# Does hashnode widget support Javascript

First let's make a simple widget named \`alert\`:

```javascript
<script>
console.log('hello from widget');

let count = 0;

function click_button(){
	let str = `click button from widget ${++count} times`;
	console.log(str);
	document.getElementById("demo").innerHTML = str;
	alert(str);
}
</script>
<style>
button {
    padding: 5px 10px;
}
</style>
<p id="demo"></p>
<button onclick="click_button()">click to alert</button>
```

Then add it to article:

```plaintext
%%[alert]
```

%%[alert] 

It's proven that Javascript is allowed but `alert` function doesn't work. Can you see an alert dialog?
