如何序列化表单数据

    $.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;        };

调用该函数如下：

dataArray = $("form").serializeObject();
