JSLint，else和预期'}'和'else'错误之间只有一个空格 [英] JSLint, else and Expected exactly one space between '}' and 'else' error

问题描述

为什么 JSLint 报告代码：

 函数cos（a）{
 var b = 0; 
如果（a）{
 b = 1; 
} 
 else {
 b = 2; 
} 
 
返回b; 
} 
  

错误：

 第6行问题5：预计'}'和'else'之间只有一个空格。 
  

可以通过禁用 Tolerate messy white space 选项来关闭此错误JSLint。

或换句话说 - 为什么语法：
}否则{优于

  ... 
} 
 else {
 ... 
  

Google还使用语法与}否则{表单。

<但是我不明白为什么。 Google提到了隐式分号插入，但是在打开 {，而不是关闭一个。

Can的情况下Javascript在关闭}后插入分号如果阻止，即使下一个令牌是 else 指示？

抱歉我的问题有点混乱 - 我试图大声思考。

解决方案

JSLint基于Crockford的偏好（我在这种情况下分享）。

它是是一个更好的意见问题。

（虽然显然他的观点是对的;）

Why JSLint report in code:

function cos(a) {
    var b = 0;
    if (a) {
        b = 1;
    }
    else {
        b = 2;
    }

    return b;
}

error:

Problem at line 6 character 5: Expected exactly one space between '}' and 'else'.

This error can be turned off by disabling Tolerate messy white space option of JSLint.

Or in other words -- why syntax: } else { is better then

...
}
else {
...

Google also uses syntax with } else { form.

But I don't understand why. Google mentioned ''implicit semicolon insertion'', but in context of opening {, not closing one.

Can Javascript insert semicolon after closing } of if block even if next token is else instruction?

Sorry that my question is a bit chaotic -- I tried to think loud.

解决方案

JSLint is based on Crockford's preferences (which I share in this case).

It's a matter of opinion which is "better".

(Although clearly his opinion is right ;)
