Question

我正在尝试使用Meteor.js创建一个多路径Web应用程序。我添加了iron：router包，我在＆＃34; lib＆＃34;中创建了以下router.js文件。文件夹（在根目录下）。它看起来像这样：

//////////////////////////
// Router
//////////////////////////

Router = {
    uri: _.compact(window.location.pathname.split("/")),
    routes: [],

    addRoute: function(route, template) {
        var segments =  _.compact(route.split("/"));

        var placeholders = _.reduce(segments, function(currentArr, piece, index) {
            if (piece.substr(0, 1) === ":") {
                currentArr.push(index);
                segments[index] = piece.substr(1);
            }
            return currentArr;
        }, []);

        this.routes.push({
            route: segments,
            template: template,
            placeholderIndexes: placeholders
        });
    },
    getMatchingRoute: function(){
         for (var i in this.routes) {
             var route = this.routes[i];
             var data = {};

             if (route.segments.length === this.uri.length) {
                 var match = _.every(route.segments, function(seg, i){
                      if (_.contains(route.placeholderIndexes, i)) {
                           data[seg] = this.uri[i];
                           return true;
                      } else {
                           return seg === this.uri[i];
                      }
                 }, this);

                 if (match) {
                      return {
                          data: data,
                          template: route.template
                      }
                 }
            }
        }
        //no matches (add 404 or default template maybe?)
        return false;
    },
    run: function(){
        var route = this.getMatchingRoute();
        if (route) {
            var fragment = Meteor.render(function() {
                if (Template[route.template] !== undefined) {
                     return Template[route.template](route.data);
                }
            });

            document.body.appendChild(fragment);
        } else {
            //404
        }
    }
};

在本地流星服务器上运行时，我得到以下输出：

=> Started proxy.                             
=> Started MongoDB.

发生了什么事？为什么不识别窗口变量。

Answer 1

lib个文件夹中的项目在服务器和客户端上运行。由于服务器上不存在window，因此会抛出错误。

Meteor.js：ReferenceError：未定义窗口
