function submit_()

var json = "";

var formdata = document.getElementById("test_form")

for (i = 0; i < formdata.length-2; i++)

var key = formdata[i].name;

console.log(key);

json = json + "'" + key + "'"+":";

if (formdata[i].value == null || formdata[i].value == "")

var value = formdata[i].value;

json = json + "'" + null + "'" + ",";

else

var value = formdata[i].value;

json = json + "'" + value + "'" + ",";

json = json + "";

console.log(json);

$.ajax(

url: "/body/submit",

type: 'post',

data: formdata:json,

success: function (data)

if (data == true)

console.log("添加成功");

);
