Javascript阿拉伯数字转化中国大写数字的函数代码_javascript技巧



主要函数代码：
代码如下:
function Chinese(num)
{
if(!/^\d*(\.\d*)?$/.test(num))
{
alert("你输入的不是数字，请重新输入!");
return false;
}
var AA = new Array("零","壹","贰","叁","肆","伍","陆","柒","捌","玖");
var BB = new Array("","拾","佰","仟","万","亿","点","");
var a = (""+ num).replace(/(^0*)/g, "").split("."), k = 0, re = "";
for(var i=a[0].length-1; i>=0; i--)
{
switch(k)
{
case 0 :
re = BB[7] + re;
break;
case 4 :
if(!new RegExp("0{4}\\d{"+ (a[0].length-i-1) +"}$").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)=="0" && a[0].charAt(i+2) != "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) {
re += BB[6];
for(var i=0; i}
return re;
}

使用方法：
代码如下:
function TrunToChina()
{
var num= 123456789;
　　alert(Chinese(num));
}
TrunToChina();

效果演示
function TrunToChina() { var num= 123456789; 　　alert(Chinese(num)); } TrunToChina(); function Chinese(num) { if(!/^\d*(\.\d*)?$/.test(num)) { alert("你输入的不是数字，请重新输入!"); return false; } var AA = new Array("零","壹","贰","叁","肆","伍","陆","柒","捌","玖"); var BB = new Array("","拾","佰","仟","万","亿","点",""); var a = (""+ num).replace(/(^0*)/g, "").split("."), k = 0, re = ""; for(var i=a[0].length-1; i>=0; i--) { switch(k) { case 0 : re = BB[7] + re; break; case 4 : if(!new RegExp("0{4}\\d{"+ (a[0].length-i-1) +"}$").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)=="0" && a[0].charAt(i+2) != "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) { re += BB[6]; for(var i=0; i
