如何将名称变量从路由器传递到 FriendInfocollection？每当我浏览到 localhost/app/person/MyName 时，console.log 都会为 localhost/slim/index.php/person/ 返回 404

有人可以指出我与集合共享此变量的正确方向，以便它使用正确的网址吗？

您应该像这样定义路由器：

var AppRouter = Backbone.Router.extend({
    routes: {
        'name/:name'                : 'getPerson'
    },
getPerson: function(name) {
    var callperson = new Person.Details({
        name        :   name
    });
}

dom 准备好时实例化路由

    app_router = new AppRouter;

现在您可以在视图中访问这样的名称：

    this.options.name

但是您必须在初始化函数中定义选项变量

    initialize: function ( options )

当然，您可以像这样设置模型：

    model.set('name', name)
