TypeError：未定义不是对象 [英] TypeError: undefined is not an object

问题描述

onmouseover 命令遇到问题。我的HTML代码中有少量代码（请参阅底部），当我尝试在Safari 7上运行它时，出现以下错误：

I'm having problems with the onmouseover command. I've got this little bit of code (see bottom) in my HTML code and when I try to run it on Safari 7 I get the following error:

TypeError：未定义不是对象（评估
'document.images.siz3.src ='images / shirts / img_3siz_grey.jpg''）
onmouseover

TypeError: undefined is not an object (evaluating 'document.images.siz3.src='images/shirts/img_3siz_grey.jpg'') onmouseover

出了什么问题？我找不到任何可能出错的信息。 img 应该定义为 siz1 ，不是吗？

What's the problem? I can't find anything that could be wrong. The img should be defined as siz1, shouldn't it?

也许有人可以提供帮助，我敢肯定答案很简单，但我只是没有看到它。

Maybe someone could help, I'm sure the answer's easy and I'm just not seeing it.

<a href="menu/latein/r-z/vfc/vfc.html" onmouseover="document.images.siz1.src='images/shirts/img_1siz_grey.jpg'" onmouseout="document.images.siz1.src='images/shirts/img_1_siz.jpg'" name="tshirts">
<img src="images/shirts/img_1_siz.jpg" name="siz1"  alt="Vivat floreat crescat" width="195px" height="135px"></img>

推荐答案

在这里类似问题 name = siz1 应该是 name = siz1 将 替换为

Looks like problem in here name="siz1" should be name="siz1" replace " to "
