如何将下载按钮的值放入我的django视图？

<form method="post" action="{% url 'download_view' %}">
  {% csrf_token %}
  <input type="hidden" name="download_value" id="download_value">
  <button type="submit" onclick="setDownloadValue()">下载</button>
</form>

<script>
  function setDownloadValue() {
    var downloadValue = "下载按钮的值"; // 替换为实际的下载按钮的值
    document.getElementById("download_value").value = downloadValue;
  }
</script>

from django.shortcuts import render

def download_view(request):
    if request.method == 'POST':
        download_value = request.POST.get('download_value')
        # 在这里处理下载按钮的值
        # 可以根据下载按钮的值执行相应的操作
        # 例如，根据不同的值返回不同的文件或执行不同的逻辑
        return render(request, 'download.html', {'download_value': download_value})
    else:
        return render(request, 'download.html')
