javascript sandbox

sandbox instance, and if not (stating that the sandbox () is not called with new), use new to call the sandbox again; You can add properties to the constructor using this, or you can add attributes by prototype; Modules that need to be used can be passed through an array of module names, or they can be passed in as a module name for each parameter, and "

From a linguistic point of view, allowing code to use global variables in an uncontrolled manner is one of the most wrong choices. What is more frightening is that a variable "may" become global (at unknown time and place). But these two, along with the JavaScript language successfully came to the present. Dingzhou Technology Industry BureauIt may be limited to the size of the browser application, so it's not a disaster. Prior to this, there were two

The Sandbox mode is common in YUI3core. It is an instance object that uses the same Constructor to generate independent and independent of each other (self-contained, the namespace of the method to avoid contamination of Global Objects JavaScript itself does not provide a namespace mechanism. To avoid global space pollution caused by different functions, objects, and variable names, the common practice is

, and wildcards.4. note that in this example, we do not need to load modules from external files, but in YUI3, you can only load basic modules (usually called seed )), all other modules are loaded from external files.5. Once we know the required modules and initialize them, this means that the entry functions of each module are called.6. The callback function is finally passed into the constructor as a parameter. It uses the newly generated instance and runs it at the end.Copy codeThe Code is as

argument is the callback callback = Args.pop (), Modules can is passed as an array or as individual parameters Modules = (Args[0] typeof args[0] = = = "string")? Args:args[0], I Make sure the function is called As a constructor if (!) ( This instanceof Sandbox)) { return new Sandbox (modules, callback); } Add properties to ' this ' as needed: THIS.A = 1; this.b = 2; Now add modules to the co

Drawbacks of the namespacing patternreliance on a single global variable to be the application ' s global. In the namespacing-pattern, there is no-to-have-versions of the same application or library run on the same page, Because they both need the same global symbol name, for example, MYAPP.long, dotted names to type and resolve at runtime, for example, MYAPP.utilities.array.A Global ConstructorUsing The sandbox would look like this:New

Document directory Problem Restrictions Solution Problem My goal is very simple, that is, to use code written by others in my own system, but this Code may pollute global variables or even be malicious and destructive. I want to ensure that the Code is correctly executed and Its Impact scope is fully controlled. This is the sandbox I want. Based on my own thoughts and discussions with some friends, I think I need to solve the following four probl

The sandbox mechanism (sandbox) in iOS is a security system that specifies that an application can only read files within a folder created for the app and cannot access content elsewhere. All non-code files are saved in this place, such as slices, sounds, attribute lists, and text files.(1), the application can operate in its own sandbox, but cannot access any ot
