Embodiment Construction

[0014] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0015] The technical scheme of concrete implementation of the present invention is:

[0016] Such as figure 1 As shown, a method of implementing key-value pair storage based on javascript includes the following steps:

[0017] 1) Define a Map method, which contains at least the following three basic methods:

[0018] put(key, va1ue), get(key), remove(key), other methods can be extended;

[0019] 2) Create a collection in the Map method, which contains an object with an array length of 2, so that the array object can be used to save the key and value;

[0020] 3) Implement the storage operation in the put method: first traverse the collection object crea...

Abstract

The invention discloses a mode for realizing key-value storage based on javascript. The mode comprises the following steps of: 1) defining a Map method; 2) creating a set in the Map method, wherein the set contains an object with array length of 2, so that keys and values can be conveniently stored by using array objects; 3) performing a storage operation in a put method; 4) obtaining a value object according to a key value in a get method; and 5) performing a deletion operation in a remove method. According to the mode, JavaScript is applied to the set for storing the object array, so that the keys and the Values can be stored separately, the problem that JavaScript cannot realize Key-Value storage is solved, and the cumbersome process for cyclically traversing the values after storage is simplified. More succinctly, the problem in local temporary caching of information or information cascade processing (such as quick city and region correlation) is efficiently solved.

Description

technical field [0001] The invention relates to a method for realizing key-value pair storage based on javascript. Background technique [0002] javaScript is an object-based and event-driven and relatively secure client-side scripting language. It is a dynamic-type, weak-type, and prototype-based literal scripting language; it is also a script widely used in client-side Web development. Language; often used to add dynamic functions to HTML (a subset of Standard General Markup Language) web pages, such as responding to various operations of users. Due to the particularity of its language, it is impossible to directly store objects in the form of Key-Value (key-value pairs), so that after storing data, it is impossible to directly add a certain identifier and quickly obtain the corresponding value. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art, and provide a method for realizing key-value pair storage ba...
