Sandbox mode can compensate for two deficiencies in the namespace pattern:
Using a unique global object as a global variable entry for a program makes it impossible to use two different versions of the API in the same program, so they use the same unique global object name, such as MyApp;
Longer nested objects make code writing and parsing slower;
Sand
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
){// Another sandboxed "box" object// This "box" is not the same// The "box" outside this function//...// Done with Ajax});// No trace of Ajax module here}); Code List 6: Nested sandbox instancesFrom the above examples, we can see that the sandbox mode is used to wrap all the code logic in a callback function. You can generate different instances based on differ
shows that you can initialize the sandbox objects multiple times, and you can even nest them without worrying about any conflicts between them.
Copy Code code as follows:
Sandbox (' Dom ', ' event ', function (box) {
Work with Dom and event

Another sandboxed "box" object
This ' box ' is not the same as

When the AdobeFlashPlayer plug-in is updated to 11.3, the sandbox feature (protection mode) is added to enhance the security of the browser. However, adding this technology requires more resources, it also makes the running of AdobeFlashPlayer more unstable. The Sandbox feature has not been applied to AdobeFlashPlayer for a long time. Since it is unstable
