III. The extend method of jquery also has an overload prototype:
Extend (Boolean, DEST, src1, src2, src3 ...)
The first parameter 'boolean' indicates whether to perform a deep copy. The other parameters are the same as described above. What is "Deep copy"? Let's look at an example:

This article is the 7th article in the "correct open mode of WeX5" series, which details the additions and deletions of data components in WeX5 and the method of data locating.PrefaceA preliminary study on data components we briefly introduce the introduction of data components and the underlying structure and features, and implement simple data presentation and data churn. As mentioned in the previous article, the data component is a mapping of the background database table in the front end, an

Sometimes these tables can also be used to store metadata, such as the desired data type. This is necessary because the database only allows one col
