1、数字转人民币（小写）
/**
* 把数字转换成RMB格式
* @param v
* @returns {String}
*/
function RMBMoney(v){
v = (Math.round((v-0)*100))/100;
v = (v == Math.floor(v)) ? v + ".00" : ((v*10 == Math.floor(v*10)) ? v + "0" : v);

var ps = v.split('.');

4、IE6下字符串转成日期类型出现NaN问题
function parseISO8601(dateStringInRange) {
var isoExp = /^\s*(\d{4})-(\d\d)-(\d\d)\s*$/,
date = new Date(NaN), month,
parts = isoExp.exec(dateStringInRange);
if(parts) {
month = +parts[2];
date.setFullYear(parts[1], month - 1, parts[3]);
if(month != date.getMonth() + 1) {
date.setTime(NaN);
}
}
return date;
}
5、金额格式化为XXX,XXX,XXX.XX
function formatNum(num,n)
{
num = String(num.toFixed(n));
var re = /(-?\d+)(\d{3})/;
while(re.test(num)) num = num.replace(re,"$1,$2")
return num;
}
document.write(formatNum(1234005651.789,2));
