此函数返回转换为正确类型的所有值；

bool/string/（integer/floats）可能

虽然您需要jQuery来实现这一点，但由于serializeArray也是jQuery，所以没什么大不了的。

/**
 * serialized a form to a json object
 *
 * @usage: $("#myform").jsonSerialize();
 *
 */

(function($) {
    "use strict";
    $.fn.jsonSerialize = function() {
        var json = {};
        var array = $(this).serializeArray();
        $.each(array, function(key, obj) {
            var value = (obj.value == "") ? false : obj.value;
            if(value) {
                // check if we have a number
                var isNum = /^\d+$/.test(value);
                if(isNum) value = parseFloat(value);
                // check if we have a boolean
                var isBool = /^(false|true)+$/.test(value);
                if(isBool) value = (value!=="false");
            }
            json[obj.name] = value;
        });
        return json;
    }
})(jQuery);

如果使用Undercore.js，可以使用相对简洁的：

_.object(_.map($('#myform').serializeArray(), _.values))

有什么问题：

var data = {};
$(".form-selector").serializeArray().map(function(x){data[x.name] = x.value;}); 

将任何东西变成对象（未经单元测试）

<script type="text/javascript">
string = {};

string.repeat = function(string, count)
{
    return new Array(count+1).join(string);
}

string.count = function(string)
{
    var count = 0;

    for (var i=1; i<arguments.length; i++)
    {
        var results = string.match(new RegExp(arguments[i], 'g'));
        count += results ? results.length : 0;
    }

    return count;
}

array = {};

array.merge = function(arr1, arr2)
{
    for (var i in arr2)
    {
        if (arr1[i] && typeof arr1[i] == 'object' && typeof arr2[i] == 'object')
            arr1[i] = array.merge(arr1[i], arr2[i]);
        else
            arr1[i] = arr2[i]
    }

    return arr1;
}

array.print = function(obj)
{
    var arr = [];
    $.each(obj, function(key, val) {
        var next = key + ": ";
        next += $.isPlainObject(val) ? array.print(val) : val;
        arr.push( next );
      });

    return "{ " +  arr.join(", ") + " }";
}

node = {};

node.objectify = function(node, params)
{
    if (!params)
        params = {};

    if (!params.selector)
        params.selector = "*";

    if (!params.key)
        params.key = "name";

    if (!params.value)
        params.value = "value";

    var o = {};
    var indexes = {};

    $(node).find(params.selector+"["+params.key+"]").each(function()
    {
        var name = $(this).attr(params.key),
            value = $(this).attr(params.value);

        var obj = $.parseJSON("{"+name.replace(/([^\[]*)/, function()
        {
            return '"'+arguments[1]+'"';
        }).replace(/\[(.*?)\]/gi, function()
        {
            if (arguments[1].length == 0)
            {
                var index = arguments[3].substring(0, arguments[2]);
                indexes[index] = indexes[index] !== undefined ? indexes[index]+1 : 0;

                return ':{"'+indexes[index]+'"';
            }
            else
                return ':{"'+escape(arguments[1])+'"';
        })+':"'+value.replace(/[\\"]/gi, function()
        {
            return "\\"+arguments[0]; 
        })+'"'+string.repeat('}', string.count(name, ']'))+"}");

        o = array.merge(o, obj);
    });

    return o;
}
</script>

测试输出：

$(document).ready(function()
{
    console.log(array.print(node.objectify($("form"), {})));
    console.log(array.print(node.objectify($("form"), {selector: "select"})));
});

on

<form>
    <input name='input[a]' type='text' value='text'/>
    <select name='input[b]'>
        <option>select</option>
    </select>

    <input name='otherinput[c][a]' value='a'/>
    <input name='otherinput[c][]' value='b'/>
    <input name='otherinput[d][b]' value='c'/>
    <input name='otherinput[c][]' value='d'/>

    <input type='hidden' name='anotherinput' value='hidden'/>
    <input type='hidden' name='anotherinput' value='1'/>

    <input type='submit' value='submit'/>
</form>

将产生：

{ input: { a: text, b: select }, otherinput: { c: { a: a, 0: b, 1: d }, d: { b: c } }, anotherinput: 1 }
{ input: { b: select } }

像boss一样将表单转换为JSON

$bower安装jquery序列化对象

以下代码现已弃用。

以下代码可以处理所有类型的输入名称；按照你的预期处理它们。

例如：

<!-- All of these will work! -->
<input name="honey[badger]" value="a">
<input name="wombat[]" value="b">
<input name="hello[panda][]" value="c">
<input name="animals[0][name]" value="d">
<input name="animals[0][breed]" value="e">
<input name="crazy[1][][wonky]" value="f">
<input name="dream[as][vividly][as][you][can]" value="g">

// Output
{
  "honey":{
    "badger":"a"
  },
  "wombat":["b"],
  "hello":{
    "panda":["c"]
  },
  "animals":[
    {
      "name":"d",
      "breed":"e"
    }
  ],
  "crazy":[
    null,
    [
      {"wonky":"f"}
    ]
  ],
  "dream":{
    "as":{
      "vividly":{
        "as":{
          "you":{
            "can":"g"
          }
        }
      }
    }
  }
}

用法

$('#my-form').serializeObject();

(function($){
    $.fn.serializeObject = function(){

        var self = this,
            json = {},
            push_counters = {},
            patterns = {
                "validate": /^[a-zA-Z][a-zA-Z0-9_]*(?:\[(?:\d*|[a-zA-Z0-9_]+)\])*$/,
                "key":      /[a-zA-Z0-9_]+|(?=\[\])/g,
                "push":     /^$/,
                "fixed":    /^\d+$/,
                "named":    /^[a-zA-Z0-9_]+$/
            };


        this.build = function(base, key, value){
            base[key] = value;
            return base;

        this.push_counter = function(key){

            }
            return push_counters[key]++;
        };

        $.each($(this).serializeArray(), function(){

            // Skip invalid keys
            if(!patterns.validate.test(this.name)){
                return;
            }

            var k,

                merge = this.value,
                reverse_key = this.name;

            while((k = keys.pop()) !== undefined){

                // Adjust reverse_key
                reverse_key = reverse_key.replace(new RegExp("\\[" + k + "\\]$"), '');

                // Push
                if(k.match(patterns.push)){
                    merge = self.build([], self.push_counter(reverse_key), merge);
                }

                // Fixed
                else if(k.match(patterns.fixed)){
                    merge = self.build([], k, merge);
                }

                // Named
                else if(k.match(patterns.named)){
                    merge = self.build({}, k, merge);
                }
            }

            json = $.extend(true, json, merge);
        });

        return json;
    };
})(jQuery);

serialize函数将JSON对象作为参数并返回serialize String。

function serialize(object) {
