Network Information API(This is an experimental technology):
网络信息API（这是一项实验性技术）：
The Network Information API provides information about the system's connection, which is in term of general connection type (e.g., 'wifi', 'cellular', etc.). This can be used to select high definition content or low definition content based on the user's connection. The entire API consists of the addition of the domxref("NetworkInformation") interface and a single property to the Navigator interface: Navigator.connection.
网络信息 API 提供有关系统连接的信息，这是根据一般连接类型（例如，“wifi”、“蜂窝”等）。这可用于根据用户的连接选择高清内容或低清晰度内容。整个 API 包括添加的 domxref("NetworkInformation") 接口和 Navigator 接口的单个属性：Navigator.connection。
var connection = navigator.connection || navigator.mozConnection || navigator.webkitConnection;
var type = connection.type;
function updateConnectionStatus() {
alert("Connection type is change from " + type + " to " + connection.type);
}
connection.addEventListener('typechange', updateConnectionStatus);

I wrote a small utility to do this. You can try it here http://ashanbh.github.io/detectClientSpeed/example2.htmland fork it on github: https://github.com/ashanbh/detectClientSpeed
我写了一个小实用程序来做到这一点。你可以在这里尝试 http://ashanbh.github.io/detectClientSpeed/example2.html并在 github 上 fork ：https://github.com/ashanbh/detectClientSpeed
Usage:
用法：
<script src="scripts/require.js"></script>
<script>
requirejs(['scripts/detectSpeed'], function (detectSpeed) {
//Callback to receive timing information
var callback = function (timings) {
console.log(timings);
}
detectSpeed.startSpeedCheck("https://s3-us-west-1.amazonaws.com/amit.shanbhag/3g/coffee-apple-iphone-laptop.jpg", callback);
});
</script>
