I need a code generator in jQuery that when clicking on the button it appears in the input text a number of 13 digits, start in number 7.
This is the code in my view:
<div class="form-group <?php echo !empty(form_error('barcode')) ? 'has-error':'';?>">
<label for="barcode">Barcode:</label>
<div class="input-group barcode">
<div class="input-group-addon">
<button class="fa fa-barcode" title="Generate Random Barcode"></button>
</div>
<input type="text" class="form-control" id="barcode" name="barcode" required value="<?php echo set_value('barcode');?>">
</div>
<?php echo form_error("barcode","<span class='help-block'>","</span>");?>
</div>
This is the input text + button:
The generated number like this:
You can do this :
$(document).on('click', '#barcode_btn', function(e){
e.preventDefault();
var val1 = Math.floor(100000 + Math.random() * 999999);
var val2 = Math.floor(10000 + Math.random() * 99999);
$('[name="barcode"]').val('7 '+val1+' '+val2);
})

There are lot of issues in the snippet you shared, you are trying to using ID in the original element and cloning it, this is a bad idea for your use case. What you can do is convert it to class, and pass the target element in cal(). by doing that you can find the element. And your label for nights is not closed properly
replace your exiting script block
<script type="text/javascript">
function GetDays(target){
var dropdt = new Date($(target).find(".drop_date").val());
var pickdt = new Date($(target).find(".pick_date").val());
return parseInt((dropdt - pickdt) / (24 * 3600 * 1000));
}
function cal(target){
console.log($(target).parent(), $(target).parent().find('numdays2'));
$(target).parent().find('.numdays2').val(GetDays($(target).parent()));
}
</script>
and replace your .personal-details html block with this
<ul class="personal-details">
<label for="roomid">RoomID</label>
<input name="roomid[]" type="text" class="stretchnights" id="roomid" readonly="readonly" value="1">
<label for="chkin">Check IN</label>
<input size="15" width="15" id="pick_date" class="pick_date" type="date" name="chkin[]" onchange="cal(this)" required/>
<label for="chkout">Check Out</label>
<input id="drop_date" type="date" name="chkout[]" class="drop_date" onchange="cal(this)" required/>
<label for="nights">Nights </label>
<input class="numdays2" type="text" id="numdays2" name="nights[]" readonly />
This should solve the problem
You are using the same id in function call for the clones.

I have a input field that is readonly that shows the user the money they have left over after spending. They first have to enter their income and in the spending field, it will show the value from the database. My problem is after calculating the money left over in javascript, the value does not show in the leftOver field. I am not sure what I am doing wrong. Here is my code:
<script type="text/javascript">
$(document).ready(function(){
$("#addRecord").hide();
$("#btnAdd").click(function(){
$("#addRecord").show();
});
});
</script>
<script type="text/javascript">
function getTotalIncome(){
var income = parseFloat(document.getElementById("income").value);
var otherIncome = parseFloat(document.getElementById("otherIncome").value);
var totalIncome = income + otherIncome;
document.getElementById("totalIncome").value = '$' + totalIncome;
}
</script>
<script type="text/javascript">
function getLeftOver(){
var totalIncome = parseFloat(document.getElementById("totalIncome").value);
var totalSpending = parseFloat(document.getElementById("totalSpending").value);
var leftOver = totalIncome - totalSpending;
document.getElementById("leftOver").value = '$' + leftOver;
}
</script>

I want to make a book catalog with JQuery to add books to a author. In the code That I have I am trying to add a author and have his books be in a array with his number only. Separated by other authors and their own arrays of books.
For example, when I press the button to add a author a input box appears so that I can add the authors name also a button to add a book that when I press that button I get an input box to add a books name.
When I press the add author again I want to be able to add another author with the same input boxes as before (adding more books to that author).
Also to add multiple books assigned to that author.
I have already done this in the pics but I get an array of everything. I want it to be separated by author.
author1 has an array of {book1, book2, book3...}
author2 has an array of {book13, book14, book15}
(i'm a beginner at JQuery)
This is the code that I have so far:

Please try this code and include jquery min js :
<div class="my-form">
<form role="form" method="post">
<p class="all_fields">
<div id="commonPart" class="commonPart">
<label for="author1">Author <span class="author-number"></span></label>
<input type="text" name="author" value="" id="author1" />

<script> function AddCustomMOre(){
$(".all_fields ").append('<div id="commonPart" class="commonPart"><label for="author1">Author <span class="author-number"></span></label> <input type="text" name="author" value="" id="author1" /> <br/> <div><label for="author1">book <span class="author-number"></span></label> <input type="text" class="bookName" name="authBook[]"/></div> Remove</div>');

i need add fields dynamically in my view form. i have a script function for that.. but i don't know how to include in that script into codeIgniter.
my controller -
class uploadfile extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->helper('url');}
//index function
function index()
{
//load file upload form
$this->load->view('upload_file_view');}}
my view -
<script type="text/javascript" src="<?php echo base_url("assets/js/myscript.js");?>" ></script>
</head>
<body>
<label for="doc" class=" control-label">SUPPORT DOCUMENT</label>
<div class="multi-field-wrapper ">
<div class="multi-fields">
<div class="multi-field">
<input id="doc" type="text" class="form-control" name="attachment[]">
</div> </div>
<button type="button" class="add-field">Add field</button> </div>
and my script path - C:\xampp\htdocs\samplecod\assets\js
i found a easy way to add multiple fields in view page
`<div class="form-group">
<div class="row colbox">
<div class="col-sm-offset-2 col-lg-8 col-sm-8 text-left">Description</div>
<div class="field_wrapper">
<input type="textarea" name="descrip[]" value="" size="35px" /><input type="text" name="voucher_no[]" value="" size="7px"/><input type="text" name="price[]" value=""size="7px"/>
<img src="<?php echo base_url('images/add-icon.png'); ?>"/>
</div></div></div>`
for this form this is the script:
<script type="text/javascript">
$(document).ready(function(){
var maxField = 20; //Input fields increment limitation
var addButton = $('.add_button'); //Add button selector
var wrapper = $('.field_wrapper'); //Input field wrapper
var fieldHTML = '<div><input type="text" name="descrip[]" value="" size="35px"/><input type="text" name="voucher_no[]" value="" size="7px"/><input type="text" name="price[]" value="" size="7px"/><img src="<?php echo base_url('images/remove-icon.png'); ?>"/></div>'; //New input field html
var x = 1; //Initial field counter is 1
$(addButton).click(function(){ //Once add button is clicked
if(x < maxField){ //Check maximum number of input fields
x++; //Increment field counter
$(wrapper).append(fieldHTML); // Add field html
}
});
$(wrapper).on('click', '.remove_button', function(e){ //Once remove button is clicked
e.preventDefault();
$(this).parent('div').remove(); //Remove field html
x--; //Decrement field counter
});
});
</script>
