The first Html is sent from the background, usually embedded with a little bit of data, and then obtained by ajax.

Thank you for your invitation. It depends on your own needs, whether it isAjaxAsynchronous call orJsRead areaHtmlDepends on your business needs

Html is a static page with only some DOM containers. Js interacts with the background service through ajax. the background service interacts with the database, queries and returns the data required for loading the page. the front-end obtains the data and renders it to the page after processing.
