Localstorage.setitem (att) automatically stores att as a string, such as:
The code is as follows
Copy Code
var arr=[1,2,3];Localstorage.setitem ("temp", arr);typeof Localstorage.getitem ("temp"); Returns a stringLocalstorage.getitem ("temp"); returns 1,2,3
It is worth noting, however, that Localstorage.setitem () does not automatically turn the JSON object into a string, such as:
The code is as follo

Object-oriented method is more and more important in the analysis, design and coding of software development, and it has some advantages that can not be compared with other development methods in adapting to the change of system requirements, improving the reusability of software and developing efficiency. Object-oriented idea describes the concepts in the application domain as ob

With the evolution of high-performance computing from traditional host to networked cluster, the traditional host-based storage architecture has gradually developed to networked storage, and the trend of computing and storage separation is becoming more and more obvious. A new file system for Linux clusters has been launched internationally for the lack of SAN an

Swift is an object storage service for OpenStack. In the Php-opencloud library, the ObjectStore class (OpenStack or Rackspace) created by the Connection object is accessed. For example: $cloud = new \opencloud\openstack (Array (' username ' = ' = ' {username} ', ' password ' = ' {password} ')); $swift = $ Cloud->objectstore (' CloudFiles ', ' DFW '); with the new

Recently, a student asked me about the difference between the hadoop Distributed File System and openstack Object Storage Service, and said a few words to him. I personally think that data processing and storage are preferred. There is no absolute quality. It should be used based on specific applications.
