Iframe or load is used for the architecture design of web software

Q:The company wants to develop a small web software. My current idea is to imitate the 163 mailbox architecture, top + Left Navigation + main content display area. the problem is as follows: I am using the jquery library for development. Currently, I don't want to use iframe as the main content display area, but I want to use jquery. load () to load the page to the main content display area, but I am worried about jquery. load () Efficiency and versatility, for example, may be always in the loading state.

The effect I want to achieve is the same as that of ext. I don't know if this idea is feasible. Please kindly advise me. Thank you!

In addition, I studied the layout of the 163 mailbox and found that the content display area on the left is not the entire iframe, But div. Generally, if the iframe is embedded, right-click on the page to view the page information. You can see the accessed page address, but you cannot see the 163 email address. This means that it is not simply using iframe, and you do not know if it is used to load the page with js.

A: jquery. load () and iframe are no problem. In fact, many beautiful pop-up windows are implemented by div + iframe, and there is no need to start from the underlying layer. jquery has been well encapsulated, user experience is preferred.
