ASP tip: Use function InStrRev () to get the current file name

The InStrRev function, starting from the last search of the string, preceded by a string.

For example, its application:

The following are the referenced contents: <% Dim Strtxt,pos strtxt= "Www.webjx.com" Pos=instrrev (Strtxt, ".") Response.Write Pos %>

The start of our search is in reverse order, from a point before COM. The length of the starting character, with this point, a total of 10 characters, returns the result will be 9.

By this principle, we can get the filename, domain name suffix name, and so on.

The following are the referenced contents: <% Dim AA,BB,CC,DD Aa=request.servervariables ("url") Bb=instrrev (AA, "/") Cc=len (AA) Dd=right (AA,CC-BB) Response.Write DD %>
