如果输入字段为空，如何重新加载页面

function reloadPageIfInputEmpty() {
  var inputField = document.getElementById("inputField"); // 假设输入字段的id为inputField
  if (inputField.value === "") {
    location.reload();
  }
}

<form onsubmit="return checkInputAndReloadPage()">
  <input type="text" id="inputField" name="inputField">
  <input type="submit" value="提交">
</form>

<script>
function checkInputAndReloadPage() {
  var inputField = document.getElementById("inputField"); // 假设输入字段的id为inputField
  if (inputField.value === "") {
    location.reload();
    return false; // 取消表单提交
  }
  return true; // 允许表单提交
}
</script>
