Direction ' s syringe error. Lost announcement

[kalena]

If I write this, the block will go left:

$(".templateWindow").animate({"left" : "-150%"}, 300 , funcCallBack);

And if there's a mistake,

var direction = "left";
$(".templateWindow").animate({direction : "-150%"}, 300 , funcCallBack);

Direction ' s syringe error. Lost announcement. What is this about?

When you write {direction: ..} , you're making the object's direction. Differences between {direction: .. } and {"direction": ..} No. In order to take the variable name of the properties you want to ask, you need to this:

var direction = "left";
var opts={}
opts[direction]="-150%";
$(".templateWindow").animate(opts, 300 , funcCallBack);
