不要把名字定义为delete 这个是javascript的关键字 改成delete1就可以了

{
total++;
}
}
alert(total);//check total value
if (total == 0){
document.form1.delete1.disabled = true;
document.form1.update.disabled = true;
}
else if (total >= 1){
document.form1.delete1.disabled = false;
document.form1.update.disabled = false;
}
}
function selectAll(){
var friends = document.form1.elements;
