To get the value of the data-videoid attribute in the iframe element using JavaScript, you can use the following code:

// get iframe element using its id
var iframe = document.getElementById("your-iframe-id");

// get the value of the data-videoid attribute
var dataVideoid = iframe.getAttribute("data-videoid");

// do something with the data-videoid value
console.log(dataVideoid);

Replace your-iframe-id with the actual id of the iframe in your page. This code will retrieve the iframe element using its id and then use the getAttribute() method to retrieve the value of the data-videoid attribute. You can then use this value as needed in your code
