How to update price based on number of quantity using jquery - javascript

I want to create a shopping cart where a client select an item from the autocomplete search automatically added to cart.and based on the number of quantity price can be updated. I have added to the cart successfully but I couldn't update the price dynamically.
Can anyone point me out what's the error with the existing code:
$('#searchName').autocomplete({
source: '{!! asset('nameAutocomplete') !!}',
select:function(suggestion,ui){
event.preventDefault();
var $tbody = $('#example tbody');
$tbody.append('<tr><td class="id">' + ui.item.id +
'</td><td class="name">' + ui.item.value +
'</td><td class="price" id="price">' + ui.item.price +
'</td><td><input type="text" id="quantity" value="1"/></td><td><input type="text" id="total" readonly value="'+ui.item.price+'" class="readonly"/></td></tr>');
$('#quantity').on('keyup',function(){
var tot = ui.item.price * this.value;
$('#total').val(tot);
});
}
});
Here is the table part code :
<table class="table table-striped table-bordered" id="example">
<thead>
<tr>
<td>ID</td>
<td>Name</td>
<td>Price</td>
<td>Quantity</td>
<td>Total</td>
</tr>
</thead>
<tbody>
</tbody>
</table>
Error I'm getting :

Check with following code,I added little bit to #Mayank code,
var $tbody = $('#example tbody');
$tbody.append('<tr><td class="id">' + ui.item.id +
'</td><td class="name">' + ui.item.value +
'</td><td class="price">' + ui.item.price +
'</td><td><input type="text" class="quantity" value="1"/></td><td><input type="text" class="total" readonly value="'+ui.item.price+'" class="readonly"/></td></tr>');
$('.quantity').on('keyup',function(){
//Corrected part
var tot = $(this).parent().prev().html() * this.value;
//var tot = ui.item.price * this.value;
//Assume that you are getting correct value to tot variable
$(this).parent().next().find('.total').val(tot);
});

Make following changes in code like:
var $tbody = $('#example tbody');
$tbody.append('<tr><td class="id">' + ui.item.id +
'</td><td class="name">' + ui.item.value +
'</td><td class="price">' + ui.item.price +
'</td><td><input type="text" class="quantity" value="1"/></td><td><input type="text" class="total" readonly value="'+ui.item.price+'" class="readonly"/></td></tr>');
// Use class in place of id, as you cannot work with id for multiple occurance of same html
$('.quantity').on('keyup',function(){
var tot = ui.item.price * this.value;
$(this).find('.total').val(tot); // Use DOM traverse to get the next <input type="text" /> and put new total value to it
});

vuejs creating onclick event from js method DOM

In my Vue CLI component, I'm populating a row table dynamically
i.e. inside my methods:
add_row() {
var new_name = document.getElementById("new_name").value;
var new_country = document.getElementById("new_country").value;
var new_age = document.getElementById("new_age").value;
var table = document.getElementById("data_table");
var table_len = table.rows.length - 1;
table.insertRow(table_len).outerHTML =
"<tr id='row" +
table_len +
"'><td id='name_row" +
table_len +
"'>" +
new_name +
"</td><td id='country_row" +
table_len +
"'>" +
new_country +
"</td><td id='age_row" +
table_len +
"'>" +
new_age +
"</td><td><input type='button' value='Delete' class='delete' #click=\"delete_row(" +
table_len +
')"></td></tr>';
document.getElementById("new_name").value = "";
document.getElementById("new_country").value = "";
document.getElementById("new_age").value = "";
}
This is the HTML part of the component:
<table
align="center"
cellspacing="2"
cellpadding="5"
id="data_table"
border="1"
>
<tr>
<th>Name</th>
<th>Country</th>
<th>Age</th>
</tr>
<tr id="row1">
<td id="name_row1">Ankit</td>
<td id="country_row1">India</td>
<td id="age_row1">20</td>
<td>
<input
type="button"
value="Delete"
class="delete"
#click="delete_row('1')"
/>
</td>
</tr>
<tr>
<td><input type="text" id="new_name" /></td>
<td><input type="text" id="new_country" /></td>
<td><input type="text" id="new_age" /></td>
<td>
<input
type="button"
class="add"
#click="add_row()"
value="Add Row"
/>
</td>
</tr>
</table>
Notice in my add_row function, when populating the row, I append a delete button tag and in it, pass the method delete_row. Clicking on this delete button should fire the method as shown below:
in my methods:
delete_row(no) {
document.getElementById("row" + no + "").outerHTML = "";
},
But the method is not being triggered from the delete_row function. I've confirmed that the rows are working well since my button for adding that row the add_row function fires. So my thinking is since I call the delete_row function from a dynamically created, there's perhaps something extra that I need to pass to my code to trigger this method?

add dynamic order to add remove html input field

i have this code for add/remove dynamic input:

this code work true for me but how do can i add dynamic order(from 1 to ...) for each row(td). my mean add order input from number 1 and add +1 number from last order number.
demo is here
update: (my need)
You need to just modify the JS code logic. The below example shows the use of variable count and its usage.
Here, the variable count is declared as 1 initially and as per the "Add" click the count value has been incremented by 1. Same way the count is been decremented by 1 when we are deleting/removing the the "tr" column.
$(function () {
var count = 1;
$("#btnAdd").bind("click", function () {
var div = $("<tr />");
div.html(GetDynamicTextBox("", count));
$("#TextBoxContainer").append(div);
count++;
});
$("body").on("click", ".remove", function () {
$(this).closest("tr").remove();
count--;
});
});
The click function will have one more argument count which is used for the rendering/displaying of the count value in the order field.
function GetDynamicTextBox(value, count) {
var number = Math.random();
return '<td id="' + number + '">
<input name = "DynamicTextBox" type="text" value = "' + value + '" class="form-control" />
</td>' + '
<td>
<select name="" class="form-control">
<option> Select</option>
<option> Male</option>
<option> Female</option>
</select>
</td>' + '
<td>
<input name = "DynamicTextBox" type="radio" value = "' + value + '" />
</td>' + '
<td>
<input name = "DynamicTextBox" type="checkbox" value = "' + value + '" />
</td>'+'
<td>
<input name = "order" type="number" value = "' + count + '" /></td>' + '
<td>
<button type="button" class="btn btn-danger remove"><i class="glyphicon glyphicon-remove-sign"></i></button>
</td>'
}
The above code works when we are removing the row from the last column.
If you are removing in-between the row from the list of tr tags you will find the order columns values are not arranged properly.
The below code is used for the removing the tr tag in-between the row and as well as the from the last tr tag. This code will be flexible for removing the tr row from anywhere in the list as well as updating the order row in the incremental way.
$("body").on("click", ".remove", function () {
var deleteElement = $(this).closest("tr");
var countOfDeleteElement = $(deleteElement).find("#order").val();
var lastElementCount = count - 1;
if (countOfDeleteElement !== lastElementCount) {
// It will come inside this if block when we are removing inbetween element.
var remainingElements = deleteElement.nextAll('tr'); // get all the below elemnts from the removing element.
// updating all remainingElements value of the order column
remainingElements.each((i, ele) => {
$(ele).find("#order").val(countOfDeleteElement);
countOfDeleteElement++;
})
}
deleteElement.remove();
count--;
});

how to get user entered data and ID's in dynamically added table rows?

How can I get dynamically added rows id's and user entered data? I have created a dynamic table but I don't know how to get the values and dynamically generated id's. Can anyone please help me?
$('body').on('change', '[data-action="sumDebit"]', function() { //Attach an event to body that binds to all tags that has the [data-action="sumDebit"] attribute. This will make sure all over dynamically added rows will have the trigger without us having to readd after ever new row.
var total = 0;
$('[data-action="sumDebit"]').each(function(_i, e) { //Get all tags with [data-action="sumDebit"]
var val = parseFloat(e.value); //Get int value from string
if (!isNaN(val)) //Make sure input was parsable. If not, result come back as NaN
total += val;
});
$('#totaldbt').val(total); //Update value to total

FIDDLE Here..
What do you mean by ids?? on what action you would want user data and ids of dynamically created rows.
Everything is there. You have jsrow enter code hereclass for each tr created. Fetch all tr and then fetch each input value as you have distinct class for each input.
var rows = $('#cashTable').find('tr.jsrow'); // get all rows.
Then iterate rows as per your need. i am writing directly lets say want to get all ids of row 2. Find all inputs under that row as below and then get id attribute.
var inputs = $(rows[0]).find('input'); // all inputs. same way all select as well
// iterate all inputs and grab ID attribute
for(let i =0 ; i< inputs.length; i++ ) {
var attr = inputs[i].getAttribute('id');
console.log(attr); // id attribute
console.log(inputs[i].value); // value
}
You can get user input by referring to the column and row inside a table
var table = document.getElementById("cashTable"), sumVal = 0;
for(var i = 1; i < table.rows.length; i++)
{
sumVal = sumVal + parseFloat(table.rows[i].cells[5].innerHTML);
//here cells is referred to the cell number you want the value if you want the value of all cells of a row then loop through the cells of a row
}
alert(sumVal);
console.log(sumVal);

How to add dynamic change input value

I have problem. I use jquery to make dynamic input in php like this:
$(document).ready(function() {
var count = 0;
$("#add_btn").click(function(){
count += 1;
$('#container').append(
'<tr class="records">'
+ '<td ><div id="'+count+'">' + count + '</div></td>'
+ '<td><select class="form-control form-control-sm" name="site' + count + '" required><option value="">Input Item</option><option value="canon">canon</option><option value="nikon">nikon</option><option value="fuji">fuji</option></select></td>'
+ '<td><input name="codeitem' + count + '" type="text"></td>'
+ '<td><a class="remove_item" href="#" >Delete</a>'
+ '<input id="rows_' + count + '" name="rows[]" value="'+ count +'" type="hidden"></td>'
+ '</tr>'
);
});
$(".remove_item").live('click', function (ev) {
if (ev.type == 'click') {
$(this).parents(".records").fadeOut();
$(this).parents(".records").remove();
}
});
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form id="id_form" action="save.php" method="post">
<table>
<tr>
<td>
<input type="button" name="add_btn" value="Add" id="add_btn">
</td>
</tr>
<tr>
<td>No</td>
<td>Item</td>
<td>Code Item</td>
<td> </td>
</tr>
<tbody id="container">
<!-- nanti rows nya muncul di sini -->
</tbody>
<tr>
<td>
<input type="submit" name=submit value="Save">
</td>
<td> </td>
<td> </td>
<td> </td>
</tr>
</table>
</form>
Condition: If I chose canon in combo select menu, then at input codeitem show code of the item (in another case, I use PHP to get codeitem from SQL table.
At first row input field, that was success.. but, if I want add more input field with click 'add button' to entry another item (at second row input field), why first input codeitem change code item, not input codeitem at second row?
How can I input dynamic item with that condition?
If you are not working on a legacy code base then it is batter to use latest version of Jquery.
'<td ><div id="'+count+'">' + count + '</div></td>' , you can't use same id in multiple time, so change it to class.
'<td><input name="codeitem' + count + '" type="text"></td>' ,input field name should be fixed in order to process it in your php script after form submit but as you need to get multiple value make it an array codeitem[]
what is the use of rows[] input field?
To input codeitem dynamically on change combo select menu, you have to use "Ajax" to get the 'codeitem' value of the selected combo menu from your database.
Check this jsfiddle .
$(document).ready(function() {
$("#add_btn").click(function(){
let count = $('tr.records').length+1;
$('#container').append(
'<tr class="records">'
+ '<td ><div class="count">' + count + '</div></td>'
+ '<td><select class="site form-control form-control-sm" name="site[]" required><option value="">Input Item</option><option value="canon">canon</option><option value="nikon">nikon</option><option value="fuji">fuji</option></select></td>'
+ '<td><input class="codeitem" name="codeitem[]" type="text"></td>'
+ '<td><a class="remove_item" href="#" >Delete</a>'
+ '<input class="rows" name="rows[]" value="'+ count +'" type="hidden"></td>'
+ '</tr>'
);
});
$(document).on('click',".remove_item", function (ev) {
$(this).parents(".records").fadeOut();
$(this).parents(".records").remove();
//Re-arrange the Row Serial No
$('tr.records div.count').each(function(index) {
$(this).text(index+1)
});
});
$(document).on('change',".site", function (ev) {
let site = $(this).val();
let current = $(this).parents(".records");
if(site!=''){
//make an ajax call to get the corresponding CodeItem of the selected site
/* $.ajax({
url: "/yoururl",
data:{"id":site},
success: function(result){
$(current).find('.codeitem').val(result);
}
}); */
}else{
$(current).find('.codeitem').val('');
}
});
})

How to display dropdown list with values in the datatable while performing inline editing?

I need to display a dropdownlist in a particular cell while performing inline editing and need to load the values in the dropdownlist from the datatbase. I know how to load the values in the dropdownlist outside the datatable. Is this the same process while it is inside the datatable?.
Please give me some ideas to perform this task?
This is my code, where the row that is clicked will have the textbox and the dropdownlist (without any values)
var table = $('#jsontable').DataTable();
$('#jsontable').DataTable().column(0).visible(false);
$('#jsontable').DataTable().column(3).visible(false);
var nEditing = null;
$('#jsontable tbody').on('dblclick', 'tr', function () {
var nRow = $('#jsontable').dataTable().fnGetNodes(this);
d = $('#jsontable').DataTable().row(this).data();
editRow(table, nRow);
nEditing = nRow;
});
function editRow(table, nRow){
var jqTds = $('>td', nRow);
jqTds[0].innerHTML = '<div class="col-sm-3"><select class="form-control" value: "' + d[1] + '" optionsCaption: "All" id="channel"></select></div>';
jqTds[1].innerHTML = '<input type="text" value="' + d[2] + '">';
jqTds[2].innerHTML = '<input type="text" value="' + d[4] + '">';
jqTds[3].innerHTML = ' <div class="col-sm-6" id="dt-container" data-bind="validationElement: locationEffcetivefromdate"><div class="input-append input-group date"> <input type="text" value="' + d[5] + '"><span class="input-group-addon"><i class="fa fa-calendar"></i></span></div></div>';
}
This is my html code for the table,
<div id="locationtable" class="ibox-content">
<table id="jsontable" class="table table-striped table-bordered table-hover dataTables-example" style="width:100%">
<thead>
<tr>
<th style="visibility:hidden">ID</th>
<th>Name</th>
<th>Age</th>
<th style="visibility:hidden">Address</th>
<th>Effective From</th>
<th>Effective To</th>
</tr>
</thead>
</table>
</div>
You could use something like below:
jqTds[1].innerHTML = '<select type="text" class="form-control input-small">' +
'<option value="' + aData[1] + '">' + aData[1] + '</option>' +
'<option value="contains">Contains</option>' +
'<option value="starts">Starts with</option>' +
'<option value="postal">Postal Radius</option>' +
'</select>';
