1. Understanding jquery
DOM object: The Document Object model
jquery object: An object that is produced after wrapping a DOM object through jquery. This is unique to jquery objects, where you cannot use any of the DOM object's methods in a JQuery object, and the DOM object cannot use the jquery object. (This is the one I often mix when I write code)
The interchange of Dom objects and jquery
JavaScript as an object-oriented language, understanding of objects, prototypes, closures, module patterns and other technical points for becoming a qualified JavaScript programmer is very important, for many years did not write a blog, today to throw a jade, under the basic do not do the front end, but quite interested, Willing to study with you. This article is only the more important points of knowledge that I think, the coherence is not particular
By default, objects in JavaScript are mutable. We can change the original values (strings, numbers, etc.) and objects. Let's take a look at this object:Let obj = { ten, obj: { "mutable object" }}You can easily change it by:5"changed! " / / {// num:5,// obj: {// content: "changed!" // }// }It's very clear, isn't it? So, what can we do to make the object immutable?1, l
In the first part of this four-part series, we'll figure out what data binding is, and what the advantages are, and how to start using it, compared to other methods of processing XML data in a Java application. This section examines why data binding is used and how constraints are modeled to allow XML documents to be converted into Java objects. It also covers the inputs and outputs used to generate data-binding classes.
Do you want to use XML in you
jquery objects converted to DOM objectsOnly jquery objects can invoke the various functions of the JQuery class library, and the properties and methods of some DOM objects cannot be invoked on jquery, but basically the functions provided by the JQuery class library contain all the DOM operations.The index of the jquery object holds the DOM object, so you can conv

The DOM object and the jquery object are always confused at first. Now make a summary of this:DOM object: Document Object model. Each DOM can be seen as a tree. Like Ul,li ol DL P H1 and so on are DOM element nodes. These element nodes can be obtained through JS's getElementsByTagName and getElementById. Dom elements like this are DOM objects.DOM objects can use the methods in JavaScript. Such as:var domobj = document.getElementById ("id");var objhtml
By using standard JavaScript to manipulate the DOM against the Jquyer Operation DOM, it is not difficult to find:
The object that is wrapped by the jquery method is a class array object. It's completely different from Dom objects, and the only similarity is that they all work with the DOM.
Working with the DOM through jquery allows developers to focus more on the development of business logic without needing to know exactly which DOM node

The running result is as follows:
Analysis: in a class, if other class members exist, they are constructed first. If the class object is static, the static object is constructed before all other objects, if this static object inherits A parent class, it should first construct the parent cl
