Question

我正在设置一台新服务器，并希望在不刷新整个页面的情况下自动扣除剩余余额。现在的问题是我必须刷新整个页面才能更新余额。

我已经搜索了有关jQuery的信息，但是我不知道如何使用它。

这是我的代码：

function updateRemaining(field_name, deduction) {
philhealth_deductions[field_name] = deduction;
  var remaining = philhealth_budget;
  for (var i in philhealth_deductions) {
    remaining -= philhealth_deductions[i];
  }

 $("#remaining-philhealth span").html(remaining);
  $(".philhealth_total").html(philhealth_budget-remaining);
}

function updateBalance(currentBalance) {
  $("#remaining-philhealth-balance span").html(currentBalance);
}

我希望在不刷新页面的情况下更新余额。

尝试一下

function updateRemaining(field_name, deduction) {
philhealth_deductions[field_name] = deduction;
  var remaining = philhealth_budget;
  for (var i in philhealth_deductions) {
    remaining -= philhealth_deductions[i];
  }

// give this id to your span "remaining-philhealth-span"
 document.querySelector('#remaining-philhealth-span').innerHTML = remaining;
 document.querySelector('.philhealth_total').innerHTML = philhealth_budget-remaining
 updateBalance(remaining)
}

function updateBalance(currentBalance) {
// give this id to your span "remaining-philhealth-balance-span"
document.querySelector('#remaining-philhealth-balance-span').innerHTML = currentBalance
}
