我想知道如何在我的 java 脚本中添加设计（边框/颜色）

我对代码没有经验，但可以快速学习

也许一些关于如何添加边框和颜色+框的提示真的很有帮助

另外，我希望答案只有 2 位小数而不是无穷大

谢谢 ：）

我的代码如下：

<html>
<head>
<script type = "text/javascript">



function convert() {
var Amount=document.getElementById('amount');
var Currency=document.getElementById('currency');
var Converted=document.getElementById('converted');
var Choice=document.getElementById('choice');
var AED=1;
var US=0.27;
var QR=0.99;
var SR=1.02;
var KD=0.0778;
var BD=0.102;

switch(document.converter.currency.value) {
case "US Dollars" :
document.converter.converted.value=US*document.converter.amount.value;
document.converter.choice.value=document.converter.currency.value;
break;
case "Qatar Riyal":
document.converter.converted.value=QR*document.converter.amount.value;
document.converter.choice.value=document.converter.currency.value;
break;
case "Saudi Riyal":
document.converter.converted.value=SR*document.converter.amount.value;
document.converter.choice.value=document.converter.currency.value;
break;
case "Kuwaiti Dinar":
document.converter.converted.value=KD*document.converter.amount.value;
document.converter.choice.value=document.converter.currency.value;
break;
case "Bahrain Dinar":
document.converter.converted.value=BD*document.converter.amount.value;
document.converter.choice.value=document.converter.currency.value;
break;
}

}
</script>

</head>

<body>
<div id="divWrapper">
<form name="converter" id="converter">
Enter amount in UAE Dirhams AED
<input name="amount"type="text" id="amount" size="7" />
<br /><br />
Please select a currency <select name="currency" id="currency">
<option>Please Choose One</option>
<option value="US Dollars">US Dollars</option>
<option value="Qatar Riyal">Qatar Riyal</option>
<option value="Saudi Riyal">Saudi Riyal</option>
<option value="Kuwaiti Dinar">Kuwaiti Dinar</option>
<option value="Bahrain Dinar">Bahrain Dinar</option>
</select><br /><br />
The amount is: 
<input name="converted" type="text" id="converted" value="" size="7"/>
in 
<input name="choice" type="text" id="choice" style="border:0px" value="">
<br /><br />
<input type="button" name="convt" id="convt" onclick="convert()" value="Convert" />
</form>
