the event of onchange at select control at php, trigger issue

I used this select which show counteries
<section class="shipping-calculator-form-shortcode" >
<p class="form-row form-row-wide" id="calc_shipping_country_field">
<label >Shipping options to</label>
<select onchange="myFunctionShipping(this)" name="calc_shipping_country" id="calc_shipping_country" class="ss-woo-shipping-calculator" rel="ss-woo-shipping-calculator">
<option value="1"><?php _e( 'Select a country…', 'woocommerce' ); ?></option>
<?php
foreach ( WC()->countries->get_shipping_countries() as $key => $value )
echo '<option value="' . esc_attr( $key ) . '"' . selected( WC()->customer->get_shipping_country(), esc_attr( $key ), false ) . '>' . esc_html( $value ) . '</option>';
?>
</select>
</p>
<span id="ss-woo-shipping-calculator-loading" style="display:none"><img src='<?php echo plugins_url( '/default.gif', __FILE__ ) ?>' /></span>
</p>
<?php wp_nonce_field( 'woocommerce-cart' ); ?>
<div id="ss-woo-shipping-result">
</div>
</section>
then by javascript code to retrieve the shipping options for it
<script type="text/javascript">
var $s = jQuery.noConflict();
function myFunctionShipping(item) {
$s(document).ready(function($) {
$("select").change(function(){
var ajaxurl = "<?php echo admin_url('admin-ajax.php'); ?>";
var country = item.value;
$("#ss-woo-shipping-calculator-loading").show();
var data = {'action': 'ss_woo_shipping_calculator','country': country};
$.post("<?php echo get_home_url(); ?>", data, function(response) {
$("#ss-woo-shipping-calculator-loading").hide();
response = JSON.parse(response);
if(response.result == 1){
$("#ss-woo-shipping-result").html(response.message);
}else{
$("#ss-woo-shipping-result").html("");
}
return false;
});
return false;});
});
}
the problem that:- it trigger if also any other select control changed
also it is only trigger after changing the selection twice (after page loading)

It "says" that action apply to any select $("select").change(). You can change to limit action only to select with chosen id like
$("#calc_shipping_country").change(function()
or you can choose to use select class name.
EDIT.
My mistake, I didnt figure out that the action is called by function and not select action. Try to remove completely the $("select").change(function() wrap and make look something like this
<script type="text/javascript">
var $s = jQuery.noConflict();
function myFunctionShipping(item) {
$s(document).ready(function($) {
var ajaxurl = "<?php echo admin_url('admin-ajax.php'); ?>";
var country = item.value;
$("#ss-woo-shipping-calculator-loading").show();
var data = {'action': 'ss_woo_shipping_calculator','country': country};
$.post("<?php echo get_home_url(); ?>", data, function(response) {
$("#ss-woo-shipping-calculator-loading").hide();
response = JSON.parse(response);
if(response.result == 1){
$("#ss-woo-shipping-result").html(response.message);
}else{
$("#ss-woo-shipping-result").html("");
}
return false;
});
return false;
});
}
</script>

Autofilling Textboxes with Javascript and PHP

I check if the user is logged in with, if they are then i pull their details from the database, i then want to auto fill this data into part of my form.
while(OCIFetch($stmt)) {
if(OCIResult($stmt,"PASSWORD")==$Password) {
$flag=true;
$First=OCIResult($stmt,"FIRSTNAME");
$Sur=OCIResult($stmt,"SURNAME");
$Email=OCIResult($stmt,"EMAIL");
$Phone=OCIResult($stmt,"PHONE");
$Address=OCIResult($stmt,"ADDRESS");
$City=OCIResult($stmt, "CITY");
$Post=OCIResult($stmt, "POSTCODE");
//set up session - Declare session variables and assign their corresponding values
session_start();
$_SESSION['RegUser'] = OCIResult($stmt,"USERNAME");
$_SESSION['RegFirst'] = $First;
$_SESSION['RegSur'] = $Sur;
$_SESSION['RegEmail'] = $Email;
$_SESSION['RegPhone'] = $Phone;
$_SESSION['RegAdd'] = $Address;
$_SESSION['RegCity'] = $City;
$_SESSION['RegPost'] = $Post;
}
This is the code im currently attempting to use to auto fill but the fields still appear blank
//Autofill the details if the user is logged in
window.onload = function() {
document.forms['Order']['RegFirst'].value = "<?php echo $First?>";
document.forms['Order']['RegSur'].value = "<?php echo $Sur?>";
document.forms['Order']['RegEmail'].value = "<?php echo $Email?>";
document.forms['Order']['RegPhone'].value = "<?php echo $Phone?>";
document.forms['Order']['RegAdd'].value = "<?php echo $Address?>";
document.forms['Order']['RegCity'].value = "<?php echo $City?>";
document.forms['Order']['RegPost'].value = "<?php echo $Post?>";
}

You don't need javascript for this, just echo the values into your html form fields
<input id="example" value="<?php echo $Post?>" />
Rinse and repeat for all other form fields.

Try this,
//Autofill the details if the user is logged in
window.onload = function() {
document.forms['Order']['RegFirst'].value = "<?php echo $_SESSION['RegFirst'];?>";
document.forms['Order']['RegSur'].value = "<?php echo $_SESSION['RegSur'];?>";
document.forms['Order']['RegEmail'].value = "<?php echo $_SESSION['RegPhone'];?>";
document.forms['Order']['RegPhone'].value = "<?php echo $_SESSION['RegPhone'];?>";
document.forms['Order']['RegAdd'].value = "<?php echo $_SESSION['RegAdd'];?>";
document.forms['Order']['RegCity'].value = "<?php echo$_SESSION['RegCity'];?>";
document.forms['Order']['RegPost'].value = "<?php echo $_SESSION['RegPost'];?>";
}

echoing javascript with php including mysql row variables

I'm trying to echo javascript code using php and trying to retrieve data from my database within this very echo-code... Does anybody know what I'm doing wrong? Is it because javascript is only client-side? (Technically, I'm trying to reach the database with php...) I would appreciate some help!
<?php
if($condition == true){
//connect to the database
//-select the database to use
//-query the database table
//-run the query against the mysql query function
//-create while loop and loop through result set
echo "<script>
items_set = [
{
src : '<?php echo ".$row['imageURL']." ?>',
url : '<?php echo ".$row['URL']." ?>',
category: '<?php echo ".$row['DetailCategory']." ?>',
title : '<?php echo ".$row['Name']." ?>',
description : '<?php echo ".$row['Description']." ?>',
price : '<?php echo ".$row['Price']." ?>',
location : '<?php echo ".$row['Postcode']." ?>',
thirdparty : '<?php echo ".$row['ThirdParty']." ?>',
thirdparty_mobile : '<?php echo ".$row['Thirdparty']." ?>'
}
];
jQuery('#list').portfolio_addon({
load_count : 1,
items : items_set
});
</script>";
}}
?>
Thanks in advance!
(In Dreamweaver the colors of the code look right, unlike here)

Make sure you separate what gets executed in your server (PHP) and what is passed to the client and executed in the browser:
<?php if(condition == true){ ?>
<script>
items_set = [
{src : "<?php echo $row['imageURL']; ?>",
url : "<?php echo $row['URL']; ?>",
category: "<?php echo $row['DetailCategory']; ?>",
title : "<?php echo $row['Name']; ?>",
description : "<?php echo $row['Description']; ?>",
price : "<?php echo $row['Price']; ?>",
location : "<?php echo $row['Postcode']; ?>",
thirdparty : "<?php echo $row['ThirdParty']; ?>",
thirdparty_mobile : "<?php echo $row['Thirdparty']; ?>"}
];
jQuery('#list').portfolio_addon({
load_count : 1,
items : items_set
});
</script>
<?php } ?>
Notice I modified your code to make strings variables, given that the $row variable is part of your PHP code, not your JavaScript.

in your php:
//specify header..
header("content-type:application/json");
//create variables for your values
$row['values'];
//create oo array
arrayResult =
array(
array("variable-name" => $variable,"imageURL" => $imageURL)
);
In your html..
//get data using JSON
<script type="text/javascript">
$j.getJSON( "cellJson.php", function( json ) {
$j.each(json, function(i, item) {
//example
var imageURL = item.imageURL;
//then in your script
items_set = [
{
src : ''+imageURL+'',
url : ''+URL+'',
category: ''+DetailCategory+'',
title : ''+Name+''
}
];
jQuery('#list').portfolio_addon({
load_count : 1,
items : items_set
});
});
</script>

php to js variable not setting at run time

issue : i am able to set and get run time variable value ?
steps: onlick button random number,
expected output :alert pop in broswer and number should be shows inside alert .
<html>
<head>
<title>Pass variable from PHP to JavaScript - Cyberster's Blog'</title>
</head>
<body>
<input type="button" value="random number " onclick="location='php2js2.php'" />
<script>
// var js_var = "<?php echo $php_var; echo $randomString ?>";
//alert(js_var);
var js_var_key = "<?php echo $RandomString(6); ?>";
alert(js_var_key);
</script>
</body>
</html>
<?php
function RandomString($length) {
$keys = array_merge(range(0,9), range('a', 'z'));
for($i=0; $i < $length; $i++) {
$key .= $keys[array_rand($keys)];
}
return $key;
}
#$php_var = "Hello world from PHP";
#$length = 10;
#$randomString = substr(str_shuffle("0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"), 0, $length);
?>
==

You should not keep $ infront of RandomString..Please remove that and check and add this .. you will find the alert with a random number
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
$(document ).ready(function() {
var js_var_key = "<?php echo RandomString(6); ?>";
alert(js_var_key);
});
</script>

var js_var_key = "<?php echo $RandomString(6); ?>";
change this line to (remove $)
var js_var_key = "<?php echo RandomString(6); ?>";
and add
$key="" before
for($i=0; $i < $length; $i++) {
