How to accumulate random numbers with each button click in JavaScript

I need help with a JavaScript function that creates random numbers between 1 and 10 when I click a button. The tricky part is that each new click should add the new random number to the previous total, making it grow bigger each time.

Here’s what I have so far, but I can’t figure out how to keep adding the numbers together:

$(document).ready(function () {
  $('#spinner-button').click(function () {
    var minValue = 1;
    var maxValue = 10;
    var randomResult = Math.floor(Math.random() * (maxValue - minValue + 1)) + minValue;

    $('#spinner-element').css({
      'transform': 'rotate(' + randomResult * 72 + 'deg)'
    });

    console.log('Random result: ' + randomResult);
  });
});

I want the numbers to keep adding up so if I get 3 on the first click and 7 on the second click, the total should be 10. How can I modify this code to store and add the values?

Your code generates a fresh random number each click but doesn’t keep track of anything. You need a variable that sticks around between clicks. Move your sum variable outside the jQuery ready function - or at least outside the click handler. Try var runningTotal = 0; right after your document ready line. Then in your click function, do runningTotal += randomResult; and log it with console.log('Running total: ' + runningTotal);. I’ve done this tons of times for game scores. It’s all about variable scope - stuff declared inside the click function resets every time, but outer scope variables stick around between clicks.

This is a common issue when managing state in JavaScript. To keep a running total that persists across button clicks, you need to declare a variable outside the click handler. Start by placing var accumulatedTotal = 0; right after your document ready function. Then, within your click handler, simply add to this variable using accumulatedTotal += randomResult; after generating each random number. If you want to display the current total on the page, you could update an element like $('#total-display').text('Total: ' + accumulatedTotal);. Maintaining this variable in the outer scope prevents it from resetting with each click, which is crucial for accumulating values.

just declare a variable outside ur click func to track the total. put var totalSum = 0; before the click event, then add totalSum += randomResult; inside after u get the random number. display it whenever u want.
