JavaScript at a glance--"javascript"

For the north wind Nets Li Tinghui teacher's JavaScript video is really drunk. The overall structure of the video is clear and the content is relatively simple. JS is a flexible, open language, grammatical rules are not so rigid, it is easy to accept.

The basic part of JS, like C #, contains data types, operators, expressions, and statement structures. However, JS is more flexible, there are only 6 types of data, and the statement structure does not have a do...loop type.

Advanced basis, functions are slightly different from the previous one, using anonymous functions and closures. There is no method name function, you can also manipulate the variables within the function, is not very magical! There are three types of objects, built-in objects, local objects, and host objects, all of which are simple to use. The array is very different from the previous one, and the data type inside the array can be different, and the length can be not fixed, only a single-dimensional array. Memory problems have always been the focus, difficulties, strings have a lot of embodiment. Regular expressions are used to perform various information matching, validation, and writing on the client, relieving the pressure on the server.

JS in addition to core programming, the other two is the DOM and bom.dom related to the operation of the node in the document, the BOM is mainly browser model, the property method inside, are related to the operation of the Web page.

Object-oriented, inheritance, encapsulation, polymorphism are present. Prototypes are mechanisms of inheritance. JS can also implement the corresponding interface.

If the sentence structure is flesh, the data is blood. Cookies are primarily responsible for local access to data, XML and JSON one can pass on lightweight data, one can serialize data, and Ajax has a unique killer for asynchronous refreshes of forms.

Study for about 1.5 months of time, master steaming recently to the plan also urged strict, especially thanks to her serious and responsible. There is always one of the most important things to do in each stage, adhere to the 28 law, continue to work!
