            alert($('#object1').height());
        }; 
    </script>
    <script type="text/javascript" src="jquery-1.7.2.js"></script>
</head>
<body>
    <object id="object1" height="205" width="246">

    Hiya demo http://jsfiddle.net/keXRf/3/ (using attr) or you can always set the css like here and use .css http://jsfiddle.net/LAp2c/

    link: http://api.jquery.com/height/ 🙂

    Note: since attributes height= is used in your case; you can use attr and that will give you desired output, but the link should help you to understand better.

    $('#object1').attr("height")

    also extra info: you can assign .css("height", 205) for consistancy across bwoser, there is a good discussion in the link I shared above.

    further: The difference between .css('height') and .height() is that the latter returns a unit-less pixel value (for example, 400) while the former returns a value with units intact (for example, 400px). The .height() method is recommended when an element’s height needs to be used in a mathematical calculation.
