跨度jQuery的总和 [英] sum total from spans jQuery

问题描述

我正在尝试构建一个jQuery函数以计算跨度的总数

I am trying to build a jQuery function to calculate the total number from the span

var sumnormaltotal = 0;
$('span[id^="normaloffertotalspan"]').each(function () {
    var text = $(this).text();
    sumnormaltotal += parseInt(text, 10);
});

该功能运行正常，但是我有一些产品的价格以英镑符号开头，例如£1.50，但我的返回结果为1，而不是1.50，因此例如，如果我为特定产品选择金额2该价格返回的结果将是2而不是3，您能帮我提供一些想法吗?

The function is working perfectly but I have some products where the price is starting with a pound sign like £1.50, but my result back will be 1, not 1.50 so for example if I choose the amount 2 for the specific product with that price the result back will be 2 instead of 3 can you help me with some ideas please.

推荐答案

尝试一下..

var sum = 0;
$('.normaloffertotalspan').each(function() {
  sum += +$(this).text()||0;
});
$("#subtotal").text(sum);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div >

 <span class="normaloffertotalspan" id="option-1">11.11</span><br>
 <span class="normaloffertotalspan" id="option-2">22.5</span><br>
 <span class="normaloffertotalspan" id="option-3">33.33</span>

</div>

<h3>Subtotal = <span id="subtotal">0.00</span></h3>
