I. Basic knowledge about JSON.

JSON strings are parsed into JSON data formats in JS. There are two methods:1. Use the eval () function.2. Use the Function object for return parsing.Method 1: Use the eval function to parse and use the jQuery each method to traverseThe JSON data parsing method using jQuery is used as the transmission object of jQuery asynchronous requests. The result returned by
JSON has become a recognized standard for data transfer between the current server and the Web application, but just as many of the things we are accustomed to, you will feel that it is taken for granted that you do not think deeply. We rarely think about how these JSON libraries are different, but in fact they are really not the same. Therefore, we ran a benchmark to test several commonly used
