++复制代码++ 代码如下:

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]);
}
}
arr3.push(arr2[arr[i]]);
}
arr3.reverse();
<SPAN style="FONT-FAMILY: Consolas, 'Lucida Console', monospace; WHITE-SPACE: pre-wrap; COLOR: rgb(0,128,255)">return arr3.join("");</SPAN>
}

测试：

zhen('12345');
