我有一系列texfields,我想格式化为货币。优选地,这可以在飞行中完成但至少是onblur。我所说的货币格式是349507 - > $ 349507。有可能吗?
我更喜欢HTML / CSS / JS解决方案,因为我需要更少的解释。我对jQuery一点也不熟悉。
非常感谢任何帮助。

这是我很久以前用逗号格式化数字的一些代码。一个例子是formatNumber(349507, 0, 2, true)
→"349,507.00"
。
// Reformats a number by inserting commas and padding out the number of digits
// and decimal places.
//
// Parameters:
// number: The number to format. All non-numeric characters are
// stripped out first.
// digits: The minimum number of digits to the left of the decimal
// point. The extra places are padded with zeros.
// decimalPlaces: The number of places after the decimal point, or zero to
// omit the decimal point.
// withCommas: True to insert commas every 3 places, false to omit them.
function formatNumber(number, digits, decimalPlaces, withCommas)
{
number = number.toString();
var simpleNumber = '';
// Strips out the dollar sign and commas.
for (var i = 0; i < number.length; ++i)
{
if ("0123456789.".indexOf(number.charAt(i)) >= 0)
simpleNumber += number.charAt(i);
}
number = parseFloat(simpleNumber);
if (isNaN(number)) number = 0;
if (withCommas == null) withCommas = false;
if (digits == 0) digits = 1;
var integerPart = (decimalPlaces > 0 ? Math.floor(number) : Math.round(number));
var string = "";
for (var i = 0; i < digits || integerPart > 0; ++i)
{
// Insert a comma every three digits.
if (withCommas && string.match(/^\d\d\d/))
string = "," + string;
string = (integerPart % 10) + string;
integerPart = Math.floor(integerPart / 10);
}
if (decimalPlaces > 0)
{
number -= Math.floor(number);
number *= Math.pow(10, decimalPlaces);
string += "." + formatNumber(number, decimalPlaces, 0);
}
return string;
}
您可以在onblur
事件处理程序中使用它,如下所示:
<input type="text" onblur="this.value = '$' + formatNumber(this.value, 0, 0, true)" />
这会在数字上加上逗号,并在前面拍一个美元符号。

Google首先搜索“javascript格式货币”
http://www.web-source.net/web_development/currency_formatting.htm
function CurrencyFormatted(amount)
{
var i = parseFloat(amount);
if(isNaN(i)) { i = 0.00; }
var minus = '';
if(i < 0) { minus = '-'; }
i = Math.abs(i);
i = parseInt((i + .005) * 100);
i = i / 100;
s = new String(i);
if(s.indexOf('.') < 0) { s += '.00'; }
if(s.indexOf('.') == (s.length - 2)) { s += '0'; }
s = minus + s;
return s;
}
