jQuery plugin

Options

Accepts three options:

• sequence [ARRAY] an array with either key codes or a string with special keys such as ENTER;
• enter [BOOL] if the enter key needs to be pressed at the end. Default: false;
• callback [FUNCTION] the JS function that needs to be called when the sequence is completed.
• once [BOOL OR STRING] true if only one time the sequence can be typed; false for multiple times (default); 'depends' looks at the return of the callback function: if true, the sequence can't be typed again.

Example

    $(window).typesequence({
      sequence: ['p', 'a', 's', 's', 'w', 'o', 'r', 'd'],
      enter: true,
      callback: function(){
        alert('Foo');
      }
    });
