鼠标悬停文本，然后在下面的IE8中更改图像

Question

我有一个用JavaScript制作的横幅，当你悬停在一个特定的文本上时，横幅中的图像会发生变化。

我想知道如何使它在ie8.中兼容

我用这个教程想出了js:

我也试着把鼠标移出去，然后图像就会改变。

以下是js代码：

<script type="text/javascript">function changeimage(towhat,url){if (document.images){document.images.targetimage.src=towhat.src gotolink=url}}functionwarp({window.location=gotolink}</script>
<script>var myimages=new Array()var gotolink="#"function preloadimages(){for (i=0;i<preloadimages.arguments.length;i++){myimages[i]=newImage()myimages[i].src=preloadimages.arguments[i]}}preloadimages("map_wm_hover.gif", "map_wm_hover2.gif","map_wm.gif")</script>

这是css：

<div id="base"><div id="mapcontainer"><a href="javascript:warp()"><img src="map_wm.gif" name="targetimage" border=0></a></div>

<div id="textcontainer"><div class="textboxinner1"><a href="index.html"onMouseover="changeimage(myimages[2],this.href)">8CCC REQUESTS/TALKBACK</a></div>
<div class="textboxinner2"><a href="index.html"onMouseover="changeimage(myimages[1],this.href)">Alice Springs  8952 7771</a></div>
<div class="textboxinner2"><a href="index.html"onMouseover="changeimage(myimages[0],this.href)">Tenant Creek 8952 7182</a></div>
<div class="textboxinner3"><span class="t3nonelink">...other contact details <a href="index.html" onMouseover="changeimage(myimages[2],this.href)">here</a></span></div>

我认为这是IE的一个问题，因为javascript中没有正确加载动画gif。一种解决方法是将图像放在HTML代码中的隐藏div中，而不是将它们加载到脚本中。一个积极的副作用是，这大大简化了javascript。看见http://jsfiddle.net/5pZLT/7

HTML:

<DIV id=base>
<DIV id=mapcontainer><A href="javascript:warp()"><IMG border=0 name=targetimage src ="http://www.keencloudmedia.com/skybluekangaroo/map_wm.gif"></A> </DIV>
<DIV id=textcontainer>
<DIV class=textboxinner1><A onmouseover=changeimage(2,this.href) 
href="index.html">8CCC REQUESTS/TALKBACK</A> </DIV>
<DIV class=textboxinner2><A onmouseover=changeimage(1,this.href) 
href="index.html">Alice Springs 8952 7771</A> </DIV>
<DIV class=textboxinner2><A onmouseover=changeimage(0,this.href) 
href="index.html">Tenant Creek 8952 7182</A> </DIV>
<DIV class=textboxinner3><SPAN class=t3nonelink>...other contact details <A 
onmouseover=changeimage(2,this.href) href="index.html">here</A></SPAN> 
</DIV></DIV></DIV><div id="hiddenImages" style="display: none">
<img src="http://www.keencloudmedia.com/skybluekangaroo/map_wm_hover.gif" name="hoverImage" />
<img src="http://www.keencloudmedia.com/skybluekangaroo/map_wm_hover2.gif" name="hoverImage2" />
<img src="http://www.keencloudmedia.com/skybluekangaroo/map_wm.gif" name="originalImage" />
</div>​

Javascript：

var gotolink = "#";
function changeimage(imageNumber, url) {
if (document.images) {
document.images.targetimage.src = 
document.getElementById('hiddenImages').children[imageNumber].src;
gotolink = url;
}
}

顺便说一句，有很多；s在您的原始代码中丢失，这可能会使它停止工作。
