例 1 ， 使数字 1111111 变成 11.111.111.00 ， 保留两位小数。
复制代码代码如下:
<Html>
<head>
<type skrip = "Teks/JavaScript">
fungsi outputmoney (angka) {
angka = number.replace (//,/g, "");
if (isnan (angka) || angka == "") return "";
angka = math.round (angka * 100) / 100;
if (angka <0)
return ' -' + outputDollars (math.floor (math.abs (angka) - 0) + '') + outputcents (math.abs (angka) - 0);
kalau tidak
return outputDollars (math.floor (angka - 0) + '') + outputcents (angka - 0);
}
// 格式化金额
fungsi outputDollars (angka) {
if (number.length <= 3)
return (number == ''? '0': number);
kalau tidak {
var mod = number.length % 3;
var output = (mod == 0? '': (number.substring (0, mod)));
untuk (i = 0; i <math.floor (number.length / 3); i ++) {
if ((mod == 0) && (i == 0))
output + = number.substring (mod + 3 * i, mod + 3 * i + 3);
kalau tidak
output + = ',' + number.substring (mod + 3 * i, mod + 3 * i + 3);
}
return (output);
}
}
fungsi outputcents (jumlah) {
Jumlah = Math.round (((Jumlah) - Math.floor (Jumlah)) * 100);
pengembalian (jumlah <10? '.0' + Jumlah: '.' + Jumlah);
}
</script>
</head>
<body>
<input type = text maxlength = "8" id = "test" oNblur = "this.value = outputMoney (this.value);" >
</body>
