How to Select jQuery version 1.x? 2. x? 3. x ?, Jquery1.x

Preface

When you select a version, the general principle is that the newer the better, but in fact, the jQuery version is constantly improving and developing, and the latest version is the highest technology level at that time, it is also the most advanced technology concept. It is worth thinking about how to select the jQuery version. Let's take a look at the details below.

Currently, jQuery has three major versions:

1. x: compatible with ie678, which is the most widely used. It only performs BUG maintenance and does not add any new features. Therefore, for general projects, you can use version 1.12.4 (December 4, May 20, 2016)

2. x: This product is not compatible with ie678 and is rarely used. It is only officially used for BUG maintenance and features are not added. If you do not consider compatibility with earlier versions of browsers, you can use 2.x. Final Version: 2.2.4 (January 1, May 20, 2016)

3. x: not compatible with ie678. Only the latest browser is supported. Unless otherwise specified, version 3.x is generally not used. Many old jQuery plug-ins do not support this version. Currently, this version is officially updated and maintained.

In 1.x versions, there are many subdivided versions, and the functions of each version may vary. Most of the tutorials on the Internet are in 1.x.

Maintaining ie678 is a headache. In general, we will load an additional css and js for separate processing. Fortunately, the number of users who use these browsers is gradually decreasing, and computer users have been gradually replaced by mobile users. If there are no special requirements, they generally choose to give up support for ie678.

Status quo

For the moment, the market share occupied by Internet Explorer in China is still relatively large, and it is unrealistic to directly exceed 2. x. The following is a piece of data from the Net Market Share. It can be seen that although the use of IE browser has declined, it still occupies half of the proportion. In view of the various versions of IE browser, IE 8.0 shares a relatively large market compared with other versions.

Who is jQuery 2.x suitable?

Since jQuery 2.x does not support old browsers, why should we develop this version?

It should be noted that this version is mainly used in some advanced JS environments, that is, browsers with newer versions. These JavaScript codes have little to do with old IE, while most of jQuery 1.x code is compatible with old browsers, which increases the running burden and affects the running efficiency.
