如何在Fromhour和Fromminutes开始时启用按钮,在tohour和tomminutes结束时禁用按钮

我尝试使用if条件,但在几分钟的检查中失败了

else {
  <input type="submit" class="btn btn-info" name="submit" value="Submit Discount" disabled style="width:180px;" onchange="preventMultipleSave()" />
}
} else if (DateTime.Now.Hour == Model.FromTimeHour && DateTime.Now.Hour == Model.ToTimeHour) {
  if (DateTime.Now.Minute >= Model.FromTimeMinutes && DateTime.Now.Minute <= Model.ToTimeMinutes) {
    <input type="button" id="btn_save" style="width:auto" name="submit" value="Submit Discount" class="btn btn-info" onclick="SubmitForm()" />
    <input type="submit" id="btn_save1" name="submit" value="Submit Discount" style="display:none" />
  } else {
    <input type="submit" class="btn btn-info" name="submit" value="Submit Discount" disabled style="width:180px;" onchange="preventMultipleSave()" />
  }
} else if (DateTime.Now.Hour >= Model.FromTimeHour && DateTime.Now.Hour <= Model.ToTimeHour) {
  if (DateTime.Now.Minute >= Model.FromTimeMinutes && DateTime.Now.Minute <= Model.ToTimeMinutes) {
    <input type="button" id="btn_save" style="width:auto" name="submit" value="Submit Discount" class="btn btn-info" onclick="SubmitForm()" />
    <input type="submit" id="btn_save1" name="submit" value="Submit Discount" style="display:none" />
  } else if (DateTime.Now.Hour > Model.FromTimeHour && DateTime.Now.Hour == Model.ToTimeHour) {
    if (DateTime.Now.Minute <= Model.FromTimeMinutes && DateTime.Now.Minute <= Model.ToTimeMinutes) {
      <input type="button" id="btn_save" style="width:auto" name="submit" value="Submit Discount" class="btn btn-info" onclick="SubmitForm()" />
      <input type="submit" id="btn_save1" name="submit" value="Submit Discount" style="display:none" />
    } else {
      <input type="submit" class="btn btn-info" name="submit" value="Submit Discount" disabled style="width:180px;" onchange="preventMultipleSave()" />
    }
  } else {
    <input type="submit" class="btn btn-info" name="submit" value="Submit Discount" disabled style="width:180px;" onchange="preventMultipleSave()" />
  }
} else {
  <input type="submit" class="btn btn-info" name="submit" value="Submit Discount" disabled style="width:180px;" onchange="preventMultipleSave()" />
}

} else {
  <input type="submit" class="btn btn-info" name="submit" value="Submit Discount" disabled style="width:180px;" onchange="preventMultipleSave()" />
}

首先简化代码,然后使用条件

我没有研究按钮实际存在背后的逻辑。

如果你想使用JavaScript提交表单,我强烈建议重命名按钮。切勿将表单中的任何内容称为“提交”

@{
    bool isButtonEnabled = false;
    int currentHour = DateTime.Now.Hour;
    int currentMinute = DateTime.Now.Minute;

    // Check if current time is within the specified range
    if (currentHour > Model.FromTimeHour && currentHour < Model.ToTimeHour) {
        isButtonEnabled = true;
    } else if (currentHour == Model.FromTimeHour && currentMinute >= Model.FromTimeMinutes) {
        isButtonEnabled = currentHour != Model.ToTimeHour || currentMinute <= Model.ToTimeMinutes;
    } else if (currentHour == Model.ToTimeHour && currentMinute <= Model.ToTimeMinutes) {
        isButtonEnabled = true;
    }

    // Render the button based on isButtonEnabled
    if (isButtonEnabled) {
        <input type="button" id="btn_save" style="width:auto" name="submit" value="Submit Discount" class="btn btn-info" onclick="SubmitForm()" />
        <input type="submit" id="btn_save1" name="submit" value="Submit Discount" style="display:none" />
    } else {
        <input type="submit" class="btn btn-info" name="submit" value="Submit Discount" disabled style="width:180px;" onchange="preventMultipleSave()" />
    }
}
