detect right-click or mouse event on different domain iframe that is very hard , if people want to use right-click, probabaly, he dosen't want click any ads. So if u just want to the right-click to not affect your content action or movement, just use mousemove on body to clean up all action...

Detecting a mouse right-click on an `<iframe>` source from Google's advertising network (e.g., AdSense) without using a proxy server or any external APIs is challenging, if not impossible, due to the complexity of modern web security measures. However, I can provide you with some potential approaches and considerations:

**1. Mouse event tracking:**

You can use JavaScript to track mouse events on the `<iframe>` element. When the user right-clicks on the iframe's source, you might be able to detect this event using the `mousedown` or `contextmenu` events.

Here's an example:
```javascript
const iframe = document.querySelector('iframe');

iframe.addEventListener('mousedown', (event) => {
if (event.button === 2 && event.target.classList.contains('google-ads')) { // Right-click detected on Google AdSense iframe source
console.log('Right click detected!');
}
});

iframe.addEventListener('contextmenu', (event) => {
if (event.button === 2 && event.target.src.includes('.google.com')) { // Right-click detected on Google AdSense iframe source
console.log('Right click detected!');
}
});
```
However, this approach may not work reliably, as the `mousedown` and `contextmenu` events can be triggered by other elements or by keyboard shortcuts (e.g., right-clicking on a context menu).

**2. CSS pseudo-element:**

You can use CSS to add a pseudo-element to the `<iframe>` element that can detect the right-click event.

```css
iframe {
position: relative;
}

iframe::after {
content: '';
display: block;
width: 0;
height: 0;
border-top: 1px solid transparent;
border-bottom: 1px solid #fff; /* pseudo-element styles */
}
```
Then, use JavaScript to listen for the `click` event on the iframe's pseudo-element:
```javascript
const iframe = document.querySelector('iframe');

iframe.addEventListener('click', (event) => {
if (event.target === iframe.querySelector(':after')) { // Right-click detected on Google AdSense iframe source
console.log('Right click detected!');
}
});
```
Again, this approach may not work reliably, as the pseudo-element might be triggered by other elements or by keyboard shortcuts.

**3. Cross-origin resource sharing (CORS):**

If you can modify the `<iframe>` element's `src` attribute to include a special parameter that identifies it as a Google AdSense iframe, you might be able to detect right-clicks using CORS.

For example:
```javascript
const iframe = document.querySelector('iframe');

if (window.location.search.includes('?ads=1')) { // Google AdSense iframe detected
iframe.addEventListener('click', (event) => {
if (event.button === 2 && event.target.classList.contains('google-ads')) { // Right-click detected on Google AdSense iframe source
console.log('Right click detected!');
}
});
}
```
However, this approach relies on the user visiting a page with the `?ads=1` parameter, which may not be a reliable way to detect right-clicks.

**Conclusion:**

Detecting mouse right-clicks on an `<iframe>` source from Google's advertising network without using a proxy server or any external APIs is challenging. The approaches mentioned above have limitations and may not work reliably in all cases.

If you need to detect such events, I recommend exploring other methods, such as:

1. Using a library like `google-analytics` to track user behavior.
2. Implementing a custom tracking solution using Google's Ads API (if available).
3. Modifying the `<iframe>` element's HTML structure or CSS styles to include specific identifiers.

Before investing time in developing a solution, consider whether there are other ways to achieve your goals that don't rely on detecting right-click events on an iframe source.

Detecting a mouse right-click on an `<iframe>` with a Google Ads source from a different domain can be a bit challenging due to same-origin policy restrictions. Here's a step-by-step guide on how to achieve this using JavaScript:

**Prerequisites**

* You have access to the HTML and JavaScript files of the webpage that contains the `<iframe>`.
* The Google Ads source URL is known (or can be obtained dynamically).

**Step 1: Add an event listener to the iframe**

Wrap your `<iframe>` with a container element, e.g., `div`, and add an event listener to it. This will allow you to capture mouse events on the container element, which includes the mouse right-click event.
```html
<div id="ads-container">
<iframe src="https://example.com" frameborder="0"></iframe>
</div>
```
**Step 2: Create a function to detect mouse right-click**

Create a JavaScript function that will be triggered when a mouse right-click event is detected on the container element. This function can check if the iframe's `src` attribute matches the expected Google Ads source URL.
```javascript
function onRightClick(event) {
const target = event.target;
const iframeSrc = target.querySelector('iframe').getAttribute('src');

// Check if the iframe's src matches the expected Google Ads source URL
if (iframeSrc === 'https://ads.example.com') {
console.log('Mouse right-click detected on Google Ads iframe!');
// Additional logic can be added here, e.g., sending a notification or performing an action.
}
}

// Add event listener to the container element
document.getElementById('ads-container').addEventListener('contextmenu', onRightClick);
```
**Step 3: Handle cross-domain issues**

Since same-origin policy restrictions may prevent you from accessing the iframe's `src` attribute directly, you'll need to use a workaround. One approach is to create a proxy server that can make requests to the iframe's src URL and return the response to your JavaScript code.

You can use a library like Axios or fetch API to make requests to the proxy server.
```javascript
// Create an instance of Axios or fetch API
const axios = require('axios');

function onRightClick(event) {
const target = event.target;
const iframeSrc = 'https://your-proxy-server.com/iframe-src';

// Make a request to the proxy server
axios.get(iframeSrc)
.then(response => {
const iframeSrcValue = response.data;

if (iframeSrcValue === 'https://ads.example.com') {
console.log('Mouse right-click detected on Google Ads iframe!');
// Additional logic can be added here, e.g., sending a notification or performing an action.
}
})
.catch(error => {
console.error(error);
});
}
```
**Step 4: Implement the proxy server**

Create a simple proxy server that listens for requests to the iframe's src URL and returns the expected response. You can use Node.js, Express.js, or another web framework to implement this.
```javascript
const express = require('express');
const app = express();

app.get('/iframe-src', (req, res) => {
const iframeSrc = req.query.src;
if (iframeSrc === 'https://ads.example.com') {
res.send(iframeSrc);
} else {
res.status(404).send('Not found');
}
});

app.listen(3000, () => {
console.log('Proxy server listening on port 3000');
});
```
By following these steps, you can detect mouse right-clicks on an `<iframe>` with a Google Ads source from a different domain using JavaScript.
