I’m creating a Javascript game and I’m currently trying to write some code that will show the player’s “Gold Balance” in real time on a html webpage.
The Gold amount is contained in my SQL database, so I’m using setInterval with a Javascript function that contains an AJAX call which calls a PHP script that grabs the current balance amount for the player and sends it back as “response”.
I’m able to have this amount appear as a Javascript alert, however I need to have the response appear as text on the webpage inside a <div> instead.
This is my current code:
<script>
setInterval("checkGold()",5000);
function checkGold()
{
$.ajax({
url: 'scripts/checkGold.php',
data: "",
dataType: 'json',
success: function(response){
alert(response);
}});
};
</script>
I have this in my html source code, I would like to place the function in a separate file and call it from there, but when I tried this I wasn't able to send the response back to the html page correctly.
I was wondering if anyone knows how to have this response appear as text on the page inside <div> </div>?
Also, I was wondering if this method will really update the div in real time (ie, will it auto-refresh the div part of the webpage, showing an up to date value (every 5000 milliseconds)?
Thanks in advance!
Since you are using jQuery, you can use text() to alter the contents of an existing div (which id is "yourDiv"):
setInterval("checkGold()",5000);
function checkGold()
{
$.ajax({
url: 'scripts/checkGold.php',
data: "",
dataType: 'json',
success: function(response){
$('div#yourDiv').text(response);
}
});
};
You have two questions here, so I will try to address both
1) How to append to the DOM using jQuery, instead of an alert:
in the success callback function, instead of alerting the response, you can simply call
$('body').append("<div>"+response+"</div>")
2) "Real time" Gold Balance
