datatables是个很不错的表格,使用GO时排序问题很麻烦,于是写了个函数
package tools import ( "github.com/astaxie/beego/context" "strconv" ) //datatables的排序 func DT_order(aColumns []string, Input *context.BeegoInput) string { maps := make(map[string]string) if iSortCol_0, _ := strconv.Atoi(Input.Query("iSortCol_0")); iSortCol_0 > -1 { ranges, _ := strconv.Atoi(Input.Query("iSortingCols")) for i := 0; i < ranges; i++ { istring := strconv.Itoa(i) if iSortcol := Input.Query("bSortable_" + Input.Query("iSortCol_"+istring)); iSortcol == "true" { sordir := Input.Query("sSortDir_" + istring) thisSortCol, _ := strconv.Atoi(Input.Query("iSortCol_" + istring)) if sordir == "asc" { maps[aColumns[thisSortCol]] = "asc" } else { maps[aColumns[thisSortCol]] = "desc" } } } } var order string if len(maps) > 0 { for k, v := range maps { if order == "" { order = k + " " + v } else { order += "," + k + " " + v } } } return order }
使用方法:
order := models.DT_order([]string{"id", "username", "password"}, this.Ctx.Input)
fmt.Println(order)
