  1.   

    ducument[imgField].src=eval(newImg+".src")改成document[imgField].src=eval(newImg+".src")
      

  2.   

    <HTML>
    <HEAD>
    <TITLE>菜单</TITLE>
    <SCRIPT LANGUAGE=JAVASCRIPT TYPE="TEXT/JAVASCRIPT">
    if(document.images){
     
      flyOff=new Image
      tankOff=new Image  
      flyOff.src="http://expert.csdn.net/images/csdn.gif"
      tankOff.src="http://expert.csdn.net/images/jspd_wdzx_sqgg_ad.gif"}function chgImg(imgField,newImg){
      if(document.images)
      {
        eval(imgField).src=eval(newImg).src
      }
    }
    </SCRIPT>
    </HEAD>
    <BODY>
    <A HREF="123.html" onMouseover="chgImg('flyImg','flyOff')" onMouseout="chgImg('flyImg','tankOff')"><IMG SRC="http://expert.csdn.net/images/jspd_wdzx_sqgg_ad.gif" NAME="flyImg"></A>                                       
    </BODY>
    </HTML>

    document[imgField].src=eval(newImg+".src")
    改为
    eval(imgFiled).src=eval(newImg).src
    试试
