Jquery parsing Json format data process code_jquery

Today I learned a little bit about Json. JSON (JavaScript Object Notation) is a lightweight data exchange format. Easy for humans to read and write. It is also easy for machines to parse and generate. JSON uses a completely language-independent text format, but also uses conventions similar to the C language family (including C, C, C#, Java, JavaScript, Perl, Python, etc.). These properties make JSON an ideal data exchange language.

JSON is constructed from two structures:

A collection of name/value pairs. In different languages, it is understood as an object, a record, a struct, a dictionary, a hash table, a keyed list, or an associative array. array).
An ordered list of values. In most languages, it is understood as an array.

These are common data structures. In fact most modern computer languages ​​support them in some form. This makes it possible for a data format to be exchanged between programming languages ​​that are also based on these structures.

JSON has the following forms:

An object is an unordered collection of name/value pairs. An object starts with "{" (left bracket) and ends with "}" (right bracket). Each "name" is followed by a ":" (colon); "name/value" pairs are separated by a "," (comma).

Okay, let’s not talk nonsense and go straight to examples! ! The design of this small demo is like this. The index.jsp page accesses the server-side servlet. The servlet transfers data to index.jsp. The transferred data is in Json format. Haha... Nonsense. If the data is not in Json format, I will write this article. A blog is equivalent to deceiving the audience!

Code on the index.jsp side (easy first, then difficult order):

Copy code The code is as follows:

< ;td id="td0"> < ;/table>

lastname	firstname	address
< ;/td>
