alert();不执行，奇怪，大家帮下忙

Answer 1

alert()里没值啊，弄个字符串进去  alert('x')

Answer 2

不弄个字符串进去，也会弹出的？现在主要是不执行alert();

Answer 3

代码木有问题。jQuery文件正确加载了吗？（你用的是绝对路径，要在服务器上访问才有效）。

Answer 4

    <script type="text/javascript" src="/js/jquery-1.4.4.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            alert();
            $(".kcss41-1 img").bind({
                "mouseover": function () {
                    $(this).css({ "cursor": "pointer" });
                }
                 ,"mouseout": function () {
                     $(this).css({ "cursor": "pointer" });
                 }
            });
        });
    </script>
我这样写   alert();  可以执行加载应该没问题把

Answer 5

真奇怪  我在  窗体加载事件里  加了个  alert()；alert(); 被执行后，
            $(".kcss41-1 img").bind({
                "mouseover": function () {
                    alert();
                    $(this).css({ "cursor": "pointer" });
                }
                 ,"mouseout": function () {
                     $(this).css({ "cursor": "pointer" });
                 }
            });
这个代码就执行了，
