Javascript isArray() : Check if an element/object is an Array

February 1, 2008 by Bramus!

The isArray() function over at BreakingPar.com looks great at first, but unfortunately does not work in Safari. This one here does work

// X-Browser isArray(), including Safari
function isArray(obj) {
    return obj.constructor == Array;
}

Elsewhere, javascript javascript, link

Thank you for this, it was the quick fix I needed, and it sorted the afore mentioned Webkit issue that the BreakingPar.com version had.

However, I found that if ‘obj’ was undefined. The code would break and an error would be returned.

To fix this, I simply added to you code to safeguard it from this:

function isArray(obj) {
if (typeof obj != “undefined”) {
return obj.constructor == Array;
} else
return false;
}

Hope this helps someone else!
