1.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();
document.write(
);

document.onmouseover=showpopuptext;
2.html代码包含js代码即可，使用范例
具体的看脚本之家给出的测试代码。
