How to get a post ID php using js

here I want to display the data id based on the click button using js
my code:
var idPost = document.getElementsByClassName("getID")[0];
idPost.onclick = function() {
var GetID = window.location.protocol + "//"
+ window.location.host
+ window.location.pathname
+ '?id=<?php echo $id;?>';
window.history.pushState({ path: GetID }, '', GetID );
}
why my code isn't working?
maybe someone here can help my problem

This may will help you:
EDIT
location.href reloads page to indicated url
var idPost = document.getElementsByClassName("getID")[0];
idPost.onclick = function() {
let id = "<?php echo $id; ?>";
location.href = `?id=${id}`;
}

Autocomplete a field from URL

My URL is something like this: www.website.com/referral456
In the checkout page of my ecommerce I have a referral field that users have to manually complete with the referral number (in that case 456).
How this field could autocomplete itself directly from the URL?

Just get the current url or param passed (if your app has a router etc).
Then just strip all but the numbers from the string:
<?php
$_SERVER['REQUEST_URI'] = '/referral456';
$value = basename($_SERVER['REQUEST_URI']);
echo preg_replace('/[^0-9]/', '', $value); //456
Then populate the field with it.

window.onload = function(){
var param = this.href.substr(this.href.lastIndexOf('/') + 1);
document.getElementById('input#userInputField').value=param;
}

Try this
window.onload = function(){
var getRefId = location.href.split('/')[1].replace('referral','');
document.getElementById('input#refId').value = getRefId ;
}

You could get the url using location.href divide it using split(), and selecting the second element (1) that is referral454654654, then, using replace() you replace referral part with nothing. At the end you have only the number in refId. Here the example:
window.onload = function(){
var refId = location.href.split('/')[1].replace('referral','');
document.getElementById('input#refId').value = refId;
}

How get values variable javascript from razor?

i have soure code :
$("#yes-modal").click(function (e) {
var img = $("#url").val();
window.location = '#Url.Action("DownloadImages", "Hrd", new { id = *value variable img* })';
});
i want get value img, but i have error.
How can do it ? thank you.

Below syntax should work.
window.location = '#Url.Action("DownloadImages", "Hrd", new { id = ' + img + '})';
Let me know if you face any issue.

The razor syntax is a serverside code. It is evaluated while rendering the page from server. But the javascript is evaluated at the client side (browser). So you have to split it like below code.
$("#yes-modal").click(function (e) {
var img = $("#url").val();
var loc = '#Url.Action("DownloadImages", "Hrd")';
var loc += '?id=' + img;
window.location = loc;
});

concat two strings in JQuery

Just like the title above: how to concatenate two strings in JQuery?
This is my code so far:
$(document).ready(function(){
serviceName = '<?=$_GET['services'] . ".php";?>';
serviceID='<?= "#" .$_GET['services'];?>';
serviceClass = '<?=$_GET['services'];?>';
if (serviceName != "") {
alert(serviceID);
$('.main_content').load(serviceName);
$(serviceID).addClass("it");
}
});
As you can see in my above code, in variable name serviceID, I am concatenating hashtag and my GET value and I try to put it on ALERT and the result is correct, but when I assign it to .addClass it’s not working.
Any alternatives and solution is much appreciated.

I guess you meant that the PHP code should be evaluated before arriving to the client, therefore your code syntax is correct, but check out the following looks cleaner and also not polluting the global JavaScript scope (that's what the var ... is for):
var serviceClass = '<?="{$_GET["services"]}";?>';
var serviceName = serviceClass+'.php';
var serviceId = '#'+serviceClass;
but, since your code syntax is correct, you should verify that you actually have an element with serviceId as the id when your are executing it
if (($(serviceId)||[]).length) {
alert('your element with the id:'+serviceClass+' exists');
}
else {
alert('your element with the id:'+serviceClass+' doesn\'t exists');
}

i hope this one solve the issue:
<script>
$(document).ready(function(){
serviceName = '<? echo "./".$_GET["services"].".php";?>';
serviceID = '<? echo "#" .$_GET["services"]; ?>';
serviceClass ='<? echo $_GET["services"]; ?>';
console.log(serviceID);
if(serviceName!=""){
alert(serviceID);
$('.main_content').load(serviceName);
$(serviceID).addClass("it");
}
});
</script>
also check the console in your browser (firebug or chrome developer tools) to see the output ,fit your criteria

Try as but not sure, My change is append "#" Id in jquery
<script>
$(document).ready(function(){
serviceName = '<?=$_GET['services'] . ".php";?>';
serviceID='<?= $_GET['services'];?>';
serviceClass = '<?=$_GET['services'];?>';
if(serviceName!=""){
alert(serviceID);
$('.main_content').load(serviceName);
$("#"+serviceID).addClass("it");
}
});
</script>

How to send variable from javascript to PHP on azure websites?

To simplify the problem, all I want is passing 3 variable from javascript to PHP. So let say I have 4 varible : a,b,c,message.
I have tried the following ways:
1)The code below is in my javascript file
window.location.href="somewebsite.php?x=" + a + "&y=" + b + "&z=" + c + "&msg=" + message;
I saw that it actually passing the values to URL, it jump to the PHP website that specifies in the code above but somehow nothing is getting from $_POST['x'] ( I even try $_GET['x'] and $_REQUEST('x') but none of them works at all)
2) Then I tried with ajax
$.post("somewebsite.php",{x:a, y:b, z:c, msg:message})
And same as above nothing are passed to the PHP website.
3) I tried with form submit
I put everything into a form and submit it to the PHP website but what I get from $_POST is an empty array.
So I conclude that something is wrong with azurewebsites server. This is the first time I used window azure so I don't know how it even works. Any suggestion would be appreciated.

you can try out ajax function
$.ajax({
url:"url",
method:"post",
data:{x:a, y:b, z:c, msg:message},
success:function(data)
{
// success code
},
error:function(error)
{
// error code ;
}
});

Should work:
Your js file:
$(document).ready(function(){
var aval = "testas";
var bval = "testas2";
var cval = "testas3";
var msg = "testas4";
$.post('test.php',{a:aval,b:bval,c:cval,message:msg},function(resp){
alert(resp);
});
});
php file should look like:
<?php
$resp = "";
foreach($_POST as $key => $val){
$resp .= $key.":".$val." \n";
}
echo $resp;
?>
After post alert should give response of all sent post values.
I hope it helped you. If yes, don't forget resp. Thanks.

Try sending an array to your somewebsite.php write this inside a function on jquery code.
It must work if you place it on a good place on your code.
var x=new Array();
x[0]='field0';
x[1]='field1';
x[2]='fieldN';
$.post('somewebsite.php',x,function(x){
alert(x);
});
Your somewebsite.php could be like this.
<?php
if(!isset($_POST['x']))$x=array();else $x=#$_POST['x'];
for($i=0;$i<count($x);$i++)
echo "X ($i) = ".$x[$i];
?>
Happy codings!
