I am trying to create a form that when submitted will just output the two values to the console. However, when I run it, only the email field is being displayed and the name field is just showing 'undefined'.
I have created a JSFiddle of what I have so far.
https://jsfiddle.net/hbzxcvjj/1/
JS:
var name = document.getElementById("name");
var email = document.getElementById("email");
var submitButton = document.getElementById("btn-signup");
var sendInfo = function(){
console.log(name.value);
console.log(email.value);
}
submitButton.onclick = sendInfo;
try moving your variable definitions into the function, this is how it should look:
var submitButton = document.getElementById("btn-signup");
var sendInfo = function(){
var name = document.getElementById("name");
var email = document.getElementById("email");
console.log(name.value);
console.log(email.value);
}
submitButton.onclick = sendInfo;
https://jsfiddle.net/hbzxcvjj/2/
see the working fiddle
Try with alternate method:
submitButton.addEventListener("click", sendInfo);

I have been working on a small contact form for a webpage and I used some code from a website to create the form. My problem is that the submit button wants to post the data and all is the submit button to create a message alert, and also redirect to another page after the message appears..
Any help would be greatly appreciated! Thanks!
here is the JS:
// Fetching HTML Elements in Variables by ID.
var x = document.getElementById("form_sample");
var createform = document.createElement('form'); // Create New Element Form
createform.setAttribute("action", ""); // Setting Action Attribute on Form
//createform.setAttribute("method", "post"); // Setting Method Attribute on Form
x.appendChild(createform);
var heading = document.createElement('h2'); // Heading of Form
heading.innerHTML = "Contact Form ";
createform.appendChild(heading);
var line = document.createElement('hr'); // Giving Horizontal Row After Heading
createform.appendChild(line);
var linebreak = document.createElement('br');
createform.appendChild(linebreak);
var namelabel = document.createElement('label'); // Create Label for Name Field
namelabel.innerHTML = "Your Name : "; // Set Field Labels
createform.appendChild(namelabel);
var inputelement = document.createElement('input'); // Create Input Field for Name
inputelement.setAttribute("type", "text");
inputelement.setAttribute("name", "dname");
createform.appendChild(inputelement);
var linebreak = document.createElement('br');
createform.appendChild(linebreak);
var emaillabel = document.createElement('label'); // Create Label for E-mail Field
emaillabel.innerHTML = "Your Email : ";
createform.appendChild(emaillabel);
var emailelement = document.createElement('input'); // Create Input Field for E-mail
emailelement.setAttribute("type", "text");
emailelement.setAttribute("name", "demail");
createform.appendChild(emailelement);
var emailbreak = document.createElement('br');
createform.appendChild(emailbreak);
var messagelabel = document.createElement('label'); // Append Textarea
messagelabel.innerHTML = "Your Message : ";
createform.appendChild(messagelabel);
var texareaelement = document.createElement('textarea');
texareaelement.setAttribute("name", "dmessage");
createform.appendChild(texareaelement);
var messagebreak = document.createElement('br');
createform.appendChild(messagebreak);
var submitelement = document.createElement('input'); // Append Submit Button
submitelement.setAttribute("type", "submit");
submitelement.setAttribute("name", "dsubmit");
submitelement.setAttribute("value", "Submit");
createform.appendChild(submitelement);
If I'm understanding your question correctly, you want the page to verify before submitting, correct?
If so, you can add a listener which optionally cancels the submit action.
createform.addEventListener("submit", function() {
return confirm("Continue?");
});
You can add an event listener for submit event on submit button. Prevent it's default behavior, show an alert and then redirect to whatever page you want
createform.addEventListener("submit", function(e) {
e.preventDefault();
var msg = window.confirm("Want to go to other page?");
if (msg) {
window.location.href = "url";
}
})
everything working as my desire but when I click on book room button it can not generate input field for me but its shows as [object HTMLFormElement] here is my code
function booking(roomBooking){
var f = document.createElement("form");
var in1 = document.createElement("input");
in1.type = "text";
in1.name = "user_name";
in1.id = "user_name1";
f.appendChild(in1);
document.getElementById("name").innerHTML=f;
}
I want to show form when I clicked on book room button.
Here you are:
You should just apply your f variable to "#name" element by using appendChild() function, because "f" it's an object and you cannot directly use it.
function booking(roomBooking) {
var f = document.createElement("form");
var in1 = document.createElement("input");
in1.type = "text";
in1.name = "user_name";
in1.id = "user_name1";
f.appendChild(in1);
document.getElementById("name").appendChild(f);
}
I am trying to create a fill button that will fill the input values with the a default. When I go to click the fill button the defaults shows up for 2 seconds and then disappears. How do I get the information to stay without it clearing itself.
var enter, replace, FirstName, Telephone, email, BithDate, LastName, ZipCode, SS, Cash;
window.onload = function() {
//calls the functions when buttons clicked
replace = document.getElementById("fill");
replace.addEventListener("click", filler);
enter = document.getElementById("enter");
enter.addEventListener("click", calculate);
var clear = document.getElementById("clear");
clear.addEventListener("click", clear);
}
function filler() {
//list the default values to fill when the fill button is clicked
FirstName = document.getElementById("FirstName").value = "Jane";
Telephone = document.getElementById("tel").value = "888-777-9999";
email = document.getElementById("email").value = "JaneDoe#example.com";
BithDate = document.getElementById("birth").value = "2017";
LastName = document.getElementById("LastName").value = "Doe";
ZipCode = document.getElementById("zip").value = "12345";
SS = document.getElementById("SocSec").value = "123-45-6789";
Cash = document.getElementById("income").value = "123456";
}
function clear() {
//clears the form and resets it to the default
document.getElementById("form").reset();
}
You named your local variable for the clear button "clear" which shadows the global clear function, so clear.addEventListener("click", clear); doesn't work. Try renaming the local variable to something like clearBtn.
I have One simple registration Form which is developed in C#.Net. This form also contain one Grid view which display data from database.In this,I want to disable Insert button when i select particular raw data. and i had develop this code in jquery. I used below code.
function DoStuff(lnk) {
debugger;
var grid = document.getElementById('GridView1');
var cell, row, rowIndex, cellIndex;
cell = lnk.parentNode;
row = cell.parentNode;
rowIndex = row.rowIndex;
cellIndex = cell.cellIndex;
var rowId = grid.rows[rowIndex].cells[0].textContent;
var rowname = grid.rows[rowIndex].cells[1].textContent;
var rowcontact = grid.rows[rowIndex].cells[2].innerHTML;
var rowaddress = grid.rows[rowIndex].cells[3].innerHTML;
var rowemail = grid.rows[rowIndex].cells[4].innerHTML;
var Id = document.getElementById('txt_Id');
var name = document.getElementById('txt_Name');
var contact = document.getElementById('txt_PhoneNumber');
var address = document.getElementById('txt_Address');
var email = document.getElementById('txt_EmailId');
Id.value = rowId;
name.value = rowname;
contact.value = rowcontact;
address.value = rowaddress;
email.value = rowemail;
document.getElementById('Button1').disabled = true;
};
But when i run that page it becomes disable and immediately enable automatically.....:(
Can anyone give me solution ???
You have to call this function after form is completely loaded.
Use below code to make it that happen if you are using jQuery.
$( document ).ready(function() {
DoStuff(lnk);
});
I made the following code to replace form fields in a page that I can't edit but only manipulate. However, the code does nothing. In chrome console when I print a variable it works fine. The code is below:
//GET val from drop DROP DOWN
var office_id = FieldIDs["OfficeName"];//Gets the input id
var offices;//gets the value from the drop down
$("#FIELD_"+office_id).change(function(){
offices = $(this).val();
}).change();
//The below gets the id's of all the input fields
var address_id = FieldIDs["Address"];
var address2_id = FieldIDs["Address2"];
var city_id = FieldIDs["City"];
var state_id = FieldIDs["State"];
var zip_id = FieldIDs["Zip"];
var phone_4id = FieldIDs["Number4"];//phone
var phone_id = FieldIDs["Number1"];//fax
var pdfm4 = FieldIDs["pdfm4"];
var pdfm = FieldIDs["pdfm"];
if(offices == "SoCal Accounting"){
$('#FIELD_'+address_id).val("7421 Orangewood Avenue");
$('#FIELD_'+address2_id).val("");
$('#FIELD_'+city_id).val("Garden Grove");
$('#FIELD_'+state_id).val("CA");
$('#FIELD_'+zip_id).val("92841");
$('#FIELD_'+phone_4id).val("+1 714.901.5800");//phone
$('#FIELD_'+phone_id).val("+1 714.901.5811");//fax
}
