For some reason, when I try to loop through a JavaScript array that has only one item, I get an error that the array is undefined. If I add another item to the array, no problem.
This works:
var myArray = new Array(-1, 1);
This doesn’t:
var myArray = new Array(1);
Any idea why? Am I missing something basic here?
UPDATE: Here is sample looping code:
function loop(thisArray) {
for (i = 0; i < thisArray.length; i++) {
alert(thisArray[i]);
}
}
and a test file.
UPDATE #2: Dougal posts a solution in the comments.
