Detailed explanation of complete examples of component development using jQuery

黄舟Original: 2017-03-18 15:01:331417browse

The principles of using jQuery for component development and using pure JavaScript scripts (without using a framework) are basically similar, especially the organization of public methods is the same.

The difference is that jQuery uses a plug-in mechanism to directly bind the operation object (DOM element) through $(), and then bind events to the DOM element or HTML code.

Another difference is that jQuery is used as a tool to create DOM objects, quickly find specified DOM objects, etc.

The example test passed.

Basic simple example only implements the functions of adding pages and selecting pages.
