请教前辈一个JS自动关闭文本字段后如何重新开启

[sheng0306]

原来它是这样的·· 倒计时到设定时间时自动关闭文本输入框·····能不能改成倒计时到最后10的时候把倒计时时间的颜色换另外颜色··10秒结束然后 重新自动开启文本输入框 或者当它自动关闭文本输入框时 等待10后自动重新打开·····现在需要手动刷新一下才能重新提交 ··



function timer(intDiff){
var day=0,
hour=0,
minute=0,
second=0;//时间默认值
if(intDiff > 0){
day = Math.floor(intDiff / (60 * 60 * 24));
hour = Math.floor(intDiff / 3600);
minute = Math.floor(intDiff / 60) - (hour * 60);
second = Math.floor(intDiff) - (hour * 60 * 60) - (minute * 60);
}else{
clearTimeout(odds);
$(".bian_td_odds").html("暂时无法发表").removeClass("cur");
$(".bian_td_inp").html("请稍后在进行提交");
$(".bian_td_qiu").removeClass("cur");
clearTimeout(closeTime);
endFun();
}
if (hour <= 9) hour = '0' + hour;
if (minute <= 9) minute = '0' + minute;
if (second <= 9) second = '0' + second;
$('#hour_show').html(hour+' 时');
$('#minute_show').html(minute+' 分');
$('#second_show').html(second+' 秒');
intDiff--;
var closeTime = setTimeout("timer("+intDiff+")",1000);
}
