ReactJs全局帮助函数

Question

function helperfunction1(a, b) {
    //does some work
    return someValue;
}

function helperfunction2(c, d) {
    //does some work
    return someOtherValue;
}

function helperfunction3(e, f) {
    //does some work
    return anotherValue;
}

function helperfunction4(a, c) {
    //does some work
    return someValueAgain;
}


var SomeComponent =
    React.createClass({

        //Has bunch of methods

        //Uses some helper functions

        render: function () {

        }

    });

var SomeOtherComponent =
    React.createClass({

        //Has bunch of methods

        //Uses some helper functions

        render: function () {

        }

    });

Answer 1

您可以从一个文件导出多个函数,而不需要任何反应：

helpers.js：

export function plus(a, b) {
  return a + b;
}

export function minus(a, b) {
  return a - b;
}

export function multiply(a, b) {
  return a * b;
}

export function divide(a, b) {
  return a / b;
}

然后可以导入所需的函数：

import { multiply, divide } from './Helpers'
