DEVELOPING THE PAGE CONTENT
The user may customize the webpage to look however he/she likes by creating the entire HTML
content. Alternatively, the user can maintain the EM405-8 default look and feel of the webpage
by using the
l_em405web.lua
Lua library. This library contains a set of functions that can be
used to generate the main HTML structure that is used in the EM405-8’s default pages. By using
this library, the developer needs only to concentrate on the added content of the custom page.
The library l_em405web.lua includes four functions as summarized in Table IV. Details of each
function follow the table.
