Hi，Edited . As you can see in the Actual result the "script" codes were missed.
HTML natively supports <script> elements.
You shouldn't use {{}} this way; {{}} is used as a key to match replacement text.
follow the steps below to delete, you can achieve your desired effect:
- {{/*
<script>
var x;
var txt="";
var person={{.JsonParam}}
for (x in person){
txt=txt + person[x].a;
}
document.getElementById("demo").innerHTML=txt;
</script>
- */}}There is problem with your javascript usage. You need to use a struct to specify an object when using a template.
pls check your javascript code.
Code that can be used for reference:
directory structure:
.
├── main.go
└── templates
└── test.tmplpackage main
import (
"net/http"
"github.com/gin-gonic/gin"
)
type JsonParam struct {
X int64 `json:"x"`
Y int64 `json:"y"`
}
func main() {
router := gin.Default()
router.LoadHTMLGlob("templates/*")
router.GET("/test", func(c *gin.Context) {
c.HTML(http.StatusOK, "test.tmpl", gin.H{
"title": "test",
"MyParam":"MyParam",
"JsonParam": []JsonParam{{X: 1,Y: 2},{X: 3,Y: 4}},
})
})
router.Run(":8080")
}{{define "test.tmpl"}}
