I am unable to split a variable that holds 5 fields from a form into a table in 5 different sections of the same row. I would appreciate any assistance.
// The section below this line is where the variable from the form input
// is inserted, but the role is not split into 5 different cells.
function getInfo() {
var info = document.getElementById("form1");
var text = "";
var i;
for (i=0; i < info.length; i++) {
text += info.elements[i].value;
}
document.getElementById("data").innerHTML = text;
// Log the form input into the console
console.log(text);
}
div.ui-input-text { width: 200px !important;}
button { width: 200px !important; }

If you want the data into different columns, you have to create the columns and append them to a row.
You do not want to concatenate the data into a single var, because you want to keep the data split up into columns.
You could do this:
function getInfo() {
const info = document.getElementById("form1");
const row = document.getElementById("data");
for (let i =0; i < info.length; i++) {
// Make a new column
const col = document.createElement('td');
// Make a new text node
const colText = document.createTextNode(info.elements[i].value);
// Append text to column
col.appendChild(colText);
// Append column to the row (id of data)
row.appendChild(col);
}
}
You need to add the table cell markup to your string, given your current approach.

The problem is that you are concatenating each field into a string; there is no delimiter in the string so there is no logical way to break it up. What you want to do instead is store each field in an array, then you can iterate over that to build up a HTML string, or better yet just use Array.prototype.join() to create the HTML for the cells you are creating.
function getInfo() {
var info = document.getElementById("form1");
var fields = []; // create an empty array
var i;
for (i=0; i < info.length; i++) {
fields.push(info.elements[i].value);
}
document.getElementById("data").innerHTML = '<td>' + fields.join('</td><td>') + '<td>';
}
document.getElementById('try-it').addEventListener('click', getInfo, false);

This will work, but it produces a table that can only have one row of data in it; every time you hit "Try It" the existing data will be replaced. To add more than one row, instead of targeting a particular row and inserting cells into it, create an entire row and append it to the table. Since you are already using jQuery, I'm using it in the below example.
function getInfo() {
// Create an array containing the values of all of the fields.
// First, select all of the input elements inside of the form,
// Then, use .map() to extract their values, finally use .get() to
// turn the jQuery object into an array.
var fields = $('#form1 input').map(function () {
return this.value;
}).get();
// create a new row and append it to the table.
$('#display-table').append('<tr><td>' + fields.join('</td><td>') + '<td></tr>');
}
// instead of using in-line event handlers, attach it in your code.
$('#try-it').on('click', getInfo);

I'm trying to perform a static crude operation. When user add a details on textbox it will stores in array of object and then that object print on table.

I think you forget update your data array.
Change your deleteRow function to
function deleteRow(btn) {
var cnfrmMessage = confirm("Are you sure want to Delete selected data? You cannot undo this action.");
if(cnfrmMessage == true){
var row = btn.parentNode.parentNode;
row.parentNode.removeChild(row);
// update your data (remove item by row id)
data = data.filter((item)=>item.id!==$(row).children()[0].innerText);
}
else{
alert("Cancelled..!!");
}
}
Your array is literally a 'data'. So you need a unique id for delete specific row or do something on this.
Other way, you can compare all fields in that row you want to delete, but it's not a good solution.
You need a way to identify the item in the list going off of the HTML element. Looks like you can use the id column (although usually it would be better to put something like that in an attribute). Then you can use filter:
Add the id to the deleteRow function.
deleteRow(this, ${data[i].id})
// Removes item with id.
var a = [
{id:1},
{id:2},
{id:3},
{id:4},
{id:5},
{id:6},
{id:7},
{id:8},
{id:9}
];
a.filter(item => item.id != deleteId);
I am looking to calculate a column within a table that is being created. I need the sum field to add up the values created from the form, which is created new rows for the table upon submit. Any way I can get the to add up the column sum? Each time a function updatetable() is run is creates another table row, and these are the rows I need calculated...currently the column holds a "184" as a holding place for where the calculation would take place.

The entire process of collecting data from the first input-field and shipping to second input-field2 is working perfectly but so that the value actually goes to the second input-field i must delete some letter from first input-field and re-enter some number so that the value actually goes to second-input.
Gif of doubt.
$(document).ready(function () {
$(function () {
var $cepAddressRouteTransporterGoogleMaps = $('#postal_code');
var $cepAddressRouteTransporter = $('#cepAddressRouteTransporter');
function onChange() {
$cepAddressRouteTransporter.val($cepAddressRouteTransporterGoogleMaps.val());
};
$('#postal_code')
.change(onChange)
.keyup(onChange);
});
});
First input represents this field postal_code & Second input represents this field cepAddressRouteTransporter.

Thanks for help!
you have to call your function onChange when the DOM is ready
onChange();
when you update the value, trigger the DOM event.
$('#postal_code').trigger('change');
$(function() {
var $cepAddressRouteTransporterGoogleMaps = $('#postal_code');
var $cepAddressRouteTransporter = $('#cepAddressRouteTransporter');
function onChange() {
$cepAddressRouteTransporter.val($cepAddressRouteTransporterGoogleMaps.val());
};
$('#postal_code').change(onChange).keyup(onChange);
// fire as soon as DOM is ready
onChange();
var t = window.setInterval(function(){
var n = Math.floor(Math.random() * 100000);
$('#postal_code').val(n);
// when you update the value, trigger the DOM event
$('#postal_code').trigger('change');
},1000);
});

You need to add the event listener outside the function.
The listener is listening (clues in the name) for a mouse 'click' event on that element. When the event happens i.e you click on the element, it calls the function that it is assigned, in your case: parseNumber.
So since you are adding the event listener inside the function, it never gets added (as the function never gets called).
It should all work if you move the lines:
var x = document.getElementById( "myBtn" );
x.addEventListener("click", parseNumber);
outside the function. :)
I thnik no one actually read the question, if you already had a working example then changing onclick to eventListener is no problem:
var parseNum = document.getElementById('parse-number');
function parseNumber() {
var myForm = document.getElementById( "myForm" );
myForm.areaCode.value = "";
myForm.number.value = "";
var completeNumber = myForm.input.value.replace(/\s/g, '');
var areaCode = completeNumber.substr(1,3);
var tokens2 = completeNumber.substr(5).split( "-" );
myForm.areaCode.value = areaCode;
myForm.number.value = tokens2[0] + "-" + tokens2[1];
}
parseNum.addEventListener("click", parseNumber);

Change your code to this where eventListener is added outside the bounded function. Otherwise it will repeatedly bind an eventListener to the button.
Also place your script.js on the bottom of the HTML page. Because when the script executed the DOM element is not found since the DOM is not rendered at the script execution time.

I want to place asterisk in the right side of the each text box individually when I am submitting the empty form/field. The code is working but asterisk is displaying in the end of the form.
This is my code:

<title></title>
<style type="text/css">

input { text-align:center; border:2px solid #CCC; }
#wrap { width:400px; height:200px; margin:20px; padding:10px; }
#une { margin-top:10px; }
#reg {margin-top:10px; }
.a13B { color:#F00; }
.cntr { text-align:center; }
</style>
</head>

Here is your code:
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
$('#submitBtn').on('click', function(e) {
debugger;
e.preventDefault();
var fields = document.getElementsByTagName('input');
for (var i = 0; i < fields.length; i++) {
if (fields[i].hasAttribute('required')) {
if (fields[i].value == "") {
fields[i].classList.add('redBorder');
$(fields[i]).after('*');
} else {
fields[i].classList.remove('redBorder');
}
}
}
});
});
</script>
<style>
.redBorder {
border: 2px solid red;
border-radius: 2px;
}
</style>
</head>
<form novalidate>
<input type="text" placeholder="first name" required/><br/><br/>
<input type="text" placeholder="last name" /><br/><br/>
<button id="submitBtn" value="Submit">Submit</button>
</form>
</html>
Use span element to display asterisk at the end of text box. Try this :
<input type="text" id="name"/> <span style="color:red"> * </span>
Hope this solves your requirement.
Why bother with all that mess?
<input type="text" name="fnametxt" required />*
<input type="email" name="emailtxt" required />*
<input type="submit" value="Register" />
JavaScript required: none at all
With the help of jquery after() method, you can achieve this.
$(fields[i]).after("<span class='redColor'>*</span>");
I have also added code to show red border for required input field.
Note: If you use <form> tag, then HTML5 will automatically does the validation and your script will not execute, so to prevent that use novalidate attribute in the form tag or just remove the form tag.
$(document).ready(function() {
$('#submitBtn').on('click', function(e) {
e.preventDefault();
var fields = document.getElementsByTagName('input');
for (var i = 0; i < fields.length; i++) {
if (fields[i].hasAttribute('required')) {
if (fields[i].value == "") {
fields[i].classList.add('redBorder');
$(fields[i]).after("<span class='redColor'>*</span>");
} else {
fields[i].classList.remove('redBorder');
}
}
}
});
});
.redBorder {
border: 2px solid red;
border-radius: 2px;
}
.redColor{
color:red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form novalidate>
<input type="text" placeholder="first name" required/><br/><br/>
<input type="text" placeholder="last name" /><br/><br/>
<button id="submitBtn" value="Submit">Submit</button>
</form>
