Useless setTimeout call (missing quotes around argument?)
提问by kosta5
I have this sniplet of code in jQuery
我在 jQuery 中有这段代码
$element.parent().children().last().hide().show('slide', {direction : 'left'}, 700, function () {
$element.delay(2000, function() {
$element.parent().children().last().hide('slide', {direction: 'left'}, 700);
reload_table(question_number);
//delay ends here
});
});
delayis declared as:
delay声明为：
jQuery.fn.delay = function(time,func){
return this.each(function(){
setTimeout(func,time);
});
};
Now I get the error:
现在我得到错误：
useless setTimeout call (missing quotes around argument?)

I agree with wsbaser. I had the additional instance of needed to pass information to the function, and for simplicity used:
我同意 wsbaser。我有一个需要将信息传递给函数的额外实例，为简单起见，使用了：
setTimeout(function(){ updateStatus(myData) } , 5000);
The argument needs to be a function and not a function being called. Firefox caught this error, chrome let it go.
参数必须是一个函数，而不是被调用的函数。Firefox 发现了这个错误，chrome 让它过去了。

Just for reference if someone stumbles upon this question and is looking for a possible answer. I got the exact same error message as the initial poster because I was mixing up the setTimeoutarguments order.
如果有人偶然发现这个问题并正在寻找可能的答案，仅供参考。我收到与初始海报完全相同的错误消息，因为我混淆了setTimeout参数顺序。
This:
这个：
setTimeout(25, function(){
spotlight.intro.find('#intro').ellipsis();
});
... gave me the error message. I changed the function to this:
...给了我错误信息。我将功能更改为：
setTimeout(function(){
spotlight.intro.find('#intro').ellipsis();
}, 25);
And my problem was solved.
我的问题解决了。

The problem was in Firefox 3. It is not handling some elements properly => Element is completely omitted in the tree and ignored -> hence my original problem
问题出在 Firefox 3 中。它没有正确处理某些元素 => 元素在树中完全省略并被忽略 -> 因此是我原来的问题
