JavaScript: Need input element to change options based on entered data

I have a page, where I need to filter through all kinds of data (served as JSON variable) using just pure javascript. Everything works nicely until I try to implement a datalist where the contents of that list are updated in realtime, based on user input.
var data = [{name:"Paul"},{name:"Alex"},{name:"Laura"}] // This is just example object
function updateSearch() {
let search = document.getElementById('search').value;
let options = document.getElementById('searchList');
options.innerHTML = "";
if (search.length >= 2) {
search = search.toLowerCase();
for (let d of data) {
if (d.name.toLowerCase().search(search) === 0) {
options.innerHTML += `
<option>${d.name}</option>
`;
}
}
}
}
<datalist id='searchList'></datalist>
<input type="search" id="search" list='searchList' onchange="updateSearch()">
The goal is to not show the full list of names until at least 2 characters are entered, but it just won't update until the user clicks out focuses back to search input.

One solution to achieve what you require would be to replace the event type that updateSearch() is bound to from onchange to onkeyup:
const data = [
{ name : "Foo" },
{ name : "Bar" },
{ name : "Bing" },
{ name : "Bong" },
{ name : "Boo!" }];
function updateSearch() {
let search = document.getElementById('search').value;
let options = document.getElementById('searchList');
options.innerHTML = "";
if (search.length >= 2) {
search = search.toLowerCase();
for (let d of data) {
if (d.name.toLowerCase().search(search) === 0) {
options.innerHTML += `
<option>${d.name}</option>
`;
}
}
}
}
<datalist id='searchList'></datalist>
<!-- Update to onkeyup -->
<input type="search" id="search" list='searchList' onkeyup="updateSearch()">
Doing this will cause the datalist to interactivly update as the user types. Hope that helps!

Trying to dupe inputs/textareas with variables

I am currently trying to add a button, that when I click it - a list of questions appear (with textareas/inputs), every textarea/input has his own ID and I'm trying to get all of the answers printed into one form.
<h5>QUESTION BULK 1/h5>
<div id="question1">
<h4">#1</h4>
<p>Relative name?: <input id="a_relative">
<p>Age: <input id="a_age">
<p>What makes him your relative?: <input id="a_what">
</div>
I'm trying to get a button to make it add that bulk of questions, so the user can add the relevant amount.
e.g:
<button onClick="clickMe()">Add</button>
All of the data from the inputs should be later taken and put into a certain "answer sheet" form.
e.g:
function clickMe() {
var relative = document.getElementById("a_relative").value;
var age = document.getElementById("a_age").value;
var what = document.getElementById("a_what").value;
var generatedForm = " Name: "+relative+"\n\
Relative age: "+age+"\n\
Reason he/she is your relative: "+what+".";
document.getElementById("X").value = clickMe // put everything in a textarea of example,
}

Try using JQuery it makes id that you do not have to use
document.getElementById("a_relative").value;

Here's a quick solution using modern JS methods.
// Use an array to contain the questions
const questions = [
// Each question has an id, question text, and an
// object containing the input information
{ id: 1, text: 'Name', input: { el: 'input', type: 'text' } },
{ id: 2, text: 'Age', input: { el: 'input', type: 'number' } },
{ id: 3, text: 'How', input: { el: 'textarea' } },
];
// Grab and cache the elements from the page
const main = document.querySelector('.main');
const form = document.querySelector('form');
const output = document.querySelector('#output');
const add = document.querySelector('.add');
const show = document.querySelector('.show');
// Add event listeners for the buttons
add.addEventListener('click', handleAdd, false);
show.addEventListener('click', handleShow, false);
// When add button is clicked...
function handleAdd() {
// ...produce html for each question in the array...
const html = questions.map(question => {
return createQuestionHTML(question);
}).join('');
// ...and add it to the form.
form.insertAdjacentHTML('beforeend', html);
}
function createQuestionHTML(question) {
// Grab the properties/values from the question object
const { id, text, input: { el, type } } = question;
// Based on the input type choose whether an input
// or a textarea should be displayed.
// Ensure they have an answer class, and a data attribute
// with question text
let input = type === 'input'
? `<${el} type=${type} class="answer" data-to="${text}" />`
: `<${el} class="answer" data-to="${text}"></${el}`;
// Return a section containing a heading of the question text,
// and the appropriate input element
return (
`<section class="question">
<h5>${id} - ${text}</h5>
${input}
</section>`
);
}
// When the show button is clicked...
function handleShow() {
// ...select all the elements with the answer class within the form
const answers = form.querySelectorAll('.answer');
// Hide the form
main.classList.add('hidden');
// Log the value and data-to attribute text to console
[...answers].forEach(({ value, dataset }) => {
output.insertAdjacentHTML('beforeend', `<div>${dataset.to} => ${value}`);
});
}
form, .buttons { margin-bottom: 1em; }
h5 { margin-bottom: 0.2em; }
.hidden { display: none }
<section class="main">
<form></form>
<section class="buttons">
<button class="add">Add questions</button>
<button class="show">Show answers</button>
</section>
</section>
<div id="output" />

How do I change this Contact Form's Javascript so that IF a key is something else, perform different action?

I have a Contact Form that utilizes Google Scripts. It successfully sends the email and formats it decently to my inbox, but there are 2 problems:
-I need it so that IF var key is equal to 'Action', then do not display it in the email it sends. Because right now, "Action send_message" is getting included in the email and I don't like that.
For this, I have unsuccessfully tried things like:
for (var idx in order) {
var key = order[idx];
//Skip this entry into the email output if it is the Action
if( key === 'Action') {
continue
}
It seems to not react to this code at all.
-I also need it so that if a city is selected, e.g. Alachua, that the email says 'Alachua' instead of 'Florida_Alachua'. But I can't add a NAME to an option since apparently options don't have that property. I also can't do the quick fix of changing the VALUE of the <option> to resolve this step, because of other code I have that conflicts with this route.

finally, this is the extra code that would break if I simply tried changing the value of option to, e.g., 'Alachua' instead of 'Flordia_Alachua'. https://jsfiddle.net/hmatt843/504dgmqy/19/
Thanks for any and all help.

Try console.log(key) before if( key === 'Action'). I think you'll find that key never equals 'Action', exactly. Looks like you'll need if( key === 'action'), instead.
If you wish to remove part of string value, try the replace method: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace
It also looks like you're trying to work with elements[k].name when you mean to be working with elements[k].value.
I believe your code should look something like...
function(k) {
if(elements[k].value !== undefined) {
return elements[k].value.replace('Florida_', '');
// special case for Edge's html collection
} else if(elements[k].length > 0){
return elements[k].item(0).value.replace('Florida_', '');
}
}
... or something to that effect.
In the future, you may want to make it easier for folks trying to help you by posting only the portions of code your having trouble with, and breaking your questions into different posts. A lot to sift through up there.
Hope this helped.

The split() method splits a String object into an array of strings by separating the string into substrings, using a specified separator string to determine where to make each split.
Var splitValue = elements[k].item(0).value.split("");
splitValue[1] will give you a string of characters after the delimeter () in this case.

add dynamic click on checkbox and to get inputName in jQuery

I have a dynamic input which will have checkbox to hide the inputs when you tick the checkbox, at the moment I'm trying to add click="getChk() to the checkbox however it was only giving me the last index inputName.
Say I have input Ids (code, sku, id).
My dynamic inputs and checks code line is
for (var x = 0; x < searchParams.length; x++) {
var container = $('#checkBox');
var inputs = container.find('input');
var id = inputs.length + 1;
var inputName = searchParams[x].name;
$('<textarea />', { id: inputName, name: inputName, placeholder: inputName, rows: "2", class: "search-area-txt col-sm-12" }).appendTo(searchbox);
$('<input />', { type: 'checkbox', id: 'x' + id, name: inputName }).appendTo(checkBox);
$('<label />', { 'for': 'x' + id, text: inputName, id: inputName, name: inputName }).appendTo(checkBox);
}
But this will need to be saved in the localStorage so when refresh it will persist the input to be hidden when its exists in the localStorage.
Edit: the code below should save the name in the localStorage in array form.
var inputNames = [];
getChk(id){
var indexOfItem = inputNames.indexOf(name)
if (indexOfItem >= 0) {
inputNames.splice(indexOfItem, 1);
} else {
inputNames.push(name);
}
localStorage.setItem('chked', JSON.stringify(inputNames))
}
My attempt is by adding .click(function(){})
$('<input />', { type: 'checkbox', id: 'x' + id, name: inputName }).appendTo(checkBox).click(function(){
getChk(id); // only gives me the id name
});
HTML inputs and checkbox html

The issue is because when the click event handler runs the for loop has completed, therefore the id variable holds the last value.
To fix this, amend your click handler to read the id attribute directly from the element which raised the event:
$('<input />', { type: 'checkbox', id: 'x' + id, name: inputName }).appendTo(checkBox).click(function() {
getChk(this.id);
});
Also, as spotted by #guest271314, the correct method when setting localStorage data is setItem(), not set():
localStorage.setItem('checked', id);

you can try below code
getChk(e){
localStorage.set('checked', this.id);
console.log('input id>> ', this.id);
}
.click(getChk);

Copy form elements by field ID instead of by field name

I found a file called copyShipping.js that allows me to copy form elements from one form to another by the click of a checkbox. However, it copies by name of each field rather than ID. Below is the code. How do I get it to copy by ID? I know there's a getElementByID on Javascript but I don't know how to implement it. Ideally I would just like the code changed for me. Thanks.
function eCart_copyBillingToShipping(cb){
if(cb.checked){ // Only copy when the checkbox is checked.
var theForm = cb.form;
// The number of elements must match in billingFields and shippingFields. The type of input element must also match between the arrays.
var billingFields = new Array('firstname', 'lastname', 'email', 'phone', 'fax', 'street1', 'street2', 'city', 'state_province', 'StateOther', 'other_state_province', 'postcode', 'other_postcode', 'country');
var shippingFields = new Array('shipping_firstname', 'shipping_lastname', 'shipping_email', 'shipping_phone', 'shipping_fax', 'shipping_street1', 'shipping_street2', 'shipping_city', 'shipping_state_province', 'ShippingStateOther', 'other_shipping_state_province', 'shipping_postcode', 'other_shipping_postcode', 'shipping_country');
for(var i=0;i<billingFields.length;i++){
var billingObj = theForm.elements[billingFields[i]];
var shippingObj = theForm.elements[shippingFields[i]];
if(billingObj && shippingObj){
if(billingObj.tagName){ // non-radio groups
var tagName = billingObj.tagName.toLowerCase();
if(tagName == 'select'){
shippingObj.selectedIndex = billingObj.selectedIndex;
}
else if((billingObj.type && shippingObj.type ) && (billingObj.type == 'checkbox' || billingObj.type == 'radio')){
shippingObj.checked = billingObj.checked;
}
else{ // textareas and other inputs
shippingObj.value = billingObj.value;
}
}
else if(billingObj.length){ // radio group
for(var r=0;r<billingObj.length;r++){
shippingObj[r].checked = billingObj[r].checked;
}
}
}
}
}
}

It is always recommended to access the elements using Id. Also it is recommended to have id and name same.
Try this.
function eCart_copyBillingToShipping(cb){
if(cb.checked){ // Only copy when the checkbox is checked.
var theForm = cb.form;
// The number of elements must match in billingFields and shippingFields. The type of input element must also match between the arrays.
var billingFields = new Array('firstname', 'lastname', 'email', 'phone', 'fax', 'street1', 'street2', 'city', 'state_province', 'StateOther', 'other_state_province', 'postcode', 'other_postcode', 'country');
var shippingFields = new Array('shipping_firstname', 'shipping_lastname', 'shipping_email', 'shipping_phone', 'shipping_fax', 'shipping_street1', 'shipping_street2', 'shipping_city', 'shipping_state_province', 'ShippingStateOther', 'other_shipping_state_province', 'shipping_postcode', 'other_shipping_postcode', 'shipping_country');
for(var i=0;i<billingFields.length;i++){
//assuming that now array contains id (not name)
var billingObj = theForm.getElementById(billingFields[i]);
var shippingObj = theForm.getElementById(shippingFields[i]);
if(billingObj && shippingObj){
if(billingObj.tagName){ // non-radio groups
var tagName = billingObj.tagName.toLowerCase();
if(tagName == 'select'){
shippingObj.selectedIndex = billingObj.selectedIndex;
}
else if((billingObj.type && shippingObj.type ) && (billingObj.type == 'checkbox' || billingObj.type == 'radio')){
shippingObj.checked = billingObj.checked;
}
else{ // textareas and other inputs
shippingObj.value = billingObj.value;
}
}
else if(billingObj.length){ // radio group
for(var r=0;r<billingObj.length;r++){
shippingObj[r].checked = billingObj[r].checked;
}
}
}
}
}
}
