不要在循环内创建函数. -jslint错误 [英] Don't make functions within a loop. - jslint error

问题描述

我收到了这个jslint错误

I am getting this jslint error

不要在循环中创建函数.

Don't make functions within a loop.

我无法更改导致此问题的javascript，但是由于修改的限制，我无法更改.

I can't change the javascript that is causing this issue - however I cant, due to restrictions from modifying it.

因此，我想关闭此验证以检查特定JavaScript文件中的此错误.

So, I want to turn this validation to check for this error off in a particular javascript file.

是否可以解决此js错误?

Is this possible to do for this js error?

推荐答案

不，验证检查不是可选的.

No, that valildation check is not optional.

可能的解决方法:

// simple closure scoping i to the function.
for(var i = 0; i < 10; i++) {
    (function (index) {
         console.log(index);
     }(i));
}
// this works, however it's difficult to site read and not a blast to debug

解决方案:

// same exact output
function logger(index) {
    console.log(index);
}

// same output. Minus declaring all vars at the
// top of the function and console this passes jslint.
for(var i = 0; i < 10; i++) {
    logger(i);
}
