一、js代码

复制代码代码如下:

//***********默认设置定义.*********************  
tPopWait=50;//停留tWait豪秒后显示提示。  
tPopShow=5000;//显示tShow豪秒后关闭提示  
showPopStep=20; 
popOpacity=99; 

//***************内部变量定义*****************  
sPop=null; 
curShow=null; 
tFadeOut=null; 
tFadeIn=null; 
tFadeWaiting=null; 

document.write("<mce:styletype="text/css"id="defaultPopStyle"><!-- 
"); 
document.write(".cPopText{line-break:normal;word-break:break-all;background-color:#FEFCF3;color:#000000;border:1px#E7B68Csolid;padding-top:2px;padding-right:4px;padding-left:4px;padding-bottom:2px;font-size:12px;width:96px;filter:Alpha(Opacity=0)}"); 
document.write(" 
--></mce:style><styletype="text/css"id="defaultPopStyle"mce_bogus="1">"); 
document.write(".cPopText{line-break:normal;word-break:break-all;background-color:#FEFCF3;color:#000000;border:1px#E7B68Csolid;padding-top:2px;padding-right:4px;padding-left:4px;padding-bottom:2px;font-size:12px;width:96px;filter:Alpha(Opacity=0)}"); 
document.write("</style>"); 
document.write("<divid="dypopLayer"style="position:absolute;z-index:1000;"mce_style="position:absolute;z-index:1000;"class="cPopText"></div>"); 

 
functionshowPopupText(){ 
varo=event.srcElement; 
   MouseX=event.x; 
   MouseY=event.y; 
   if(o.alt!=null&&o.alt!=""){o.dypop=o.alt;o.alt=""}; 
       if(o.title!=null&&o.title!=""){o.dypop=o.title;o.title=""}; 
   if(o.dypop!=sPop){ 
           sPop=o.dypop; 
           clearTimeout(curShow); 
           clearTimeout(tFadeOut); 
           clearTimeout(tFadeIn); 
           clearTimeout(tFadeWaiting);  
           if(sPop==null||sPop==""){ 
               dypopLayer.innerHTML=""; 
               dypopLayer.style.filter="Alpha()"; 
               dypopLayer.filters.Alpha.opacity=0;  
               } 
           else{ 
               if(o.dyclass!=null)popStyle=o.dyclass  
                   elsepopStyle="cPopText"; 
               curShow=setTimeout("showIt()",tPopWait); 
           } 

   } 
} 

functionshowIt(){ 
       dypopLayer.className=popStyle; 
       dypopLayer.innerHTML=sPop; 
       popWidth=dypopLayer.clientWidth; 
       popHeight=dypopLayer.clientHeight; 
       if(MouseX+12+popWidth>document.body.clientWidth)popLeftAdjust=-popWidth-24 
           elsepopLeftAdjust=0; 
       if(MouseY+12+popHeight>document.body.clientHeight)popTopAdjust=-popHeight-24 
           elsepopTopAdjust=0; 

       dypopLayer.style.left=MouseX+12+document.body.scrollLeft+popLeftAdjust; 
       dypopLayer.style.top=MouseY+12+document.body.scrollTop+popTopAdjust; 
       dypopLayer.style.filter="Alpha(Opacity=0)"; 
       fadeOut(); 
} 

functionfadeOut(){ 
   if(dypopLayer.filters.Alpha.opacity<popOpacity){ 
       dypopLayer.filters.Alpha.opacity+=showPopStep; 
       tFadeOut=setTimeout("fadeOut()",1); 
       } 
       else{ 
           dypopLayer.filters.Alpha.opacity=popOpacity; 
           tFadeWaiting=setTimeout("fadeIn()",tPopShow); 
           } 
} 

functionfadeIn(){ 
   if(dypopLayer.filters.Alpha.opacity>0){ 
       dypopLayer.filters.Alpha.opacity-=1; 
       tFadeIn=setTimeout("fadeIn()",1); 
       } 
} 
document.onmouseover=showPopupText; 

二、html代码包含js代码即可，使用范例

<ahref="../UpLoadFile/200911784060017.jpg"target="_blank"title="<imgsrc=../UpLoadFile/200911784060017.jpg />">大</a> <ahref="../UpLoadFile/200911784060018.jpg"target="_blank"title="<imgsrc=../UpLoadFile/200911784060018.jpgwidth=96height=70/>">小</a>
