英文:
GO: javascript and html MIME error
问题
我正在尝试在我的GO应用程序中加载JavaScript，但是我遇到了错误：
Resource interpreted as Script but transferred with MIME type text/html: "http://localhost:4747/twttr.js". localhost/:6Uncaught SyntaxError: Unexpected token <
GO代码：
package mainimport ("net/http""html/template")func main() {http.HandleFunc("/", handler)http.ListenAndServe(":4747", nil)}func handler(w http.ResponseWriter, r *http.Request) {if r.URL.Path == "/twttr.js" {http.ServeFile(w, r, "twttr.js")return}t, _ := template.ParseFiles("home.html", "edit.html")t.Execute(w, map[string]string{"Title": "My title", "Body": "Hi this is my body"})}
在我的HTML中，我有类似以下的内容：
<!DOCTYPE html><html><head><title>twitter!</title><script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script><script type="text/javascript" src="twttr.js"></script><head><body><h1>Add new tweet</h1><form action="/save/{{.Title}}" method="get"><button type="button" value="addtweet" class="addtweet">Add Tweet!</button></form>Title is {{.Title}}{{template "edit.html" .}}</body></html>
JS代码：
$(document).ready(function(){$('.addtweet').click(function(){alert("Handler for .click() called.");});})
目录结构：
static/home.htmltwttr.jstwttr.go
我认为问题可能与我在GO应用程序中显示模板/HTML的方式有关。但我不知道确切的问题。我对GO和编程都很新，所以非常感谢任何指导！

JS:
$(document).ready(function(){$('.addtweet').click(function(){alert("Handler for .click() called.");});})
Directory structure:
static/home.htmltwttr.jstwttr.go
I'm thinking it's got something to do with how I display the templates / html in the GO app. But I don't know the exact problem. I'm new to GO and programming in general so any guidance is much appreciated!

如果你查看JS文件加载的结果，它是否是预期的文件？根据发布的代码，我没有看到你处理它，我猜想可能没有处理。除非你没有发布所有内容。你似乎对每个请求都提供相同的结果，包括JS文件。
要通过GO提供文件，请参考：http://golang.org/pkg/net/http/#ServeFile
你需要检查URL并相应地处理。例如：
if r.URL.Path == "/twttr.js" {http.ServeFile(w, r, "static/twttr.js")return}t, _ := template.ParseFiles("home.html", "edit.html")t.Execute(w, map[string]string{"Title": "我的标题", "Body": "嗨，这是我的正文"})
英文:
If you look at your the result of the JS file load, is it even the expected file? I don't see you handling it, based on the posted code, I would guess not. Unless you haven't posted everything. You seem to be serving the same result for every request, including the JS file.
For serving files through GO, look at: http://golang.org/pkg/net/http/#ServeFile
You need to check the URL and handle accordingly. Eg:
if r.URL.Path == "/twttr.js" {http.ServeFile(w, r, "static/twttr.js")return}t, _ := template.ParseFiles("home.html", "edit.html")t.Execute(w, map[string] string {"Title": "My title", "Body": "Hi this is my body"}
