It looks like you've got pretty much what you need already however you are directly placing you're update into the div with jQuery instead of saving it.

Change

Code:

var updateInterval = setInterval(function() {
 $('#thealert').load('alertprice.php');
},1*1000);

To something like

Code:

var alertPriceVariable;
var updateInterval = setInterval(function() {
$.get( "alertprice.php")
  .done(function( data ) {
    alertPriceVariable = data;
   $('#thealert').text(alertPriceVariable);
  });
},1*1000);

Not sure if this will help but this is how I get a changing php value into javascript.

Code:


	
		
453.33


	
// alertprice.php

	$result= mysqli_query($conn, "SELECT price FROM latestprice");
		while($row = mysqli_fetch_array($result)){ 
			$latest_price = $row['price'];
		}

echo $latest_price;



?>

And to get the div back into javascript

Code:

latestPrice = document.getElementById("thealert").innerHTML;

or

latestPrice = xhttp.responseText;

Not quite sure I follow...

If you have the number in php, you can send it to javascript like this:

Code:

But, this would only run when the page first loads... if you are updating via $.ajax() or curl(), I would send a callback function to update the variable with the response data

If you are trying to update a div using jquery, I use something like:

Code:

$('#latestPrice').change(function() {
  $("#latestPriceDisplay").html($(this).val());
});

Problem is that my div or variable is updating when price changes and when you do this

var latestPrice = ;

you will not get updated price until page refresh.I want the variable to update with price change without refresh

In my js file i have this:

var updateInterval = setInterval(function() {
$('#thealert').load('alertprice.php');
},1*1000);

In my php file i SELECT the latest price from MYSQL database for example 453.33

In html it shows at time 14:00:01 :

453.33

Then at time 14:00:02 :

463.33

How do i get the updated value in a jquery or php variable so i can use it for an alert script ?

I want always to have in variable:

$latestprice = "463.33";

Or what ever latest price is at current time.

I want to store the updated value inside the div in a php variable or jquery or javascript variable to be used by other scripts ,if div value changes then $latestprice should change also.

Update:$latestprice needs to go in here:
