Prototype - Enumerable min() Method


Advertisements


This method returns the minimum element (or element-based computation), or undefined if the enumeration is empty. Elements are either compared directly, or by first applying the iterator and comparing the returned values.

The optional context parameter is what the iterator function will be bound to. If used, the this keyword inside the iterator will point to the object given by the argument.

Syntax

Iterator.min([context]);

Return Value

Returns minimum value found.

Example

<html>
   <head>
      <title>Prototype examples</title>
      <script type = "text/javascript" src = "/javascript/prototype.js"></script>
      
      <script>
         function showResult() {
            alert("$R(1,10).min() : " +  $R(1,10).min() );
            // Returns 1.

            function Person(name, age) {
               this.name = name;
               this.age = age;
            }
            var john = new Person('John', 20);
            var mark = new Person('Mark', 35);
            var daisy = new Person('Daisy', 22);

            alert("Min Age:"+[john, mark, daisy].min(function(person) {
               return person.age ;
            }) );
         }
      </script>
   </head>
