# 管理弹出广告和全屏插页广告的频次限制
在创建或编辑 Popunder、桌面端/移动端 Fullpage Interstitial 广告位时，发布商可以选择启用/禁用 **频控** 用于其广告位。通过此选项，发布商可以决定在自身一侧管理频控（展示频率）。
**支持的广告格式：** Popunder、移动端 Popunder、桌面端全页插页广告、移动端全页插页广告。
## 设置
{% stepper %}
{% step %}
### 通过代码片段启用/禁用频控
在 Popunder 代码片段中禁用频控。 `capping_enabled` 还是 `ad_capping_enabled` 需要在广告代码片段中设置为 false
```js
```
```js
```
{% hint style="warning" %}
**注意：** 你需要完成第 2 步和第 3 步，以确保广告不会在每次点击时都触发。
{% endhint %}
{% endstep %}
{% step %}
### 设置事件监听器
需要为 creativeDisplayed 事件设置事件监听器，以便在发布商一侧存储/递增频控计数器
```js
```
{% endstep %}
{% step %}
### 管理页面 DOM
根据计数器的值（可采用任意方式存储），应将该代码片段排除在页面 DOM 之外。可通过前端或后端实现（两者示例如下）。
{% tabs %}
{% tab title="前端示例" %}
```html
示例页面
测试
```
{% endtab %}
{% tab title="后端示例" %}
```php
测试
测试
```
{% endtab %}
{% endtabs %}
{% endstep %}
{% endstepper %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.exoclick.com/publishers/zh/zhan-dian-yu-guang-gao-wei/manage-capping-popunder.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
