Javascript 如何将名称值对象推送到数组中？

我正在尝试使用jQuery实现一个小ajax表单

我的简化表单如下所示，我给所有输入和文本区域class=“form\u one\u inputs”：

我可以循环浏览所有输入和文本区域，如下所示：

$('.form_one_inputs').each(function(index, obj){
     alert(index + " : " + obj.value +  ":" + obj.name);
     //
     // need to add each input to formData object
 });

如何将代码概括为将class=“form\u one\u inputs”的所有元素放入formData对象中。我一直在尝试，但在formData.push（）方面没有成功

请记住，这不适用于所有输入类型（即不使用val（）的输入类型）

试着这样做：

$('.form_one_inputs').each(function(){
    var item = $(this);
    alert("name:" + item.attr('name') + " value:" + item.val());
 });

要将所有项添加到formData对象，请使用以下方法：

var formData = {}; 
$('.form_one_inputs').each(function(){
    var item = $(this);
    formData[item.attr('name')] = item.val();
 });

如果要将表单中的所有元素序列化为JSON格式，请使用以下函数：

var jsonSerializer = function (form) {
    var data = {};
    var items = form.serializeArray();
    for (var i = 0; i < items.length; i++)
       data[items[i].name] = items[i].value;
       return data;
};

var formData = jsonSerializer($('form'));

var jsonSerializer=函数（表单）{
变量数据={}；
var items=form.serializeArray（）；
对于（变量i=0；i

这样，您就不需要知道输入的名称，请尝试以下代码：

$('.form_one_inputs').each(function(index, obj){
     alert(index + " : " + obj.value +  ":" + obj.name);
     formData.append(obj.name, obj.value);
 });

像这样

(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){
            if(push_counters[key] === undefined){
                push_counters[key] = 0;
            }
            return push_counters[key]++;
        };

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

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

            var k,
                keys = this.name.match(patterns.key),
                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);

var myobj = $('.form_one_inputs').serializeObject();

…您正在尝试使用推送。推送用于阵列。在本例中，您需要创建一个散列，其中键是输入的名称，值是输入的值

var formData = {};
$('.form_one_inputs').each(function(index, obj){
  formData[obj.name] = obj.value
});

您是否尝试使用表单序列化
