无法将结果数字格式化为十进制形式

为什么这不将 #total 显示为小数？ class="total" 中的输入值是以 2 位十进制格式存储该值的函数结果。显示行总计的函数工作正常，但是当我使用下面的代码在 qty 字段更改时对行进行总计时，垫子是正确的并且更改正确发生，但它采用 int 样式而不是货币格式（2 位小数）的地方）。我也尝试过 Precision，没有任何改变。

$('[name^=qty]').change(function(){
    var sum = 0;
    $('input.total').each(function() {
        sum += $(this).val();
    });

    $('#total').val(sum).toFixed(2);
    });

以下是对每行进行总计的代码

function Tot(x,price,y) {
var total = CurrencyFormatted(x*price);
var v = document.getElementById(y);
v.setAttribute('value',total);}

所有这些函数都运行良好，正确总计并按预期更新，但总计字段中的小数位除外。

下面是我为每一行使用的 html，然后是总计

<td>$<input id="t1" disabled="disabled" size="8" value="0.00" class="total" />
...
<input disabled="disabled" id="total" name="total" size="8" value="0.00" />

css 中没有任何内容会改变类或表结构中数字的格式。我完全不知所措，但希望有人能看到我看不到的东西。先感谢您。

Why would this not show #total as a decimal?
The value of the inputs in class="total" are a function result that stores the value in 2 decimal format. The function to display the row totals works fine but when I use the below code to total the rows when the qty field changes, the mat is correct and the change takes place correctly, but it in an int style not a currency format (2 decimal places). I have tried toPrecision as well with no change.

$('[name^=qty]').change(function(){
    var sum = 0;
    $('input.total').each(function() {
        sum += $(this).val();
    });

    $('#total').val(sum).toFixed(2);
    });

Here is the code that totals each row

function Tot(x,price,y) {
var total = CurrencyFormatted(x*price);
var v = document.getElementById(y);
v.setAttribute('value',total);}

All of these functions run just fine, totaling correctly and updating as expected, with exception to the decimal places in the grand total field.

Below is the html that I am using for each row and then the total

<td>lt;input id="t1" disabled="disabled" size="8" value="0.00" class="total" />
...
<input disabled="disabled" id="total" name="total" size="8" value="0.00" />

There is nothing in the css that would change the format of the number either in the class or the table structure. I am at a complete loss, but hopefully someone will see something I don't. Thank you in advance.

$('input.total').each(function() {
    sum += parseFloat( $(this).val() );
});

$('#total').val( sum.toFixed(2) );

编辑，因为我很忙，所以我没有解释我的答案，格雷格·佩蒂特做了，所以这里是解释

你试图将 toFixed() 链接到不是数字的东西。此外，您没有将检索到的值转换为浮点数。 JS 可能已经处理了后者，但最好按照示例通过 parseFloat 运行它

$('input.total').each(function() {
    sum += parseFloat( $(this).val() );
});

$('#total').val( sum.toFixed(2) );

EDIT, since i was busy i didn't explain my answer, Greg Pettit did, so here's the explanation

You were trying to chain toFixed() to something that's not a number. Also, you weren't converting your retrieved values to floats. JS may have handled the latter, but better to run it through parseFloat as per sample
