Save current time to local storage

[pglevy]

Certainly! To save the current time of an HTML5 audio element to local storage using plain JavaScript, follow these steps:

1. Create Your Audio Element: First, declare your audio element and specify the sound file you want to use. For example:

   var audio = new Audio("song.mp3");

2. Track the currentTime Property: Add an event listener to the audio element to track the currentTime property. This property represents the current playback time in seconds. Here's how you can do it:

   audio.addEventListener("timeupdate", function() {
      // Your code to handle the current time goes here
   });

3. Update Local Storage: Within the event listener function, create variables to hold the minutes and seconds of the current time. You can then save this information to local storage:

   audio.addEventListener("timeupdate", function() {
      var currentTimeInSeconds = Math.floor(audio.currentTime);
      // Convert seconds to minutes and seconds
      var minutes = Math.floor(currentTimeInSeconds / 60);
      var seconds = currentTimeInSeconds % 60;
   
      // Save the current time to local storage
      localStorage.setItem("audioCurrentTime", minutes + ":" + seconds);
   });

4. Retrieve the Saved Time: Whenever you need to retrieve the saved current time, simply read it from local storage:

   var savedTime = localStorage.getItem("audioCurrentTime");
   console.log("Saved current time: " + savedTime);

Remember to adjust the event listener and other parts of the code according to your specific use case. This approach ensures that the current time is saved to local storage whenever it changes during audio playback. 🎵🕰️

Try it on an interval to keep it from running too much:

Certainly! To create a timer in JavaScript that listens for an event every 10 seconds, you can use the setInterval() function. Here's how you can achieve this:

1. Using setInterval(): The setInterval() method allows you to execute a function repeatedly at specified time intervals. In your case, you want to listen for an event every 10 seconds. Here's an example:

   // Define your event-handling function
   function handleEvent() {
      // Your code to handle the event goes here
      console.log("Event occurred!");
   }
   
   // Set up the interval (10 seconds = 10000 milliseconds)
   const intervalTime = 10000; // 10 seconds
   const intervalId = setInterval(handleEvent, intervalTime);
   
   // To stop the interval (if needed):
   // clearInterval(intervalId);

   In the above code:

   • Replace handleEvent() with your actual event-handling logic.
   • The intervalTime is set to 10 seconds (10000 milliseconds).
   • The setInterval() function will call handleEvent() every 10 seconds.

2. Stopping the Interval: If you want to stop the interval (for example, when a specific condition is met), use clearInterval(intervalId):

   // To stop the interval (if needed):
   clearInterval(intervalId);

Remember to adjust the event handler function (handleEvent()) to match your specific use case. This approach ensures that your event is triggered every 10 seconds. 🕰️🔔
