What is the best way to modify the properties of an object as soon as a specific condition is satisfied

I'm currently working on enabling a button transition from .disabled = true to .disabled = false. My project involves creating a Yahtzee game clone for entertainment, where players need to select a score to keep after their third roll. Once that choice is made, the button should become unlocked allowing them to roll again. I attempted to achieve this but encountered crashes. My initial idea was to use a while statement to wait until a score is chosen. The variable ptsss keeps track of the number of scores entered.

if(rollcount == 3){
      while (ptsss * 3 < rollcount){
         document.getElementById("rollbutton").disabled = true;
         if (ptsss * 3 == rollcount){
            document.getElementById("rollbutton").disabled = false;
            break;
         }
      }
    }
    }

Answer №1

To improve the code, consider converting the while loop into a function that can enable or disable the roll button based on certain conditions. Here is an example:

function checkRollButton( rollcount, ptsss) {
  if(rollcount == 3) {
    document.getElementById("rollbutton").disabled = ptsss != 1;
  }
}

You can then use or embed the checkRollbutton function in event handlers that update values like rollcount and ptsss.

Note that ptsss should not be altered by other parts of the code while the while loop is running due to JavaScript's single-threaded nature.
I have made adjustments to how the roll button is enabled or disabled in line with the expected behavior, but please review it before implementation.

When it comes to JavaScript, loops function differently compared to other programming languages.

If the loop's condition remains constant within the loop, it will not change unless it occurs inside an asynchronous function.

Avoid using getElement repeatedly within a loop.

To replicate the functionality of a while loop in other languages, JavaScript utilizes an interval.

Therefore, an updated code snippet might resemble the following (without the initial if statement and with modifications to the nested if statement):

var roll=document.getElementById("rollbutton") // ensure this is executed after the element loads

var inter=setInterval(function(){
    if (ptsss * 3 == rollcount) {
        roll.disabled = false;
        clearInterval(inter);
        // Acts like 'break' in a while loop; you can resume the interval later
    }
    if (ptsss * 3 < rollcount){
       roll.disabled = true;
   }
}, 1000/30); // 30 FPS
