~~~
1.接收頁面上的圖片對象，要是用files/
通過id獲取document.getElementById('img').files[0]
2.傳遞的時候，由于圖片是對象，所以這里不能使用一般的字典保存，要創建new FormData()對象，通過append方法來保存
3.結尾的時候需要用設置兩個值processData:false,contentType:false
~~~
>[danger] ##### js 寫法
~~~
function  file() {
    {#獲取圖片對象#}
    var img = document.getElementById('img').files[0]

    {#保存數據，可以保存對象#}
    var data = new FormData()
    {#添加數據#}
    data.append("kv","va");
    data.append("k1",img)
    $.ajax({

        url:'/index/',
        type:'POST',
        data:data,
        success:function (arg) {
            console.log(arg)
        },
        processData:false,
        contentType:false
    })
};
