javascript - 当计数器达到特定数字时如何触发 JavaScript？

Question

我想在计数器达到特定数字(例如 10)时触发 JavaScript。 我该怎么做？

<button onclick="stepupfunction()"> PRESS ME </button>
<script>
     document.addListener('onLoad', function documentLoaded(e) {
        document.getElementById("score").value = store.get('putAKeyHere') || 0;
    })
    function stepupfunction() {
        document.getElementById("score").stepUp(1);
        store.set('putAKeyHere',document.getElementById("score").value)
    }
</script>

Answer 1

类似以下内容应该有效:

function stepupfunction() {
    var num = document.getElementById("score");
    num.stepUp(1);
    store.set('putAKeyHere', num.value);
    if (num.value >= 10) {
          // DO SOMETHING
    }
}
