When you write in the correct username and password it only puts it in the url and doesn't work.

I've been studying Angular.js for my term exams and was working on the following code related to Angular.js forms.
<!DOCTYPE html>

</head>
<body>
<div ng-app="formApp" ng-controller="formCtrl">
<form name="festForm" novalidate ng-submit="sendForm(x)">
<h2>Registration form for tech event</h2>
<table>
<tr>
<td>
<label for="fname">First Name</label>
<input type="text" name="fname" id="fname" ng-model="x.fname" >

</td>
</tr>
<tr>
<input type="submit" value="SUBMIT">
</tr>
</table>
</form>
<p>{{userdata}}</p>
</div>
<script>
var app=angular.module("formApp",[])
app.controller("formCtrl",function($scope){
$scope.userdata="";
$scope.sendForm=function(fest){
$scope.msg="Form Validated"
$scope.userdata=angular.copy(fest);
console.log(fest)
}
})
</script>
</body>
</html>
Following is the output of the following code
I am not able to understand the flow how my argument fest passed in the sendform function gets converted into javascript object.
I am very new to javascript. Using this provided HTML script:

<input type="submit" class="btn btn-info" value="Reverse" />

</form>
<script src="02-reverse.js"></script>
</body>
</html>
I need to accept the input and manipulate it before writing the output to a popup window. I understand the manipulation aspect, but the input and output is tripping me up. My very simple code does not produce any popup window or any result at all:
var num = document.getElementsById("input").value;
// do stuff to num
window.alert(num);
HTML
<form id="theForm">
<h2>Reverse</h2>
<div>
<label for="theNumber">Enter an 8-digit number: </label>
<input type="number" minlength="8" maxlength="8" min="10000000" max="99999999" id="theNumber" required autofocus />
</div>
<div>
<input type="submit" value="Reverse" />
</div>
</form>
JavaScript
var theForm = document.getElementById('theForm');
theForm.addEventListener('submit', function(event) {
event.preventDefault();
var theNumber = document.getElementById("theNumber").value;
if (theNumber.length < 8 || theNumber.length > 8) {
window.alert('Number must be 8 digits.');
} else {
// reverse number then display
window.alert(theNumber);
}
});

I want to create a form in HTML that can take the inserted Name by the user and then after pressing submit shows the corresponded value (Age) to that user. This is my code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" type="text/css" href="MyMain.css">
<script language="JavaScript">
function myFunction() {
document.getElementById('myshow').innerHTML =
document.getElementById("Name").value;
}
</script>
</head>
<body>
<div class="container">
<div>
<fieldset>
<form action="">
<div class="row">
<div form-group">
<label for="fname">Your Name: </label>
<input type="text" class="form-control" name="name" id="Name" placeholder="Jon" value="">
</div>
</div>
<div>
<input type="submit" class="button" onclick="myFunction();" value="Submit"<br/>
</div>
</div>
</form>
</fieldset>
</div>
</div>
<div class="container">
<fieldset>
<div>
<label>Age: </label>
<p><span id='myshow'></span></p>
</div>
</fieldset>
</div>
</body>
</html>
The problem is that after pressing submit the Name will be shown in the myshow span section(Age:) just
for a fraction of second and then it disappeares and url changes to localhost:5000/?Name=Jack rather than localhost:5000/the current path/?Name=Jack
You should use onSubmit on the form element to call the function and then return false.

function myFunction() {
document.getElementById('myshow').innerHTML =
document.getElementById("Name").value;
return false;
}
</script>
</head>
<body>
<div class="container">
<div>
<fieldset>
<form action="" onSubmit="return myFunction();">
<div class="row">
<div form-group">
<label for="fname">Your Name: </label>
<input type="text" class="form-control" name="name" id="Name" placeholder="Jon" value="">
</div>
</div>
<div>
<input type="submit" class="button" value="Submit"><br/>
</div>
</div>
</form>
</fieldset>
</div>
</div>
<div class="container">
<fieldset>
<div>
<label>Age: </label>
<p><span id='myshow'></span></p>
</div>
</fieldset>
</div>

</html>
Ps: you did not close the submit tag properly
I think that you don't need submit.
If you don't need to submit, You have to change this code.

I have a function with input var is name of Form and ID of input. Now I want to get the value of password input. The problem is I have some input with same ID but in different form. So I want a flexible way to get its value when I know its form.
I have tried
var x = Form_Name.ID_Name.value;
but it doesn't work. So please tell me how to get the value of password input by a flexible way. Thanks so much. Below is my code:
<html>
<head>
<meta http-equiv="content-type" content="text/html" />
<meta name="author" content="lolkittens" />
<script charset="utf-8" type="text/javascript">
function check(Form_Name, ID_Name)
{
alert(document.getElementById(ID_Name).value);
alert(Form_Name);
var x = Form_Name.ID_Name.value;
alert(x);
}
</script>

<input id="Pass" name="Pass" type="password" size="20"/>
</form>
<button value="click Me" onclick="check('MainForm','ID')"> Click Me </button>
</div>
</body>

I have created another button for you to get password.
<html>
<head>
<meta http-equiv="content-type" content="text/html" />
<meta name="author" content="lolkittens" />
<script charset="utf-8" type="text/javascript">
function check(Form_Name, ID_Name)
{
alert(document.getElementById(ID_Name).value);
}
</script>

<form name="MainForm" id="MainForm">
<input id="ID" name="ID" type="text" size="20"/>
<input id="Pass" name="Pass" type="password" size="20"/>
</form>
<button value="click Me" onclick="check('MainForm','ID')"> Click Me for ID </button>
<button value="click Me" onclick="check('MainForm','Pass')"> Click Me for Password</button>
</div>
</body>
</html>
Optimized way:
You can achieve it using the same button as well, by passing an array of ID's.
Let me know, I can help more on this.
Access username and password using it's id.

<head>
<meta http-equiv="content-type" content="text/html" />
<meta name="author" content="lolkittens" />
<script charset="utf-8" type="text/javascript">
function check()
{
var username = document.getElementById("ID").value;
var password = document.getElementById("Pass").value;
alert("Username: "+username+" Password: "+password);
}
</script>

I have tried to get this work for hours.
Both test pageinit and pageshow on row 1 in login.js with no response at all, but the page is still being loaded and I not getting any javascript error when I run it in FF.

From login.js (the part wish not running)
$("#loginPage").on('pageinit', function(){
alert("Hello world!");
console.log("loginPage is loaded");
checkPreAuth();
var form = $("#loginForm");
$(form).on("submit",handleLogin);
if(window.localStorage["username"] != undefined) {
$("#username", form).val(window.localStorage["username"]);
}
});
I hope the wisdom of stackoverflow can help me find why $("#loginPage").on('pageinit') not firing?
