You have to usemath round()andsplitto a given number to format numbers with commas and decimal places in JavaScript. RegEx is also required to do it. JavaScript format number with commas and decimal places A simple example code converts a given number into number value format with a comma ...
function formatNumberWithCommas(number) { number += ''; let [integer,decimal] = number.split('.'); const doSplit = (num,isInteger = true) => { if(num === '') return ''; if(isInteger) num = num.split('').reverse(); let str = []; for(let i = 0; i < num.length; i+...
numberWithCommas(12312124545);//'12,312,124,545' numberWithCommas(123121245.45);//'123,121,245.45' 1. 2. 3. 4. 5. 6. 7. 8. 9. 方法二、toLocaleString Number.prototype.toLocaleString。它是在JavaScript1.5(于 1999 年推出)中实现的,因此基本上所有主要浏览器都支持它。 var num = 12345.1234...
function formatNumberWithCommas(number) {number += '';let [integer,decimal] = number.split('.');const doSplit = (num,isInteger = true) => {if(num === '') return '';if(isInteger) num = num.split('').reverse();let str = [];for(let i = 0; i < num.length; i++){if(i ...
实现思路是将数字转换为字符数组,再循环整个数组, 每三位添加一个分隔逗号,最后再合并成字符串。 functionnumberWithCommas(x){x=x.toString();varpattern=/(-?\d+)(\d{3})/;while(pattern.test(x))x=x.replace(pattern,"$1,$2");returnx;}numberWithCommas(12312124545);//'12,312,124,545'number...
如果这是一个问题，您可以使用此功能：function numberWithCommas(x) {  ...
function formatNumberWithCommasCustom(number) { // 将数字转换为字符串,并去掉可能的小数点 let str = Math.floor(number).toString(); // 初始化结果字符串和一个计数器 let result = ''; let count = 0; // 从字符串的最后一个字符开始遍历 ...
The best way is to split the number format into several parts. function numberWithCommas(n) { var parts=n.toString().split("."); return parts[0].replace(/\B(?=(\d{3})+(?!\d))/g, ",") + (parts[1] ? "." + parts[1] : ""); } ...
The code starts off dividing the string into two parts (nStr and nStrEnd) if there is a decimal. A regular expression is used on nStr to add the commas. Then nStrEnd is added back. If the string didn't have nStrEnd temporarily removed, then the regular expression would format 10.0004...
