使用FormData对象

1.创建一个FormData空对象，然后使用append方法添加key/value

var formdata = new FormData();  
formdata.append('name','fdipzone');  
formdata.append('gender','male');

2.取得form对象，作为参数传入到FormData对象

<form name="form1" id="form1">  
<input type="text" name="name" value="fdipzone">  
<input type="text" name="gender" value="male">  
</form>

var form = document.getElementById('form1');  
var formdata = new FormData(form);

使用FormData提交表单及上传文件：

            type: 'POST',  
            data: data,  
            dataType: 'JSON',

                $('#result').html(result);  
            }else{  
                alert('提交失敗');  
            }

    $response['isSuccess'] = true;  
    $response['name'] = $name;  
    $response['gender'] = $gender;  
    $response['photo'] = $filename;

    $response['isSuccess'] = false;

                    }
                }
            })
        }

序列化表单提交jquery方法（

serializeArray()

        let c = $('#submit').serializeArray();
        console.log(c);
        let datas = {};
        c.forEach((value, key) => {
            // datas.set(value.name,value.value);
            datas[value.name] = value.value;
        });

生成data数据对象后提交即可用foreach方法转变结构
