jQuery: Multiply a number with 7.5

javascriptjquerycalculatorbigcartel

提问by curly_brackets

I'm about to design a webshop, build upon the Big Cartel webshop system. The nearest currency they use is Euro, but I want Danish Kroner (DKK), which is 7.5 of Euro.

我即将设计一个网上商店,建立在大卡特尔网上商店系统的基础上。他们使用的最接近的货币是欧元,但我想要丹麦克朗 (DKK),即 7.5 欧元。

How can I multiply the number within a div.price?

如何乘以 div.price 中的数字?

I've found "jQuery Calculate"-plugin, but I can't figure out how it works.

我找到了“jQuery 计算”插件,但我不知道它是如何工作的。

$('div.price').text(function(i,v) {
    return Math.round(parseInt(v * 100, 10) * 7.5) / 100;
});

$("div.price").each(function(){
 $(this).text(parseFloat($(this).text()) * 7.5);
});

But you really shouldn't be doing that with javascript.

但是你真的不应该用javascript来做。
