小数点两位,及大写

在input中添加:

onblur="doub(this);chineseNumber(document.all('apply.checkMoneySum').value,'checkMoneySumBig')"

//金额保留两位小数
function doub(ctrlName)
{
  if(ctrlName.value != "")
  ctrlName.value=parseFloat(ctrlName.value).toFixed(2);

}

//金钱数字转人民币大写 num 就是数字,tarfield 指填充到那里显示中文
function chineseNumber(num,tarfield)
{
 if(""==num)
 {
  document.all(tarfield).value="";
  return;
 }
 if(parseFloat(num) == 0)
 {
  document.all(tarfield).value="零圆整";
  return;
 }
 if (""==num || isNaN(num) || num > Math.pow(10, 12)) return ""

 var unit1= new Array("万亿", "")
 var numArray = num.toString().split(".")

   {
