The map method
The map method calls a given function on each element of a set. It is especially useful for getting or setting the values of a collection of elements. The map method returns a newly formed set of different elements and objects, unlike the each method, which returns the original set of elements.
Syntax
The elements themselves are available in the function, in the variable this, and their ordinal numbers in the set — in the variable index:
$(selector).map(function(index, element));
Example
Let's print a list of id element names separated by commas. We'll also use the get and join methods:
<p id="aaa">text1</p>
<p id="bbb">text2</p>
<p id="ccc">text3</p>
console.log(
$('p').map(
function() {
return this.id;
}
).get().join()
);
