Go language: Elegant template cutting technology

This is a creation in Article, where the information may have evolved or changed.

As is known to all, a Web page is generally composed of head, body, and feet, and a project in which the heads and feet are basically the same, these parts need to be extracted.

Like what:

 

 
 
When split, it is divided into this:
 
Head:
 
 
Body
 
...
 
Feet:
 
</body> ...
 
You can then render the template by invoking the Func (*template) Execute method three times!
 

 
 
But I have an obsessive-compulsive disorder, see 
 
Main.html:
 
{{define "main"}}
 
Index.html:
 
{{Template ' main '.}} {{define "content"}} ... {{End}}
 
The 
 then uses  func parsefiles (filenames. String) (*template, error) to pass in the above two file names at once, calling  func (*template) Execute will be able to achieve the goal. Note Two files {{Template xxx.}} There is a point, otherwise the data cannot be passed in!
