使用Javascript从客户端使用MongoDB [英] Using MongoDB from client with Javascript

问题描述

我正在尝试仅将MongoDB与客户端的javascript一起使用，但是MongoDB的有关如何实现此目的的文档非常令人困惑.

I am trying to use MongoDB with just javascript from client, but MongoDB's documentation on how to achieve this is very confusing.

在此网页上，没有可供下载的内容，我期望看到一些内容像mongo.js.

On this webpage there is nothing to download, I was expecting to see something like mongo.js.

这里我确实找到了mongo. js，并使用此使它工作，但没有运气.

Here I did find mongo.js, and using this I am trying to make it work but with no luck.

Google Chrome浏览器中的Javascript控制台说:

The Javascript console in Google Chrome is saying:

未捕获的TypeError:对象[object Object]没有方法'init'

Uncaught TypeError: Object [object Object] has no method 'init'

在mongo.js的这段代码中:

In this snippet from mongo.js:

if ( typeof Mongo == "undefined" ){
  Mongo = function( host ){
    this.init( host );  
  }
}

有人对使用纯Javascript使用MongoDB有任何提示吗?

Does anyone have any tips on using MongoDB with pure Javascript?

推荐答案

您链接到的文档是关于使用服务器支持的Javascript使用node.js框架访问MongoDB.

The documentation you linked to is about accessing MongoDB with server-sided Javascript using the node.js framework.

MongoDB确实提供了REST Web服务，允许通过XmlHttpRequests进行基本查询.要启用它，您必须使用--rest参数启动mongod.然后，您可以像这样查询它:

MongoDB does offer a REST webservice allowing rudimentary queries through XmlHttpRequests. To enable it, you have to start mongod with the --rest parameter. You can then query it like this:

http://127.0.0.1:28017/yourDatabase/yourCollection/?filter_name=Bob

您可以像使用任何Web服务一样，使用AJAX XmlHttpRequest查询此URL.它将访问本地主机上的数据库，并返回等效于如下查询的JSON:

You can query this URL with an AJAX XmlHttpRequest like any webservice. It will access a database on localhost and return JSON equivalent to a query like this:

yourDatabase.yourCollection.find({name:"Bob"});

但是，此界面非常基本.它仅提供简单的查找查询.但是，有第三方中间件层可以提供更多高级功能.此处记录了此功能和第三方解决方案的列表:

This interface, however, is very rudimentary. It only offers simple find queries. But there are 3rd party middleware layers which expose more advanced functionality. This feature and a list of 3rd party solutions is documented here:
