Can't find js files using nginx, return 404, Why?

I deployed answer at 8090 port
when using nginx, but it can't find the js files

here is my nginx conf file:

  listen       80;
        server_name  quanting.top;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
           #limit_req zone=ip_limit;
           #root   /home/ecs-user/www;
           #index  index.html index.htm;
           limit_req zone=ip_limit;
           proxy_pass  http://172.28.142.26:8090;
           proxy_set_header Host $proxy_host;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }


        location /view/api/ {
           limit_req zone=ip_limit;
           proxy_pass  http://172.28.142.26:8888;
           proxy_set_header Host $proxy_host;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}

How can I solve the problem? thx
