: However, sometimes the Json data is spliced by itself, and is directly read using js, and it is found that the read data is undefined... that is to say, like Var s = "{name1: 'name1', name2: 'name2'}"; js treats it as a string rather than JSON data. Therefore, we need to convert it into JSON data. Note: If you writ

XML and JSON are two commonly used formats for data description and transmission today, especially when it comes to JS using JSON quite frequently. Naturally, in the Java world, it is the XStream and json-lib that are the components that JavaBean and the two formats convert

Define a class: {code...}. The JSON format I want to generate is similar to: {code...}. The UserBean contains an uncertain number of objects... How to generate such JSON data ...? Is there anything like List #039; amp; lt; #039; T #039; amp; gt; #039; in JAVA .... Define a class: class UserBean { public $user_id = 0; public $user_name = 'null';

We must have encountered similar problems during the development process. If we directly pass the array obtained by js to the backend, the backend cannot differentiate the array, because if the js array is two-dimensional, it is like this: 1, zhang San, Li Si, 26 So here we will sort out the solution.

JSON (JavaScript Object Notation) is a lightweight data exchange format. Easy to read and write. It is also easy to parse and generate machines. It is based on a subset of JavaScript Programming Language, Standard ECMA-262 3rd Edition-December 1999. JSON uses a completely language-independent text format, but it also uses a habit similar to the C language family, including C, C ++, C #,
