
}
document.getElementById("output").innerHTML = r;
}
</script>
</body>
</html>
I am using Notepad++.

You already have a number, which you're using as the index in the for loop. You just need to add 1 to get the numbers to start at 1 instead of 0.
You'll also want to HTML-encode the user-supplied data so that it displays properly. The simplest way to do that is to create an element and set its innerText property.
const favoriteCities = function() {
const output = document.getElementById("output");
output.innerHTML = "";
const input = document.getElementsByName("favoriteCities[]");
for (let i = 0; i < input.length; i++) {
const div = document.createElement("div");
div.innerText = `City #${i + 1} is ${input[i].value}`;
output.appendChild(div);
}
};

Print the following pattern using for loop

You just need a loop that counts down from 5 to 1 and then up back to 5. Give it a try. If you need specific assistance with Javascript then go to JavaScript Tutorial[^].

You have edited every question you have ever posted to read "I got it txh", after you have been given the answer.
This is not only extremely rude, it will NOT prevent your teachers from discovering your attempt to cheat on your homework.

export class myClass implements OnInit {
counter=0;
static counter:any;
onListItemClick(PackDef: PackDefinition): void {
this.itemClicked.emit(PackDef);
this.counter++;
console.log(this.counter);
and
<pre>import { myClass } from '../../../';
dialogRef.afterClosed().subscribe((result: any) => {
this.saveMyMethod();
console.log("Final1"),
console.log(myClass.counter);
});
saveMyMethod(): void {
console.log("Final2"),
console.log(myClass.counter);
Do you know why I cant have correct counter after "Final1" or "Final2"? but I have a correct counter in myClass.

Hello Everyone,
I am in a Core Technologies class and Javascript coding is a topic that I don't fully understand. For our coding assignment, we were directed to www.w3schools.com where we could try different codes, run them and see how they work. When given the original code, I understand how to change it and I see how the modification changes what is displayed but, I don't fully understand the basic elements of the code and how to start from scratch to write one. Can anyone help me out with understanding the basic elements of a code starting from scratch or could you suggest a website that can explain it from scratch? Thank you in advance for any help you can offer.
Regards,
John

W3Schools Online Web Tutorials[^] is probably the best site for learning web based technologies. So go to the Javascript section and follow it through, it will explain everything.

First, welcome to web development. It's an industry that only continues to grow. We'd be happy to help with specific questions.
As far as just getting started with all the concepts, nothing beats a good book. The website linked is great, but usually book authors take much more time to explain things.
I wish I could recommend a good current book, but I started web development back in the 90s. That crap is out of print by now I'm sure. But, once you do get the concepts, I can recommend a reference website. The Mozilla foundation (same peeps that make FireFox) have an online resource called the Mozilla Developer Network (MDN).
Learn web development | MDN[^]
It will literally be one of the best reference sites to use, once you get the concepts down.

Shouldn't the comparisons look something like,
if (a == b)
{
}
"the debugger doesn't tell me anything because this code compiles just fine" - random QA comment
"Facebook is where you tell lies to your friends. Twitter is where you tell the truth to strangers." - chriselst
"I don't drink any more... then again, I don't drink any less." - Mike Mullikins uncle

As you suggest, the '=' should be '=='. As is
if (randomNum = 0) sets randomNum to 0 and the 'if' effectively becomes 'if (0)' which is a falsy result (not false, but treated false), so it carries on. Then
else if (randomNum = 1) sets randomNum to 1 and the 'if' effectively becomes 'if (1)' which is a truthy result (not true, buth treated as true) so it succeeds.
Many people may jump up and down and say it shows what a dreadful language JavaScript is; but the same thing is valid in many other languages, e.g. C, C#, Java.

You need to show the code you have for people to help you. No one here is going to write your complete assignment.

function colorSelector (colorCode) {
let randomNumber = Math.floor((Math.random() * 100));
if (randomNumber < 10) {
console.log("green");
}
else if (randomNumber >= 10 && randomNumber < 19) {
console.log("yellow");
}
else if (randomNumber > 19) {
console.log("blue");
}
return (randomNumber);
}
console.log(colorCode);
This is how far I got. Im confused what should be inside the function and what should we outside. Im also not sure if im using the return operator the right way.
