Firstly, don't use eval() to do this. There's no need and that opens up your site to vulnerabilities if you are in any way using user input as part of that (directly or indirectly). The right way to do this is:

<div id="div">This is a test</div>

with CSS:

#div { padding: 15px; background: yellow; }

and Javascript:

function slideObject(side) {
  var anim = {opacity: 0};
  anim["margin" + side] = "-1000px";
  $("#div").animate(anim, 1000);
}

$(function() {
  slideObject("Left");
});

You'll note that the opacity value is changed to 0. hide is not a valid value for opacity.

Basically you create the anonymous object and then assign a dynamic property using [].
