/**
 * 设置金钱格式
 * @param {Number} value [金钱数值]
 */
function Money(value, symbol = "￥") {
    if (value) {
        var pre = decimal = s1 = s2 = ‘‘;
        value = String(value)
        s1 = (value.split(‘.‘)[0]).split(‘‘).reverse().join(‘‘);
        decimal = value.split(‘.‘)[1] || ‘‘
        if (isNaN(Number(s1[s1.length - 1]))) {
            pre = s1[s1.length - 1];
            s1 = s1.substring(0, s1.length - 1);
        }
        for (var i = 0, n = s1.length; i < n; i++) {
            (i % 3 == 0 && i > 0 && s1) ? s2 += ‘,‘ + (s1[i] || ‘‘): s2 += (s1[i] || ‘‘)
        }
        return symbol + pre + s2.split(‘‘).reverse().join(‘‘) + (decimal ? ‘.‘ + decimal : ‘‘);
    } else if(value === 0){
        return symbol + value
    }
}

结果如下：
