Hi. I remain mystified. I tried your suggestion, but it didn't work.
This is .../learn/main.go
func main() {
http.HandleFunc("/", handleRoot)
http.Handle("/css/", http.FileServer(http.Dir("webpages/css")))
http.Handle("/js/", http.FileServer(http.Dir("webpages/js")))
fmt.Println("listening on port 8877")
http.ListenAndServe(":8877", nil)
}
The files aren't found -- as soon as http://127.0.0.1:8877/ is loaded the
two error messages produced are:
Refused to apply style from 'http://127.0.0.1:8877/css/main.css' because
its MIME type ('text/plain') is not a supported stylesheet MIME type, and
strict MIME checking is enabled.
127.0.0.1/:6 GET http://127.0.0.1:8877/js/file.js net::ERR_ABORTED 404 (Not
Found)
But simply displaying .../learn/webpages/main.html via chrome works
just fine.
For the record, .../learn/webpages/main.html:
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="css/main.css">
<script type="text/javascript" src="js/file.js" ></script>
</head>
<body>
<div>
<h2> file location exercise </h2>
<input type="button" onclick="f1()" value="Find File" />
</div>
</body>
</html>
.../learn/webpages/css/main.css:
body {
background-color: Azure;
color: blue
}
and .../learn/webpages/js/file.js:
function f1() {
alert("Hello from .../learn/webpages/js/file.js")
}
So, I'm still in need of help.
Thanks!
