In practical applications, we often encounter such a scenario, when the page is completed after loading to do something: binding events, Dom operation of some nodes, and so on.
The most commonly used is the OnLoad event of window, and the actual effect of the event is: when the page parsing/dom tree is completed and completed, such as pictures, scripts, style sheets and even all the resources in the IFRAME download before triggering.
This is a bit too "late" for many practical applications, an

concept of scope is similar to that in other languages. Each time a function is called, it enters the scope of a function. After the function is returned, returns the scope before the call.
The syntax style of JS is similar to that of C/C ++, but the implementation of the scope is different from that of C/C ++. Instead of using the "stack" method, the list is used, the procedure is as follows (as described in ecma262 ):The scope of any execution context is implemented by the scope chain.When a
