how to enter dynamic data to a javascript function after page load

There are a few different ways you can enter dynamic data into a JavaScript function after the page has loaded. Here are a few options you can consider:

1. Use a global variable: You can define a global variable in your JavaScript code and then update its value with the dynamic data. The function can then access the global variable to get the dynamic data.
2. Pass the dynamic data as an argument to the function: You can define a function that takes one or more arguments, and then call the function with the dynamic data as the argument(s).
3. Use a form input element: You can use a form input element (such as a text field or select box) to allow the user to enter the dynamic data. You can then use JavaScript to get the value of the input element and pass it to the function.
4. Use an AJAX request: You can use an AJAX request to fetch the dynamic data from the server and then pass it to the function. This can be useful if the dynamic data is not available on the client side and needs to be retrieved from the server.
