我发现Tobias Cohen的代码有一个问题（我没有足够的分数来直接评论它），否则它对我来说是有效的。如果您有两个同名的选择选项，都是value=“”，原始代码将生成“name”：“”而不是“name”:[”，“”]

我认为这可以通过在第一个if条件中添加“||o[this.name]==''”来解决：

$.fn.serializeObject = function()
{
    var o = {};
    var a = this.serializeArray();
    $.each(a, function() {
        if (o[this.name] || o[this.name] == '') {
            if (!o[this.name].push) {
                o[this.name] = [o[this.name]];
            }
            o[this.name].push(this.value || '');
        } else {
            o[this.name] = this.value || '';
        }
    });
    return o;
};

Javascript/jQuery一行代码-也适用于旧版本（ES6之前）：

$('form').serializeArray().reduce((f,c) => {f[c['name']]=(f[c['name']])?[].concat(f[c['name']],c['value']):c['value']; return f}, {} );

此代码转换并保存输入类型，而不是全部转换为字符串：

jQuery.fn.serializeForm = function () {
    var form = this.get(0);
    var i = [];
    var ret = {};
    for (i = form.elements.length - 1; i >= 0; i = i - 1) {
        if (form.elements[i].name === "") {
            continue;
        }
        var name = form.elements[i].name;
        switch (form.elements[i].nodeName) {
            case 'INPUT':
                switch (form.elements[i].type) {
                    case 'text':
                    case 'tel':
                    case 'email':
                    case 'hidden':
                    case 'password':
                        ret[name] = encodeURIComponent(form.elements[i].value);
                        break;
                    case 'checkbox':
                    case 'radio':
                        ret[name] = form.elements[i].checked;
                        break;
                    case 'number':
                        ret[name] = parseFloat(form.elements[i].value);
                        break;
                }
                break;
            case 'SELECT':
            case 'TEXTAREA':
                ret[name] = encodeURIComponent(form.elements[i].value);
                break;
        }
    }
    return ret;
};

例如，这是输出：

Day: 13
Key: ""
Month: 5
OnlyPayed: true
SearchMode: "0"
Year: 2021

而不是

Day: "13"
Key: ""
Month: "5"
OnlyPayed: "true"
SearchMode: "0"
Year: "2021"

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;

})();

如果要发送带有JSON的表单，则必须在发送字符串时删除[]。您可以使用jQuery函数serializeObject（）实现这一点：

var frm = $(document.myform);
var data = JSON.stringify(frm.serializeObject());

$.fn.serializeObject = function() {
    var o = {};
    //var a = this.serializeArray();
    $(this).find('input[type="hidden"], input[type="text"], input[type="password"], input[type="checkbox"]:checked, input[type="radio"]:checked, select').each(function() {
        if ($(this).attr('type') == 'hidden') { //If checkbox is checked do not take the hidden field
            var $parent = $(this).parent();
            var $chb = $parent.find('input[type="checkbox"][name="' + this.name.replace(/\[/g, '\[').replace(/\]/g, '\]') + '"]');
            if ($chb != null) {
                if ($chb.prop('checked')) return;
            }
        }
        if (this.name === null || this.name === undefined || this.name === '')
            return;
        var elemValue = null;
        if ($(this).is('select'))
            elemValue = $(this).find('option:selected').val();
        else
            elemValue = this.value;
        if (o[this.name] !== undefined) {
            if (!o[this.name].push) {
                o[this.name] = [o[this.name]];
            }
            o[this.name].push(elemValue || '');
        }
        else {
            o[this.name] = elemValue || '';
        }
    });
    return o;
}
