(5) abstract classes cannot be directly created. You can define referenced variables.
** The abstract class does not have a method body, but ends with a semicolon.

When creating a subclass, select Browse and select the parent class name.
When creating a subclass, select abstract to generate an abstract class.

JSON (Javescript Object Notation) is a simple data format that is lighter than XML. JSON is a native JavaScript format, which means that working with JSON data in JavaScript does not require any special APIs or toolkits.The rules of JSON are simple: an object is an unordered collection of "name/value pairs". An object starts with "{" (opening parenthesis) and "}" (the closing parenthesis) ends. Each "name" followed by a ":" (colon); "' Name/value ' pair", "(comma) delimitedTo give a simple examp

Knockout is a JavaScript class library based on data model that can help you create rich text, respond to display and edit the user interface. At any time, if your UI needs to be updated automatically (for example, updates rely on user behavior or changes to external data sources), KO can be very easy to implement and easy to maintain.

About the concept and advantages of JSON, we have talked many times, do not understand the students can search, this article we mainly talk about how JavaScript processing parse JSON data.For a simple example:JS Codefunction Showjson () {var user ={"username": "Andy","Age": 20,"Info": {"tel": "123456", "cellphone": "98765"},"Address":[{"City": "Beijing", "postcode": "222333"},{"City": "NewYork", "Postcode": "555666"}]}alert (user.username);alert (user

A json data-type token string. Then, you can directly access the JSON object by using the eval () function in the JavaScript script. It is more convenient and flexible. Note that a pair of parentheses must be added at both ends of the returned string:
var json1 = web_TreeView_TreeDemo.GetJson().value;json1 = eval('(' + json1 + ')');
function showJSON() { var user = { "username":"andy", "age":20, "info": { "tel": "123456", "
In the development process, it is often the case that a function needs to return multiple values, this is a problem!!The solution to this problem online:1. Use map return value; The problem with this method is that you don't know how to return the value of the key, which can only be viewed through doc or through source code.2. Pass in a reference and modify the referenced property value. Problem: not practical.3, through the generic structure of a python-like tuple class, or construct a javabean
