max-statements
Enforce a maximum number of statements allowed in function blocks
max-statements 规则允许你指定一个函数中可以存在的最大语句数。
function foo() {
var bar = 1; // 一个语句
var baz = 2; // 两个语句
var qux = 3; // 三个语句
}
规则细节
这条规则强制规定了功能块中允许的最大语句数。
选项
这条规则有一个数字或对象选项：
"max"（默认为10）强制规定函数块中允许的最大语句数。
废弃：对象属性 "maximum" 已被废弃，请使用对象属性 "max" 代替。
此规则选项为对象：
"ignoreTopLevelFunctions": true忽略顶级函数
max
使用此规则与默认的 { "max": 10 } 选项的错误示例：
Open in Playground
/*eslint max-statements: ["error", 10]*/
/*eslint-env es6*/
function foo() {
var foo1 = 1;
var foo2 = 2;
var foo3 = 3;
var foo4 = 4;
var foo5 = 5;
var foo6 = 6;
var foo7 = 7;
var foo8 = 8;
var foo9 = 9;
var foo10 = 10;
var foo11 = 11; // Too many.
}
let foo = () => {
var foo1 = 1;
var foo2 = 2;
var foo3 = 3;
var foo4 = 4;
var foo5 = 5;
var foo6 = 6;
var foo7 = 7;
var foo8 = 8;
var foo9 = 9;
var foo10 = 10;
var foo11 = 11; // Too many.
};
使用此规则与默认的 { "max": 10 } 选项的正确示例：
Open in Playground
/*eslint max-statements: ["error", 10]*/
/*eslint-env es6*/
function foo() {
var foo1 = 1;
var foo2 = 2;
var foo3 = 3;
var foo4 = 4;
var foo5 = 5;
var foo6 = 6;
var foo7 = 7;
var foo8 = 8;
var foo9 = 9;
var foo10 = 10;
return function () {
// The number of statements in the inner function does not count toward the
// statement maximum.
return 42;
};
}
let foo = () => {
var foo1 = 1;
var foo2 = 2;
var foo3 = 3;
var foo4 = 4;
var foo5 = 5;
var foo6 = 6;
var foo7 = 7;
var foo8 = 8;
var foo9 = 9;
var foo10 = 10;
return function () {
// The number of statements in the inner function does not count toward the
// statement maximum.
return 42;
};
}
注意，这条规则不适用于类静态块，而且类静态块中的语句不算是包围函数的语句。
使用此规则与 { "max": 2 } 选项的正确示例：
Open in Playground
/*eslint max-statements: ["error", 2]*/
function foo() {
let one;
let two = class {
static {
let three;
let four;
let five;
if (six) {
let seven;
let eight;
let nine;
}
}
};
}
ignoreTopLevelFunctions
使用此规则与 { "max": 10 }, { "ignoreTopLevelFunctions": true } 选项的正确示例：
Open in Playground
/*eslint max-statements: ["error", 10, { "ignoreTopLevelFunctions": true }]*/
function foo() {
var foo1 = 1;
var foo2 = 2;
var foo3 = 3;
var foo4 = 4;
var foo5 = 5;
var foo6 = 6;
var foo7 = 7;
var foo8 = 8;
var foo9 = 9;
var foo10 = 10;
var foo11 = 11;
}
