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 pretty new to JavaScript and am creating a simple page to output the form values. But there's seem to be a problem that it is not showing.
<html>
<head>
<title>Return first and last name from a form - w3resource</title>
</head>
<body>
<form id="form1" onsubmit="form()">
First name: <input type="text" name="fname" value="David"><br>
Last name: <input type="text" name="lname" value="Beckham"><br>
<input type="submit" value="Submit">
</form>
<p id="firstname"></p>
<script>
function form() {
var x = document.getElementById("form1").elements[0].value;
document.getElementById("firstname").innerHTML = x;
}
</script>
</body>
</html>
I can't seem to find any problems, the console was fine with the code.
You have to stop the form from submitting.
<html>
<head>
<title>Return first and last name from a form - w3resource</title>
</head>
<body>
<form id="form1" onsubmit="return form()">
First name: <input type="text" name="fname" value="David"><br>
Last name: <input type="text" name="lname" value="Beckham"><br>
<input type="submit" value="Submit">
</form>
<p id="firstname"></p>
<script>
function form() {
var x = document.getElementById("form1").elements[0].value;
document.getElementById("firstname").innerHTML = x;
return false;
}
</script>
</body>
</html>
Use an event listener to handle the submit and preventDefault() for stopping the submission. Following code is tested and working.

<input type="submit" value="Submit">
</form>
<p id="firstname"></p>
<script>
document.getElementById("form1").addEventListener("submit", form);
function form(e) {
e.preventDefault();
var x = document.getElementById("form1").elements[0].value;
document.getElementById("firstname").innerHTML = x;

I have the following HTML page:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>demo</title>
<link rel="stylesheet" href="style.css" />
<script src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
<script src="script.js"></script>
</head>
<body>
<div class="field">
<label for="value1">Introduce value</label>
<input type="text" id="value1" name="value1" value="" />
</div>
<div class="button-block">
<input type="submit" value="Click" />
</div>
<div id="output">
<h2>Result:</h2>
<textarea name="result" id="result"></textarea>
</div>
</body>
</html>
I want to get the value that is introduced in value1 and when the submit is clicked to put that value in the output. So I wrote in script.js the following code but somehow it doesn't work.
<script>
window.onload = function(){
var val = document.getElementById('value1').innerHTML;
document.getElementById('result').innerHTML = val;
};
</script>
Any ideas?
You have to use .value property of the input field instead of innerHTML. so it would be:
var val = document.getElementById('value1').value;
and also, since you're executing it when the page loads. There will be no value assigned to the input field with id 'value1'. Therefore, you won't get any result.
You can try adding a button with onClick event to execute this function in place of using window.onload
HTML controls you are working on are textboxes, so they have a value property, not innerHTML.
Use this:
var val = document.getElementById('value1').value;
document.getElementById('result').value= val;
You can't get the value of an input element using the innerHTML attribute. Use value instead:
var val = documento.getElementById('value1').value;
Also you should keep in mind that your function is executed when the page loads, NOT when the form is submitted.
The code is not working, because you are calling this function when the window loads, not when the submit button is clicked. Since there is no form, and thus no page loading going on, I'd recommend switching the <input type="submit" value="Click" /> to a button. They are functionally similar, and visually identical. With the the button, though you could use the onclick attribute to call a function when the button is clicked. See below for an example
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>demo</title>
<link rel="stylesheet" href="style.css" />
<script src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
<script src="script.js"></script>
</head>
<body>
<div class="field">
<label for="value1">Introduce value</label>
<input type="text" id="value1" name="value1" value="" />
</div>
<div class="button-block">
<button onclick="printOutput()">Click</button>
</div>
<div id="output">
<h2>Result:</h2>
<textarea name="result" id="result"></textarea>
</div>
</body>
</html>
Then in your script.js you would have,
function printOutput(){
var val = document.getElementById('value1').value;
document.getElementById('result').innerHTML = val;
}
when the submit is clicked to put that value in the output
You have chosen wrong event window.onload, also you need .value instead of .innerHTML
Option 1: using jQuery, as you already have the import
$(function() {
$('input[type="submit"]').on('click', function(e) {
$('#result').val($('#value1').val());
});
});
<script src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
<div class="field">
<label for="value1">Introduce value</label>
<input type="text" id="value1" name="value1" value="" />
</div>
<div class="button-block">
<input type="submit" value="Click" />
</div>
<div id="output">
<h2>Result:</h2>
<textarea name="result" id="result"></textarea>
</div>
Option 2: using plain js
document.addEventListener('DOMContentLoaded', function(e) {
document.querySelector('input[type="submit"]').addEventListener('click', function(e) {
document.querySelector('#result').value = document.querySelector('#value1').value;
});
});
<script src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
<div class="field">
<label for="value1">Introduce value</label>
<input type="text" id="value1" name="value1" value="" />
</div>
<div class="button-block">
<input type="submit" value="Click" />
</div>
<div id="output">
<h2>Result:</h2>
<textarea name="result" id="result"></textarea>
</div>
<script>
$( document ).ready(function() {
setTimeout(function(){
var val = document.getElementById('value1').innerHTML;
var generateHere = document.getElementById("result");
generateHere.innerHTML = val;
}, 2000);
});
</script>
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?
I have been trying to develop a extension but this is getting in my way.
This is my manisfest.json
{
"manifest_version":2,
"name":"erp",
"version":"1.0",
"permissions":["storage"],
"browser_action":{
"default_popup":"popup.html"
}
}
This is my popup.html
<!DOCTYPE html>
<html>
<head>
<script scr="popup.js"></script>
</head>
<body>
<textarea id="username"></textarea><br>
<!--<input type="password" name="password" id="password"><br>
<input type="button" id="show" value="Show saved Data">-->
<input type="button" id='save' value="Save"><br>
</body>
</html>
And this is my popup.js
window.onload = function(){
document.getElementById('save').onclick = function(){
var user = document.getElementById('username').value;
alert(user);
}}
Although there is nothing to alert. Please help.
you just misspelled the src attribute.
Your Code:
<!DOCTYPE html>
<html>
<head>
<script scr="popup.js"></script>
</head>
<body>
<textarea id="username"></textarea><br>
<!--<input type="password" name="password" id="password"><br>
<input type="button" id="show" value="Show saved Data">-->
<input type="button" id='save' value="Save"><br>
</body>
</html>
Correct Code:
<!DOCTYPE html>
<html>
<head>
<script src="popup.js"></script>
</head>
<body>
<textarea id="username"></textarea><br>
<!--<input type="password" name="password" id="password"><br>
<input type="button" id="show" value="Show saved Data">-->
<input type="button" id='save' value="Save"><br>
</body>
</html>
First thing i don't know why the username is in textarea?
If you have an empty alert please notice that textarea has a different behavior to input in their value.
<input type="text" value="value">
but textarea is not like this:
<textarea id="username">value</textarea>
But both works in javascript by 'value' property as you write.
And if you have no alert i must say that your code is true(I tested) and you have a problem before this:
window.onload = func...
Put an alert before to see if it works or not:
alert('Code is true until here');
window.onload = func...
I am trying to create a utility that will check if our site is down. The only way to do that is to login and if nothing is returned then the site is down. I've gotten it to the point where it will auto login, but not sure how to get it to check if the login was successful. Anyone got an idea?
