Question

我输入了值，它运行ONCE，这是一个问题。我尝试更改数字，然后再次单击Enter，它什么都不做。它再次工作的唯一方法是，如果我使用滚动来向上或向下移动当前值。

var fuel = 2.5;
  var mpg = 6;

  function Hourly() {
    var miles = document.getElementById('miles').value;
    var brokerPay = document.getElementById('pay').value;
    var gallons = miles / 6;
    var hours = miles / 55;
    var cost = gallons * fuel;
    var net = brokerPay - cost
    var hourlyPay = net / hours;
    var newHeader = document.getElementById('changeMe');
    newHeader.innerHTML = hourlyPay;
  }

<h1 id="changeMe">Change me Here</h1>
<input type="number" placeholder="miles" id="miles" required/>
<input type="number" placeholder="Broker Pay" id="pay" required/>
<input type="submit" value="Enter" onclick="Hourly()" />

onClick只能工作一次
