Multiple Delete/Update using php- Codeigniter Ajax

The console.log(response) returns the code of whole page in console when I inspect it in ajax . I have created a codeigniter project with MySQL as back end database . I have fetched content from table from database into table. Now I want to give option to user of mulitple delete. Please take it into account that I am not actually deleting value from table I am just turning status of of that row to inactive. It goes as :
If status= 0 : the row's data will be visible in table.
If status= 1:the row's data will not be visible in table.
I have given checkbox option in the table to select multiple checkbox.
Here is my javascript:
To check all the check boxes:-
<script language="JavaScript">
function selectAll(source) {
checkboxes = document.getElementsByName('sport');
for(var i in checkboxes)
checkboxes[i].checked = source.checked;
}
</script>
javascript to get value's from the checkboxes and send it to controller:
<script type="text/javascript">
function okay(){
var favorite = [];
$.each($("input[name='sport']:checked"), function(){
favorite.push($(this).val());
var txt=$(this).val();
});
for (var i = 0;i<favorite.length;i++) {
$.ajax({
url:('<?=base_url()?>/Repots/supervisor_muldel'),
type:'POST',
data:{'value_id':favorite[i]},
success:function(response)
{
console.log(response);
},
error:function(response)
{
console.log('nahi gaya');
},
});
//console.log(favorite[i]);
}
//alert("My favourite sports are: " + favorite.join(", "));
}
</script>
every check box is associate with particular values.
here the html button to call the fucntion:
<button onclick="okay();">Delete Selected</button>
Controller:Reports/supervisor_muldel:
//multiple delete supervisor
public function supervisor_muldel() {
$value_id = $this->input->post('value_id');
$selected_supervisor = array('supervisor_id' =>$value_id);
$staus=array('status'=>1);
$this->load->model('Entry_model');
$result = $this->Entry_model->supervisor_muldel($staus,$selected_supervisor);
}
Entry_model/supervisor_muldel:
//delete multiple supervisor
public function supervisor_muldel($staus,$condition)
{
$this->db->trans_start();
$this->db->where($condition)
->update('tbl_supervisor',$staus);
$this->db->trans_complete();
}
The console.log returns the code of whole page in console.I am stuck here.

You have put wrong ajax request URL.
Change
url:('<?=base_url()?>/Repots/supervisor_muldel'),
to
url:('<?=base_url()?>/Reports/supervisor_muldel'),
Look at the controller name in URL.

Iterating through rows in DataTables using JavaScript

Essentially the problem is that I am getting duplicate results in my DataTable.
In my application, the user will enter a value and that value will return an array of objects from the database and those records will then populate in the DataTable. Currently the issue that I am having is that all the records that are in the table are all the same.
There should be 100 different records in the DataTable, instead there is 100 of the exact same record. I am not seeing any examples that show how to iterate though an array of objects from a database, in a way that in can be handled by the DataTable.
I should be able to use rows.add() but that does not have anything displaying in the table and the other option I saw was rows().every() which does not have an example similar to what I am doing.
Any references, resources or insight will be very helpful. Thanks!
User Input:
<p> Year: <input id="YearNbrId" type="text" th:field="*{YearNbr}" /> </p>
Button:
<input type="button" value="Locate" id="goToDetails" />
JavaScript Snippet:
$(document).ready(function() {
var table = $('#Orders').DataTable();
$('#goToDetails').on('click', function() {
var YearNbr = $('#YearNbrId').val();
var url = './eData/locate?YearNbr=' + YearNbr;
$.get(url, function(result) {
console.log(result);
for (var i = 0; i < result.length; i++) {
var myOrder = result[i];
table.row.add([
null, // place holder
myOrder.yearNbr,
myOrder.orderNm,
'<input>', // user input
myOrder.model,
new Date(myOrder.Date).toJSON().slice(0, 10),
myOrder.srcCode,
null,
'<input>'
]).draw(false)
.nodes()
.to$();
}
});
});
});

You might want to check out the JQuery .each function. You probably need to do something like: $(result).each(function(i,obj) {//code here}); Where i is the position in the array and obj is the current record in result.

How to submit dynamically created hidden variables using Jquery

I have created a dynamic table. DEMO to my project.
I have placed this dynamic table in the form under a div named 'box'
<div id="box">
</div>.
I am creating dynamic hidden variables table using Jquery which I need to store in DB. This is how I am creating the hash to submit to server.
criteria = $('form_name').serialize(true);
criteria = Object.toJSON(criteria);
// Build the object to store the parameters for the AJAX post request
parameters = {
title : $('report_title').value,
description : $('report_description').value,
criteria : criteria
}
// Make the AJAX post request
new Ajax.Request( URL, {
method: 'post',
parameters: parameters,
onSuccess: function( response ) {
$('messageSpan').innerHTML = response.responseText;
$('spinner').style.display='none';
}
});
I am not able to capture the dynamically created values in the criteria.
How to solve this?
In the dynamically created section, I tried adding a submit button and see if the values can be fetched. I am able to fetch and iterate all the hidden variables.
$('#jquerysaveButton').click(function(){
jsonObj = [];
$("input[id=rubric_cell]").each(function () {
var id = "cell_" + row + "_" + col;
item = {}
item["id"] = id;
item["selected_rubric"] = $(this).val();
jsonObj.push(item);
});
console.log(jsonObj); //I am getting the required values here
});
How to get these values in the criteria = $('form_name').serialize(true);. Am I doing some thing wrong? Please help me. thanks in advance.
DEMO to my project

You need to make sure that your hidden input fields have a name attribute set otherwise $.serialize will not process them.

Populate items into SELECT with Jquery

I'm having trouble populating a SELECT with jquery, when the user writes the zipcode or part of it, it searches the database and returns this:
{"success":1,"id":"50","street":"Central One"},{"success":1,"id":"60","street":"Central Two"}
One success for each street it finds. For a single street and using a text input I'm using this
UPDATE 1 - FULL CODE
$(document).ready( function() {
$('#zip').blur(function(){
$.ajax({
url : '../../controller/zip.php',
type : 'POST',
data: 'zip=' + $('#zip').val(),
dataType: 'json',
success: function(data){
if(data.sucesso == 1){
$('#id').val(data.id);
$('#street').val(data.street);
}
}
});
return false;
})
});
How can I change this so I can populate a select box.
Thanks

What is being passed back for a single address is a single object from which you can grab the information. When there are multiple responses you need to go through each of them and handle them.
When we look at MDN's article it shows that we need a parent <select> tag and then we need to populate the children. The process would look like this:
Find / create parent select
[Optional] Remove previous child <option> tags
Loop through responses
Create a new <option> element
Populate the <option> with the appropriate value and content
Append it to the parent <select>
Some things to be aware of, if you're clearing the previous addresses each time you get a response from the database you'll want to remove these previous <option>s. This can be done either by .empty() if there are no other children in the parent or starting with the parent <select> and removing all child <options>.

Use this for adding items to select box dynamically:
var $selectBox = $('#selectboxId');
$selectBox.empty();
$.each(data, function (idx, val) {
if (val.success) {
$selectBox.append($('<option>', {
value: val.id,
text: val.street
}));
}
});

I would not encourage to do so; you're better off using a html-templating engine like mustache or handlebars.
Doing this kind of stuff in plain JS (string concatenation) is gross. It pollutes your sourcecode.
Anyways, this would do the trick to generate the necessary HTML:
function generateHTML(data){
return data.reduce(function(o,n){
return o+"<option value='"+n.id+"'>"+n.street+"</option>";
},"");
}
Here is the Fiddle to play with. If you need to filter for success, you could add a filter()
function generateHTML(data){
return data.filter(function(x){
return !!x.success;
}).reduce(function(o,n){
return o+"<option value='"+n.id+"'>"+n.street+"</option>";
},"");
}
You could easily use $("#selectBoxId").html(generateHTML(data)) to insert it to the DOM.
To fit it into your codebase, you should add it in the success handler:
success: function(data){
function generateHTML(data){
return data.reduce(function(o,n){
return o+"<option value='"+n.id+"'>"+n.street+"</option>";
},"");
}
$("select").html(generateHTML(data))
}
For the inner workings of Array.prototype.reduce() take a look at MDN and for Array.prototype.filter()

If the JSON being returned is a list [{...}, ..., {...}], then you can use Array.forEach. Here is the success callback:
function(data) {
data.forEach(function(item) {
if (item.success) {
// use item.id and item.street
}
});
}
If you have a <select> element, then you will want to be populating it with <options>, by appending an <option> element under each successful "if" branch in the forEach.

Assuming you already have the select element on the page and the data that is coming back from the server is an array of objects, this should work:
$.ajax({
url : '../../controller/zip.php',
type : 'POST',
data: 'zip=' + $('#zip').val(),
dataType: 'json',
success: function(data) {
var $items = [];
$.each(data, function(street) {
if(data.success === 1) {
$items.push($('<option />').attr({
value: street.id
}).text(street.street));
}
});
$('#your-select-element').append($items);
}
});
Notice this isn't setting the value for one option, it is creating <option> tags for each of the response's streets and appending them to a <select> element.

difficulty getting list of values from series of input elements inside table rows

I'm completely stumped. Granted, in java script i'm like that kid trying to jam a square peg into a round hole.
My high level objective: The admins want the ability to edit text surrounding some text boxes, as well as the ability to add and remove 'paragraph'. The reporters and users want the values that are in the textboxes to be used in comparisons, etc (which is the original functionality).
My Solution: This project uses a pretty messy value - attribute table (called an EAV?), which now has fields with associated fields and is self referencing. I decided to leverage this to minimize changes to the database, so the admin essentially creates a string, denotes the places a text box belongs using '{}', and assigns a name to the attribute into text boxes that appear directly below the paragraph.
My Problem: Textboxes generate fine, as soon as the admin stops typing the "{}" count is checked client side, and the correct number of textboxes are added/removed in rows below. However, when the "change" mode (and thereby save the new string) I also want to save the attribute names they selected. I can't seem to get the actual value out of the input. The java script below sends null to elementList. Closer inspection indicates that var fieldNames is getting two elements of "undefined" so it makes sense that I'm getting null. Its also apparent that Its hitting something, becuase the number aligns with there being two 'nameField' rows.
DOM (Hemed down to the essentials)
<tr data-editMode="TextMode" data-ordinal="0">
....
<td>
<a class="changeMode">
<tr class="nameField">
<td colspan='4'>
<input type="text" value="Testing">
<tr class="nameField">
....
Javascript
function getAssociatedTr(row) {
var associatedRows = [];
associatedRows.push(row);
row = row.next('tr');
var hasAnother = true;
while (hasAnother == true) {
if (row != null && row.hasClass("nameField")) {
associatedRows.push(row);
row = row.next('tr');
} else {
hasAnother = false;
}
}
return associatedRows;
}
$(".changeMode").live("click", function () {
var options = $(this).data("options");
var theRow = $(this).closest('tr');
var rows = getAssociatedTr(theRow);
var fieldNames = new Array();
rows.splice(0, 1);
for (var index = 0; index < rows.length; index++) {
{
fieldNames.push(rows[index].next('.nameField').val());
}
}
$(".modal-header", c.rowsModal).html("<h3>Changing edit mode" + options.table + "</h3>");
c.rowsModal.modal("show");
$.ajax({
type: "POST",
traditional: true,
data: { "Name": options.table, "Ordinal": options.row, "EditMode": options.editMode, "ElementNames": fieldNames },
url: "/contracts/changeeditmode/" + c.id.val(),
success: function (data) {
theRow.replaceWith(data);
$.validator.unobtrusive.parse("#supplementForm");
c.rowsModal.modal("hide");
for (j = rows.length - 1 ; j >= 0; j--) {
rows[j].remove();
}
}
});
});
Server side
public ActionResult ChangeEditMode(long id, AddTrackedRowViewModel model,
string editMode, List<string> elementNames)
{
}
As a side note, I'm open to constructive criticism on the JavaScript.
EDIT
I have updated the line to
fieldNames.push(rows[index].nextAll('input').first().val());
But still getting undefined.
SOLUTION
fieldNames.push(rows[index].find("input[type=text]").val());

In this line:
fieldNames.push(rows[index].next('.nameField').val());
you are using the selector ".nameField", but this get a "tr" element, if you want the textbox you need this:
fieldNames.push(rows[index].next('.valid').val());
or using other selector that give you the textbox.
