?input输入钱币时格式化,但保存的时候又格式回来:
.
function outputMoney(number)
{
number=number.replace(/,/g,””);
if (number==””) return “”;
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);
}
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);
}
