So I know you are talking about arrays in your post but your “array” you give to us is actually an object. Major shocker, I know… Notice the array [ ] vs object { } brackets.<\/p>\n

But this isn’t actually a bad thing in your case. You won’t need to loop over all items in an array at all!! Let me show you.<\/p>\n

You can access the keys of the object by array notation in javascript. (still following?) The basic way to do that is:<\/p>\n

object['key']           \/\/accessing by array notation\n<\/code><\/pre>\n
or<\/p>\n
object.key              \/\/accesing by dot notation\n<\/code><\/pre>\n
And since you’re talking about returning, I’m presuming your talking about functions. Take a look at the following search function using a check on the object named collection with array notation<\/p>\n<\/p>\n
\n
\n
var collection = {3412124539: 1, 3412124540: 1, 3412124577: 2, 3412124590: 1, 3412124602: 1, 3412124605: 1, 3412124607: 1, 3412124617: 1, 3412124629: 1, 3412124630: 1, 4709502367: 1, 4709502349: 1, 4709502326: 1, 4708510268: 1, 4708510060: 1}\r\n\r\nfunction search(inWhat, forWhat, equalsWhat){\r\n  if(inWhat[forWhat] == equalsWhat)\r\n    return 'returned cause '+forWhat+' is '+equalsWhat;\r\n}\r\n\r\nvar returnValue = search(collection, 3412124577, 2);\r\n\r\n\/\/ ---- outputting the returnValue here\r\ndocument.write(returnValue);<\/code><\/pre>\n<\/div>\n<\/div><\/div>\n
