input输入钱币时格式化,但保存的时候又格式回来  

<script>

else

return outputDollars(Math.floor(number-0) + '') + outputCents(number - 0);

}

function outputDollars(number)

{

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);

}

}

}

function outputCents(amount)
