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();
