通过javascript检查连接 [英] check connection via javascript

问题描述

我不会使用javascript

i wont to check connection available using javascript

推荐答案

检查连接是否可用，就像您在谈论Internet连接一样.如果是这样:

您可以通过发出失败的XHR请求来确定连接丢失.
标准方法是重试几次请求.如果未通过，请警告用户检查连接，然后正常失败.
对于XMLHttpRequest，请阅读此处: XMLHttpRequest对象 [

Looks like you are talking of Internet Connection. If so:

You can determine that the connection is lost by making failed XHR requests.
The standard approach is to retry the request a few times. If it doesn''t go through, alert the user to check the connection, and fail gracefully.
For XMLHttpRequest, read here:XMLHttpRequest Object[^]
