Answer 1

在web开发过程中，经常遇到将form序列化不能格式的字符串提交到后台，下面就介绍怎样将form表单序列化为json字符串。
//序列话
$.fn.serializeObject = function()
{
var o = {};
var a = this.serializeArray();
$.each(a, function() {
if (o[this.name]) {
if (!o[this.name].push) {
o[this.name] = [o[this.name]];
}
o[this.name].push(this.value || '');

function addPersonInfo(){
//序列化form
var data = $('#personInfo').serializeObject();
$.ajax({
type:"post",

data:JSON.stringify(data),
contentType: "application/json;charset=utf-8",
