Front-End Learning notes--9/5~13/5 Ajax, jQuery

The weekend did not write this week's summary, and then make up today. Let's plan this week's study.

Last week's plan to do some HTML+CSS+JS demo this week, but I didn't do it. To be exact, last week basically I only Monday to Wednesday is the full force to study, Thursday night to boil a day night, from now until today did not feel back, still is so sleepy. The weekend is also for this reason, so almost no study, at home to sleep past. Sure enough, people are old and mentally keep up. Gas cry.

Let's start with a summary ....

Ajax

The relationship between JS and Ajax jquery.

1. JS is a front-end language

2. Ajax is a technology that provides an updated mechanism. jquery is a framework for the encapsulation of JS.

When using AJAX to send requests to the server, get and post, but use post in the following situations:

1. Unable to use cache file (update file or database on server)

2. Send a large number of requests to the server (post has no data limit)

3. When sending user input with unknown characters, post is more stable and more reliable than get.

The onReadyStateChange property store function is called whenever the ReadyState property is changed.

HTML5

When writing form types, such as email eg<input type= "email", in the mobile browser Safari will change the touch keyboard to match the input, the touch screen appears "@" and ".", some other types will also have a corresponding adjustment.

Jquery

A library of JavaScript lightweight

Included features: HTML element selection, HTML element manipulation, CSS manipulation, HTML event functions, JavaScript effects and animations, HTML DOM traversal and modification, Ajax

Learn some basic operations on this part of jquery on the Novice tutorial site, but later on IMOOC see that there are actually many other operations on jquery, very powerful, and intend to continue to spend time on jquery to learn this week.

Summary:

In Thursday, I received an interview notice, and then in the front-end of the written test found that although they basically mastered the use of JavaScript, but in the actual programming there are a lot of shortcomings, I can hardly write down a complete program. Without even thinking. In this respect, we must make haste to improve, otherwise there will be no more language to use.

At this point, I have to spend a little more time to think about how to improve themselves.

Plan:

This week's plan is to continue the study of jquery. and also to complete the learning and improvement of JavaScript.

jquery Learning: Complete the jquery course you are learning on IMOOC.

JavaScript: Follow IMOOC on the video to do a demo, can be combined with H5.
