livequery 在 IE8 中不工作

Question

$('.DrpDwn option').livequery(function () {
            $(this).each(function () {
                $(this).addClass("DrpDwnItm");
            });
        });
$(function () {
        // updates Contract Id dropdown upon selection
        $(".DrpDwnItm").live('mouseover', function () {
            alert("text");
        });
    });

我已经尝试过：

$(function () {
        // updates Contract Id dropdown upon selection
        $(".DrpDwnItm").live('hover', function () {
            alert("text");
        });
    });

这在 FireFox 中工作正常。但IE8不行。我试图向每个选项标签添加一个类，其中选择标签有一个名为 DrpDwn 的类。任何人都可以提供任何想法来解释为什么吗？感谢
