jQuery - length()

Just like in javascript, the length() method returns the length of a string or an array.

In this jQuery example, it will make a list of all found <p> elements and store those results in an array. In this case, the .length property has the count of the array - the number of indexes, not the length a string. This is a property, not a method. There is no need for ().

Get Length Ex 1

Get Length Ex 2

$("#btnLength1").click(function ()
{
    $("#demo1").html("Number of P elements in this doc: " + $("p").length);
});

$("#btnLength2").click(function ()
{
    var introLength = $("#intro").html().length;
    $("#demo2").html("Length of P#intro: " + introLength);
});
