ThinkPHP framework,

When there is such a page, click the button to switch the content in the box and use ajax to request a specified page in the background (use the smarty template to render the specified template file and return the html string filling ), is it highly efficient to directly access the corresponding action and Method (rendering the specified template file) using ifarme?


------ Solution --------------------
There is no difference in efficiency, but there is a difference in effectiveness
Iframe can be rendered at will
Pay attention to the effect of the appended style sheet on the whole of ajax.
------ Solution --------------------
It is better to fill the template with iframe directly, so that the interface can be controlled through html, and the server side reduces the trouble of designing the template.
