asp.net中的一段javascript代码求解!!
addword.ascx页面:

代码如下:

<script language= "JavaScript " type= "text/javascript ">
function changeimage()
{
window.document.form1.showimage.src=document.form1.Addword1$guestPic.value;
}

<select name= "guestPic " id= "guestPic " onchange= "changeimage() " runat= "server ">
<option value= "..\Image\man\01.gif "> 01 </option>
<option value= "..\Image\man\02.gif "> 02 </option>
<option value= "..\Image\man\03.gif "> 03 </option>
<option value= "..\Image\man\04.gif "> 04 </option>
...
<img src= "../Image/man/01.gif " alt= " " width= "80 " height= "90 " id= "showimage " />

其中Addword1$guestPic名称为ascx插入到aspx页面所生成的控件名称.

此代码在ie中操作成功,在firefox更改选择项不能更改图片,请指教!!!

[解决办法]
function changeimage()
{
//window.document.form1.showimage.src=document.form1.Addword1$guestPic.value;
document.getElementById( "showimage ").src=document.getElementById( "Addword1$guestPic ").value;
}
