asynchronous thread is initiated, the newly initiated asynchronous thread does not affect the previously initiated thread, and all the originating threads continue to execute, as in the following example, until all threads of the user close the program end running. ）；The state can be null or a reference to the object to pass in each time the asynchronous thread is invoked;Callback is a method that passes a parameter of type object, the return value is a delegate type of void, and is customized

parameter. The difference between the two is the second argument: Apply passes in an array of parameters, which is the combination of multiple parameters into an array, and call is passed in as a call parameter (starting with the second argument).Under JavaScript Strict mode (strict mode), when a function is called, the first parameter becomes the value of this, even if the parameter is not an object.In JavaScript's non-strict mode, if the value of the first parameter is null or undefined, it

The return value to Nodejs has been seen in the Hello function.Each modification is completed and the same goes back to the command line using npm install recompile.

When we novice write python, we tend to invoke modules from other directories to work (as the veteran knows) and sometimes do not know what to do.What should we do if we need to call script d.py under directory A c.py the script under directory B?We need to use the module OS and sys to add the a directory to the environment variable:In script d.pyImport Sys,osbase_path=os.path.dirname (Os.path.dirname (Os.path.abspath (__file__))) Sys.path.append (Base_path) From modules Import Calprint (Cal.add

Would like to find a "elegant" approach, similar to C # in invoking the C + + method when the invoke and the like. Did not find, then think, in fact, there is no need to write directly, it is the most elegant. Just less than the intelligence of VS, a little bit unaccustomed.Cause of the matter:Want to write a table with a similar TreeView function, with the Jquey.load method, the event complete when you want to append row below the current line, but failed, there is a syntax error.
