我目前在下面有一个javascript 代码,它在处理货币格式(即500.00 美元)时将总计计算为只读文本字段。我遇到的问题是,当以货币格式 (MinusSignNegative) 即 ($500.00) 而不是 -$500.00 输入多个负数时,如何处理计算。我目前在总计中遇到 NaN 错误。
任何人都可以提供解决方案吗?
<SCRIPT LANGUAGE="JavaScript">
<!--
function total(what,number) {
var grandTotal = 0;
for (var i=0;i<number;i++) {
if (what.elements['price' + i].value.replace(/\$|\,/g,'') == '')
what.elements['price' + i].value.replace(/\$|\,/g,'') == '0.00';
grandTotal += (what.elements['price' + i].value.replace(/\$|\,/g,'') - 0);
}
what.grandTotal.value = (Math.round(grandTotal*100)/100);
}
