数字格式化为金额格式 （3位一个逗号隔开）如：100,000.00

function outputmoney(number) {
	if (isNaN(number) || number == "") return "";
	number = Math.round(number * 100) / 100;
	if (number < 0)
		return '-' + outputdollars(Math.floor(Math.abs(number) - 0) + '') + outputcents(Math.abs(number) - 0);
	else
		return outputdollars(Math.floor(number - 0) + '') + outputcents(number - 0);
}
//格式化金额 
function outputdollars(number) {
	if (number.length <= 3)
		return (number == '' ? '0' : number);
	else {
		var mod = number.length % 3;
		var output = (mod == 0 ? '' : (number.substring(0, mod)));
		for (i = 0; i < Math.floor(number.length / 3); i++) {
			if ((mod == 0) && (i == 0))
				output += number.substring(mod + 3 * i, mod + 3 * i + 3);
			else
				output += ',' + number.substring(mod + 3 * i, mod + 3 * i + 3);
		}
		return (output);
	}
}


function outputcents(amount) {
	amount = Math.round(((amount) - Math.floor(amount)) * 100);
	return (amount < 10 ? '.0' + amount : '.' + amount);
}function outputmoney(number) {
	if (isNaN(numbe
