提问by
Hey guys I'm making a simple memory game. I used some setTimeout. Until a point, It was going good. After that I wanted to add a stopwatch. And bom. I got this error.
嘿伙计们，我正在制作一个简单的记忆游戏。我使用了一些 setTimeout。直到某一点，它进展顺利。之后我想添加一个秒表。和邦。我收到了这个错误。
Uncaught TypeError: Property 'setTimeout' of object [object Object] is not a function
未捕获的类型错误：对象 [object Object] 的属性“setTimeout”不是函数
at this line;
在这一行；
function counter(){
ctxCounter.font="100pt Arial";
var fillT= setTimeout( function(){ctxCounter.fillText("3",270,340);} , 100);
var clearT= setTimeout( function(){counterClear();} , 1000);
}
and my stopWatch part's code. After adding this line I get the error written above. But without stopwatch everything works perfectly.
和我的秒表部分的代码。添加此行后，我收到上面写的错误。但是没有秒表，一切都完美无缺。
var timer=0;
var running=false;
function startPause(){
if(running==false){
running=true;
increment();
}
else running=false;
}
function reset(){
timer=0;
running=false;
}
function increment(){
if(running==true){
window.setTimeout=(
function(){
var mins= Math.floor(timer/600);
var secs= Math.floor(timer/10);
var tenths= timer%1000;
var all= mins+":"+secs+":"+tenths;
console.log(all);
increment();
},100);
}
}
I've stuck here for two days. Please, helm me.
我已经在这里卡了两天了。请掌舵我

You have a bug at the incrementfunction, there was a =after window.setTimeout
你有一个错误的increment功能，有一个=之后window.setTimeout
function increment(){
if(running==true){
window.setTimeout(
function(){
var mins= Math.floor(timer/600);
var secs= Math.floor(timer/10);
var tenths= timer%1000;
var all= mins+":"+secs+":"+tenths;
console.log(all);
increment();
},100);
}
}

The problem is with this line of code:
问题在于这行代码：
window.setTimeout=( ... );
回答by Joachim Isaksson
setTimeoutis normally a function, not a variable. You're reassigning it to the value 100 in your statement;
setTimeout通常是一个函数，而不是一个变量。您在语句中将其重新分配给值 100；
window.setTimeout=(function(){...}, 100);
Next time you try to call it, it's not a function anymore.
下次尝试调用它时，它不再是一个函数。
