ar chked = obj.checked;
if(chked)
{
//eval("document.Form1.tr1.style ='DISPLAY:'");
window.document.getElementById("tr1").style.display ="";
window.document.getElementById("tr2").style.display ="none";
}
else
{
// eval("document.Form1.tr1.style ='DISPLAY:none'");
window.document.getElementById("tr1").style.display ="none";
window.document.getElementById("tr2").style.display ="";
}
少个字母V 应该是var chked = obj.checked;
