所有类型的主题都专注于欧洲逗号问题,即如何将','更改为'。',但我还没有找到解决方案。
我希望用户能够以逗号值方式输入(例如 3,99 ),然后计算一些内容并在逗号中再输出一些内容。 if语句应该提到如果最后的价格(收益)变为负数,则变为红色(即不可能)。
我能够将这个点改为逗号并输出,但反过来我却眼花缭乱。到目前为止,这是我的代码:
我已经设法根据@Zirak的评论和一点点魔法来完成整个工作,请参阅下面的代码!
function dollarformat(num) {
num = num.toString().replace(/\u20ac/g, 'Euro');
if(isNaN(num)) num = "0";
cents = Math.floor((num*100+0.5)%100);
num = Math.floor((num*100+0.5)/100).toString();
if(cents < 10) cents = "0" + cents;
for (var i = 0; i < Math.floor((num.length-(1+i))/3); i++)
num = num.substring(0,num.length-(4*i+3))+','+num.substring(num.length-(4*i+3));
return (num + ',' + cents);}
$('#prijsnow').keyup(function(num) {
var comma = $(this).val().replace(',', '.');
$('#vat').text(dollarformat(comma / 119 * 100));
$('#earnings').text(dollarformat(comma / 119 * 25));
// 0.80 is the minimum amount, I've put it in hardcode (could be dynamic as well)
if (comma < 0.80) { $('#earnings').text(0); } else {$('#earnings').text(dollarformat(comma / 119 * 75 - 0.50))};
// Nice fix for the colour problem, easy CSS attribution
if (comma < 0.80) { $('#earnings').css("color","red"); }
if (comma > 0.80) { $('#earnings').css("color","green"); }
});

只要查看脚本就不应该有问题。
if (/\./.test(num))
num.replace('.', ',');
//Or if you want the other way around
if (/\,/.test(num))
num.replace(',', '.');
对于负价格,您可以使用类:
if( $(earnings).val() < 0 )
$(earnings).addClass('negativeVal');
在你的CSS中:
.negativeVal {
color : red;
}
另外,为了省去麻烦:您是否尝试使用split?

如上所述,解决此问题的可能方法是:
function dollarformat(num) {
num = num.toString().replace(/\u20ac/g, 'Euro');
if(isNaN(num)) num = "0";
cents = Math.floor((num*100+0.5)%100);
num = Math.floor((num*100+0.5)/100).toString();
if(cents < 10) cents = "0" + cents;
for (var i = 0; i < Math.floor((num.length-(1+i))/3); i++)
num = num.substring(0,num.length-(4*i+3))+','+num.substring(num.length-(4*i+3));
return (num + ',' + cents);}
$('#prijsnow').keyup(function(num) {
var comma = $(this).val().replace(',', '.');
$('#vat').text(dollarformat(comma / 119 * 100));
$('#earnings').text(dollarformat(comma / 119 * 25));
// 0.80 is the minimum amount, I've put it in hardcode (could be dynamic as well)
if (comma < 0.80) { $('#earnings').text(0); } else {$('#earnings').text(dollarformat(comma / 119 * 75 - 0.50))};
// Nice fix for the colour problem, easy CSS attribution
if (comma < 0.80) { $('#earnings').css("color","red"); }
if (comma > 0.80) { $('#earnings').css("color","green"); }
});
