需要通过按钮单击将golang数据发送到html
package main
import (
"time"
"fmt"
"encoding/json"
"net/http"
)
type GetTime struct{
Current_time string `json:"date"`
}
func main(){
t:=(time.Now().Format(time.RFC3339))
ctime:=GetTime{Current_time:t}
byteArray,err:=json.Marshal(ctime)
{
if err!=nil{
fmt.Println(err)
}
}
fmt.Println(string(byteArray))
}
我需要将上面提到的Go lang数据发送到Html表单，当按钮在Html页面中被点击时

你可能很少花精力来解决这个问题。虽然我很无聊，所以我决定帮助你。这是您的后端：package mainimport ( "encoding/json" "fmt" "log" "net/http" "time")type Response struct { CurrentTime string}func main() { http.Handle("/", http.FileServer(http.Dir("web"))) http.HandleFunc("/get-time", func(rw http.ResponseWriter, r *http.Request) { ctime := Response{ CurrentTime: time.Now().Format(time.RFC3339), } byteArray, err := json.Marshal(ctime) if err != nil { fmt.Println(err) } rw.Write(byteArray) }) if err := http.ListenAndServe(":5000", nil); err != nil { log.Fatal(err) }}您还需要位于 （web/index.html） 中的前端：<!DOCTYPE html><html><head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title></head><body> <button id="gt">get time</button> <div id="res"></div> <script> document.getElementById("gt").onclick = async (e) => { var req = await fetch("\get-time").then(r => r.json()) document.getElementById("res").innerHTML = req.CurrentTime } </script></body></html>
