JS controls the conversion of Arabic numerals into Chinese uppercase sample code_javascript skills

Copy code The code is as follows:

function NoToChinese(num) {
if (!/^d *(.d*)?$/.test(num)) { alert("Number is wrong!"); return "Number is wrong!"; }
var AA = new Array("zero", "one ", "二", "三", "四", "五", "鲁", "旒", "八", "九");
var BB = new Array("", "十" , "hundred", "qian", "ten thousand", "hundred million", "point", "");
var a = ("" num).replace(/(^0*)/g, "" ).split("."), k = 0, re = "";
for (var i = a[0].length - 1; i >= 0; i--) {
switch (k) {
case 0: re = BB[7] re; break;
case 4: if (!new RegExp("0{4}\d{" (a[0].length - i - 1) "}$").test(a[0]))
re = BB[4] re; break;
case 8: re = BB[5] re; BB[7] = BB [5]; k = 0; break;
}
if (k % 4 == 2 && a[0].charAt(i 2) != 0 && a[0].charAt(i 1) == 0) re = AA[0] re;
if (a[0].charAt(i) != 0) re = AA[a[0].charAt(i)] BB[k % 4] re; k ;
}

if (a.length > 1) //Add the decimal part (if there is a decimal part)
{
re = BB[6];
for (var i = 0; i < a[1].length; i ) re = AA[a[1].charAt(i)];
}
return re;
}
