js整数字符串转换为金额类型数据(示例代码)

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;  
    // var   
    for (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]);
