For JavaScript timers, there is no pause and restart in the strict sense, only clear stop, but it can be achieved through some 'eyesores'

allChild[index].onclick = function(){//当点击目标且满足下面的条件时 让计时器时间暂停
if(gamInt == true){
$("#tu").css("display","block");
//计时器暂停(清除定时器)
clearInterval(countdownTimer);
//延迟2s后游戏继续 计时器暂停结束
setTimeout(function(){
// 移除所有的图片
removeImgFun();
$("#tu").css("display","none");
imgNum++;
if(imgNum >= 10){
imgNum = 10;
}
createImgFun();
//定时器继续接之前的时间增加 继续播放(将之前的定时器重新引用一次 包括定时器的名字(必须要有 不然容易引起电脑死机)完整引入)
countdownTimer = setInterval(function (){
countdownNum -= 0.01;
//保留两位小数
countdownNum = countdownNum.toFixed(2);
if (countdownNum <= 0){
clearInterval(countdownTimer);
//游戏结束
alert("游戏结束!");
//房祖名不能再点击(分数不再计数)
gamInt = false;
}
time.innerHTML = "倒计时:" + countdownNum + "秒";
},10);
},2000)
//计分
scores += 1;
score.innerHTML = "第" + scores + "关";
if(scores > 8){
$("#wc").css("display","block");
$("#haha").css("display","none");
$("#cj").on("click",award());
$("#sm").on("click",explain());
}
}
}
