max-statements
max-statements规则允许您指定函数中允许的最大语句数。
function foo() {
var bar = 1; // one statement
var baz = 2; // two statements
var qux = 3; // three statements
}规则细节
此规则强制实现功能块中允许的最大数量的语句。
选项
此规则有一个数字或对象选项：
"max"（默认值10）强制允许在功能块中允许的最大语句数量不推荐使用：maximum不推荐使用对象属性; 请改用对象属性max。此规则有一个对象选项：
"ignoreTopLevelFunctions": true忽略顶层函数
max
此规则的默认代码错误代码示例{ "max": 10 }：
/*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.
};具有默认选项的此规则的正确代码示例{ "max": 10 }：
/*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;
};
}ignoreTopLevelFunctions
此规则的附加正确代码示例包含以下{ "max": 10 }, { "ignoreTopLevelFunctions": true }选项：
/*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;
