控制form中两个check不能同时选择
<form name= "form1 " method= "post " action= "aaaa.asp ">
<input name= "cancel_time " type= "checkbox " id= "cancel_time ">
是否改截止时间
<input name= "cancel_time2 " type= "checkbox " id= "cancel_time2 ">
是否改截止日期时间
<input type= "button " name= "Button " value= " 更 新 " class= "crystal " onClick= "javascript:submit_confirm(); ">
</form>
function submit_confirm() {
if(form1.endcancal_time.checked==true &&form1.endcancal_time2.checked==true){
alert( "“是否改截止日期”和“是否改截止日期时间”不能同时选择！ ");
return false;
}
else
{
document.form1.submit();
}
}
endcancal_time和endcancal_time2可以同时不选，可以任选一个，但不能同时选，我用上面的函数控制，没起到作用，请大家指点一下
