This is the original script http://www.javascriptkit.com/script/script2/loginpass2.shtml
thanx in advance
Because you are using an external script, i can't really find where you store the ID.
add the following somewhere in your code where you want to show the staff name:
<div class="staff-name-placeholder">Enter ID</div>
modify input:
<p>Staff ID <input type="text" name="username"> </p>
To:
<p>Staff ID <input type="text" name="username" onchange="updatestaff();"> </p>
add following on the bottom of the page:
<script type="text/javascript">
function updatestaff()
{
document.getElementById('staff-name-placeholder').innerHTML='[PLACE ID]';
}
</script>
It does the following:
binds a listener when the input 'username' is changed.
searches the element with id 'staff-name-placeholder'
replaces the HTML inside the element with '[PLACE ID]'.
Of course, the real id isn't given yet, you must pass it through your other script.
I hope this helps a little bit.

I am a high school student and I am trying to make a password cracker to show my school how vulnerable their Student Dashboard is. A student Dashboard is a website that contains student accounts, links, and private information like addresses, passwords, and relatives.
Everyone's password has the following syntax: Pmonth/day/year
EXAMPLE: P05/03/2005
There is a problem though, when the code clicks the sign in button, the URL changes, and the page reloads, which stops the code when I run it in the console.
Is there a way that I could keep the code running from console even if page reloads.
I have thought of using web cookies to store the last used password, and then when the page reloads, just input it into the password textbox, but I am not sure, since I haven't used cookies before.
Any help is greatly appreciated.
What I am aiming to do is that I input an Id, and then it tries to crack the password by going through all dates a year has after 2003.
I will appreciate all answers, but I would like my answer in raw javascript(no libraries).
The sign in page consists of an username textbox, a password textbox and a sign in button.
Here's what the sign in page looks like: Sign in page

Your challenge is to persist your JavaScript code inside a website hosted by someone else. All code within your browsers console is obsolete after page reload.
Another challenge you are facing is a legal one. It's highly recommended to get a permission to access an online service for the purpose you described. Any kind of security assessment has to be coordinated and aligned with the organization responsible for the questioned online service.
Since you will not want to change the content of the web server for legal reasons, you would need a tool manipulate the content served by the webserver within your client (read "browser").
There are browser automation tool like Puppeteer or Selenium Webdriver you can use to request any url repeatedly and to automate certain actions within the context of a browser like clicking elements, filling forms, executing JavaScript and so on.
Additionally there a fuzzers that can perform what is called credential stuffing. You can read more here about Burp Suite.

In the above code I would like to redirect the page with the help of Javascript, but window.location = 'dws_Support.php' in else part is not working, but when we alert with in the else part it gets displayed but not redirected to 'dws_Support.php'. Please help.
Try using
window.location.href='dws_Support.php'
you don't need form for redirecting with javascript ,problem come from your attribute action form, so use this code:
<script src="js/jquery.js"></script>
<script>
$(document).ready(function() {
$("#submit").click(function() {
var value = document.getElementById("txt_sketch_no").value;
var process_id = document.getElementById("process_id").value;
var length = value.length;
if (length <= 0) {
alert("Please Enter the sketch card");
window.location = 'sketch_screen.php';

window.location = 'dws_Support.php';
}
});

<input type="text" id="txt_sketch_no" name="txt_sketch_no">
<input type = "submit" id="submit">
</div>
</div>
</body>
hope it help you.
Here is your fail: you are listening click, but submit event of the form brakes your logic. This is the fixed one:
$(document).ready(function() {
$("form").on('submit', function(e) {
e.preventDefault();
var value = document.getElementById("txt_sketch_no").value;
var process_id = document.getElementById("process_id").value;
var length = value.length;
if (length <= 0) {
alert("Please Enter the sketch card");
window.location = 'sketch_screen.php';
} else {
window.location = 'dws_Support.php';
}
});
});
glad if you found the answer, but there is no problem with your coding, you just missed the return false; after redirect..

hope this can fix your problem. :)
i am new to JavaScript and this site and am trying to make a username and password creator and log in. for now i am just using a premade username and password for now. i have tried to do this with JavaScript but my code wont work for me on notepad++. i have learned a basic understanding of jQuery as a last resort to get this mock up site to run. can you tell me if there is a way to do it with JavaScript and how and if not can you explain the code to share variables across two different webpages using jQuery. pleas explain in plain simple English because as i said i am new to JavaScript and brand new to jQuery.
here is where the username and password variables are defined.
<!DOCTYPE html>
<html>
<head>
<title>
create account
</title>
<script>
sessionStorage.setItem( "username1", ["bob", "sam"]);
sessionStorage.setItem( "password1", ["lol", "jk"]);
</script>
</head>
<body>
</body>
</html>
here is where i call those variables
<!DOCTYPE html>
<html>
<head>
<title>
log on page
</title>
<script type = "text/javascript">
var count = 2;
function validate() {
var un = document.myform.username.value;
var pw = document.myform.pword.value;
var valid = false;
var unArray = sessionStorage.getItem("username1");
var unArray = sessionStorage.getItem("password1");
for (var i=0; i <unArray.length; i++) {
if ((un == unArray[i]) && (pw == pwArray[i])) {
valid = true;
break;
}
}
if (valid) {
alert ("Login was successful");
window.location = "http://www.google.com";
return false;
}
var t = " tries";
if (count == 1) {t = " try"}
if (count >= 1) {
alert ("Invalid username and/or password. " +
"You have " + count + t + " left.");
document.myform.username.value = "";
document.myform.pword.value = "";
setTimeout("document.myform.username.focus()", 25);
setTimeout("document.myform.username.select()", 25);
count --;
}
else {
alert ("Still incorrect! You have no more tries left!");
document.myform.username.value = "No more tries allowed!";
document.myform.pword.value = "";
document.myform.username.disabled = true;
document.myform.pword.disabled = true;
return false;
}
}
</script>

I want my form submit button to be disabled/enabled depending on if the form is completely filled.
When the inputs are filled, the disabled button changes to enabled. That works great.
But I would like it to disable the button when an input gets emtied.
This is my script:
<script type="text/javascript" language="javascript">
function checkform()
{
var f = document.forms["theform"].elements;
var cansubmit = true;
for (var i = 0; i < f.length; i++) {
if (f[i].value.length == 0) cansubmit = false;
}
if (cansubmit) {
document.getElementById('submitbutton').disabled = false;
}
}
</script>
<form name="theform">
<input type="text" onKeyup="checkform()" />
<input type="text" onKeyup="checkform()" />
<input id="submitbutton" type="submit" disabled="disabled" value="Submit" />
</form>
Just use
document.getElementById('submitbutton').disabled = !cansubmit;
instead of the the if-clause that works only one-way.
Also, for the users who have JS disabled, I'd suggest to set the initial disabled by JS only. To do so, just move the script behind the <form> and call checkform(); once.
Just add an else then:
function checkform()
{
var f = document.forms["theform"].elements;
var cansubmit = true;
for (var i = 0; i < f.length; i++) {
if (f[i].value.length == 0) cansubmit = false;
}
if (cansubmit) {
document.getElementById('submitbutton').disabled = false;
}
else {
document.getElementById('submitbutton').disabled = 'disabled';
}
}
Put it inside a table and then do on her:
var tabPom = document.getElementById("tabPomId");
$(tabPom ).prop('disabled', true/false);
I just posted this on Disable Submit button until Input fields filled in. Works for me.
Use the form onsubmit. Nice and clean. You don't have to worry about the change and keypress events firing. Don't have to worry about keyup and focus issues.
http://www.w3schools.com/jsref/event_form_onsubmit.asp
<form action="formpost.php" method="POST" onsubmit="return validateCreditCardForm()">
...
</form>
function validateCreditCardForm(){
var result = false;
if (($('#billing-cc-exp').val().length > 0) &&
($('#billing-cvv').val().length > 0) &&
($('#billing-cc-number').val().length > 0)) {
result = true;
}
return result;
}
Here is the code
<html>
<body>
<input type="text" name="name" id="name" required="required" aria-required="true" pattern="[a-z]{1,5}" onchange="func()">
<script>
function func()
{
var namdata=document.form1.name.value;
if(namdata.match("[a-z]{1,5}"))
{
document.getElementById("but1").disabled=false;
}
}
</script>
</body>
</html>
Using Javascript
I think this will be much simpler for beginners in JavaScript
//The function checks if the password and confirm password match
// Then disables the submit button for mismatch but enables if they match
function checkPass()
{
//Store the password field objects into variables ...
var pass1 = document.getElementById("register-password");
var pass2 = document.getElementById("confirm-password");
//Store the Confimation Message Object ...
var message = document.getElementById('confirmMessage');
//Set the colors we will be using ...
var goodColor = "#66cc66";
var badColor = "#ff6666";
//Compare the values in the password field
//and the confirmation field
if(pass1.value == pass2.value){
//The passwords match.
//Set the color to the good color and inform
//the user that they have entered the correct password
pass2.style.backgroundColor = goodColor;
message.style.color = goodColor;
message.innerHTML = "Passwords Match!"
//Enables the submit button when there's no mismatch
var tabPom = document.getElementById("btnSignUp");
$(tabPom ).prop('disabled', false);
}else{
//The passwords do not match.
//Set the color to the bad color and
//notify the user.
pass2.style.backgroundColor = badColor;
message.style.color = badColor;
message.innerHTML = "Passwords Do Not Match!"
//Disables the submit button when there's mismatch
var tabPom = document.getElementById("btnSignUp");
$(tabPom ).prop('disabled', true);
}
}
<form name="theform">
<input type="text" />
<input type="text" />`enter code here`
<input id="submitbutton" type="submit"disabled="disabled" value="Submit"/>
</form>
<script type="text/javascript" language="javascript">
let txt = document.querySelectorAll('[type="text"]');
for (let i = 0; i < txt.length; i++) {
txt[i].oninput = () => {
if (!(txt[0].value == '') && !(txt[1].value == '')) {
submitbutton.removeAttribute('disabled')
}
}
}
</script>
Here is my way of validating a form with a disabled button. Check out the snippet below:
var inp = document.getElementsByTagName("input");
var btn = document.getElementById("btn");
// Disable the button dynamically using javascript
btn.disabled = "disabled";
function checkForm() {
for (var i = 0; i < inp.length; i++) {
if (inp[i].checkValidity() == false) {
btn.disabled = "disabled";
} else {
btn.disabled = false;
}
}
}

<h1>Javascript form validation</h1>
<p>Javascript constraint form validation example:</p>
<form onkeyup="checkForm()" autocomplete="off" novalidate>
<input type="text" name="fname" placeholder="First Name" required><br><br>
<input type="text" name="lname" placeholder="Last Name" required><br><br>
<button type="submit" id="btn">Submit</button>
</form>
</body>
</html>
Example explained:
We create a variable to store all the input elements.
var inp = document.getElementsByTagName("input");
We create another variable to store the button element
var btn = document.getElementById("btn");
We loop over the collection of input elements
for (var i = 0; i < inp.length; i++) {
// Code
}
Finally, We use the checkValidity() method to check if the input elements
(with a required attribute) are valid or not (Code is inserted inside the
for loop). If it is invalid, then the button will remain disabled, else the
attribute is removed.
for (var i = 0; i < inp.length; i++) {
if (inp[i].checkValidity() == false) {
btn.disabled = "disabled";
} else {
btn.disabled = false;
}
}
You can enable and disable the submit button based on the javascript validation below is the validation code.
<script>
function validate() {
var valid = true;
valid = checkEmpty($("#name"));
valid = valid && checkEmail($("#email"));
$("#san-button").attr("disabled",true);
if(valid) {
$("#san-button").attr("disabled",false);
}
}
function checkEmpty(obj) {
var name = $(obj).attr("name");
$("."+name+"-validation").html("");
$(obj).css("border","");
if($(obj).val() == "") {
$(obj).css("border","#FF0000 1px solid");
$("."+name+"-validation").html("Required");
return false;
}
return true;
}
function checkEmail(obj) {
var result = true;
var name = $(obj).attr("name");
$("."+name+"-validation").html("");
$(obj).css("border","");
result = checkEmpty(obj);
if(!result) {
$(obj).css("border","#FF0000 1px solid");
$("."+name+"-validation").html("Required");
return false;
}
var email_regex = /^([a-zA-Z0-9_.+-])+\#(([a-zA-Z0-9-])+\.)+([a-zA-Z0-9]{2,3})+$/;
result = email_regex.test($(obj).val());
if(!result) {
$(obj).css("border","#FF0000 1px solid");
$("."+name+"-validation").html("Invalid");
return false;
}
return result;
}
</script>
first time on the website, anyway my problem is that when I use onkeydown and then use GetChar to check if the enter key was pressed, when operAtion runs,the results of the function only shows on the screen for about a second and then goes away, if the user uses the onclick (clicks the enter button), then this problem doesnt occur. How do I get the result of operAtion to stay on the screen when onkeydown is used. The website is sqrtcalc.comze.com if you want to see what I mean

document.getElementById("demo").innerHTML = "";
} else if (x < 0){
var y = "Number must be positive";
document.getElementById("failsafe").innerHTML = y;
document.getElementById("demo").innerHTML = "";
} else if (x == ""){
var y = "uhm, you didnt enter anything";

document.getElementById("demo").innerHTML = "The square root of " + x + " is " + y;

Add this code:
window.onload = function(){
document.getElementById("myform").onsubmit = function(){
return false;
}
}
And add the id attribute id="myform" to the <form> tag.
I refactored your code a little:
I removed your inline functions (inline JS isn't exactly best
practice)
I added an ID to your form so it could be referenced
I added return false; to keep the form from submitting
onsubmit handles both click and enter
Javascript
document.getElementById('myform').onsubmit = function() {
var x = this.inputbox.value;
if (isNaN(x)) {
//document.write("lawl");
var y = "Enter a number";
document.getElementById("failsafe").innerHTML = y;
document.getElementById("demo").innerHTML = "";
} else if (x < 0) {
var y = "Number must be positive";
document.getElementById("failsafe").innerHTML = y;
document.getElementById("demo").innerHTML = "";
} else if (x == "") {
var y = "uhm, you didnt enter anything";
document.getElementById("failsafe").innerHTML = y;
document.getElementById("demo").innerHTML = "";
} else {
var y = Math.pow(x, 1 / 2)
document.getElementById("demo").innerHTML = "The square root of " + x + " is " + y;
document.getElementById("failsafe").innerHTML = "";
}
return false;
}
