## Getting Started
|
|
|
|
|
|
|
|
The following code shows an example of how to use paginater:
|
|
|
|
|
|
|
|
```go
|
|
|
|
package main
|
|
|
|
|
|
|
|
import "github.com/Unknwon/paginater"
|
|
|
|
|
|
|
|
func main() {
|
|
|
|
// Arguments:
|
|
|
|
// - Total number of rows
|
|
|
|
// - Number of rows in one page
|
|
|

|

|
|
|
p := paginater.New(45, 10, 3, 3)
|
|
|
|
|
|
|
|
// Then use p as a template object named "Page" in "demo.html"
|
|
|
|
// ...
|
|
|
|
}
|
|
|
|
```
|
|
|
|
|
|
|
|
`demo.html`
|
|
|
|
|
|
|
|
```html
|
|
|
|
{{if not .Page.IsFirst}}[First](1){{end}}
|
|
|
|
{{if .Page.HasPrevious}}[Previous]({{.Page.Previous}}){{end}}
|
|
|
|
|
|
|
|
{{range .Page.Pages}}
|
|
|
|
{{if eq .Num -1}}
|
|
|
|
...
|
|
|
|
{{else}}
|
|
|
|
{{.Num}}{{if .IsCurrent}}(current){{end}}
|
|
|
|
{{end}}
|
|
|
|
{{end}}
|
|
|
|
|
|
|
|
{{if .Page.HasNext}}[Next]({{.Page.Next}}){{end}}
|
|
|
|
{{if not .Page.IsLast}}[Last]({{.Page.TotalPages}}){{end}}
|
|
|
|
```
|
|
|
|
|
|
|
|
Possible output:
|
|
|
|
|
|
|
|
```
|
|
|
|
[First](1) [Previous](2) ... 2 3(current) 4 ... [Next](4) [Last](5)
|
|
|
|
```
|
|
|
|
|
|
|
|
As you may guess, if the `Page` value is `-1`, you should print `...` in the HTML as common practice.
