How to check if an array index exists or not in javascript?
I am working with Titanium, my code looks like this: var currentData = new Array(); if(currentData[index]!==””||currentData[index]!==null||currentData[index]!==’null’) { Ti.API.info(“is exists ” + currentData[index]); return true; } else { return false; } I am passing an index to the currentData array. I still can’t detect a non-existing index using the above code. 21 Answers 21
