Сер*_*сов 0 html templates loops go
我想在 go 包“模板”中用 HTML 制作表格，我想在循环中添加行，但我没有找到如何做到这一点
我的代码：
package main
import (
"net/http"
"html/template"
)
type Devicevalue_view struct {
Devicetype string
Iddevice string
Devicename string
Oidname string
Value string
}
func page_1(w http.ResponseWriter, r *http.Request){
for i:=1; i<10; i++{
data := Devicevalue_view{
Devicetype: "devicetype",
Iddevice: "iddevice",
Devicename: "devicename",
Oidname: "oidname",
Value: "value",
}
tmpl, _ := template.ParseFiles("./index.html")
tmpl.Execute(w, data)
}
}
func main() {
http.HandleFunc("/table", page_1)
http.ListenAndServe(":3000", nil)
}
我得到这个：
Devices
Type Name Param Time Value
devicetype iddevice devicename oidname value
Devices
Type Name Param Time Value
devicetype iddevice devicename oidname value
...
但我想要这样的东西
Devices
Type Name Param Time Value
devicetype iddevice devicename oidname value
devicetype iddevice devicename oidname value
...
我不明白如何连接一张表中的所有单元格

因为你在里面执行模板for loop。您也可以通过单个struct. 要传递数组，您必须将其作为结构的成员传递。
package main
import (
"html/template"
"net/http"
)
type Data struct {
Items []Devicevalue_view
}
type Devicevalue_view struct {
Devicetype string
Iddevice string
Devicename string
Oidname string
Value string
}
func page_1(w http.ResponseWriter, r *http.Request) {
data := Data{}
for i := 1; i < 10; i++ {
view := Devicevalue_view{
Devicetype: "devicetype",
Iddevice: "iddevice",
Devicename: "devicename",
Oidname: "oidname",
Value: "value",
}
data.Items = append(data.Items, view)
}
tmpl, _ := template.ParseFiles("./index.html")
tmpl.Execute(w, data)
}
func main() {
http.HandleFunc("/table", page_1)
http.ListenAndServe(":3000", nil)
}
此外，您必须遍历数据并动态生成行。

{{ end}}
</table>
