Comments: The content of this lesson is to introduce web storage and use it to store key-value pair data in a browser. The function is the same as the previous cookie, but it is better, if you are more interested in the stored data, you can learn about it. In this lesson, we will introduce web storage and use it to store key-value pairs in your browser, the function is the same as the previous cookie, but it is better to store more data. There are two

two different projects, one of which is to Use Javabean for transmission media, another method is used. In the end, this JavaBean becomes our nightmare. To make a general solution, we will reconstruct it using JavaBean as the transmission media project, increased the workload. 5. the idea of MVC layering is actually to let professional people do professional things, be good at page-based, and be good at logic-based logic. Project development based on MVC idea is usually horizontally grouped,

What is pair? The introduction of pair classes is introduced in C ++ standard library as follows: The classPairIs providedTreat two values as a single unit. It is used in several places within the C ++ standard library. In particle,The container classesMapAndMultimapUsePairS to manage their elements, Which are key/value pairs (see section 6.6).

Loops: There are two python loops, for and whileThe For loop indicates that an item variable is within the collection, and then continues the loop until the variable is not within a few, and then jumps out of the loop.such as a set a=[1,2,3,4];For I in A:do sth;A while loop is a conditional loop that executes a loop when the condition is met. Otherwise, it will not be executed.Like whata=[1,2,3,4]i=0;While Ido sth;i++; #必须控制变量.Key-value pairs:Key-value pairs
