This is a simple loop to check for a partial key in an Array

/**
 * Extend the Array object
 * @param searchValue is the string to search for
 * @returns Returns all matches
*/

Array.prototype.searchFor = function(searchValue) {
   
 var pattern = new RegExp('^'+searchValue+'');
 var matches = [];
 
 for (var key in this) {    	
  if (pattern.test(key)) {
    matches.push(key);        	
  }    			
 }
 return matches;
};

/**

* Extend the Array object

* @param searchValue is the string to search for

* @returns Returns all matches

Array.prototype.searchFor = function(searchValue) {

var pattern = new RegExp('^'+searchValue+'');

var matches = [];

for (var key in this) {

if (pattern.test(key)) {

matches.push(key);

}

return matches;

};

Use it like this

var searchValue = "checkForMe";
var searchArray = [];
var matches = searchArray.searchFor(searchValue);

var searchValue = "checkForMe";

var searchArray = [];

var matches = searchArray.searchFor(searchValue);

I am using something similar to look though a huge word/key index and output matching keys that link to a Data object.
