由于分页对象预定义的样式比较有限,有的时候我们想自定义分页的样式或者标签,由于分页对象的的所有属性和方法都是公开的,这便为开发者自定义分页样式提供了非常高的灵活度。开发者可以通过以下方式实现自定义分页内容:

  1. 对输出内容进行正则匹配替换实现自定义。
  2. 根据分页对象公开的属性和方法自行组织分页内容实现自定义。

自定义标签替换

package main

import (
	"github.com/gogf/gf/frame/g"
	"github.com/gogf/gf/net/ghttp"
	"github.com/gogf/gf/os/gview"
	"github.com/gogf/gf/text/gstr"
	"github.com/gogf/gf/util/gpage"
)

// wrapContent wraps each of the page tag with html li and ul.
func wrapContent(page *gpage.Page) string {
	content := page.GetContent(4)
	content = gstr.ReplaceByMap(content, map[string]string{
		"<span":  "<li><span",
		"/span>": "/span></li>",
		"<a":     "<li><a",
		"/a>":    "/a></li>",
	})
	return "<ul>" + content + "</ul>"
}

func main() {
	s := g.Server()
	s.BindHandler("/page/custom1/*page", func(r *ghttp.Request) {
		page := r.GetPage(100, 10)
		content := wrapContent(page)
		buffer, _ := gview.ParseContent(`
        <html>
            <head>
                <style>
                    a,span {padding:8px; font-size:16px;}
                    div{margin:5px 5px 20px 5px}
                </style>
            </head>
            <body>
                <div>{{.page}}</div>
            </body>
        </html>
        `, g.Map{
			"page": content,
		})
		r.Response.Write(buffer)
	})
	s.SetPort(10000)
	s.Run()
}

执行后,页面输出结果为:

定义分页标签名称

package main

import (
	"github.com/gogf/gf/frame/g"
	"github.com/gogf/gf/net/ghttp"
	"github.com/gogf/gf/os/gview"
	"github.com/gogf/gf/util/gpage"
)

// pageContent customizes the page tag name.
func pageContent(page *gpage.Page) string {
	page.NextPageTag = "NextPage"
	page.PrevPageTag = "PrevPage"
	page.FirstPageTag = "HomePage"
	page.LastPageTag = "LastPage"
	pageStr := page.FirstPage()
	pageStr += page.PrevPage()
	pageStr += page.PageBar()
	pageStr += page.NextPage()
	pageStr += page.LastPage()
	return pageStr
}

func main() {
	s := g.Server()
	s.BindHandler("/page/custom2/*page", func(r *ghttp.Request) {
		page := r.GetPage(100, 10)
		buffer, _ := gview.ParseContent(`
        <html>
            <head>
                <style>
                    a,span {padding:8px; font-size:16px;}
                    div{margin:5px 5px 20px 5px}
                </style>
            </head>
            <body>
                <div>{{.page}}</div>
            </body>
        </html>
        `, g.Map{
			"page": pageContent(page),
		})
		r.Response.Write(buffer)
	})
	s.SetPort(10000)
	s.Run()
}
