JQuery扩展方法实现Form表单与Json互相转换；ajax提交表单

1.把表单转换出json对象

 

 //把表单转换出json对象
    $.fn.toJson = 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;
    };

 

　　

 

 

2.将josn对象赋值给form

 

//将josn对象赋值给form
    $.fn.loadData = function (obj) {
        var key, value, tagName, type, arr;

        this.reset();

        for (var x in obj) {
            if (obj.hasOwnProperty(x)) {
                key = x;
                value = obj[x];

                this.find("[name='" + key + "'],[name='" + key + "[]']").each(function () {
                    tagName = $(this)[0].tagName.toUpperCase();
                    type = $(this).attr('type');
                    if (tagName == 'INPUT') {
                        if (type == 'radio') {
                            if ($(this).val() == value) {
                                    $(this).attr('checked', true);
                            }
                        } else if (type == 'checkbox') {
                            arr = value.split(',');
                            for (var i = 0; i < arr.length; i++) {
                                if ($(this).val() == arr[i]) {
                                        $(this).attr('checked', true);
                                    break;
                                }
                            }
                        } else {
                            $(this).val(value);
                        }
                    } else if (tagName == 'SELECT' || tagName == 'TEXTAREA') {
                        $(this).val(value);
                    }
                });
            }
        }
    }

 

2.通过Jquery ajax提交表单

    $('#btn_submit').click(function (event) {

        if(!$('#form_node').valid())
        {
            return;
        }


        $(this).html('<i class="ace-icon fa fa-floppy-o  bigger-150"></i>正在提交');
        $(this).attr('disabled', true);//禁用表单提交按钮，避免重复提交


        // 获取表单数据
        var formData = $('#form_node').serialize();

        // 发送Ajax请求
        $.ajax({
            url: 'url',
            type: 'POST',
            data: formData,
            success: function (data) {
                // 处理服务器返回的数据
                console.log(data);
                
                $('#form_node')[0].reset();//清空表单数据

               //恢复表单提交按钮功能
                setTimeout(function () {
                    $('#btn_submit').attr('disabled', false);
                    $('#btn_submit').html('<i class="ace-icon fa fa-floppy-o  bigger-150"></i>保存');
                }, 2000);

            },
            error: function (jqXHR, textStatus, errorThrown) {
                // 处理请求失败的情况
                console.error(textStatus, errorThrown);

               //恢复表单提交按钮功能
                setTimeout(function () {
                    $('#btn_submit').attr('disabled', false);
                    $('#btn_submit').html('<i class="ace-icon fa fa-floppy-o  bigger-150"></i>保存');
                }, 2000);
            }
        });
    });　

 

服务端代码：

        [HttpPost]
        public async Task<IActionResult> AddNode(AreaInfo areaInfo)
        {
        }


        [HttpPost]
        public async Task<IActionResult> AddNode(string name,int age,string address......)
        {
        }
