JavaScript DOM Programming Art-Learning Notes

Find the foundation is not very good, tutorial a bit. 37 bought 2 books (DOM programming and advanced programming).

In the past, reading is always self-drawing, a little boring. Now write it down, and maybe it will be a classic. Ha ha........... It's all nonsense.

First day (December 2016 11):

1.js was developed by Netscape and Sun Corporation.

ecmascript-Standardization of JS

JS was first called LiveScript.

2.Dom is a set of standards that everyone agreed to commonly known. For example, you call a car that has 4 wheels and can run.

Dom is an API. In the field of software development, API is the front-end and background agreed a set of standards, the front-end send what kind of field, back to the corresponding field. The purpose of the API is to facilitate communication and cooperation.

The concept of 3.dhtml was put forward 20 years ago, is now the front-end development advocated, HTML focus on the markup, CSS specifically to do the style, JS dedicated to do the interaction. It can be seen that the underlying things are very long-term and vary little. Now the popular VR technology, its programming basis is well-known C # (this read as CSharp, do not read C well) and other basic technology.

4.ie killed Netscape, because every Windows system is loaded with IE. So, it's important to stand on the team. However, Lookers, onlooker sees most, really to queued that time, will not be clear. But I heard that the security coefficient of IE is very high, this .... The only experience is that, with IE landing ABC's official website, let me restart several times the browser ....

5. Apple launched its own Safari browser in 2003. That year, I was in Grade 2.

6.①webkit:safari browser and Chrome browser kernel

②gecko Firefox browser's kernel

③trident IE's kernel

7. The blind: Why the introduction of CSS with HREF. And the introduction of JS with Src it,

Give a chestnut: ①html is like a person.

②css is like clothes, clothes can be one piece set (overlay css-href overlay attached resources)

③js is equivalent to a person's behavior. One behavior is replaced by another behavior. (src-) For example: the habit of drinking milk tea will replace the habit of drinking coffee.

Off-topic: Don't tell me anything, milk tea and coffee can be a drink ..... According to the absolute nature of philosophy, a point in time, only one thing can happen. It's either drinking milk tea or drinking coffee. Even if they're stacked, there's a proportional relationship.
