英文:
Uncaught SyntaxError: Unexpected token <
问题
我正在使用go运行一个服务器。当我访问localhost:8888/static/ajax.html时，没有出现错误。但是当我只访问localhost:8888时，出现了以下错误：
> "Uncaught SyntaxError: Unexpected
> token <"
默认情况下，"/"会提供ajax.html文件，但是这样做我没有得到预期的结果。另一方面，调用/static/ajax.html时，我得到了预期的结果，没有任何错误。
server.go包含以下内容：
package mainimport ("http""flag")//var path = flag.String("storage", "/home/chinmay/work/jstree/", "Set storage directory, use absolute path")var root = flag.String("root", "/home/chinmay/work/ajax/", "Set root directory, use absolute path")func temp(w http.ResponseWriter, r *http.Request){http.ServeFile(w,r,*root +"ajax.html")}func main(){http.HandleFunc("/", temp)http.Handle("/static/", http.FileServer(*root, "/static/"))http.ListenAndServe(":8888", nil)}
ajax.html包含以下内容：
<html><head><script type="text/javascript" src="/static/jquery.js"></script><script type="text/javascript" src="/static/three/Three.js"></script><script type="text/javascript" src="/static/js/Detector.js"></script><script type="text/javascript" src="/static/js/RequestAnimationFrame.js"></script><script type="text/javascript" src="/static/js/Stats.js"></script><script type="text/javascript">$.ajaxSetup ({cache:false;})$("#container").ready(function(){$("button").click(function(){$.getScript("model.js");});});</script></head><body><button>Use Ajax to get and then run a JavaScript</button><div id="container"></div></body></html>

英文:
I am running a server on go. When I access the localhost:8888/static/ajax.html,
I get no errors. But when I just access localhost:8888 I get
an error saying:
> "Uncaught SyntaxError: Unexpected
> token <"
By default "/" serves ajax.html file, but doing so I don't get the
expected result. On the other hand on calling /static/ajax.html I am
getting the expected result without any errors.
server.go contains the following :
package mainimport ("http""flag")//var path = flag.String("storage", "/home/chinmay/work/jstree/", "Set storage directory, use absolute path")var root = flag.String("root", "/home/chinmay/work/ajax/", "Set root directory, use absolute path")func temp(w http.ResponseWriter, r *http.Request){http.ServeFile(w,r,*root +"ajax.html")}func main(){http.HandleFunc("/", temp)http.Handle("/static/", http.FileServer(*root, "/static/"))http.ListenAndServe(":8888", nil)}
ajax.html contains the following:
<html><head><script type="text/javascript" src="/static/jquery.js"></script><script type="text/javascript" src="/static/three/Three.js"></script><script type="text/javascript" src="/static/js/Detector.js"></script><script type="text/javascript" src="/static/js/RequestAnimationFrame.js"></script><script type="text/javascript" src="/static/js/Stats.js"></script><script type="text/javascript">$.ajaxSetup ({cache:false;})$("#container").ready(function(){$("button").click(function(){$.getScript("model.js");});});</script></head><body><button>Use Ajax to get and then run a JavaScript</button><div id="container"></div></body></html>

我没有解码问题，但可能的问题是你调用脚本的方式
$.getScript("model.js")
http://localhost:8888/ 会调用 http://localhost:8888/model.js
http://localhost:8888/static/ajax.html 会调用 http://localhost:8888/static/model.js
编辑
另外，你的 model.js 在第133行有一个错误
for( j = 0, jl = meshes.length; j < jl; j++ )
正确的 for 循环格式是
for (变量=起始值; 变量<=结束值; 变量=变量+增量)
j < jl; 是多余的，导致出现 "Unexpected token <" 错误消息
英文:
I did not decode the question, but a possible issue is the way you call your script
$.getScript("model.js")
http://localhost:8888/ will call http://localhost:8888/model.js
http://localhost:8888/static/ajax.html will call http://localhost:8888/static/model.js
EDIT
also your model.js has an error on line 133
for( j = 0, jl = meshes.length; j < jl; j++ )
the proper for loop format is
for (variable=startvalue;variable<=endvalue;variable=variable+increment)
j < jl; is extra, resulting in the "Unexpected token <" error message
