科尔多瓦 - 检查WIFI连接互联网 [英] Cordova - Checking WIFI connection to internet

问题描述

我用科尔多瓦开发智能手机应用。

I use Cordova to develop a smartphone application.

在这个程序，我需要检查发送请求到服务器之前的互联网连接。

In this app, I need to check the internet connection before send request to a server.

在为了做到这一点我用科尔多瓦连接API，但在设备连接到WiFi网络，没有互联网连接的情况下，这个API说，我们有WIFI连接，

In order to do that I use the Cordova Connection API, but in the case that the device is connected to a WIFI network with no Internet connection, this API say that we have WIFI connection,

有没有什么办法来检查，如果互联网是可用的WIFI网络上？

is there any way to check if internet is available on the WIFI network ?

推荐答案

发送假Ajax请求您发送实际的请求之前，如果你和错误code为0则表示没有互联网连接。

Send an Dummy ajax request before you send the actual request, If you get and Error Code as '0' it means there is no internet connectivity.

$.ajax({
    url: 'TestUrl',
    type: 'GET',
    success: function (data) {
                // Go ahead with you request
    },
    error: function (x, y, z) {
        if (x.status == 0) {
            alert("Please connect to the internet");
        }
       else{
           alert("Other Error Occured")
        }
    }
});

其次，你还可以让你的HTML 5航海家

Secondly you can also make you of HTML 5 navigator

var condition = navigator.onLine ? "ONLINE" : "OFFLINE";
