规则详解

This rule enforces consistent spacing inside an open block token and the next token on the same line. This rule also enforces consistent spacing inside a close block token and previous token on the same line.

配置项

This rule has a string option:

• "always" (default) requires one or more spaces
• "never" disallows spaces

always

选项 "always" 默认值的 错误 代码示例：

/*eslint block-spacing: "error"*/

function foo() {return true;}
if (foo) { bar = 0;}
function baz() {let i = 0;
    return i;
}

class C {
    static {this.bar = 0;}
}

选项 "always" 默认值的 正确 代码示例：

/*eslint block-spacing: "error"*/

function foo() { return true; }
if (foo) { bar = 0; }

class C {
    static { this.bar = 0; }
}

never

选项 "never" 的 错误 代码示例：

/*eslint block-spacing: ["error", "never"]*/

function foo() { return true; }
if (foo) { bar = 0;}

class C {
    static { this.bar = 0; }
}

选项 "never" 的 正确 代码示例：

/*eslint block-spacing: ["error", "never"]*/

function foo() {return true;}
if (foo) {bar = 0;}

class C {
    static {this.bar = 0;}
}

禁用建议

If you don't want to be notified about spacing style inside of blocks, you can safely disable this rule.
