用js实现小写金额转大写的方法

Answer 1

   var price = "3452,132.567";
    console.log(changePrice(price))
    function changePrice(price) {
        var decimal = price.split(".");
        var nums = decimal[0].split(",")
        var resAry = [];
        var str = ''
        resAry.push(strChange(decimal[1], 0));
        for (var j = nums.length - 1, n = 0, k = 0; j >= 0; j-- , k += 3, n++) {
            resAry.unshift(strChange(nums[j], k + 3));
        }
        for (var i = 0; i < resAry.length; i++) {
            str += resAry[i]
        }
        return str
    }
    function strChange(ary, j) {
        var decimalAry = ['厘', '分', '角', '元', '拾', '佰', '仟', '万', '拾', '佰', '仟', '亿']
        var numAry = ['零', '壹', '贰', '叁', '肆', '伍', '陆', '柒', '捌', '玖']
        var str = []
        var str2 = ''
        if (j == 0) {
            for (var m = 0; m < ary.length; m++) {
                str2 += numAry[ary[m]] + decimalAry[2 - j++]
            }
        } else {

            for (var i = ary.length - 1, n = 0; i >= 0; i-- , n++) {
                var item = ary[i]
                str.unshift(numAry[item] + decimalAry[j++])
            }
            for (var m = 0; m < str.length; m++) {
                str2 += str[m]
            }
        }

        return str2
    }
