    {% extends 'base.html' %}
    {% block content %}
        <form action="" method="post" class="form-group" enctype="multipart/form-data">
        {% csrf_token %}

                        <label for="myfile">头像
                            <img src="/media/{{ request.user.avatar }}" alt="" width="80" style="margin-left: 10px" id="myimg">
                        </label>
                        <input type="file" id="myfile" name="avatar" style="display: none">
                    </div>
            <input type="submit" class="btn btn-success">
        </form>
    
    {% endblock %}
    
    {% block js %}
        <script>
        $('#myfile').change(function () {
            // 文件阅读器
            //1 产生一个文件阅读器对象
            var fileReader = new FileReader();
            //2 获取用户上传的文件
            var fileObj = $(this)[0].files[0];
            //3 让文件阅读器读取该文件
            fileReader.readAsDataURL(fileObj);  // 这一步是异步 提交完之后直接运行下一行
            //4 利用文件阅读器将文件展示出来
            fileReader.onload = function () {
                $('#myimg').attr('src', fileReader.result)
            }
        });
        </script>
