Script stops working when I insert into another script - javascript

I have a problem that is killing me right now because I can't see why it isn't working. I have made a script in one file that works, but when I copy/paste it into the file that I want it to work in, it doesn't work.
Here's the script I just made:
<html>
<body>
<p id="myElement"></p>
<script>
if (window.location.hash == "#hello") {
document.getElementById("myElement").innerHTML = 'Vi har Hello';
} else {
document.getElementById("myElement").innerHTML = '';
}
</script>
</body>
</html>
Here it works, but when I insert it into the file that it was meant for it won't work. Here it is:
<html>
<head>
<title>...</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no">

</head>
<body id="top">
<div id="forside"></div>
<div class="bgded overlay" style="background-image:url('images/stor_1.png');">
<div id="pageintro" class="hoc clear">
<li>
<p></p><h2>Log ind</h2>
<p id="myElement"></p>
<script>
if (window.location.hash == "#hello") {
document.getElementById("myElement").innerHTML = 'Vi har Hello';
} else {
document.getElementById("myElement").innerHTML = '';
}
</script>
<div id="comments">
<font color="black">
<form action="proces.php" method="post">
<input class="form-control" type="text" id="name" size="22" name="username" placeholder="Brugernavn" required><br>
<input class="form-control" type="password" id="name" size="22" name="pass" placeholder="Kodeord" required><br>
<input type="submit" name="submit" value="Log Ind!">
</form>
</font><br>
<i class="fa fa-chevron-left" aria-hidden="true"> Tilbage til forsiden</i>
</div>
</li>
</div>
</div>
<?php include_once "footer.php"; ?>
<a id="backtotop" href="#top"><i class="fa fa-chevron-up"></i></a>
<script src="layout/scripts/jquery.min.js"></script>
<script src="layout/scripts/jquery.mobilemenu.js"></script>
</body>
</html>
What the script, I am inserting, does is to detect if #Hello is in the URL and if it is, it has to display some text... But it won't work.
Anybody who has an idea about what I could be doing wrong?


your code will only run once when your page document first time load, if you do want to check the hash every time its changed, it is better to put in a change callback.
please also be sure you jQuery relative path is right.
$(function() { // ensure you will execute script after document loaded
$(window).on('hashchange', function() { // put you code in side change callback.
if (window.location.hash == "#hello") {
document.getElementById("myElement").innerHTML = 'Vi har Hello';
} else {
document.getElementById("myElement").innerHTML = '';
}
});
});

try adding these

input validation does not work - form gets submitted anyway?

I'm creating a website with a form and I can't get the validation to work, and can't figure out what I'm doing wrong. I've tried everything I can think of. The PHP works and it will submit, but it will always submit, and won't stop itself from submitting.

In HTML all you have to do is give element input the attribute required.
If you wish for more advanced validation then you have to do it in javascript.

How to use jquery to go to the next page or window in my Electron app

I'm trying to create a login system. I want the system to take me to another page "page3.htm" when I press the login button. I have been trying to test my system in jquery, but the code below does not seem to work. Why is that?
The "login.js" file contains:
window.onload =function() {
var loginBtn = document.getElementById('go');
loginBtn.addEventListener('click',function(){
document.location.href = './page3.html';
});
}
The "index.html" file contains:

Here is the facebook error message

getElementById().value gives blank for a text box

I am trying to show the value entered in a text box into a javascript alert(). I have a form on whose onSubmit(), I am calling a function checkLogin() in which I am alerting the value entered in the #test_user text box. Below is the HTML code:
<form id="login_form" name="login_form" method="post" action="verifylogin.php" onSubmit="checkLogin()">
<input type="text" id="test_user" name="username" class="inputbox" placeholder="Username" value=""/>
<input type="password" id="password" name="password" class="inputbox" placeholder="Password" />
<input type="submit" id="login" name="submit" value="LOG IN">
Login with facebook
</form>
And below is the checkLogin() function in js:
function checkLogin() {
var uname = document.getElementById('test_user').value;
alert(uname);
}
I need to show the text entered in the text box with id #test_user in the alert but the alert does not show anything. A blank alert is displayed.
I know this can also be done by passing the value as a parameter to the function but I wanted to know why this way isn't working.
Please help.
UPDATE: It does work when I use this code separately but when I am doing this in a website I am developing, this issue arises. I am not able to understand why this is happening.
UPDATE: Below is all my HTML code:

The function checkLogin() is in the file common_functions.js which I have included on line:33 and the login form is at line:129.

try this fiddle, it works for me

as you can see the error was

problem with my drop down login box?

i have a simple Jquery script which allow me to place a nice drop down login box but i have a simple issue with it
when i tried to place more than 1 box lets say 5 the script totally messed
i believe its something regarding the DIV id's and duplication but i don't find a way to resolve this problem
JS code
// Login Form
$(function() {
var button = $('#loginButton');
var box = $('#loginBox');
var form = $('#loginForm');
button.removeAttr('href');
button.mouseup(function(login) {
box.toggle();
button.toggleClass('active');
});
form.mouseup(function() {
return false;
});
$(this).mouseup(function(login) {
if(!($(login.target).parent('#loginButton').length > 0)) {
button.removeClass('active');
box.hide();
}
});
});
