jquery form表单序列化为对象

$.fn.serializeObject = function() {    var o = {};    var a = this.serializeArray();    $.each(a, function() {        if (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;}
