Django表单提交后，如何获取相同name的不同value值

来源：互联网发布：成都软件编辑：程序博客网时间：2024/04/30 16:22

i前端：nput_test.html

<!DOCTYPE html><html><head lang="en">    <meta charset="UTF-8">    <title>Search</title>    <script>    </script></head><body>    <div><p>{{ result }}</p></div>    <form action="" method="post">{% csrf_token %}        <input type="text" name="key">        <input type="text" name="key">        <input type="submit" value="Search" >    </form></body></html>

两个<input >标签name都是'key'

后台：Django views.py

def setting(request):    if request.method == 'POST':        result_list = request.POST.getlist('key', '')        result = str(result_list)        return render_to_response('input_test.html', locals(), context_instance=RequestContext(request))    else:        return render_to_response('input_test.html', locals(), context_instance=RequestContext(request))

运行后，在浏览器表单中输入：

打开chrome ，提交表单，看FormData,其实浏览器已经向后台提交了两个name 为'key '的值。

后台也成功接收到一个列表 ['1', '2']。

主要是这个API request.POST.getlist(),可以接收到所有共享同一个name的value，

QueryDict.getlist(key, default)¶    Returns the data with the requested key, as a Python list. Returns an empty list if the key doesn’t exist and no default value was provided. It’s guaranteed to return a list of some sort unless the default value was no list.
