jquery - 删除 "$"+ sum.toFixed(2)

Question

我正在使用 Pengoworks jquery 计算器，并且不希望我的总和被四舍五入。即:如果总和为 19.99，则四舍五入为 19。

我“认为”它在这里:“$”+ sum.toFixed(2)

        //Reforats..   $496.00  -->  496
        // Makes it workable
        var myArray = g_total.split('$');
        var myNewArray = myArray[1].split('.');


        //Submits the value to the #this works on line 391
        $('#thisworks').val(myNewArray[0]);

    }

    </script>

Answer 1

var myNewArray = myArray[1].split('.'); 将创建一个如下所示的数组:

myArray = ["19", "99"];

如果你希望它返回 19.99，你可以更改:

$('#thisworks').val(myNewArray[0]);

至:

$('#thisworks').val(myNewArray.join('.'));

或者您可以在拆分之前使用该值:

$('#thisworks').val(myArray[1]);

我不确定这些是否是最好的解决方案，但它应该可以发挥作用。
