The use of MooTools method in Ajax

Core.js

Function: $extend Copy all the properties of the second parameter object to the first parameter object.

Functions: $merge Merging a group of objects to generate a new object

Functions: $each iteration groups (including unconventional arrays, such as collection objects, arguments objects, or Ojbect objects returned by the built-in getElementsByTagName method)

Function: $pick Returns the first non-undefined item in the argument list; If all is undefined, NULL is returned

Function: $random returns a random integer within a specified interval

Function: $splat wrap incoming arguments into an array

Function: $time return the current timestamp

Function: $try attempts to execute a given set of functions and returns the return value of the first function that executed successfully;

Functions: $type detecting types of incoming arguments

Function: $chk detection parameter value exists (not null, undefined, false, or "") or 0. Applies to situations where 0 is also treated as a prevailing condition.

Function: $clear Clear Timer (timeout or interval). Usually used in conjunction with Function:delay and Function:periodical methods.

Function: $defined detect whether a parameter value is defined

Function: $arguments to create a function that returns a specific item for an incoming parameter (see example)

Function: $empty an empty function that doesn't do anything. Typical application: The placeholder method for event listeners.

Function: $lambda to encapsulate the parameters passed in. That is, if the incoming parameter is a function, the function is returned as it is, and if it is another object, it returns a newly created function that does nothing else. Just return to the original object.
