I am trying to get the date and department info stored into an array, when a user inputs a value into my HTML. When I look at the console, I see it is being saved as E.fn.init. Here is my HTML code:
<form>
<p><b>Date:</b><input id="date_out" type='date' required /></p>
<p><b>Department:</b><input id='department_out' type='text' required /></p>
<button class="btn btn-primary" type="submit" id='submit' >SUBMIT</button>
</form>
And here is my Javascript Code:
let count = 1;
// Handler to Submit Data
$('#submit').click(() =>{
$('form').on('submit', function(e){
e.preventDefault();
const date_out = $("#date_out").val();
const department_out = $("#department_out").val();
let data = [];
// Iterate over all rows and store data
for (let i = 1; i <= count; i++){
// Skip Row if it was Removed
if (!$(`tr[index=${i}]`).length) continue;
// Store all Info from this row
let assetInfo = {
date_out: $(`#date_out${i}`).val(date_out),
department_out: $(`#department_out${i}`).val(department_out),
}
data.push(assetInfo);
console.log(data);
}
});
});
And the console prints the array as; date_out: E.fn.init, department_out: E.fn.init. How do I get it to save whatever the user inputs in the array?
I am not quite sure what is your HTML structure but as I understand, you have a table and you want to store each row in a data,
here is how I advise you to do it:
In my Table called depTable, I have each row with a unique ID like this:
date_out_1
department_out_1
so, when I want to access that, I just want to create that ID which is an easy task while I can get how many rows I have in that table, like this:
// Get ROW COUNT FROM TABLE
var count = $('#depTable tr').length;
Now, if you combine in For loop you will get all IDs
for (let i = 1; i <= count; i++){
var idDate = "#date_out_" + i;
var idDep = "#department_out_" + i;
}
here is my all code, hope I helped to solve your problem.

I have a button that the user clicks on to add a new row to the bottom of an input table. I would like this to also increment the id. So the next row would have desc2, hours2, rate2 and amount2 as the id. Is there a way to do this in the JavaScript function.
Also - just want to check my logic on this. After the user completes the filled out form, I will be writing all the data to a mysql database on two different tables. Is this the best way to go about this? I want the user to be able to add as many lines in the desc_table as they need. If this is the correct way to be going about this, what is the best way to determine how many lines they have added so I can insert into the db table using a while loop?
JS file:
function new_line() {
var t = document.getElementById("desc_table");
var rows = t.getElementsByTagName("tr");
var r = rows[rows.length - 1];
var x = rows[1].cloneNode(true);
x.style.display = "";
r.parentNode.insertBefore(x, r);
}
HTML:
<table id="desc_table">
<tr>
<td><font><br><h3>Description</h3></font></td>
<td><font><h3>Hours</h3></font></td>
<td><font><h3>Rate</h3></font></td>
<td><font><h3>Amount</h3></font></td>
<td></td>
</tr>
<tr>
<td ><textarea name="description" id="desc1" ></textarea></td>
<td> <input type="text" name="hours" id="hours1" ></td>
<td> <input type="text" name="rate" id="rate1"></td>
<td><input type="text" name="amount" id="amount1"></td>
<td>
<button type="button" name="add_btn" onclick="new_line(this)">+</button>
<button type="button" name="delete_btn" onclick="delete_row(this)">x</button>
</td>
</tr>
</table>
Thank you!
Check this code.After appending the row it counts the number of rows and and then assigns via if condition and incremental procedure the id's:
function new_line() {
var t = document.getElementById("desc_table");
var rows = t.getElementsByTagName("tr");
var r = rows[rows.length - 1];
var x = rows[1].cloneNode(true);
x.style.display = "";
r.parentNode.insertBefore(x, r);
for(var i=1;i<rows.length;i++){
if(rows[i].children["0"].children["0"].id.match((/desc/g))){
rows[i].children["0"].children["0"].id='desc'+i;
}
if(rows[i].children["1"].children["0"].id.match((/hours/g))){
rows[i].children["1"].children["0"].id='hours'+i;
}
if(rows[i].children["2"].children["0"].id.match((/rate/g))){
rows[i].children["2"].children["0"].id='rate'+i;
}
if(rows[i].children["3"].children["0"].id.match((/amount/g))){
rows[i].children["3"].children["0"].id='amount'+i;
}
}
}
<table id="desc_table">
<tr>
<td><font><br><h3>Description</h3></font></td>
<td><font><h3>Hours</h3></font></td>
<td><font><h3>Rate</h3></font></td>
<td><font><h3>Amount</h3></font></td>
<td></td>
</tr>
<tr>
<td ><textarea name="description" id="desc1" ></textarea></td>
<td> <input type="text" name="hours" id="hours1" ></td>
<td> <input type="text" name="rate" id="rate1"></td>
<td><input type="text" name="amount" id="amount1"></td>
<td>
<button type="button" name="add_btn" onclick="new_line(this)">+</button>
<button type="button" name="delete_btn" onclick="delete_row(this)">x</button>
</td>
</tr>
</table>
Please change variable names for more descriptive. :)
Example solution...
https://jsfiddle.net/Platonow/07ckv5u7/1/
function new_line() {
var table = document.getElementById("desc_table");
var rows = table.getElementsByTagName("tr");
var row = rows[rows.length - 1];
var newRow = rows[rows.length - 1].cloneNode(true);
var inputs = newRow.getElementsByTagName("input");
for(let i=0; i<inputs.length; i++) {
inputs[i].id = inputs[i].name + rows.length;
}
var textarea = newRow.getElementsByTagName("textarea")[0];
textarea.id = textarea.name + rows.length;
table.appendChild(newRow);
}
Note that I removed/edited below fragment.
x.style.display = "";
r.parentNode.insertBefore(x, r);
You could do this a lot easier with jquery or another dom manipulation language, but with vanilla JS here's an example of simply looping through the new row's inputs & textarea and incrementing a counter to append.
var count = 1;
function new_line() {
count++;
var t = document.getElementById("desc_table");
var rows = t.getElementsByTagName("tr");
var r = rows[rows.length - 1];
var x = rows[1].cloneNode(true);
x.style.display = "";
r.parentNode.insertBefore(x, r);
// update input ids
var newInputs = Array.from(x.getElementsByTagName('input'))
.concat(Array.from(x.getElementsByTagName('textarea')));
newInputs.forEach(function(input) {
var id = input.getAttribute('id').replace(/[0-9].*/, '');
input.setAttribute('id', id + count);
});
}
<table id="desc_table">

Since you've been adding more and more requirements in the comments, the innerHTML += "" approach stops working.
I advice you to create elements using document.createElement and add them to your document using Node.appendChild.
It's not really an answer to the initial question, but I figured it helps you more than continuing conversation in the comments. Maybe you can edit your question to reflect the additional requirements.
Let me know if there's stuff I used that you don't yet understand. Happy to elaborate!
var inputIds = ["ins_name", "gpa", "da"];
var inputElements = inputIds.map(getById);
var tbody = getById("display");
// Create a new row with cells, clear the inputs and add to tbody
function addRow() {
// Create a row element <tr></tr>
var row = document.createElement("tr");
inputElements.forEach(function(input) {
// For each input, create a cell
var td = document.createElement("td");
// Add the value of the input to the cell
td.textContent = input.value;
// Add the cell to the row
row.appendChild(td);
// Clear the input value
input.value = "";
});
// Add the new row to the table body
tbody.appendChild(row);
}
getById("btn_test").addEventListener("click", addRow);
// I added this function because document.getElementById is a bit too long to type and doesnt work with `map` without binding to document
function getById(id) {
return document.getElementById(id);
}
Institution : <input type="text" name="ins_name" id="ins_name" /><br>
GPA : <input type="text" name="gpa" id="gpa" /><br>
Degree Awarded : <input type="text" name="da" id="da" /><br>
<input type="button" id="btn_test" name="btn_test" value="Add Test"/><br>
<table>
<thead>
<tr>
<th>Institution</th>
<th>GPA</th>
<th>Degree</th>
</tr>

<tbody id="display">

</table>
I have then following table:
<table style="width:100%" id="testTable">
<tr>
<th>length per</th>
<th>width per</th>
<th>length</th>
<th>width</th>
<th>total</th>
</tr>
<tr align='right'>
<td>
<input type="text" name="length-per-input">

<td>
<input type="text" name="width-per-input">

<td>
<input type="text" name="length-total-input">

<td>
<input type="text" name="total-output" disabled="disabled">
</td>
</tr>
<tr align='right'>
<td>
<input type="text" name="length-per-input">
</td>
<td>
<input type="text" name="width-per-input">
</td>
<td>
<input type="text" name="length-total-input">
</td>
<td>
<input type="text" name="width-total-input">
</td>
<td>
<input type="text" name="total-output" disabled="disabled">
</td>
</tr>
</table>
<input type=button value='+' onclick="addRow()" />
<input type=button value='Calculate' onclick="Calculate()" />
I also have the javascript which adds the value and puts it in total:
<script>
function Calculate() {
var lengthPerInput = $("input[name='length-per-input']").val();
var widthPerInput = $("input[name='width-per-input']").val();
var lengthTotal = $("input[name='length-total-input']").val();
var widthTotal = $("input[name='width-total-input']").val();
var total = (lengthTotal/lengthPerInput) + (widthTotal/widthPerInput);
$("input[name='total-output']").val(total);
}
</script>
The aim here is to have it iterate over the two rows, then add each one separately.
I know how to get each row by using:
$('#testTable tr').each(function(){
console.log(this);
$(this).find('length-per-input').each(function(){
console.log(this);
})
})
But using the row (accessed via "this") I don't know how to get the correct cells, get their value, then perform the calculate on that row for the total.
Any advice on this please? Thank you!
function Calculate(tr_row) {
var lengthPerInput = tr_row.find("input[name='length-per-input']").val();
var widthPerInput = tr_row.find("input[name='width-per-input']").val();
var lengthTotal = tr_row.find("input[name='length-total-input']").val();
var widthTotal = tr_row.find("input[name='width-total-input']").val();
var total = (lengthTotal/lengthPerInput) + (widthTotal/widthPerInput);
tr_row.find("input[name='total-output']").val(total);
}
For every row you call function to summ the values
To the function you pass the row, then it can collect values on that row
$('#testTable tr').each(function(){
Calculate($(this))
})
You can use each() function to iterate through table and use find() function to find cell values.
function Calculate() {
$('#testTable tr').each(function() {
var lengthPerInput = $(this).find("input[name='length-per-input']").val();
var widthPerInput = $(this).find("input[name='width-per-input']").val();
var lengthTotal = $(this).find("input[name='length-total-input']").val();
var widthTotal = $(this).find("input[name='width-total-input']").val();
var total = (lengthTotal/lengthPerInput) + (widthTotal/widthPerInput);
$(this).find("input[name='total-output']").val(total);
});
}

How to get a table cell value using jQuery?
Created textbox in javascript, need those value to pass in arrays to add them ?
how do I do that ?
I just want my code to be short and simple
I'm stuck!
Code:
<html>
<head>
<title> 2 NUM ADD VIA ARRAY </title>
</head>
<body bgcolor= "red" </body>
<script type = "text/javascript">
function sum()
{
var sum = [],i=0;
sum[i]= document.getElementById('i+1').value;
alert("sum =" + sum);
}
</script>
<table border=2>
<TR>
<TD>
<input type="text" id="1" /input>
</TD>
<TD>
<input type="text" id="2" /input>
</TD>
</TR>
</table>
<button name="btHello" onclick="sum();">sum</button>
</html>
Usage of Array in this case is not required according to me.I suggest you to do this even without using arrays. This makes your code simple and short
<html>
<head>
<title> 2 NUM ADD VIA ARRAY </title>
</head>
<body bgcolor= "red" </body>
<script type = "text/javascript">
function sum()
{
var sum= 0;
$('.textbox').each(function() {
sum += Number($(this).val());
});
alert(sum);
}
</script>
<form>
<table border=2>
<TR>
<TD>
Text 1 :<input type="text" class="textbox" id="1" />
</TD>
<TD>
Text 2 :<input type="text" class="textbox" id="2" />
</TD>
</TR>
</table>
Submit : <input type = "submit" name="btHello" onclick="sum();">
</form>
</html>
Hope my example helps. I suggest using jQuery. It makes it much easier.
function foo() {
var s = [];
$(".foo").each(function() {
s.push( $(this).val() );
});
s = s.join(" ");
alert("sum = " + s);
}
$("#btHello").on("click", function() { foo(); });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<table border=2>
<tr>
<td>
<input type="text" class="foo" /input>
</td>
<td>
<input type="text" class="foo" /input>
</td>
</tr>
</table>
<button id="btHello">sum</button>
I´m to totally sure what result you want, but this should help you on your way. If its not totally what you are after, please try to explain your goal a bit more. :)

I have snippet in javascript that add/remove multiple rows within a table. I would like to implement the same thing into JQUERY. At the moment, the checkboxes does'nt work, but I would like them to work for the sake of userbility. I got no clue on jquery at moment. Would you help on the implementation.
