这里有一种非jQuery方法：

    var getFormData = function(form) {
        //Ignore the submit button
        var elements = Array.prototype.filter.call(form.elements, function(element) {
            var type = element.getAttribute('type');
            return !type || type.toLowerCase() !== 'submit';
        });

您可以这样使用：

function() {

    var getFormData = function(form) {
        //Ignore the submit button
        var elements = Array.prototype.filter.call(form.elements, function(element) {
            var type = element.getAttribute('type');
            return !type || type.toLowerCase() !== 'submit';
        });

        //Make an object out of the form data: {name: value}
        var data = elements.reduce(function(data, element) {
            data[element.name] = element.value;
            return data;
        }, {});

        return data;
    };

    var post = function(action, data, callback) {
        var request = new XMLHttpRequest();
        request.onload = callback;
        request.open('post', action);
        request.setRequestHeader("Content-Type", "application/json;charset=UTF-8");
        request.send(JSON.stringify(data), true);
        request.send();
    };

    var submit = function(e) {
        e.preventDefault();
        var form = e.target;
        var action = form.action;
        var data = getFormData(form);
        //change the third argument in order to do something
        //more intersting with the response than just print it
        post(action, data, console.log.bind(console));
    }

    //change formName below
    document.formName.onsubmit = submit;

})();

Use:

function form_to_json (selector) {
  var ary = $(selector).serializeArray();
  var obj = {};
  for (var a = 0; a < ary.length; a++) obj[ary[a].name] = ary[a].value;
  return obj;
}

输出：

{"myfield": "myfield value", "passwordfield": "mypasswordvalue"}

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);

此代码适用于我：

  var data = $('#myForm input, #myForm select, #myForm textarea').toArray().reduce(function (m, e) {
            m[e.name] = $(e).val();
            return m;
        }, {});

所有这些答案对我来说似乎都太过头了。为了简单起见，有些话要说。只要您的所有表单输入都设置了name属性，这应该只适用于jimdandy。

$（'form.myform'）.submit（函数（）{var$this=$（this），viewArr=$this.serializeArray（），视图=｛｝；for（viewArr中的var i）{view[viewArr[i].name]=viewArr[i].value；}//在这里使用视图对象（例如JSON.stringify？）});

这是对Tobias Cohen函数的改进，该函数在多维数组中运行良好：

然而，这不是一个jQuery插件，但如果您想这样使用它，只需几秒钟就可以将它变成一个：只需替换函数声明包装器：

function serializeFormObject(form)
{
    ...
}

具有：

$.fn.serializeFormObject = function()
{
    var form = this;
    ...
};

我想这与梅斯克的解决方案相似，因为它做了相同的事情，但我认为这有点干净和简单。我还将macek的测试用例输入添加到小提琴中，并添加了一些额外的输入。到目前为止，这对我来说很好。

function serializeFormObject(form)
{
    function trim(str)
    {
        return str.replace(/^\s+|\s+$/g,"");
    }

    var o = {};
    var a = $(form).serializeArray();
    $.each(a, function() {
        var nameParts = this.name.split('[');
        if (nameParts.length == 1) {
            // New value is not an array - so we simply add the new
            // value to the result object
            if (o[this.name] !== undefined) {
                if (!o[this.name].push) {
                    o[this.name] = [o[this.name]];
                }
                o[this.name].push(this.value || '');
            } else {
                o[this.name] = this.value || '';
            }
        }
        else {
            // New value is an array - we need to merge it into the
            // existing result object
            $.each(nameParts, function (index) {
                nameParts[index] = this.replace(/\]$/, '');
            });

            // This $.each merges the new value in, part by part
            var arrItem = this;
            var temp = o;
            $.each(nameParts, function (index) {
                var next;
                var nextNamePart;
                if (index >= nameParts.length - 1)
                    next = arrItem.value || '';
                else {
                    nextNamePart = nameParts[index + 1];
                    if (trim(this) != '' && temp[this] !== undefined)
                        next = temp[this];
                    else {
                        if (trim(nextNamePart) == '')
                            next = [];
                        else
                            next = {};
                    }
                }

                if (trim(this) == '') {
                    temp.push(next);
                } else
                    temp[this] = next;

                temp = next;
            });
        }
    });
    return o;
}
