Linux script language PERL template application details-Linux general technology-Linux programming and kernel information, the following is a detailed description. A lot of similar HTML code is often used when compiling a PERL program. In this way, not only is it difficult to write, but once the page needs to be modified, and the program is very large, it will be more troublesome.
A good way to solve this problem is to use the template. There are two methods to use a template:
One is to extract fixed part of HTML code to generate a template file, and different parts are marked on the template. When generating the page, find the tag and replace it with the part you want to output.
The other is to extract the fixed part of HTML code as a function, and set parameters for different parts in the function. When a page is generated, the part to be output is passed as a parameter to the template function.
These two methods are basically the same, but the first method is to use DREAWEAVER, FRONTPAGE and other editing tools to modify the interface, which should be relatively simple. The second type of output display is more flexible. You can choose as needed.
The following two simple examples are used to introduce the basic usage of the template. It is expected to serve as an example.
Use the first method:
