Does anyone know how can I resolve the following: I want the form input by the user, to be alerted in a different HTML file.
This is what I wrote so far. It works for the id called 'name', but I dont know why it does not for the 'position'.
"index.html" file:
<script>
function myFunction() {
name = document.getElementById("name").value;
position = document.getElementById("position").value;
window.location.replace("signature.html");
return false;
}
</script>
<form class="formulario" onsubmit="return myFunction()">
Name: <input type="text" name="name" id="name"><br>
Position: <input type="text" name="position" id="position"><br>
<br>
<input type="submit" value="Generate Signature">
</form>
"signature.html" file - notice the alert(name) and the alert(position) => the alert(name) works, but not the alert(position). I want to understand how to fix that please.
<html>
<head>
</head>
<body>
<div class="signature_general">
<div class = "signature_middle">
<div id = "signature_details">
<font size="2px">Regards,</font><br>
<b><font color="#808080" size="3px" id="nameInput">Francisco Jurado</font></b><br>
<font size="2px" id="posInput">Accounting Systems Team Leader</font>
</div>
</div>
</div>
<script>
alert(name);
alert(position);
</script>
</body>
</html>
Thanks very much
Edit: I have noticed that I am getting an error, in which "position" is "undefined". Does anyone knows?
You can change your html file as:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<form class="formulario" action="signature.html" method="get">
Name: <input type="text" name="name" id="name"><br>
Position: <input type="text" name="position" id="position"><br>
<br>
<input type="submit" value="Generate Signature">
</form>
</body>
</html>
And your signature.html file as :
<html>
<head>
</head>
<body>
<div class="signature_general">
<div class = "signature_middle">
<div id = "signature_details">
<font size="2px">Regards,</font><br>
<b><font color="#808080" size="3px" id="nameInput">Francisco Jurado</font></b><br>
<font size="2px" id="posInput">Accounting Systems Team Leader</font>
</div>
</div>
</div>
<script>
var values = window.location.search.substring(1).split('&')
var name = values[0].split('=')[1]
var position = values[1].split('=')[1]
alert(name)
alert(position)
</script>
</body>
</html>
That name you are setting in index.html is not the same name you are printing in the alert of signature.html.
You can see this by renaming name to name2 in both places.
If you want to pass those variables from one page to another, I suggest using query strings how to exchange variables between two HTML pages?

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!
I'm trying to alert the values of the form elements but this isn't functioning even at its simplest: getting the elements of the form then alerting a string.
The alert fires when it's by itself, but not when I put the form's data in the variable. Why?
I'm sure there's probably a very simple mistake in here somewhere, but I'm stumped.
<!DOCTYPE html>
<html>
<head>
<!-- ISTE240 Exercise 5b -->
<meta charset=utf-8 />
<title>Get elements from a form</title>
<script>
function getFormValues() {
// function to send first and last names to an 'alert' message.
alert("test");
var form = document.getElementById(“regForm”).elements;
}
</script>
</head>
<body>
<p>JavaScript Exercise 5b </p>
<form id="regForm" onsubmit="getFormValues()">
First name: <input type="text" name="fname" value="Boo"><br>
Last name: <input type="text" name="lname" value="Radley"><br>
<input type="submit" value="Submit">
</form>
</body>
</html>
By default form tag will try to submit form values. You must prevent default behavior, demo below
document.querySelector('#regForm').onsubmit = function(e){
e.preventDefault();
alert('a');
var form = document.getElementById("regForm").elements; //<-- wrong syntax, must be "
console.log(form);
}

Quick question. I am starting learn on local storage HTML5. How can I get value from a form and display that value on another HTML form page?
For example, I have two forms here.
If I fill on form 1 and click submit button, and the value will display on form 2 in readable only.
I tried below:
HTML Form 1:
<html>
<head>
<title>Save Value</title>
<script type="text/javascript">
function saveVal() {
var inputFirst = document.getElementById("name").value;
localStorage.setItem("name", inputFirst);
inputFirst = localStorage.getItem("name");
}
</script>
</head>
<body>
<form action="display.html" method="get">
<label>
First Name:
<input name="name" size="20" maxlength="25" type="text" id="name" />
</label>
<input type="submit" value="submit" onclick="saveVal()"/>
</form>
</body>
</html>
HTML Form 2:
<html>
<head>
<title>Display</title>
<script type="text/javascript">
function result() {
var storedVal = document.getElementById("name");
storedVal.value = localStorage.getItem("name");
}
</script>
</head>
<body>
<form action="#">
<label>
First Name:
<input name="name" size="20" maxlength="25" type="text" id="name" readonly="readonly" />
</label>
</form>
</body>
</html>
In display.html you didn't call function result(),
try this,
<html>
<head>
<title>Display</title>
</head>
<body>
<form action="#">
<label>
First Name:
<input name="name" size="20" maxlength="25" type="text" id="name" readonly="readonly" />
</label>
<script type="text/javascript">
var storedVal = document.getElementById("name");
storedVal.value = localStorage.getItem("name");
</script>
</form>
</body>
</html>
I want to insert a basic form into my website so my users can search for recipes. I'm having a hard time getting the javascript to find the input value from the form. Any help would be appreciated.
<!DOCTYPE html>
<html>
<head>
<script>
function searchURL()
{
var foodSearch = window.open("http://search.myrecipes.com/search.html?N=17&mFil=false&Ntt=" + "document.getElementById("searchFood").value");
};
</script>
</head>
<body>
<form>
<fieldset>
<legend>Search for Healthy Diet Recipes</legend>
<p>
Type in the name of the Recipe or Healthy Diet Food you would like to cook below:<br>
</p>
<br>
<input type="text" id='searchFood' >
<input type="button" value="Find Delicious Food" onClick="searchURL()">
</fieldset>
</form>
</body>
</html>
Do not add it into "" quotes.
Use this:
var foodSearch = window.open("http://search.myrecipes.com/search.html?N=17&mFil=false&Ntt=" + document.getElementById("searchFood").value);
I'm new to Javascript. Can I show direct data from an HTML form on the same page. My code is here:
<html>
<head>
<title></title>
</head>
<script>
document.getElementById("btn").onclick = avc;
function avc(){
var a = document.getElementsByName("firstname").value;
document.getElementsByName("abc").innerHTML = a;
}
</script>
<body>
<form method="post">
First name: <input id="fname" type="text" name="firstname"><br>
<input id="btn" type="submit">
</form>
<div name="abc"></div>
</body>
</html>
Using the ID for the element would also work when getting the value.
var a = document.getElementById('fname').value;
Yes you can with
<script>
document.getElementById('abc').innerHTML=document.getElementById('fname').value;
</script>
at the end
if you want that every time you write something in text box changes the value in div abc try this:
<html>
<head></head>
<body>
<form method="post">
First name: <input id="fname" type="text" name="firstname" onKeyUp="f()"><br>
<input id="btn" type="submit">
</form>
<div id="abc"></div>
<script>
function f() {
document.getElementById('abc').innerHTML=document.getElementById('fname').value;
}
f(document.getElementById('fname').value);
</script>
</body>
</html>
Yes, but you need to subscript the correct element like so...
var a = document.getElementsByName("firstname")[0].value;
