我最近尝试在select2应用中使用django多选框，select2框显示正确，可以选择多个选项，但有一个问题当选定的值放入数组时，
这是我的代码：
html页面：
<head>
<link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.10/css/select2.min.css" rel="stylesheet" />
<script src="{% static 'js/vendor/jquery-3.4.1.min.js' %}"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.10/js/select2.min.js"></script>
<script>
$(document).ready(function() {
$('.recipientMultiSelect').select2({
placeholder: "Choose Recipient Numbers / Groups",tags: true
});
});
</script>
</head>
<body>
<form action="{% url 'broadcast_single' %}" method="POST">
{% csrf_token %}
<div class="col-md-4">
<div class="form-group">
<label for="broadcast_name" class="col-form-label"> Broadcast Name: </label>
<input type="text" name="broadcast_name" class="form-control" required>
</div>
</div>
<div class="col-md-4">
<div class="form-group">
<label for="recipients[]" class="col-form-label"> Recipient List: </label>
<select class="recipientMultiSelect form-control" name="recipients[]" multiple="multiple" required>
<option value="aaaaaa">aaaaaa</option>
<option value="bbbbbb">bbbbbb</option>
<option value="cccccc">cccccc</option>
</select>
</div>
</div>
</br>
</br>
</br>
</br>
<div class="col-xs-8 col-md-8">
<div class="form-group">
<label for="broadcast-content" class="col-form-label"> SMS Content: </label>
<textarea name="broadcast_content" rows="15" cols="85" maxlength="160" class="form-control"> </textarea>
</div>
</div>
<div class="col-xs-8 col-md-8">
<div class="form-group">
<button class="btn btn-primary btn-block mt-4" type="submit">Send Broadcast</button>
</div>
</div>
</form>
</body>
让我们假设所有3个选项均已选中并传递到数组recipients[]
views.py：
def broadcastSingle(request):
if request.method == 'POST':
bcName = request.POST['broadcast_name']
bcRecArray = request.POST['recipients[]']
bcContent = request.POST['broadcast_content']
print('PRINT : ',len(bcRecArray))
print(','.join(bcRecArray))
bcRecArray应包含['aaaaaa'，'bbbbbb'，'cccccc']，长度应为3
但是，bcRecArray具有['c'，'c'，'c'，'c'，'c'，'c']和长度为6
我认为，select2多选框仅采用了最后一个选定的值，并将其转换为选定值中的字母数组。
