# pvar（页面级变量）事件

> 场景：在商品详情页，设置“商品名称”、“商品品类”作为页面级变量。

**页面级变量配置方式示例**

| 标识符               | 名称   | 描述            |
| ----------------- | ---- | ------------- |
| skuName\_pvar     | 商品名称 | 商品名称          |
| skuCategory\_pvar | 商品品类 | 商品品类，例如裙子、鞋靴等 |

**对应的代码**

此示例中的页面级变量为“商品名称（skuName\_pvar）”、“商品品类（skuCategory\_pvar）”，在商品详情页面上设置了这两个页面级变量。

**数据验证方法**

在对应的应用（网站、Android 或者 iOS App）中打开设置了页面级变量的商品详情页，通过 Debugger 工具验证数据准确性

按照如下流程图验证

![](/files/-LrMeDMFQ2IUx6HD9Us1)

在本例中，如下图的数据请求说明打点代码生效

![](/files/-LrIN4zn1x-MXnmQ7epO)
