Submit whole form when select option is changed without reload page

I need to submit the whole form when I change a select option and save it to mysql without reload page.
I have this code, but only POST the select option value and I need to POST the hidden values in the form too.
<form class="form-horizontal" method="POST" action='#' name="dateForm">
<input type='hidden' name='cond_acao' class='form-control' value="edit_seccao_formando">
<input type="hidden" name="id_formando" value="<?=$linha_formandos[id_formando];?>">
<select name="id_seccoes" class="form-control" onchange="return postSelection">
<option selected="selected" value="1">car</option>
<option value="2">boat</option>
<option value="3">plane</option>
</select>
<div id='response_seccoes'></div>
<script>
function postSelection(selectObject) {
var id_seccoes = window.dateForm.id_seccoes.value = selectObject.options[selectObject.selectedIndex].value;
var dataString = "id_seccoes=" + id_seccoes;
$.ajax({
type: "post",
url: "url.php",
data: dataString,
success: function(response) {
$('#response_seccoes').html("ok").fadeIn(100).delay(2000).fadeOut("slow");
//$("#list").html(response);
}
});
return false;
};
</script>
</form>
It's possible to serialize instead of especified the strings?
Can anyone help me please? Thank you
you are using Jquery, I suggest you monitor the select button for change using a jquery function like
$("id_seccoes").change(function(){
//call your post method here.
});
Replace your code with this.
<form class="form-horizontal" method="POST" action='#' name="dateForm">
<input type='hidden' name='cond_acao' class='form-control' value="edit_seccao_formando">
<input type="hidden" name="id_formando" value="<?=$linha_formandos[id_formando];?>">
<select name="id_seccoes" class="form-control">
<option value="1">car</option>
<option value="2">boat</option>
<option value="3">plane</option>
</select>
</form>
<div id='response_seccoes'></div>
<script>
$(document).ready(function(){
$('[name="id_seccoes"]').change(function(){
$.post('url.php',$('[name="dateForm"]').serialize(),function(response){
$('#response_seccoes').html("ok").fadeIn(100).delay(2000).fadeOut("slow");
});
});
});
</script>

<div class="form-group">
<legend>Options to Search</legend>
<select class="form-control firstdropdown" name="sel_options" id="mystuff">
<option>Select Options</option>
<option value="opt1">Scholership Programs</option>
<option value="opt2">Family Income</option>
</select>
</div>

<option value="opt1">Family Income1</option>
<option value="opt2">Family Income2</option>
</select>
</div>
</div>
This is my script
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/multi-select/0.9.12/js/jquery.multi-select.min.js"></script>
<script>
$( document ).ready(function() {
$('.mystaff_hide').addClass('collapse');
$('#mystuff').change(function(){
var selector = '.mystaff_' + $(this).val();
$(selector).collapse('show');
});
});
</script>
After lot of search i got this code which is shows only recent related selected option's div
<?php if(isset($_POST['sel_options']) &&
!empty(isset($_POST['sel_options']))){
?>
<script>
var selected_option = "<?php echo $_POST['sel_options']; ?>";
var selector = '.mystaff_' + selected_option;
//show only element connected to selected option
$(selector).collapse('show');
</script>
<?php } ?>
Take a look at localStorage or sessionstorage to store information about the state of webpage and read them after reload to restore the UI state
Example:
Localstorage
// Store
localStorage.setItem("lastname", "Smith");
// Retrieve
document.getElementById("result").innerHTML = localStorage.getItem("lastname");
Sessionstorage
if (sessionStorage.clickcount) {
sessionStorage.clickcount = Number(sessionStorage.clickcount) + 1;
} else {
sessionStorage.clickcount = 1;
}
document.getElementById("result").innerHTML = "You have clicked the button " +
sessionStorage.clickcount + " time(s) in this session.";
Or you may want to use AJAX
AJAX is the art of exchanging data with a server, and updating parts of a web page - without reloading the whole page.
As you are using jquery, you may want to look at using Ajax in jquery.
// this is the id of the form
$("#idForm").submit(function(e) {
var url = "path/to/your/script.php"; // the script where you handle the form input.
$.ajax({
type: "POST",
url: url,
data: $("#idForm").serialize(), // serializes the form's elements.
success: function(data)
{
alert(data); // show response from the php script.
}
});
e.preventDefault(); // avoid to execute the actual submit of the form.
});

on change not working in nested dropdown list

hello i want to display data of business3's data according to business2's and business2's data according to business1's dropdown list but on change() of business1 i got data in response but I didn't get second on change() in dropdown list.
<!-- ajax code for first business starts here -->
<script>
$(document).on('change', 'select.Business1', function(){
var business1 = $('select.Business1 option:selected').val();
alert(business1);
var value = $(this).val();
$.ajax({
type:"POST",
data: { business1:business1 },
url: '<?php echo site_url('client_area/select_business_sub_cat'); ?>',
success : function (data){
$('#business2').empty();
$('#business2').append(data);
}
});
});
</script>
<!-- ajax code for first business ends here -->
// This script is not working. i can't find second change event.
<!-- ajax code for second business starts here -->
<script>
$(document).on('change','#business2',function(){
alert('Change Happened');
});
</script>
<!-- ajax code for second business ends here -->
I have tried with live() method also so alert called on first dropdown selection and then the ajax request calls so second drop down fills (Alternate for second script) ,
<script>
$(document).live('change', '#business2', function() {
alert('Change Happened');
});
</script>
Model function
public function select_business_sub_cat()
{
$business1 = $this->input->post('business1');
$result_sub_cat1 = $this->db->query("select category.id,subcategory.* From category LEFT JOIN subcategory ON category.id = subcategory.category_id where category.id = '$business1'");
$row_cat1 = $result_sub_cat1->result();
$data = array(
'id' => $row_cat1['0']->id,
'name' => $row_cat1['0']->name
);
echo "<option value='" . $row_cat1['0']->id . "'>" . $row_cat1['0']->name . "</option>";
// return $this->output->set_output($data);
}
View --
<div class="form-group">
<label>Business 1</label>
<select name="txtBusiness1" id="" style="height: 30px;width: 100%;" class="Business1">
<option value=""> Select Business </option>
<?php
$result_cat1 = $this->db->query("select * from category");
$row_cat1 = $result_cat1->result();
?>
<?php foreach($row_cat1 as $item){ ?>
<option value="<?php echo $item->id; ?>"><?php echo $item->name; ?></option>
<?php } ?>
</select>
</div>
<div class="form-group">
<label>Business 2</label>
<select name="txtBusiness2" id="business2" style="height: 30px;width: 100%;" class="Business2">
<option value=""> Select Business2 </option>
</select>
</div>
<div class="form-group">
<label>Business 3</label>
<select name="txtBusiness4" id="business3" style="height: 30px;width: 100%;" class="Business3">
<option value=""> Select Business3 </option>
<?php echo $abc; ?>
</select>
</div>
Maybe that's because by calling $('#business2').html(data); you remove the event handlers, from jQuery documentation: http://api.jquery.com/html
When .html() is used to set an element's content, any content that was
in that element is completely replaced by the new content.
Additionally, jQuery removes other constructs such as data and event
handlers from child elements before replacing those elements with the
new content.
One option would be to use empty and append like this
$('#business2').empty();
$('#business2').append(data);
instead of $('#business2').html(data);
The Script which is not working for you !!!
<script>
$(document.body).on('change','#business2',function(){
alert('Change Happened');
});
</script>
Try this in place of the above script :
$(document).on("change", "#business2", function(){
alert('Change Happened');
});

POST something using editable dropdown

I made an editable dropdown menu :
<html>
<body>
<div style="position:relative;width:200px;height:25px;border:0;padding:0;margin:0;">
<select style="position:absolute;top:0px;left:0px;width:200px; height:25px;line-height:20px;margin:0;padding:0;" onchange="document.getElementById('displayValue').value=this.options[this.selectedIndex].text; document.getElementById('idValue').value=this.options[this.selectedIndex].value;">
<option></option>
<option value="one">one</option>
<option value="two">two</option>
<option value="three">three</option>
</select>
<input type="text" name="displayValue" placeholder="add/select a value" id="displayValue" style="position:absolute;top:0px;left:0px;width:183px;width:180px\9;#width:180px;height:23px; height:21px\9;#height:18px;border:1px solid #556;" onfocus="this.select()">
<input type="hidden" name="idValue" id="idValue">
</div>
</body>
</html>
I want to POST the value that was added, so as to include it in drop down for the next round.
I suggest you use jQuery for easy implementation. You can wrap them in a form and do the POSTing via jQuery Ajax then store that value somewhere for future use then append it to the next as the new option item.
POST via aJax
$(function() {
$('#form').on('submit', function(e) {
// do not reload the page
e.preventDefault();
// do the posting
var newValue = $('#displayValue').val();
$.post('http://MYURL.com/post.php', {
new_field: newValue
}, function(data) {
// success callback
$('#form > select').append('<option value="'+newValue+'">'+newValue+'</option>');
})
});
})
Basically, you post newValue to http://MYURL.com/post.php and handle that new data then the success callback will handle the inserting of the new value to your select.
the code is not tested, let me know if it did not work

Getting a default value from dropdown and display a table

I am trying to display a HTML table in my index.php page with user registration data which process in table.php page. I am sending a value from a dropdown to the server for processing the data. These everything working for me. But my problem is when my index page load it is not display my table. If I need to display the table I want to select a value from the dropdown.
So anybody tell me how can I make a default value for dropdown (example 05) to display table when page is always loading.
This is my Jquery :
$('#filter-value').change(function(){
var filterValue = $(this).val();
//console.log(filterValue);
$.ajax({
type: 'post',
url: 'table.php',
dataType: 'html',
data: {filter: filterValue},
success:function(data){
$('#response').html(data);
//alert(data);
},
error:function (xhr, ajaxOptions, thrownError){
//On error, we alert user
alert(thrownError);
},
complete: function(){
//alert('update success');
}
});
});
This is HTML
<div id="manage_user">
<form action="" method="">
<div id="response"></div>
<button id="FormSubmit">Add New User</button>
</form>
</div>
<br />
<div style="margin: 0 20px 20px;">
<form method="post" action="">
<select id="filter-value" name="filter">
<option value="5">5</option>
<option value="10">10</option>
<option value="20">20</option>
<option value="30">30</option>
</select>
</form>
</div>
Thank you.
The easiest way to do this without rewriting your code would be to change the value of the drop down and then trigger the change event so that the your existing event handler gets called when the DOM is ready. Something like:
$(document).ready(function() {
$('#filter-value').val(5).change();
});
