<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0/dist/js/bootstrap.min.js"></script>

<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#myModal">
  发布数据
</button>

<div class="modal fade" id="myModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">发布数据</h5>
        <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
      </div>
      <div class="modal-body">
        <form id="myForm">
          <div class="mb-3">
            <label for="dataInput" class="form-label">数据</label>

        <button type="button" class="btn btn-primary" onclick="submitData()">提交</button>
      </div>
    </div>
  </div>
</div>

function submitData() {
  var data = document.getElementById("dataInput").value;
  
  // 使用ajax将数据提交到后端
  $.ajax({
    url: "后端接口地址",
    type: "POST",
    data: { data: data },
    success: function(response) {
      // 处理成功响应
      console.log(response);
      // 关闭模态框
      $("#myModal").modal("hide");
    },
    error: function(xhr, status, error) {
      // 处理错误响应
      console.log(error);
    }
  });
}
