Javascript函数格式化为货币

Javascript Function to Format as Money

本问题已经有最佳答案，请猛点这里访问。

我有一个脚本，我传给它一个字符串，它将返回格式为美元的字符串。因此，如果我发送它"10000"它将返回"$ 10,000.00"现在的问题是，当我发送它"1000000"(100万美元)时，它返回"$ 1,000.00"，因为它只设置为基于一组零进行解析。这是我的脚本，如何调整它以占两组零(100万美元)？

String.prototype.formatMoney = function(places, symbol, thousand, decimal) {
if((this).match(/^\$/) && (this).indexOf(',') != -1 && (this).indexOf('.') != -1) {
return this;
}
places = !isNaN(places = Math.abs(places)) ? places : 2;
symbol = symbol !== undefined ? symbol :"$";
thousand = thousand ||",";
decimal = decimal ||".";
var number = Number(((this).replace('$','')).replace(',','')),
negative = number < 0 ?"-" :"",
i = parseInt(number = Math.abs(+number || 0).toFixed(places), 10) +"",
j = (j = i.length) > 3 ? j % 3 : 0;
return negative + symbol + (j ? i.substr(0, j) + thousand :"") + i.substr(j).replace(/(\d{3})(?=\d)/g,"$1" + thousand) + (places ? decimal + Math.abs(number - i).toFixed(places).slice(2) :""); };

function formatMoney(number) {
return number.toLocaleString('en-US', { style: 'currency', currency: 'USD' });
}

console.log(formatMoney(10000)); // $10,000.00
console.log(formatMoney(1000000)); // $1,000,000.00

给它一个镜头，它寻找一个小数分隔符但你可以删除该部分，如果你喜欢：
