Question

我有这个表单，用户输入详细信息，并使用提交按钮验证这些详细信息，这是HTML5的一项功能。现在我想要做的是当我点击提交按钮时按钮验证表格，如果一切正常，它会打开一个带有表格值的模态。

接下来，我希望用户重新检查，然后单击“确认”按钮，进一步验证表单。我无法做到这一点..这是我的代码..

<form action="/submit" id="form1">
  <table id="formTable">
    <tr>
      <td>
        <label for="stock">Stock Name : </label>
      </td>
      <td>
        <input type="text" name="stock" id="selectedStock" required class="typeahead" style="text-transform: uppercase;">
      </td>
    </tr>

    <tr>
      <td>
        <label for="action">BUY/SELL : </label>
      </td>
      <td style="text-align: left;">
        <select id="action">
          <option>BUY</option>
          <option>SELL</option>
        </select>
      </td>
    </tr>

    <tr>
      <td>
        <label for="quantity">Quantity : </label>
      </td>
      <td>
        <input type="number" name="quantity" id="selectedQuantity" required autocomplete="off">
      </td>
    </tr>

    <tr>
      <td>
        <label for="price">Price : </label>
      </td>
      <td>
        <input type="text" name="price" id="price" disabled required>
      </td>
    </tr>

    <tr>
      <td>
        <label>Total : </label>
      </td>
      <td style="text-align: left;">
        <span id="total"></span>
      </td>
    </tr>


  </table>
  <br/>
  <input type="submit" id="submit" value="Submit">
</form>

<div class="modal fade" id="submitModal">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button class="close" data-dismiss="modal">&times;</button>
        <h2 class="modal-title">Summary</h2>
      </div>
      <div class="modal-body">
        <div>
          <table style="margin: auto;" id="summaryTable">
            <tr>
              <td> NAME : </td>
              <td id="stockModal"></td>
            </tr>
            <tr>
              <td> BUY/SELL : </td>
              <td id="actionModal"></td>
            </tr>
            <tr>
              <td> QUANTITY : </td>
              <td id="quantityModal"></td>
            </tr>
            <tr>
              <td> PRICE : </td>
              <td id="priceModal"></td>
            </tr>
            <tr>
              <td> TOTAL : </td>
              <td id="totalModal"></td>
            </tr>
          </table>
        </div>
      </div>
      <div class="modal-footer">
        <button class="btn btn-success" id="confirmBtnModal">Confirm</button>
        <button class="btn btn-default close" data-dismiss="modal" id="closeBtnModal">Close</button>
      </div>
    </div>
  </div>
</div>

我的jquery就在这里..

var validation = true;
$("#form1").submit(function(e) {
  if (validation) {
    e.preventDefault();
    $("#submitModal").modal("show");
    gatherInfo();
  }
  $("#confirmBtnModal").click(function() {
    validation = false;
    $("#form1").submit();
  });
  if (validation == false)
    return true;

});

另外，如何检查我的表单是否已提交？ 在打开模态之前，只需单击提交按钮，浏览器就会给我一个错误，因为表单的操作设置为/submit。我猜它会在单击确认按钮时执行相同操作。

Answer 1

使用以下内容重写您的脚本部分，看看它是否有效，

var validation = true;

$("#submitBtnModal").on('click', function() {
    validation = false;
    $("#form1").submit();
  });

$("#form1").on('submit', function(e) {
  if (validation) {
    e.preventDefault();
    $("#submitModal").modal("show");
    gatherInfo();
  }
  if (validation == false)
    return true;

});

Answer 2

正如我评论的那样，如果您将$("#confirmBtnModal")更改为$("#submitBtnModal")，它应该可以正常工作

var validation = true;
$("#form1").submit(function(e) {
  if (validation) {
    e.preventDefault();
    $("#submitModal").modal("show");
    //
  }
  $("#submitBtnModal").click(function() {
    validation = false;
    $("#form1").submit();
  });
  if (validation == false)
    return true;

});
