DBUtils source code analysis, dbutils source code In fact, in this article, I only analyzed the operation process of dbutis query. As for why the class should be designed in this way, the design patterns and other advanced knowledge points should be discussed in the next section. First, let's take a look at how the simplest DBUtils works.There is a table in the d

The operations on events are nothing more than addEvent, fireEvent, and removeEvent. Generally, lib extends the functions provided by the browser to solve problems such as compatibility Memory leakage. The third problem is how to get the domReady status.6.1 event packages Browser event compatibility is a headache. The IE event is in the global window, while the mozilla event is passed in to the callback function as the event Source parameter. There are also many event handling methods. Jquery pr

Internal Storage Principle This principle is very simple. The data originally to be added to the DOM element is now centrally stored in the cache set. They are linked by a number key starti

Intermediary mode analysis, structure diagram and basic code, mediation structure diagram codeZookeeper Definition: a mediation object is used to encapsulate a series of object interactions. The intermediary makes the objects do not need to be explicitly referenced to each other, so that the coupling is loose and the interaction between them can be changed independently.Applicability: The intermediary mode
