前言
haorooms博客之前总结了很多js的用法，例如数字三位分割等等，详细请看https://www.haorooms.com/post/js_qian_huobi_gs 这里面的黑科技介绍了toLocaleString，最近查了toLocaleString的兼容性，还是蛮好的，可以用起来。
number的toLocaleString 应用
// 1、将数字进行千分位切割展示
var num = 1331231
console.log(num.toLocaleString()) // 1,331,231 // 2、将数字转为货币样式
var number = 123456.789;
console.log(number.toLocaleString('zh', { style: 'currency', currency: 'EUR' })); //€123,456.79
console.log(number.toLocaleString('zh', { style: 'currency', currency: 'CNY' })); //¥123,456.79
console.log(number.toLocaleString('zh', { style: 'currency', currency: 'CNY',currencyDisplay:'code' })); //CNY 123,456.79
console.log(number.toLocaleString('zh', { style: 'currency', currency: 'CNY',currencyDisplay:'name' })); //123,456.79人民币
// 3、将数字转为百分比形式
var num1 = 0.12
var num2 = 2.45
console.log(num1.toLocaleString('zh',{style:'percent'})) // 12%
console.log(num2.toLocaleString('zh',{style:'percent'})) // 245%
// 4、转换为汉字
(123456789).toLocaleString('zh-hans-CN-u-nu-hanidec',{useGrouping:false})
//"一二三四五六七八九"
(123456789).toLocaleString('zh-hans-CN-u-nu-hanidec',{useGrouping:true})
//"一二三,四五六,七八九"
new Date().toLocaleString('zh-hans-CN-u-nu-hanidec')
//"二〇一八/一/三一 下午八:五四:五一"数组Array的 toLocaleString
var numArray = [12,564,'55',5,'8']
console.log(numArray.toLocaleString('zh')) // 12,564,55,5,8
var prices = ['￥7', 500, 8123, 12];
prices.toLocaleString('zh-CN', { style: 'currency', currency: 'CNY' }); //'￥7,¥500.00,¥8,123.00,¥12.00'Date的toLocaleString 应用
new Date().toLocaleString("zh-cn")
new Date().toLocaleString('en-GB', { timeZone: 'UTC' })关于timeZone的枚举
