js整数字符串转换为金额类型数据

function zhen(str) {var arr_1 = ["", "\u62fe", "\u4f70", "\u4edf", "\u4e07", "\u4ebf"], arr_2 = ["", "\u4e07", "\u4ebf"];var maskstr = arr_1.slice(1).join("");var arr2 = ["\u96f6", "\u58f9", "\u8d30", "\u53c1", "\u8086", "\u4f0d", "\u9646", "\u67d2", "\u634c", "\u7396"];var arr3 = new Array;var arr = str.split("");arr.reverse();var _step_ = 4;var _index_ = 0;var int1 = 0, int2 = 0;// varfor (var i = 0; i < arr.length; i++) {_index_ = i;int1 = _index_ % _step_;int2 = parseInt(_index_ / _step_);if (int2 > 0 & int1 == 0) {if (maskstr.indexOf(arr3[arr3.length - 1]) != -1) {arr3.pop();}arr3.push(arr_2[int2]);}if (arr[i] > 0) {if (int1 > 0) {arr3.push(arr_1[int1]);}}arr3.push(arr2[arr[i]]);}arr3.reverse();return arr3.join("");}

测试：

zhen('12345');

->"壹万贰仟叁佰肆拾伍"
