Codeigniter ajax不显示html数据

//查看ajax，而不是从控制器返回数据。视图返回[object]，[object] ajax不会从控制器返回数据。视图返回[object]，[object]ajax不从控制器返回数据。视图返回[object]，[object]ajax不从控制器返回数据。视图返回[object]，[object]ajax不从控制器返回数据。视图返回[object]，[object]ajax不从控制器返回数据。视图返回[object]，[object]

您的模型函数总是返回FALSE，因为您无法获取数据，并且在每个循环中使用两次，一次在模型中，另一次在控制器中，这在代码中是错误的。是的

模型

控制器

您的型号代码在哪里？？并检查控制台显示的错误？？函数getvariance{$this->db->select'name，IFNULL quantity，0 AS quantity'；$q=$this->db->from'products'；if$q->num_rows>0{foreach$q->result AS$row{$data[]=$row；}返回$data；}返回FALSE；}请将此代码放在您的问题模型中。如果模型已经存在，您将无法获得数据库结果$q=$this->db->from'products'->get；您是否已将模型文件加载到构造函数$this->page_construct'products/update_price'，$meta，$output中；像这样吗？是的，在ajax中将数据转换成html表单时会出现问题
