JavaScript sending data back to same window using callback

I have a opened window called "http://192.168.17.109/report3_test/post-data" shown below.
Onclick Launch button I am passing textbox id and callback function here is the html and jquery function
HTML
<form id="report">
<div class="form-group">
<center><label for="post-data"><h3>Reporting Data</h3></label></center>
<textarea class="form-control" rows="20" id="post-data" name="post-data"></textarea>
</div>
<div class="form-group">
<div class="col-sm-6"><button type="submit" class="btn btn-primary btn-block" name="launch" id="launch" onclick="invoke_reporting(document.getElementById('post-data'),callback)">Launch</button>
</div>
</div>
</form>
JavaScript
function invoke_reporting(textdata,callback) {
window.open("http://192.168.17.109/report3_test/templates/ct-head");
if (callback && typeof(callback) === "function") {
callback(textdata,newwindow);
}
}
Here I am opening a this new window on click launch and it shown below http://192.168.17.109/report3_test/templates/ct-head
Onclick copy to clipboard button I want to send data back to already opened window shown on top that is "http://192.168.17.109/report3_test/post-data" and here is my callback method .
function callback(finaldata){
var arr = $.parseHTML(finaldata);
v
Window.onload = function(){
var test_data = "";
for(var i=0; i<finaldata.length;i++)
{
if(i == 0){
var first_element = 'REPORT TITLE:' + '<br/>' + finaldata[0] + '<br/>' + '<br/>';
test_data += first_element.replace(/<br.*?>/g, '\n');
}else if(i == 1){
var second_element = 'FINDINGS:' + '<br/>' + finaldata[1] + '<br/>' + '<br/>';
test_data += second_element.replace(/<br.*?>/g, '\n');
}else{
var final_element = 'IMPRESSION:' + '<br/>' + finaldata[2];
test_data += final_element.replace(/<br.*?>/g, '\n');
}
}
newWindow.document.getElementById('post-data').value = test_data;
};
}
Any help would be appreciated.

how to serialize a form under specific conditions

Taka a look at this fiddle here this is a form where a business user enters the offered services.I sent the data with ajax and by serializing the form.
Click edit and add(plus sign) a service...in the example an input is added where it's name attribute value is of this **form= form[5]...**contrast with this with the form of the name attribute value in the other inputs...only the newly added services have the name attribute like this and the reason for that is to serialize only these...and not the others already present in the DOM/stored in the DB.
And now my problem:
Imagine that the user goes to edit the already registered services(or that he goes to edit them and add a new one)...at this case the already registered services wont'be serialized cause of the form the name attribute value has...(and the reason for this is explained above).
What can I do in this case?Sometimes I must serialize only part of a form and sometimes whole of the form.If all the inputs have name attribute value of form[1....] then along with the newly added input...already registered services will be serialized again.
Thanks for listening.
Code follows(you can see it in the fiddle too)
$('.editservices').click(function() {
//console.log(('.wrapper_servp').length);
originals_ser_input_lgth = $('.services').length;
var originals = [];
$('.show_price')
// fetch only those sections that have a sub-element with the .value
class
.filter((i, e) => $('.value', e).length === 1)

I have an Idea for you. What you can do is when you show the currently existed value in you html instead of giving name attribute just give data-name attribute. I.e
Change this
<input class="services text" data-service="21" size="40" value="hair" type="text" name="service0" readonly="">
To This
<input class="services text" data-service="21" size="40" value="hair" type="text" data-value="hair" data-name="service0" readonly="">
Now when user update this values you can bind an event in jQuery like below.
$(document).ready(function(){
$(".services input").on("change paste keyup", function() {
if($(this).val() === $(this).attr("data-value"))
{
$(this).removeAttr("name");
}else{
$(this).attr("name",$(this).attr("data-name"));
}
});
});
By this way you can give name attribute to only those elements whose values are changed. Now each time you can serialize the whole form and it will only get the value of changed elements.
Don't forget to give unique class to already existed elements so you can bind on change event. Hope its clear to you.

How to disable value in select option when it already selected by another select option

So, i have a simple form like this:
<div class="form-group">
<label class="">No Inventaris</label>
<div id="container">
<input type="button" name="noInv" class="form-control" id="add_field" value="Klik untuk membuat text field baru"><br>
<script type="text/javascript">
var count = 0;
$(function(){
$('#add_field').click(function(){
count += 1;
$('#container').append(
'<strong >No Inv Barang Ke ' + count + '</strong><br />'
+ '<select id="field_' + count + '" name="fields[]' + '" class="form-control no_inv"><?php $noInv = $this->modelku->select_inv() ?> <?php foreach($noInv->result() as $inv){ ?> <option value="<?php echo $inv->no_inv ?>"><?php echo $inv->no_inv ?></option><?php } ?></select><br>' );
});
});
</script>
</div>
When i click the button the field will regenerate select option, and the value is from database
select_inv function:
public function select_inv()
{
$this->db->select("no_inv");
$this->db->from('detail_barang');
$this->db->where("kondisi = 'Ada' ");
$query = $this->db->get();
return $query;
}
My Question: How can i disable value in select option when it already selected by another select option?

Try this if this is what you need.
i just created a sample dropdown and in my jquery i trigger the event change using the class of all select option then i will get the value of the select and id. after getting the value i check the val if it is empty or not if not empty then i will use the each function for all the select and get their id attribute so i can compare it with the id of the select and if their id is not the same then i will disabled the option with the same value of the selected dropdown.
and i use focus event for getting the previous value so i can reset whether the user change the value of the selected option.
$( document ).ready(function() {
$('body').on('click','#add_field',function(){
count += 1;
$('#container').append(
'<strong >No Inv Barang Ke ' + count + '</strong><br />'
+ '<select id="field_' + count + '" name="fields[]' + '" class="form-control no_inv select_alternate"> <option value="">select</option><option value="test1">test1</option><option value="test2">test2</option><option value="test3">test3</option></select><br></select><br>' );
});
var count =0;
var previous;
var selectedData = [];
$('body').on('click','.select_alternate',function(){
previous = this.value;
});
$('body').on('change','.select_alternate',function(){
var val = this.value;
var id = $(this).attr('id');
if(val != ''){
$(".select_alternate").each(function(){
var newID = $(this).attr('id');
if(id != newID){
$('#'+newID).children('option[value="' + val + '"]').prop('disabled',true);
$('#'+newID).children('option[value="' + previous + '"]').prop('disabled',false);
selectedData.splice($.inArray(val, selectedData),1);
}else{
selectedData.push(val);
}
});
}else{
$(".select_alternate").each(function(){
var newID = $(this).attr('id');
if(id != newID){
$('#'+newID).children('option[value="' + previous + '"]').prop('disabled',false);
}
});
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="form-group">
<label class="">No Inventaris</label>
<div id="container">
<input type="button" name="noInv" class="form-control" id="add_field" value="Klik untuk membuat text field baru"><br>

Recursive previous and next in arrow key press in custom autocomplete with jquery

I have developed customise autocomplete which works fine in terms of data pulling and displaying in the page. I want to enhance it. I want to implement something like this (multiple dataset of typeahead pluggin) where I want to select or set focus on the next and previous li of my autocomplete when down / up arrow key is pressed. Here is my jquery code which populate the autocomplete.
$("input[data-tg-autocomplete]").keyup(function (e) {
if (e.keyCode == 40 || e.keyCode == 38) {
//alert(e.keyCode);
DownUpKeyPress(e.keyCode);
}
else {
var $input = $(this);
//-----------------------------Allowing user to enter atleast one character for auto search
if ($input.val().length > 0) {
var request = $.ajax({
url: $input.attr("data-tg-autocomplete"),
method: "GET",
data: { term: $input.val() },
dataType: "json"
});
request.done(function (JsonData) {
LoadAutoSuggest(JsonData);
});
request.fail(function (jqXHR, textStatus) {
//alert("Request failed: " + textStatus);
});
}
}
});
//========================populate autocomplete
function LoadAutoSuggest(result) {
var tag = "";
$('.custom-autocomplete').html("");
if (result.Destination != undefined) {
tag = tag + "<li class=''>";
tag = tag + "<a href='#' class='list-group-item active disabled AutoCompleteHeader'>";
tag = tag + "Destination";
tag = tag + "</a>";
tag = tag + "</li>";
for (i = 0; i < result.Destination.length - 1; i++) {
tag = tag + "<li class='list-group-item'>";
tag = tag + "<a class='autocompleteListItem' data-type='Destination' data-id='" + result.Destination[i].DestinationID + "'>";
tag = tag + "<div>";
tag = tag + result.Destination[i].DestinationName;
// tag = tag + "<span class='pull-right badge'>14</span>";
tag = tag + "</div>";
tag = tag + "</a>";
tag = tag + "</li>";
}
}
if (result.Business != undefined) {
tag = tag + "<li class=''>";
tag = tag + "<a href='#' class='list-group-item active disabled AutoCompleteHeader'>";
tag = tag + "Business";
tag = tag + "</a>";
tag = tag + " </li>";
for (i = 0; i < result.Business.length - 1; i++) {
tag = tag + "<li class='list-group-item'>";
tag = tag + "<a class='autocompleteListItem' data-type='Business' data-id='" + result.Business[i].BusinessID + "'>";
tag = tag + "<div>";
tag = tag + result.Business[i].BusinessName;
// tag = tag + "<span class='pull-right badge'>14</span>";
tag = tag + "</div>";
tag = tag + "</a>";
tag = tag + "</li>";
//alert(result.Business[i].BusinessName + " ID = " + result.Business[i].BusinessID)
}
}
$('.custom-autocomplete').html(tag);
$('.autocompleteListItem').click(function () {
var id = $(this).attr("data-id");
var type = $(this).attr("data-type");
var text = $(this).text();
$("#searchtext").val(text);
$('.HiddenSearchInput #id').val(id);
$('.HiddenSearchInput #type').val(type);
$('.custom-autocomplete').html("");
$('.Search-submit').trigger("click");
});
$(':not(".search-wrapper")').click(function () {
if ($('.custom-autocomplete li').length > 0) {
$('.custom-autocomplete').html("");
}
});
$('.custom-autocomplete li.list-group-item').first().addClass("focused");
}
function DownUpKeyPress(keyCode) {
//$this = $(this);
if (keyCode == 40) {
// alert('40');
// $this.next().focus();
if ($('.custom-autocomplete li').length > 0) {
var $focused = $('.custom-autocomplete li.focused');
$('.custom-autocomplete li.focused ~ .list-group-item').first().addClass('focused')
$focused.removeClass('focused')
}
return false;
} else if (keyCode == 38) {
//alert('38');
// $this.prev().focus();
if ($('.custom-autocomplete li').length > 0) {
}
return false;
}
}
and here is my html where I am populating the autocomplete
<div class="Search-container">
<span class="error search-validation"></span>
<div class="input-group input-group-lg">
<input id="searchtext" name="searchtext" type="text" class="form-control " placeholder="Find travel agents, search travel agents in your destination" data-tg-autocomplete="#Url.Action("AutocompleteBusiness")" />
<span class="input-group-btn">
<button class="btn btn-primary Search-submit" type="submit">
<span class="glyphicon glyphicon-search"></span>
</button>
</span>
</div><!-- /input-group -->
<div class="displaynone HiddenSearchInput">
<input type="hidden" id="id" name="id" value="" />
<input type="hidden" id="type" name="type" value="" />
</div>
</div>
<ul class="list-group custom-autocomplete">
#*List will be populated from ajax call in function LoadAutoSuggest*#
</ul>
My function DownUpKeyPress is for setting focus for next and previous li. Focused li item will be used for site search but I am not been able to set focus on the next and previous li when up/down arrow is pressed. I am using MVC5 for developing my project. Probably I am wrong with jquery. May someone help me out to fix the issue. I dont want to use any pluggin for this.

Add this code in DownUpKeyPress
// for up arrow => Previous Li Focus
if (keyCode == 40) {
if ($('.custom-autocomplete li').length > 0) {
var oBox = $('.custom-autocomplete > .list-group-item.focused').next('li');
var curClass = oBox.attr("class");
if (oBox.length == 0) {
$('.custom-autocomplete > .list-group-item.focused').removeClass('focused');
$('.custom-autocomplete > .list-group-item').first().addClass('focused');
}
else if (curClass == "") {
$('.custom-autocomplete > .list-group-item.focused').removeClass('focused').next('li').next('li').addClass('focused');
}
else {
$('.custom-autocomplete > .list-group-item.focused').removeClass('focused').next('li').addClass('focused');
}
}
return false;
}
// for down arrow => Next Li Focus
else if (keyCode == 38) {
if ($('.custom-autocomplete li').length > 0) {
var oBox = $('.custom-autocomplete > .list-group-item.focused').prev('li');
var curClass = oBox.attr("class");
if (oBox.length == 0) {
$('.custom-autocomplete > .list-group-item.focused').removeClass('focused');
$('.custom-autocomplete > .list-group-item').last().addClass('focused');
}
else if (curClass == "") {
$('.custom-autocomplete > .list-group-item.focused').removeClass('focused').prev('li').prev('li').addClass('focused');
}
else {
$('.custom-autocomplete > .list-group-item.focused').removeClass('focused').prev('li').addClass('focused');
}
}
return false;
}

Validate dynamically generated input box with dynamic ID and name

I have a button that adds two input field onclick. Below is the code:
<button type="button" class="btn btn-warning btn-xs" id="additem">
Click here to add Items</button>
<form>
<div id="inputboxes"></div>
<input type="submit">
</form>
and JQuery is
var i = 1,
j = 1,
k = 1,
l = 1;
$("#additem").click(function () {
$("#inputboxes").append("<div class='form-group'><input type='text' id='iname" +
(j++) +
"' name='iname" +
(i++) +
"' class='form-control' placeholder='Enter Item Name' required='required'/></div> " +
"<div class='form-group'><input type='text' id='iprice" +
(k++) +
"' name='iprice" +
(l++) +
"' class='form-control' placeholder='Enter Item Price' required='required'/></div>");
})
How can i validate these dynamically added input boxes for empty and correct values on submitting the form?

You can do something like:
$('.form-group').each(function(){
var input = $(this).children('input');
if(input.val() == '' || input.val() == undefined){
// the errors you will give
}else{
if(input.attr('id').substring(0, 5) == 'iname'){
//function to validate your iname
}else if(input.attr('id').substring(0, 6) == 'iprice'){
//function to validate your iprice
}
}
});
