Javascript验证日期脚本不起作用

标签： javascript html css

我遇到了一个错误，我的脚本无法在我的HTML文件上运行。此脚本用于确保如果日期大于今天，则不​​会接受提交日期的输入。但是，当我将脚本转移到另一个HTML文件时，它可以工作。它只适用于这个单独的HTML文件。

function checkform() {
  answ = validateDate(document.getElementById("doa").value);
  if (answ == false) {
    return false;
  } else {
    return true;
  }

}

function validateDate(doa) {
  var d = new Date(doa);
  var n = new Date();
  if (d >= n) {
    alert("Date cannot be greater than today.");
    return false;
  }
  return true;
}

我很想知道我的HTML文件出了什么问题导致脚本无法正常工作。谢谢。

你刚刚错误地关闭了标签。它应该是这样的：

<!--Particulars-->
<form action="feedbackresult.html" onsubmit="return checkForm()">
    <table class="form">
        <tbody>
            <tr>
                <td>
                    <label for="firstname">First Name: </label>
                </td>
                <td>
                    <input type="text" name="first" id="firstname">
                </td>
            </tr>
            <tr>
