Hello Guys,
i’m very new to this language and i have to use it for my project. I have to pass my Struct Array to my HTML-Template to Populate a drop-down. I can’t pass even a single string to populate… seems like data is empty… The Goal is to pass the whole Struct-Array. In my code i’m trying to do it with one item of them.
The drop-down gets new rows with this code but with no Data in it.
Pls help me guys…
Here is my Code of the Index.html:
<script type="text/javascript">
$(document).ready(function() {
$("#getKammer").on('click', function() {
$.ajax({
url: "http://localhost:8080/getKammer",
method: "GET",
success: function(data) {
var $dropdown = $("#Kammer");
$dropdown.append($("<option />").val(data).text(this.name));
$("#getKammer").prop('disabled', true);
},
});
});
});
</script>
And here is my Go-Code:
//Klimakammer struct
type klimakammer struct {
name string
hersteller string
ip string
sollTemp string
istTemp string
sollFcht string
istFcht string
kammerstart bool
kammerstop bool
}
//Ct01 Klimakammern erstellen
var Ct01 = klimakammer{"ct01", "weiss", "10.0.62.22", "", "", "", "", false, true}
//Kammern - Fill Klimakammer Array
var Kammern = []klimakammer{
Ct01,
}
var tmpl = template.Must(template.New("tmpl").ParseFiles("./static/Index.html"))
func main() {
http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
if err := tmpl.ExecuteTemplate(w, "Index.html", nil); err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
}
})
http.ListenAndServe(":8080", nil)
http.HandleFunc("/getKammer", func(w http.ResponseWriter, r *http.Request) {
fmt.Fprintln(w, Ct01.name)
})
}
