# Prototype Enumerable include() Method

This method determines whether a given object is in the Enumerable or not, based on the == comparison operator. This is an alias of member() method.

If you need to check whether there is an element matching a given predicate, use any() method instead.

## Syntax:

    Iterator.include(object);

## Return Value :

- Returns true if finds given object otherwise false.

## Example:

    <html>
    <head>
    <title>Prototype examples</title>
    <script type="text/javascript"
       src="/javascript/prototype.js">
    </script>

    <script>

    function showResult(){

      alert("$R(1,15).include(10) : " + $R(1,15).include(10) );
      // Returns true

      alert("['hello', 'world'] : " + $R(1,15).include('HELLO') );
      // Returns false

    }

    </script>
    </head>

    <body>

      <p>Click the button to see the result.</p>
      <br />
      <br />
      <input type="button" value="Result" onclick="showResult();"/>

    </body>
    </html>
