Save input data to table on same page? HTML and Javascript - javascript

I am brand new to JavaScript and HTML, and am trying to make a rehersal booking app which collects the info needed and displays it in a table on the same page.
I have been trying for hours on end to get it to work with various methods and I feel like it's just getting worse. I have probably made some silly mistakes but I cant seem to work out what I need to change to make it work.
Here is my HTML:

DESIGN: Dropdown+Label+Button and Repeating row wise

I have a design related question.
I have a bill to add product. One product is added per line.
One Product added per line image
When I add a product, I also display its warranty in the Warranty column:
Selected product shows warranty in Warranty Column
But when I add any other product, I cannot display its Warranty.
Cannot Display Warranty in subsequent products
My HTML where dropdown options are coming dynamically:
<tbody style="border: 1px solid rgba(0,0,0,0.35); height: 34px; line-height: 34px;">
<tr class="text-center">
<td>
<select id="myDropdown" name="bill_product[]" onChange="dropdownTip(this.value)">
<option disabled selected value="">Select Product</option>
<option id="1" value="31/01/2020">Product #1</option>
<option id="2" value="31/01/2030">Product #2</option>
<option id="3" value="31/01/2040">Product #3</option>
</select>
</td>
<td>
<input name="txtbox" type="text" id="txtbox" />
</td>
<td>
<button type="button" class="btn btn-danger btn-xs disabled">
<i class="fa fa-times"></i>
</button>
</td>
</tr>
</tbody>
My JS for adding row to bill:
$(document).ready(function () {
var counter = 0;
$("#addrow").on("click", function () {
var newRow = $("<tr class='text-center'>");
var cols = "";
cols += '<td><select name="bill_product[]"><option disabled selected value="">Select Product</option><cms:pages masterpage="product.php"><option value="<cms:show k_page_id />"><cms:show k_page_title /></option></cms:pages></select></td>';
cols += '<td><input type="text" id="txtbox" name="txtbox" /></td>';
cols += '<td><button type="button" class="ibtnDel btn btn-danger btn-xs"><i class="fa fa-times"></i></button></td>';
newRow.append(cols);
$("table.order-list").append(newRow);
counter++;
});
$("table.order-list").on("click", ".ibtnDel", function (event) {
$(this).closest("tr").remove();
counter -= 1
});
});
My Code to display the warranty end date:
$(document).ready(function() {
$("#myDropdown").change(function() {
var selectedValue = $(this).val();
$("#txtbox").val(selectedValue);
});
});
ISSUE: I am unable to display the value of the warranty date on any product after the first one.
Please help.
P.S.: I am using CouchCMS to dynamically bring my values to the option tag of select.
Here's the solution I propose, I get rid off not-native JS by the way, it allows it to fit with any solution :
<tbody style="border: 1px solid rgba(0,0,0,0.35); height: 34px; line-height: 34px;">
<tr class="text-center">
<td>
<select id="myDropdown" name="bill_product[]" onChange="dropdownTip(this.value)">
<option disabled selected value="">Select Product</option>
<option id="1" value="31/01/2020">Product #1</option>
<option id="2" value="31/01/2030">Product #2</option>
<option id="3" value="31/01/2040">Product #3</option>
</select>
</td>
<td>
<input name="txtbox" type="text" id="txtbox" />
</td>
<td>
<button type="button" class="btn btn-danger btn-xs disabled">
Delete
</button>
</td>
</tr>
</tbody>
// Line removal
let delBtns = document.querySelectorAll(".del-btn");
[].forEach.call(delBtns, function(delBtn){
delBtn.addEventListener('click', function(event){
let line = event.target.dataset.line;
let lineToRemove = document.querySelector("#line-"+line);
lineToRemove.remove();
})
});
// Input update
let productDropDowns = document.querySelectorAll("select");
[].forEach.call(productDropDowns, function(dropDown){
dropDown.addEventListener('change', function(event){
let line = event.target.dataset.line;
document.querySelector('#line-'+line+' input').value = event.target.value;
})
});
// New line button
let count = 0;
let newLineButton = document.querySelector("#newLineTrigger");

count++;
let tableBody = document.querySelector('tbody');

I don't see the triggerring element '#addrow' which adds the row. Could you update the fiddle to include this button, please?
The ids for all warranty input field is same, which is "txtbox". You can use the counter variable to have separate ids for all warranty fields.

Using just Javascript, how can I prevent a disabled form element from output?

I am trying to take my form which outputs to a text area on the same page and have it only show any enabled fields. You can see it at my JSFiddle here, Right now, when you click the "Combine" button it outputs all 4 categories even though two are disabled by default.
So it will output:
Optional Detail:
Default Detail:
Optional Selection:
Default Selection:
But I want it to look like this if the details toggles are unchecked:
Default Detail:
Default Selection:
Here's my script:
function convertForm() {
var detailToggle = document.getElementById("detailToggle").value;
var basicDetail = document.getElementById("basicDetail").value;
var selectOne = document.getElementById("selectOne").value;
var selectTwo = document.getElementById("selectTwo").value;
var output = "";
output += "Optional Detail: " + detailToggle + "\n";
output += "Default Detail: " + basicDetail + "\n";
output += "Optional Selection: " + selectOne + "\n";
output += "Default Selection: " + selectTwo + "";
document.getElementById("output3").value = output;
}
function toggle(checkboxID, toggleID) {
var checkbox = document.getElementById(checkboxID);
var toggle = document.getElementById(toggleID);
updateToggle = checkbox.checked ? toggle.disabled=false :
toggle.disabled=true;
}
function ResetForm() {
document.getElementById("detailToggle").disabled = true;
document.getElementById("selectOne").disabled = true;
}
And the HTML:
<table width="100%" height=" " border="0"><tr>
<td width=550 valign=top>
<form name="Form3" onsubmit="return false;" action="">
Toggle detail:
<input type="checkbox" id="ChecktoggleDetail" class="formArea"
name="Toggledetail" onClick="toggle('ChecktoggleDetail', 'detailToggle')">
<input type="text" class="formArea" name="details"
id="detailToggle" placeholder="Toggle field" disabled required>
<br>
Detail:
<br>
<input type="text" class="formArea" name="Basicdetail" id="basicDetail"
placeholder="Some detail" maxlength="25" required>
<br>
Selection 1:
<input type="checkbox" id="CheckselectOne" class="formArea"
name="detailsgiven" onClick="toggle('CheckselectOne', 'selectOne')">
<br>
<select type="drop" class="formArea" name="Selectone" id="selectOne"
disabled required>
<option value="" disabled selected>...</option>
<option value="Option One">Option 1</option>
<option value="Option Two">Option 2</option>
</select>
<br>
Selection 2:
<br>
<select type="drop" class="formArea" name="Selecttwo" id="selectTwo"
required>
<option value="" disabled selected>...</option>
<option value="Option One">Option 1</option>
<option value="Option two">Option 2</option>
</select>
<br>
</td>
<td valign="top">
<table border="0" height="200" ><tr><td valign="top" height=200>
<textarea type="textarea" class="formArea" name="form3output" id="output3"
onclick="this.focus();this.select()" cols="70" rows="10" placeholder=""
required></textarea><br>
</td></tr>
<tr><td valign=top>
<div class="btn-group">
<button value="Combine" onclick="convertForm()"
id="combine3">Combine</button>
</div>
<br>
<div class="btn-group2">
<button type="reset" value="Reset form" onclick="ResetForm();">Reset
form</button> <br>
</div>
</form>
</td></tr></table>
I am still new to Javascript, I am guessing there is some variable to insert, but am not sure what it is. Any help is appreciated.
You May Try For This:
Here I just check the disabled property of the element, if element is not disabled then i added text to output,
function convertForm() {
var detailToggle = document.getElementById("detailToggle").value;
var basicDetail = document.getElementById("basicDetail").value;
var selectOne = document.getElementById("selectOne").value;
var selectTwo = document.getElementById("selectTwo").value;
debugger;
var output = "";
if(!document.getElementById("detailToggle").disabled){
output += "Optional Detail: " + detailToggle + "\n";
}
if(!document.getElementById("basicDetail").disabled){
output += "Default Detail: " + basicDetail + "\n";
}
if(!document.getElementById("selectOne").disabled){
output += "Optional Selection: " + selectOne + "\n";
}
if(!document.getElementById("selectTwo").disabled){
output += "Default Selection: " + selectTwo + "";
}
document.getElementById("output3").value = output;
}
function toggle(checkboxID, toggleID) {
var checkbox = document.getElementById(checkboxID);
var toggle = document.getElementById(toggleID);
updateToggle = checkbox.checked ? toggle.disabled=false : toggle.disabled=true;
}
function ResetForm() {
document.getElementById("detailToggle").disabled = true;
document.getElementById("selectOne").disabled = true;
}

Use below javascript to check element is disabled first then append in variable
Check updated fiddle : https://jsfiddle.net/yogesh078/66qpfyhh/1/
function convertForm() {
var detailToggle = document.getElementById("detailToggle");
var basicDetail = document.getElementById("basicDetail");
var selectOne = document.getElementById("selectOne");
var selectTwo = document.getElementById("selectTwo");
var output = "";
if (!detailToggle.disabled) {
output += "Optional Detail: " + detailToggle.value + "\n";
}
if (!basicDetail.disabled) {
output += "Default Detail: " + basicDetail.value + "\n";
}
if (!selectOne.disabled) {
output += "Optional Selection: " + selectOne.value + "\n";
}
if (!selectTwo.disabled) {
output += "Default Selection: " + selectTwo.value + "";
}
document.getElementById("output3").value = output;
}
function toggle(checkboxID, toggleID) {
var checkbox = document.getElementById(checkboxID);
var toggle = document.getElementById(toggleID);
updateToggle = checkbox.checked ? toggle.disabled = false : toggle.disabled = true;
}
function ResetForm() {
document.getElementById("detailToggle").disabled = true;
document.getElementById("selectOne").disabled = true;
}
This code snippet can solve your problem.
function convertForm() {
var detailToggle = document.getElementById("detailToggle").value;
var basicDetail = document.getElementById("basicDetail").value;
var selectOne = document.getElementById("selectOne").value;
var selectTwo = document.getElementById("selectTwo").value;
if(document.getElementById("detailToggle").disabled)
detailToggle='';
if(document.getElementById("selectOne").disabled)
selectOne='';
var output = "";
output += "Optional Detail: " + detailToggle + "\n";
output += "Default Detail: " + basicDetail + "\n";
output += "Optional Selection: " + selectOne + "\n";
output += "Default Selection: " + selectTwo + "";
document.getElementById("output3").value = output;
}
function toggle(checkboxID, toggleID) {
var checkbox = document.getElementById(checkboxID);
var toggle = document.getElementById(toggleID);
updateToggle = checkbox.checked ? toggle.disabled=false : toggle.disabled=true;
}
function ResetForm() {
document.getElementById("detailToggle").disabled = true;

Table Add More Row using javascript

I am adding dynamic row to table. But when adding new row, I want to replace some string on new row. But it is not working.
<table id="testTable">
<tr id="row_1">
<td>
<select onchange="changeCustomCategory(this.value,'1');" id="_cid" name="_cid[0]" >
<option value="">--Select Product--</option>
<option value="test">Test</option>
</select>
<input type="text" onchange="_doVariation(1);" value="1" id="_qty" name="_qty[0]"/>
<input type="text" class="textfield" value="0.00" id="item1_total" name="item1_total" readonly>
</td>
</tr>
</table>
<input type="hidden" value="1" id="total_row">
<input type="button" onclick="addRow()" value="Add Row">
This is my HTML code.
function addRow(){
var total_row = document.getElementById("total_row").value;
var _previousId = parseInt(total_row);
var new_id = parseInt(total_row) + 1;
document.getElementById("total_row").value = new_id;
var table = document.getElementById("testTable");
jQuery("#"+ table.rows[0].id).clone().appendTo("#testTable");
var totalTableRow = table.rows.length;
var currentRow = table.rows[totalTableRow-1];
currentRow.id = "row_"+new_id;
currentRow.innerHTML = currentRow.innerHTML.replace('_cid\['+ new_id-1 +'\]','_cid['+new_id+']');
currentRow.innerHTML = currentRow.innerHTML.replace(new RegExp("changeCustomCategory(this.value,'"+_previousId+"')","g"),'changeCustomCategory(this.value,'+new_id+')');
currentRow.innerHTML = currentRow.innerHTML.replace('_doVariation('+_previousId+')','_doVariation('+new_id+')');
}
You can perform your changes as the following:
//....
var newRow = jQuery("#"+ table.rows[0].id).clone().appendTo("#testTable");
//Change1
newRow.attr('name', '_cid['+new_id+']');
//Change2:
newRow.find('select').removeAttr('onchange').change(function() {
changeCustomCategory(this.value, new_id);
});
//Change3:
newRow.find('input:first').removeAttr('onchange').change(function() {
_doVariation(new_id);
});
//....
Demo: https://jsfiddle.net/4c0v2d50/
I would suggest sticking to jquery functions and not mixing too much with plain javascript. It makes it easier to code and follow.
I believe this is what your trying to do:
change HTML
id="_cid" name="_cid[0]"//change in select to
class="_cid" name="_cid[]"//_cid[] will automatically increment
id="_qty" name="_qty[0]"//same in input
class="_qty" name="_qty[]"
//you should also change
id="item1_total"
class="item1_total"
Javascript
function addRow(){
var new_id = $("#total_row").val() + 1;
$("#total_row").val(new_id);
var $currentRow = $("#testTable tr:first").clone();
$("#testTable").append(currentRow);
$currentRow.attr(id,"row_"+new_id);
$currentRow.find('select').attr('onclick',"changeCustomCategory(this.value,'"+new_id+"')");
$currentRow.find('._qty').attr('onchange','_doVariation('+new_id+')');
}
Removed the inline binding and bound to the element in the logic. Started changing the first thing you were trying to do with a regex. You can see how you like this approach.
jQuery(function($) {
//cache selectors
var $total_row = $("#total_row"),
$table = $("#testTable");
$(".addRow").on('click', function addRow() {
var total_row = $total_row.val(),
_previousId = parseInt(total_row),
new_id = _previousId + 1;
$total_row.val(new_id);
var $new_row = $table.find("tr").eq(0).clone();
$new_row.attr("id", "row_"+ new_id);
$new_row.find("select").attr("name", "_cid["+ (new_id - 1) +"]");
$table.append($new_row);
// currentRow.innerHTML = currentRow.innerHTML.replace('_cid\[' + new_id - 1 + '\]', '_cid[' + new_id + ']');
// currentRow.innerHTML = currentRow.innerHTML.replace(new RegExp("changeCustomCategory(this.value,'" + _previousId + "')", "g"), 'changeCustomCategory(this.value,' + new_id + ')');
// currentRow.innerHTML = currentRow.innerHTML.replace('_doVariation(' + _previousId + ')', '_doVariation(' + new_id + ')');
});
});

var _previousId = parseInt(total_row);

$(currentRow).find('#_cid').attr('onclick',"changeCustomCategory(this.value,'"+new_id+"')");

Working fiddle.
The id attribute should be unique so you could replace the duplicate ones by class attributen example :
<select class="_cid" name="_cid[0]" >
<input type="text" value="1" class="_qty" name="_qty[0]"/>
Better if you could avoid the inline-event onclick() and the overriding of parameters in every clone and define a general event one time and it will work for all the element, example :
$('body').on('change','._cid', function(){
//You code here
})
You don't need to increment the names you have just to leave the array signs empty [] and it will be incremented automatically, example :
<select class="_cid" name="_cid[]" >
<input type="text" value="1" class="_qty" name="_qty[]"/>
Hope this helps.
$(function(){
$('body').on('change','._cid', function(){
var id_number = $(this).parents('tr').attr('id').split('_')[1];
changeCustomCategory($(this).val(),id_number);
})
$('body').on('change','._qty', function(){
var id_number = $(this).parents('tr').attr('id').split('_')[1];
_doVariation(id_number);
})

Javascript form calculation errors

Im getting uncaught type error for estimateCost, also im having issues with how to double the price with spouse. I'm suppose to have an alert window that displays the estimate cost based on selections made from city, number of days, and other options. TY!

On the button input with the onClick="estimateCost()" code, remove the id="estimateCost". It's causing the error for some reason. You should really be using an onClick listener though instead of an inline onclick:
Inline onclick JavaScript variable
For the total with spouse, you might want to rework it to something like this where you pass the pre-spouse price into the chksSpouse function and use it's return as the total price.
//chksSpouse() finds the candles price based on a check box selection
function chksSpouse(totalPrice) {
var chkSpouse = 0;
//Get a reference to the form id="form1"
var theForm = document.forms["form1"];
//Get a reference to the checkbox id="chkSpouse"
var includeSpouse = theForm.elements["chkSpouse"];
//If they checked the box set Total 2x
if (includeSpouse.checked == true) {
totalPrice = totalPrice * 2;
}
//finally we return the firstClass
return totalPrice;
}
function estimateCost() {
//Here we get the estimate price by calling our function
//Each function returns a number so by calling them we add the values they return together
var preSpouseTotal = getCityPrice() + getDayPrice() + chksFirst();
var totalPrice = chksSpouse(preSpouseTotal);
alert(totalPrice);
}

The result after adding 2 function is undefined

I am trying to add two functions calculate1() and calculate2(). Both functions are taking values from function populate(). Is the code wrong? Once I enter an amount on both functions, the result is total amount undefined.
<form>
Car:
<select id="slct1" name="slct1" onchange="populate('slct1','slct2')">
<option value=""></option>
<option value="Fiat">Fiat</option>
<option value="Dodge">Dodge</option>
<option value="Ford">Ford</option>
</select>
Type of Car:
<select id="slct2" name="slct2">
</select>
<label> Amount <input style="width:10%" type="number" name="amount1" id="amount1" onkeyup="result()"/> (g) </label>
<label> Total <input style="width:10%" type="number" name="answer1" id="answer1"/></label>
<input type="reset" name="Reset" value="Reset" onclick="rstFunction()"/>

var t = total1 + total2;
function result() {
document.getElementById('ansCAL').value = calculate1() + calculate2();
}
function populate(select1, select2)
{
var Brand1 = document.getElementById(select1);
var Brand2 = document.getElementById(select2);
Brand2.innerHTML = "";
if(Brand1.value == "Fiat")
{

}
function calculate1() {

function resetFunctions() {
//using the array forEach method on the form
Array.prototype.forEach.call(document.forms,function(el,idx,array){
//the method parameters are element, index and the array
// we loop through all the forms and invoking reset()
el.reset();
});
result();
}
function rstFunction()
{
document.getElementById("ansCAL").innerHTML = "<br>Total amount" + result().value;

</script>
The answer was to increase the total in every calculate function. Example (total + total1). Removed the variable t and declared the totals in the printout section.
