Question

我无法使用javascript获取弹出窗口显示表格数据onmouseover当鼠标悬停在数据库中的表格中返回的图像时，现在问题我没有实际上得到onmouseover工作（前一个问题解决了）但得到了显示在mmsed上的每个图像的更改上的数据。

查询的im使用工作正常并且显示正确的数据但是在onmouseover上只显示应该只显示表中第一行的数据，第二行和后续行应该显示查询调用的不同数据（哪个有效，只是没有显示onmouseover）

请记住，此页面包含在我的index.php中，该页面包含我的所有.js和.css调用

                // between the popup and everything else (borders, mouse)

Answer 1

所有隐藏的表都具有相同的ID，但ID必须是唯一的。

提供链接作为ShowPop（）

的参数

<a onmouseover='ShowPop(this)' ....>

然后您将能够访问ShowPop（）中的预期目标：

function ShowPop(o)
{
popup($(o).next('div').html(), 400);
}

修改

关于评论：
目前我认为弹出窗口不会在任何浏览器中消除onmouseout（IE除外），因为你没有为ShowPop（）提供参数，在其他浏览器中需要从getTarget返回任何东西，因为他们不知道窗口。事件。

更改此行：

var t = getTarget(arguments.callee.caller.arguments[0]);

到

var t = arguments.callee.caller.arguments[0];

...因为当你接受我的建议时，链接已作为ShowPup（）的参数提供，因此无需调用getTarget（）。

onmouseover在表中的所有行上显示相同的数据
