JQuery. Map (array, callback(elementOfArray, indexInArray))
Returns: an Array
Feel the jquery map method is very useful, I would like to share with you.
Method replaces an array or a single object with new content.
Example of an application: get a set of checkbox values, separated by English commas, and splice them.
In CSDN code editor, dare not flatter really, I'm jsFiddle created the above example, attached to the link: http://jsfiddle.net/dV8eh/.
