前端是一个带图片上是图片上传的form，想用AJAX上传到后台保存
<form action="{% url '**'%}" method="POST" enctype="multipart/form-data">
<div class="form-group">
<div class="container">
<div class="row">
<div class="col-sm-12 col-md-2 " >
<label >Mate40Pro</label>
<select id='is_show' class="form-control" name="is_show">
<option value="showed">已上样</option>
<option value="noshowd">未上样</option>
</select>
</div>
<div class="col-sm-12 col-md-2 " >
<label >上样照片</label><input name='phone_pic' type="file">
</div>
</div>
</div>
<input type='submit' value='提交'>
</form>django model部分就两个字段
phone_pic=models.filefeild(uploadto='pic')
is_show=models.charfield(max_lenght=40)ajax 和后台Views部分，主要是图片上传那个，写了好久，各种错误。。。心累。。怎么搞啊。。。谢谢
<form action="{% url '**'%}" method="POST" enctype="multipart/form-data">

<div class="row">

<div class="col-sm-12 col-md-2 " >
<label >上样照片</label><input name='phone_pic' type="file" id="file">
</div>
</div>
</div>
<input type='submit' value='提交' id="submit">
</form>
<script>
window.onLoad = function() {
var Asubmit = document.getElementById('submit')
var fileList = document.getElementById('file')[0].files
Asubmit.onclick = function() {
var formData = new FormData();
for (var i = 0; i< fileList.length; i++) {
formData.append('files', fileList[i])
}
formData.append('其他参数'，val)
// 下面写ajax
ajax里面的data 传formData
}
}
</script>总得来说就是通过formData 来传递参数，希望对你能有帮助

后端就是一个接口，你自己应该也写好了。看下我注释应该可以明白。
