将表单序列化成json，将json转换成字符串

//将表单序列化成json 字符串

$.fn.serializeObject = function(){

    var obj = {};

    var count = 0;

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

        var n = o.name, v = o.value;

        count++;

        obj[n] = obj[n] === undefined ? v

        : $.isArray( obj[n] ) ? obj[n].concat( v )

        : [ obj[n], v ];

    });

    obj.nameCounts = count + "";//表单name个数

    return JSON.stringify(obj);

};

var objectStr=$("#sysNumberRule-form-addNumberRule").serializeObject();

//转化为json对象

var objectJson=JSON.parse(objectStr);

将表单转换成url

            //将表单序列化成json 字符串

            $.fn.getFromValueToUrlStr = function(){

                var domain = this[0].action;

                var count = 0;

                var params = '';

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

                    var n = o.name, v = o.value.replace('&','%23');

                    count++;

                    if(v != ''){

                        params += '&' + n + '=' + v;

                    }

                });

                if(domain.indexOf('?') ==-1 ){

                    domain += "?";

                }

                if(domain.charAt(domain.length - 1) == '&'){

                    domain = domain.substring(0,domain.length - 1);

                }

                return domain + params;

            };
