indexOf() returns the index in the array of the element you're searching for, or -1. So you can do:

var index = drawOrder.indexOf("aKey");
if (index != -1)
    drawOrder.splice(index, 1);

I'm not 100% this will answer your question cause is not clear at least to me.

If you want to remove the whole element but you are worried about founding the right index before actually splice the array you should use Array.indexOF

See this code below:

var data  = {
            'fnc':function(){ 
                      updatePosition(spriteID); 
                      drawSprite(spriteID); 
             },
             'type':'aabb'
            };

var drawOrder= [];
drawOrder.push(data);
console.log(drawOrder);
drawOrder.splice(drawOrder.indexOf(data), 1);
console.log(drawOrder);
