JQuery1.9API video full presentation

Currently, jQuery, as an excellent javascript framework, has been released to version 1.9 (which provides 295 methods). Its excellent design concepts and Perfect compatibility completely conquer this era. Because of its efficient version update, our learning speed often cannot keep up with its update speed. As a user, how to quickly master it has become a wish of most people. Although it has a sound API, its English level is too low and it can only be discouraged. Some good people who are selfless and dedicated in China have translated the translation, but for the lazy and busy programmers, the shortage of personal time has no time to read the system. In view of the current situation in China, I am not dedicated to recording a complete video of jQuery API for everyone to learn. This video fully complies with the original flavor of the official API, and the teaching plan fully follows its API. A video is parsed for each method, so that each video is short and precise, making it easy for viewers to find and watch it accurately. This avoids the disadvantages of overlong videos that are preferred by existing training institutions in China and is difficult to find a specific knowledge. I will give my own opinions on each API and pay attention to the usage details of each method. If you think a video recording is poor or incorrect, you can directly send an email to me or contact me via QQ (40780734. If you think that there is no value for your old man, you can directly drift over it, because everyone understands the truth of "difficult tone of Speech. I have always believed that, without a long journey, there are thousands of miles; without a small stream, there is no river. We hope to build a platform for learning with you here.
