So, I have the HTML & CSS code already, but I need to make it so when you click button, it checks the contents of the input boxes and if equal to
Username = damon
Password = password
it lets you redirects to chat.html and if its wrong it does alert("wrong").
(I dont know JavaScript so I'm asking here.)
<html>
<head>
<title>Login</title>
<link rel="stylesheet" href="style/main.css">
</head>
<body>
<div id="content">
<div class="login">
<h1>Login</h1>
<input placeholder="username" type="text" >
<input placeholder="password" type="password" id="password">
<button type="button" onclick="" id="enter">ENTER</button>
</div>
</div>
</body>
<script src="script/db.js"></script>
<script src="script/main.js"></script>
</html>
db.js is empty and main.js has
function clickHandler() {
if (username === 'damon' && password === 'poop'){
window.location.replace("chat.html");
} else {
alert('Wrong!')
}
}
Hardcoding or doing user login checks on client side is not recommended as anyone can read the source and find out your login credentials.
But just assume that you just wanted to learn and try it out. You may do it like this.
Inline Onclick Function Call:
//this is main.js
function clickHandler() {
if (document.getElementById("username").value === "damon" && document.getElementById("password").value === 'poop'){
console.log("redirect to chat.html");
//window.location.replace("chat.html");
} else {
alert('Wrong!');
}
}
<html>
<head>
<title>Login</title>
<link rel="stylesheet" href="style/main.css">
</head>
<body>
<div id="content">
<div class="login">
<h1>Login</h1>
<!--Added id="username" to below input-->
<input placeholder="username" id="username" type="text" >
<input placeholder="password" id="password" type="password">
<!--You may use inline onclick to call clickHandler function-->
<button type="button" onclick="clickHandler()" id="enter">ENTER</button>
</div>
</div>
</body>
<script src="script/db.js"></script>
<script src="script/main.js"></script>
</html>
Or you may do it by attaching onclick listener to the button to call function.

I currently create a PHP Login using Joget SSO. The Joget already have its own script of SSO. I follow the steps and if the username and password is matched, it will alert "login sucessfully" else, it will alert "login failed". Below is my code

$(document).ready(function(){
var loginCallback = {

if(response.username != "roleAnonymous"){
alert("login successfully");

}
}
};
AssignmentManager.login('https://workflow.topglove.com:10443/jw/web/json/directory/user/sso', 'admin', 'admin', loginCallback);
});
</script>
loginCallback is an object.You can either make it as a function or use loginCallback.success() inide your onclick.
Also I doubt if the control goes inside document.ready method.You can add a console inside and check if it is declaring loginCallback variable.
Try the below
function loginCallback() {
success : function(response){
if(response.username != "roleAnonymous"){
alert("login successfully");
}else{
alert("login fail");
}
}
};
AssignmentManager.login('https://workflow.topglove.com:10443/jw/web/json/directory/user/sso', 'admin', 'admin', loginCallback());
basically i have a form which inside that form i have a textbox and a submit button, now what i want is to output text box value into console when a user type something, i found this link https://codepen.io/jnnkm/pen/WxWqwX?editors=1111 which works just perfect but when i copied the html and script code and putted it my editor and ran it trough my browser, it doesn't works at all,
here is how i tried it out:
<!DOCTYPE HTML>
<html>
<head>
<script src="JquerySock.js"></script>
<script>
function postUsernameToServer() {
console.log('executed function')
var username = $("#Registeration_Username_box").val();
console.log(username);
}
$('#Registeration_Username_box').on('input', function() {
console.log('excuted input');
postUsernameToServer();
});
</script>
</head>
<body>
<div id="Registeration_Div" class="Registeration_Div">
<form class="Registration_Form" id="Registration_Form" action="../postr" method="POST">
<div id="Registeration_Username_DIV" class="Registeration_Username_DIV">
<input type="text" id="Registeration_Username_box" class="Registeration_Username_box" placeholder="" name="UserName" maxlength="30" />
</div>
<div class="Registration_Submit_Div">
<input type="submit" value="Submit" id="SumbitForm_btn" class="SumbitForm_btn" name="Submit_btn" />
</div>
</form>
</div>
</body>
</html>
you can try it yourself too, but it didn't worked for me.
okay i found what the problem was, first i had to specify
$(document).ready(function() {
and then input my ajax code, i mean fully it was suppose to be this way
<!DOCTYPE HTML>
<html>
<head>
<script src="JquerySock.js"></script>
<script>
function postUsernameToServer() {
console.log('executed function')
var username = $("#Registeration_Username_box").val();
console.log(username);
}
$(document).ready(function() {
$('#Registeration_Username_box').on('input', function() {
console.log('excuted input');
postUsernameToServer();
});
});
</script>
</head>
<body>
<div id="Registeration_Div" class="Registeration_Div">
<form class="Registration_Form" id="Registration_Form" action="../postr" method="POST">
<div id="Registeration_Username_DIV" class="Registeration_Username_DIV">
<input type="text" id="Registeration_Username_box" class="Registeration_Username_box" placeholder="" name="UserName" maxlength="30" />
</div>
<div class="Registration_Submit_Div">
<input type="submit" value="Submit" id="SumbitForm_btn" class="SumbitForm_btn" name="Submit_btn" />
</div>
</form>
</div>
</body>
</html>
now it works perfect!

app.controller("loginCtrl", function($scope){
$scope.username = "";
$scope.password = "";
$scope.submitForm=function(){
};
});
</script>
</body>
</html>
Now I have a login page as it shows above, I'm trying to do the validation with ngMessages
If I have to use <a> which is outside of form to submit it instead of button, how should I do?
How can I make sure error messages are displayed when username or password is empty, and only after user submit the form.
How to prevent user from resubmitting form with <a>?
To show error messages only after form submit, add a variable '$scope.submitted = true;'.
In order to prevent re-submit submit button can be disabled.
Please refer following link for detailed explanation.
https://scotch.io/tutorials/angularjs-form-validation
Hope it helps.
You can check the validation result in your controller function with:
if ($scope.form_login.$valid) {
...
}
The form in angularjs will be validated auto. For all form members you can check the doc
I am creating an app to send an object to a class in Parse, but the data in the form is being passed and nothing happens. I can submit data directly from the function showAlert, but no alert appears after setNotification and and showALert is used. Here is my code:

I am dusting off my Javascript knowledge to create an page that syncs to an iOS app. Any help is greatly appreciated!
I am very new to jquery. Here what I'm trying to do is creating text box and button(login form). The following code is giveing me duplicate result. Is there something wrong with my code?
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.2/jquery.mobile-1.3.2.min.css">
<script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
<script src="http://code.jquery.com/mobile/1.3.2/jquery.mobile-1.3.2.min.js"></script>
</head>
<body>
<script type="text/javascript">
$(document).ready( function () {
$(".start").append('<div data-role="fieldcontain"><label for="username">User Name:</label><input type="text" name="username" id="username"></br><label for="password">Password:</label><input type="password" name="password" id="password"></div><div data-role="content"><input type="submit" value="Sign In"/></div>');
return false;
});
</script>
<br>
<br>
<div class="start">
<label class="control-label" for="inputEmail">Sign In to xRM 360</label>
</div>
<br>
<br>
</body>
</html>
What is happening is the $(document).ready is being called twice. I think this may have to do with jQuery mobile.
See here:
jQuery $(document).ready () fires twice
And here:
http://forum.jquery.com/topic/jquery-jquerymobile-document-ready-called-twice
for more information.
A quick fix is to put the script tag in the head tag. See example below.
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.2/jquery.mobile-1.3.2.min.css">
<script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
<script src="http://code.jquery.com/mobile/1.3.2/jquery.mobile-1.3.2.min.js"></script>
<script type="text/javascript">
$(document).ready( function () {
$(".start").append('<div data-role="fieldcontain"><label for="username">User Name:</label><input type="text" name="username" id="username"></br><label for="password">Password:</label><input type="password" name="password" id="password"></div><div data-role="content"><input type="submit" value="Sign In"/></div>');
return false;
});
</script>

<body>
<br>
