Web site access Statistics code implemented by JavaScript

JavaScript implements the website access statistics code:
Web sites generally have access statistics tools, more efficient and practical tools are various, and very accurate. Practical JavaScript can also be a simple implementation of this function, although not commonly used on the network of precision, but it does also achieve a certain function, the following is a code example, interested friends can refer to:
