我找到了一些有用的帖子,但没有直接回答我的问题,所以这里有具体的问题:
为了磨练我有限的jQuery技能,我创建了一个拆分比尔/小费计算器,根据以下输入计算点击按钮的金额:账单总额,提示百分比,人数。
然而,当我点击按钮时,什么也没发生。这是jQuery代码:
$(document).ready(function() {
$('button').click(function(){
var Total = $('.Total').val();
var Tip = $('.Tip').val();
var NumberOfPeople = $('.NumberOfPeople').val();
var AdjTotal = (((Tip/100)*Total)+Total).toFixed(2);
var Result = (AdjTotal/NumberOfPeople).toFixed(2);
if(isNaN(AdjTotal)) {
$('.result').remove();
$('.error').remove();
$('.price').append('<p class="error">Please enter valid numbers into the above fields.</p>');
}
else {
$('.error').remove();
$('.result').remove();
$('.price').append('<p class="result">Your total is $' + AdjTotal + ' ' + 'and each person owes: $' + Result + '.</p>');
}
});
});
HTML:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="style.css" />
<script src='script.js'></script>
<title>Split the Bill</title>
</head>
<body>
<div class="header">
<h1>Split the Bill</h1>
</div>
<div>
<table>
<tbody>
<tr>
<td align="right">
Bill Total: $
</td>
<td text-align="left">
<input class="Total" type="text" name="Total">
</td>
</tr>
<tr>
<td align="right">
Tip Percentage:
</td>
<td text-align="left">
<input class="Tip" type="text" name="Tip"> %
</td>
</tr>
<tr>
<td align="right">
Number of People:
</td>
<td colspan=3>
<input class="NumberOfPeople" type="text" name="Number of People">
</td>
</tr>
<tr>
<td colspan=4 align="right">
<button>Calculate</button>
</td>
</tr>
</tbody>
</table>
</div>
<div class="price">
</div>
</body>
</html>
感谢您的帮助!
答案 0 :(得分:1)
问题在于这一行:
var AdjTotal = (((Tip/100)*Total)+Total).toFixed(2);
Total是一个字符串。你需要强迫它成为一个数字:
var AdjTotal = (((Tip/100)*Total)+Total/1).toFixed(2);
