Question

ajax clock encounters net::ERR_INSUFFICIENT_RESOURCES error

I recently set up an ajax php clock, but I keep encountering numerous net::ERR_INSUFFICIENT_RESOURCES errors in my console. Can anyone shed some light on why this might be happening?

Below is the code responsible for calling out the clock function:

$(document).ready(function(){  
    setInterval(function(){   
        $(".clock").load('<?php echo get_template_directory_uri(); ?>/melbourne.php');;
    });
}(), 1000);

This is what's included in the Melbourne.php file:

<?php  

date_default_timezone_set('Australia/Melbourne');

echo $date = date('H:i:s');

?>

Answer №1

It appears that you have placed the setInterval delay incorrectly. You mistakenly provided it within the $(document).ready() function, which may be discarding it. As a result, the interval is operating without any delay and continuously sending requests one after another.

Please see the correct implementation below:

$(document).ready(function(){
  setInterval(function(){
    $(".clock").load('<?php echo get_template_directory_uri(); ?>/melbourne.php');
  },1000);
});

Additionally, pay attention to the placement of parentheses after a function expression.

Consider learning about Immediately Invoked Function Expressions (IIFE) by visiting this link: IIFE.

function something(){
  // .. some code
}()

Event handlers require a function expression so they can execute it at a later time. Providing an IIFE will cause the event handler to receive the result of the function execution.

Instead of repeatedly making AJAX calls to Melbourne.php every second, which can drain resources and potentially hit request limits depending on the browser used, I recommend utilizing websockets for a more efficient method of communication. Websockets allow for full duplex mode communication with Melbourne.php, establishing a connection only once.
