这是一段java代码.
<!--
tPopWait=1;
tPopShow=6000;
showPopStep=6;
popOpacity=85;
fontcolor="#023055";
bgcolor="#ffffff";
bordercolor="#7ca9ed";
sPop=null;curShow=null;tFadeOut=null;tFadeIn=null;tFadeWaiting=null;

document.write("<style type='text/css'id='defaultPopStyle'>");
document.write(".cPopText { background-color: " + bgcolor + ";color:" + fontcolor + "; border: 1px " + bordercolor + " solid;font-color: font-size: 12px; padding-right: 4px; padding-left: 4px; height: 20px; padding-top: 2px; padding-bottom: 2px; filter: Alpha(Opacity=0)}");
document.write("</style>");
document.write("<div id='dypopLayer' style='position:absolute;z-index:1000;' class='cPopText'></div>");

function showPopupText(){
var o=event.srcElement;
MouseX
