I haven't done front end HTML since I was 10 and that was drag and drop frontpage stuff. with static pages. As a result I'm really rusty.
What I need to do is put together a web client for a rest API that I wrote in NodeJS. My question is how, do you send a request from a form (say a log in form) to the server where the body of the POST request is a JSON of the email/password?
HTML form:
<form id="loginForm" action="" method="" class="form-horizontal">
<fieldset>
<legend>Log in</legend>
<div class="control-group">
<label class="control-label" for="email">Email</label>
<div class="controls">
<input type="text" class="input-xlarge" id="email">
</div>
</div>
<div class="control-group">
<label class="control-label" for="password">Password</label>
<div class="controls">
<input type="password" class="input-xlarge" id="password">
</div>
</div>
<div class="form-actions">
<button type="submit" class="btn btn-primary">Save changes</button>
<button class="btn">Cancel</button>
</div>
</fieldset>
</form>
I suggest a lot of reading. To get you started with a very basic example, though, you will find a page with a sample form below that does what you need. You just need to replace the string your URL here with the actual URL you expect will be doing the handling.
The serializeObject() function was taken from here: Convert form data to JavaScript object with jQuery
<html>
<body>
<form id="loginForm" action="" method="">
Username: <input type="text" name="username" id="username" /> <br />
Password: <input type="password" name="password" id="password" /> <br />
<input type="submit" />
</form>
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
<script type="text/javascript">
$(function () {
$.fn.serializeObject = function()
{
var o = {};
var a = this.serializeArray();
$.each(a, function() {
if (o[this.name] !== undefined) {
if (!o[this.name].push) {
o[this.name] = [o[this.name]];
}
o[this.name].push(this.value || '');
} else {
o[this.name] = this.value || '';
}
});
return o;
};
$("#loginForm").bind("submit", function(evt) {
console.log(JSON.stringify($("#loginForm").serializeObject()));
$.ajax({
url: "your URL here",
type: "POST",
contentType: "application/json",
data: JSON.stringify($("#loginForm").serializeObject()),
success: function (data, textStatus, jqXHR) {
// do something with your data here.
},
error: function (jqXHR, textStatus, errorThrown) {
// likewise do something with your error here.
}
});
return false;
});
});
</script>
</body>
</html>
The problem with your form is that input elements don't have name attributes. The name attribute is essential in many ways, so I would fix your html by setting each element's name attribute to the same value as its id attribute. The serializeObject function relies on form elements having names.
Here's an example using jQuery:
<form name="myform" action="#" method="POST">
Username: <input type="text" id="user" name="username"/><br/>
Password: <input type="password" id="pass" name="password"/>
<input type="submit" id="login" value="Login"/>
</form>
<script type="text/javascript">
var user=$('#user').val(), pass=$('#pass').val();
$('login').bind('click', function() {
$.ajax('/my/url', {
type: 'POST',
contentType: 'text/json',
data: JSON.stringify({username:user, password:pass}),
complete: function() { /* Do something with the response. */ }
});
return false; // Prevent form submit.
});
</script>
This might help you. Here is the form below: If you notice there is action and method if you don't know what these are, just go on and search for it. Action is the target server file that handles the information you send and method is get which is retrieving not updating.
Existing Users Username: Password:
Keep Me
Logged In
Here is the jquery part to handle the ajax call:
$.ajax({
type: "GET",
url: action,
data: form_data,
success: function(response)
{
if($.trim(response) == 'success')
window.location.replace("profile.php");
else
$("#result").html(response);
}
});
return false; });
});

How do I prevent the form from checking the required field when I select the "Average Household Income" button.
<form method="post"> The
<input type="text" name="myIncome[0][Income]" required
placeholder="#######.##" pattern="^(?=.*[1-9])\d*(?:\.\d{2}$)?" />
<input type="submit" name='cmdSubmit' value="Submit"
formaction="ProjectCensus.php">
<input type="submit" name='cmdAvgHousehold' value="Average Household Income"
formaction="Average_household.php">
You would want to change the type on that button.
Try:
<button type="button" ... ></button>
Updated as per request:
I recommend you use JQuery ajax() for handling the submitting of the form (it will be the easiest to understand).
$("#myForm").submit(ev => {
ev.preventDefault();
$.ajax({
type: 'POST',
url: "Average_household.php",
// data: {},
success: resp => {
alert("Submitted comment");
},
error: resp => {
alert("There was an error submitting this form");
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<!-- src: https://html.com/attributes/button-type/ -->
<form id="myForm" action="/button-type">
<button type="button" onclick="alert('This button does nothing.')">Click me for no reason!</button>
<br><br>
<label for="name">Name</label><br>
<input name="name"><br><br> <button type="reset">Reset the form!</button><br><br>
<button type="submit" disabled>Submit (disabled)</button>
</form>
Hope this helps,
How can I display the form submitted data in another HTML Page
From 1st page (page1.html)collecting the data from users and after appending this data in the database I want to show the submitted values in another page i.e.(page4.html)
Below is my code
I have tried using res.sendFile or res.send
server.post('/addname', (req, res) => {
const user = {
timestamp: new Date,
FName: req.body.FName,
LName: req.body.LName,
Phone: req.body.Phone,
Email: req.body.email,
Contact: req.body.business,
Business: req.body.contact,
OTP: req.body.otp_field
}
res.sendFile(__dirname + '/page4.html');
//along with file rediraction, how can i send or show the "User" vaules in respactivte filed
});
<body>
<div>
<div align="center">
<form action="/addname" method="GET">
<label>Please enter below details</label><br><br>
<label>First Name *: </label><input id="FName" type="text" name="FName"/><br><br>
<label>Last Name *: </label><input id="LName" type="text" name="LName"/><br><br>
<label>Email Address *: </label><input type="email" name="email"><br><br>
<br><br>
<input type="submit" value="Submit" /></form>
</div>
</div>
</body>
nAs I can see in your code
<body>
<div>
<div align="center">
<form action="/addname" method="GET">
<label>Please enter below details</label><br><br>
<label>First Name *: </label><input id="FName" type="text" name="FName"/><br><br>
<label>Last Name *: </label><input id="LName" type="text" name="LName"/><br><br>
<label>Email Address *: </label><input type="email" name="email"><br><br>
<br><br>
<input type="submit" value="Submit" /></form>
</div>
</div>
</body>
Your form method is "GET", it should be "POST" as your API is "POST".
server.post('/addname', (req, res) => {
<form action="/addname" method="GET">
//Just change to
<form action="/addname" method="POST">
While sending and HTML file you need to send your submitted data too.
res.sendFile(__dirname + '/page4.html');
In order to save your hurdle switch to Single Page Application and use some JavaScript frame work like AngularJs, ReactJs or if not then also stick to single page and use Ajax calls for submit calls.
Else see "ejs" in place of "HTML" and use scriptlet to send and show data over HTML.
To send data to "ejs" via expressJs
res.render('show.ejs', {message});
With Ajax you can do this:
HTML
<body>
<div>
<div align="center">
<form id="form1">
<label>Please enter below details</label><br><br>
<label>First Name *: </label><input id="FName" type="text" name="FName"/><br><br>
<label>Last Name *: </label><input id="LName" type="text" name="LName"/><br><br>
<label>Email Address *: </label><input type="email" name="email"><br><br>
<br><br>
<input type="button" value="Submit" onClick:"submitForm()"/>
</form>
<div id="showValue"></div>
</div>
</div>
</body>
JavaScript
function submitForm() {
$.ajax({
url: '/addName',
type: 'POST',
headers: headers,
data: {
"Fname": $("#FName").val(),
"Lname": $("#LName").val(),
"email": $("#email").val()
},
success: function(result) {
//append result to your html
//Dynamic view
$("#form1").hide();
var html = '<div><span>First Name: ' + result.fName + '</span><span>Last Name: ' + result.lName + '</span></div>';
$("#showValue").html(html);
},
error: function (error) {
alert('error ',error);
}
});
}
Server side code I'm assuming you are using express.js and body-parser
app.post('/addName', (req, res) => {
//Insert into db
var body = req.body;
res.send({
fName: body.FName,
lName: body.LName
});
});
I'm fairly new to coding in HTML. After hours of searching the internet for a way to do this, I failed and so I'm here. I was setting up a CSRF Proof of concept page here, I want it to redirect to another page which will execute the payload that the CSRF had implemented.
<html>
<body>
<form action="https://website.com/action.php?" method="POST">
<input type="hidden" name="fullname" value="john" />
<input type="hidden" name="address" value="street 2, 32 ave" />
<input type="submit" value="Submit request" />
</form>
</body>
</html>
So after this form is submitted using, all it does is redirect to this page
But instead of that, I want it to redirect to another URL as well as submit that form.
For anyone else having the same problem, I figured it out myself.
<html>
<body>
<form target="_blank" action="https://website.com/action.php" method="POST">
<input type="hidden" name="fullname" value="Sam" />
<input type="hidden" name="city" value="Dubai " />
<input onclick="window.location.href = 'https://website.com/my-account';" type="submit" value="Submit request" />
</form>
</body>
</html>
All I had to do was add the target="_blank" attribute to inline on form to open the response in a new page and redirect the other page using onclick on the submit button.
You need to use the jQuery AJAX or XMLHttpRequest() for post the data to the server. After data posting you can redirect your page to another page by window.location.href.
Example:
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
window.location.href = 'https://website.com/my-account';
}
};
xhttp.open("POST", "demo_post.asp", true);
xhttp.send();
in case you are generating the form programmatically you can add this script at the end of the form
<script type="text/javascript">document.forms["FormId"].submit();</script>
What you could do is, a validation of the values, for example:
if the value of the input of fullanme is greater than some value length and if the value of the input of address is greater than some value length then redirect to a new page, otherwise shows an error for the input.
// We access to the inputs by their id's
let fullname = document.getElementById("fullname");
let address = document.getElementById("address");
// Error messages
let errorElement = document.getElementById("name_error");
let errorElementAddress = document.getElementById("address_error");
// Form
let contactForm = document.getElementById("form");
// Event listener
contactForm.addEventListener("submit", function (e) {
let messageName = [];
let messageAddress = [];
if (fullname.value === "" || fullname.value === null) {
messageName.push("* This field is required");
}
if (address.value === "" || address.value === null) {
messageAddress.push("* This field is required");
}
// Statement to shows the errors
if (messageName.length || messageAddress.length > 0) {
e.preventDefault();
errorElement.innerText = messageName;
errorElementAddress.innerText = messageAddress;
}
// if the values length is filled and it's greater than 2 then redirect to this page
if (
(fullname.value.length > 2,
address.value.length > 2)
) {
e.preventDefault();
window.location.assign("https://www.google.com");
}
});
.error {
color: #000;
}
.input-container {
display: flex;
flex-direction: column;
margin: 1rem auto;
}
<html>
<body>
<form id="form" method="POST">
<div class="input-container">
<label>Full name:</label>
<input type="text" id="fullname" name="fullname">
<div class="error" id="name_error"></div>
</div>
<div class="input-container">
<label>Address:</label>
<input type="text" id="address" name="address">
<div class="error" id="address_error"></div>
</div>
<button type="submit" id="submit_button" value="Submit request" >Submit</button>
</form>
</body>
</html>
For me this one worked pretty well.
=> form target to blank (opens in a new tab) + input id to be recognized in Javascript + script that redirects.
<html>
<body>
<form target="_blank" action="https://website.com/action.php" method="POST">
<input type="hidden" name="fullname" value="Sam" />
<input type="hidden" name="city" value="Dubai " />
<input type="submit" value="Submit request" id="submitBtn"/>
<script>
document.getElementById("submitBtn").addEventListener("click", myFunction);
function myFunction() {
window.location.href="http://programminghead.com";
}
</script>
</form>
</body>

I am using this sample form to send data. I currently watch under the console. But I really need to send these information to another page called result.html and I want to know how to do that. Currently I am using the following code in the main page... Here is the code

I want to know how should be the code in the result.html page to grab the parameters sent by these forms. Please help me I am really new to angularjs.

I am trying to get an input value with AngularJS from input field to another hidden input field (in another form in the same page) so I can transmit it later if user presses submit on the other form.
<div ng-app="">
<p>Name: <input type="text" ng-model="name"></p>
//down the code...
<form name="whatever" method="post">
<input type="hidden" ng-bind="name" value="">
</form>
</div>
When I inspect the code after I put data in the visible input field all looks fine - so when I change the data inside the visible input I can see it in the hidden input too but I can't see it in the POST variable after I submit the form - I guess it's because it doesn't change the value field in the hidden input just what between the and .
How can I get this to work so that I change the value of an hidden input - but not what between the opening and closing input field?
Just Replace ng-bind with ng-value like:
<input type="hidden" ng-value="name">

I see you answered yourself already. Anyway you should go for more "angular way" when handling your forms, letting angular do the "posting". For example:
HTML template
<body ng-controller="MainCtrl">
<form name="form1"
ng-submit="submit()">
Name: <input type="text"
class="form-control"
name="name"
ng-model="user.name"
required>
<div class="alert alert-warning"
ng-show="form1.name.$error.required">
Required field
</div>
<input type="submit"
class="btn btn-primary"
value="submit">
</form>
<div class="alert"
ng-class="{ 'alert-success': response.status === 200, 'alert-danger': response.status !== 200 }"
ng-show="response !== null">
DATA: {{ response.data }}<br>
HTTP {{ response.status }} {{ response.statusText }}
</div>
<hr>
<form name="form2" ng-submit="submit()">
Name: <input type="text"
class="form-control"
ng-model="user.name">
Age: <input type="number"
class="form-control"
min="1"
max="100"
ng-model="user.age">
<input type="submit"
class="btn btn-primary"
value="submit" disabled>
</form>
</body>
JavaScript
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope, $http) {
$scope.user = {};
$scope.response = null;
$scope.submit = function() {
$scope.response = null;
$http({
method: 'POST',
url: 'http://jsonplaceholder.typifcode.com/posts',
data: $scope.user,
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
}).then(function (response) {
$scope.response = response;
}).catch(function (response) {
$scope.response = response;
});
};
});
You'll get something like
